Have you ever said something you wish you could take back? Maybe it was a comment muttered in the heat of the moment that hurt someone’s feelings. Or maybe you just had a night out full of silly antics that you wouldn’t want your boss or grandma to see.
These are completely normal occurrences that happen all the time. We’re human! We make mistakes and letting loose every now and again is good for us. When these scenarios happen in person, we’re able to apologize or explain ourselves; however, the social media age complicates things. High-def cameras and video recorders are in everyone’s pocket, meaning that in-person slip-ups or lapses in judgement can come back to haunt you in a cyberscheme known as doxing.
Doxing can be harmful to one’s reputation and can cost someone their job, their friends, or their privacy. Here are five things you should know about doxing, plus some tips on how to prevent it from happening to you.
The term doxing originated from the phrase “dropping documents/docs.” It refers to a situation where an enemy or a rival seeks to tarnish the reputation of someone else by releasing documents (aka dropping docs) about them. These documents often contain personally identifiable information (PII) – like full names, birthdates, addresses, employment details, financial information, phone numbers, email addresses – and private correspondences or embarrassing videos or photos. The doxer – or the person dropping the documents – will publish these private details online, whether that’s on a forum, on social media, or a blog.
Doxing is considered cyberbullying because it is a form of online harassment. The doxer often does so with the intent of drumming up widespread hate about the victim and having the release of these private details negatively affect the victim’s life, such as getting them fired from their job or breaking up a relationship.
Doxing happens most frequently to public figures, such as celebrities, politicians, streamers, and journalists. It is also a prevalent practice in the hacking community, where hackers reveal the identities of the real people behind forum usernames. However, anyone is susceptible to having their PII or sensitive photos or videos widely released on the internet for the sake of reputation sabotage. All it takes is for one scorned partner, a disgruntled coworker, or a disagreement to set a doxer on a warpath.
When the saboteur doesn’t have to dig into your past via the dark web or through hacking a personal device, doxing isn’t illegal. It’s malicious and can be emotionally damaging, but there is no law stopping a doxer from publishing the private details of someone else. Doxing crosses the line into a crime when it is accompanied by threats.
So, if a doxer didn’t hack a personal device or buy the PII off the dark web, where did they find these details? Oftentimes, people incriminate themselves with their social media footprint. What seems like ancient history in your social media timeline is again front and center after just a few minutes of scrolling.
Check out these tips that can lessen the chances of doxing happening to you:
In addition to the above tips, McAfee can help you fill in the gaps in your defense. McAfee Total Protection is an all-in-one privacy and identity protection service that includes all the tools you need to secure your PII and help you recover if identity theft occurs after a doxing incident. Personal Data Cleanup scans 40 risky data broker sites for your information. If you appear on any of those sites, McAfee will help you remove it to keep your PII out of a doxer’s hands.

“But everyone else has one.”
Those are familiar words to a parent, especially if you’re having the first smartphone conversation with your tween or pre-teen. In their mind, everyone else has a smartphone so they want a one too. But does “everyone” really have one? Well, your child isn’t wrong.
Our recent global study found that 76% of children aged 10 to 14 reported using a smartphone or mobile device, with Brazil leading the way at 95% and the U.S. trailing the global average at 65%.
Our figures show that younger children with smartphones and mobile devices make up a decisive majority of younger children overall.
Of course, just because everyone else has smartphone doesn’t mean that it’s necessarily right for your child and your family. After all, with a smartphone comes access to a wide and practically unfettered world of access to the internet, apps, social media, instant messaging, texting, and gaming, all within nearly constant reach. Put plainly, some tweens and pre-teens simply aren’t ready for that just yet, whether in terms of their maturity, habits, or ability to care for and use a device like that responsibly.
Yet from a parent’s standpoint, a first smartphone holds some major upsides. One of the top reasons parents give a child a smartphone is “to stay in touch,” and that’s understandable. There’s something reassuring knowing that your child is a call or text away—and that you can keep tabs on their whereabouts with GPS tracking. Likewise, it’s good to know that they can reach you easily too. Arguably, that may be a reason why some parents end up giving their children a smartphone a little sooner than they otherwise would.
However, you don’t need a smartphone to do to text, track, and talk with your child. You have alternatives.
One way to think about the first smartphone is that it’s something you ease into. In other words, if the internet is a pool, your child should learn to navigate the shallows with some simpler devices before diving into the deep end with a smartphone.
Introducing technology and internet usage in steps can build familiarity and confidence for them while giving you control. You can oversee their development, while establishing rules and expectations along the way. Then, when the time is right, they can indeed get their first smartphone.
But how to go about that?
It seems a lot of parents have had the same idea and device manufacturers have listened. They’ve come up with smartphone alternatives that give kids the chance to wade into the mobile internet, allowing them to get comfortable with device ownership and safety over time without making the direct leap to a fully featured smartphone. Let’s look at some of those options, along with a few other long-standing alternatives.
These small and ruggedly designed devices can clip to a belt loop, backpack, or simply fit in a pocket, giving you the ability to see your child’s location. In all, it’s quite like the “find my” functionality we have on our smartphones. When it comes to GPS trackers for kids, you’ll find a range of options and form factors, along with different features such as an S.O.S. button, “geofencing” that can send you an alert when your child enters or leaves a specific area (like home or school), and how often it sends an updated location (to regulate battery life).
Whichever GPS tracker you select, make sure it’s designed specifically for children. So-called “smart tags” designed to locate things like missing keys and wallets are just that—trackers designed to locate things, not children.
With GPS tracking and many other communication-friendly features for families, smart watches can give parents the reassurance they’re looking for while giving kids a cool piece of tech that they can enjoy. The field of options is wide, to say the least. Smart watches for kids can range anywhere from devices offered by mobile carriers like Verizon, T-Mobile, and Vodaphone to others from Apple, Explora, and Tick Talk. Because of that, you’ll want to do a bit of research to determine the right choice for you and your child.
Typical features include restricted texting and calling, and you’ll find that some devices are more durable and more water resistant than others, while yet others have cameras and simple games. Along those lines, you can select a smart watch that has a setting for “school time” so that it doesn’t become a distraction in class. Also, you’ll want to look closely at battery life, as some appear to do a better job of holding a charge than others.
Another relatively recent entry on the scene are smartphones designed specifically for children, which offer a great step toward full-blown smartphone ownership. These devices look, feel, and act like a smartphone, but without web browsing, app stores, and social media. Again, features will vary, yet there are ways kids can store and play music, stream it via Bluetooth to headphones or a speaker, and install apps that you approve of.
Some are paired with a parental control app that allows you to introduce more and more features over time as your child as you see fit—and that can screen texts from non-approved contacts before they reach your child. Again, a purchase like this one calls for some research, yet names like Gabb wireless and the Pinwheel phone offer a starting point.
The old reliable. Rugged and compact, and typically with a healthy battery life to boot, flip phones do what you need them to—help you and your child keep in touch. They’re still an option, even if your child may balk at the idea of a phone that’s “not as cool as a smartphone.” However, if we’re talking about introducing mobile devices and the mobile internet to our children in steps, the flip phone remains in the mix.
Some are just phones and nothing else, while other models can offer more functionality like cameras and slide-out keyboards for texting. And in keeping with the theme here, you’ll want to consider your options so you can pick the phone that has the features you want (and don’t want) for your child.
Despite what your younger tween or pre-teen might think, there’s no rush to get that first smartphone. And you know it too. You have time. Time to take eventual smartphone ownership in steps, with a device that keeps you in touch and that still works great for your child.
By easing into that first smartphone, you’ll find opportunities where you can monitor and guide their internet usage. You’ll also find plenty of moments to help your child start forming healthy habits around device ownership and care, etiquette, and safety online. In all, this approach can help you build a body of experience that will come in handy when that big day finally comes—first smartphone day.

Using a VPN on your smartphone can boost your privacy in a big way, particularly with all the data tracking that’s happening out there today.
For some time now, we’ve recommended a VPN when using public Wi-Fi in airports, libraries, hotels, and coffee shops. Given that these are public networks, a determined hacker can snoop on the other devices transmitting data on it. With a VPN, any connection becomes a secure connection, which includes public Wi-Fi. That advice still holds true. Yet there’s a good reason to use it on your smartphone all the time—for your privacy.
Let’s start with a quick look at the two big things a VPN does for you.
The bank-grade encryption used by a strong VPN shields your data and information while it’s in transit, which makes it terrifically difficult for hackers to spy on your connection. (Think of your data and information traveling through a tunnel that no one else can use or see into.) In that way, at VPN makes all kinds of online activities more secure—like banking, shopping, and checking up on your finances.
By masking your whereabouts and your IP address, along with encryption that helps keep your activities private, a VPN reduces the personal information that others can collect and track. That includes internet service providers, social media companies, businesses, app developers, websites, and others who gather your data for marketing purposes or for resale to third parties.
As far as your privacy is concerned, a VPN on a smartphone can be a smart move. There are a couple of reasons for that: first, because of the way smartphones have additional tracking technologies built in, and second, because of all the trackable data we create when using smartphones as frequently as we do—up to six hours per day for some.
As for how your smartphone is built, data collectors can harvest your personal information that reveals what you’re doing, when you’re doing it, and where you’re doing it as well. Several technologies allow them to pinpoint where you are at any given time, such as GPS and location services, along with Bluetooth connectivity and location tracking based on which cell phone tower you’re connected to. Even scanning a QR code with your phone can reveal location information. It can all get rather precise, which is of interest to advertisers, businesses, and even governments.
Next, think about all the activities you do on your phone, with a special emphasis on the apps you use and the data they create, about your health, your shopping habits, your travels, who you’re chatting with, and what content you’re posting online—just to name a few things. Once again, that information in of itself is valuable to data collectors. It becomes even more valuable when they know where you do these things.
Taken together, data broker companies readily gather this information from millions of devices, generating billions of data points, and create massive lists of targeted information. And that information gets quite specific. With some data brokers collecting hundreds and into the thousands of data points per person, they can provide interested buyers with a high-resolution snapshot of who you are, where you live, who’s in your family, your income, where you shop, what you like to buy—right on down to your favorite shampoo. And that’s just for starters.
It’s little surprise that all this data brokering activity fuels a global business estimated at $200 billion U.S. dollars a year.
How’s this happening? In large part by way of the privacy policies you may or may not have read.
Within those policies, device manufacturers, social media companies, app developers, and so on will detail what data they collect, under what conditions, what they do with it, and if they share or resell that data to other parties. However, if you’ve ever taken a dive into the fine print of a privacy policy, what’s stated there isn’t always clear. Now consider all the apps you have on your phone and the privacy policies associated with each one—your personal data privacy picture gets even less clear.
With digital data and information collection baked into so much of what we do online, it’s little wonder that more than 70% of people feel like their data privacy is out of their control.
Yet there are things you can do.
Using a VPN on your smartphone can make you far more anonymous online. A VPN can minimize the data that gets exposed as it transmits to and from your smartphone. As a result, companies and data brokers can potentially learn far less about you, your shopping, your travels, your habits, and any other information that they could possibly collect and otherwise profit from.
While you have free VPN options available, I suggest steering clear of them. As with many “free” services, there’s going to be some catch, often involving data collection. For example, some so-called “free VPNs” have served up tracking malware or actually collected private data and information for sale—the very things you want a VPN to prevent.
Given that this is your privacy we’re talking about, do a little background check. Has the VPN you’re considering been independently audited for security? The technology that powers ours undergoes a thorough audit every year. Search news articles and see if the VPN you’re looking at has a track record of collecting and selling data in any way. Again, with our VPN technology, we don’t log or track what you do online so your online activity remains private.
What about the information that’s already out there? Our Personal Data Cleanup can help you remove your personal information from high-risk data broker sites, so you can prevent it from being further collected and sold online. If you’re unsure if your data and information are out there, consider what one major data brokers has touted in the past—a reach of over 62 countries and the ability to reach over 2.5 billion consumers globally. With 5 billion internet users today, that accounts for half of the world’s online population. And that’s just one data broker alone.
Moreover, consider that data brokers acquire plenty of information from places other than your smartphone and other connected devices. They skim and collate public records associated with you, information purchased from retailers with loyalty card programs, not to mention census data, court records, and motor vehicle records. And that’s just a few of the many sources. Using our Personal Data Cleanup can help remove those sorts of records too.
Together, the combination of a VPN and Personal Data Cleanup can help you become far more private than before. With so much of our digital lives getting collected, tracked, and tabulated, often without our knowledge thanks to confusing privacy policies, taking control of your privacy makes sense and only gets easier to do thanks to the tools and services available to you.

In part one of this issue of our Black Hat USA NOC (Network Operations Center) blog, you will find:
Adapt and Overcome, by Jessica Bair Oppenheimer
In technology, we plan as best as we can, execute tactically with the resources and knowledge we have at the time, focus on the strategic mission, adjust as the circumstances require, collaborate, and improve; with transparency and humility. In short, we adapt and we overcome. This is the only way a community can have trust and grow, together. Every deployment comes with its challenges and Black Hat USA 2022 was no exception. Looking at the three Ps (people, process, platform), flexibility, communication, and an awesome Cisco platform allowed us to build and roll with the changes and challenges in the network. I am proud of the Cisco Meraki and Secure team members and our NOC partners.
The Buck Stops Here. Full stop. I heard a comment that the Wi-Fi service in the Expo Hall was “the worst I’ve ever experienced at a conference.” There were a lot of complaints about the Black Hat USA 2022 Wi-Fi network in the Expo Hall on 10 August. I also heard a lot of compliments about the network. Despite that the Wi-Fi and wired network was generally very good the most of the conference, and before my awesome colleagues share the many successes of designing, building, securing, managing, automating and tearing down one of the most hostile networks on Earth; I want to address where and how we adapted and what we did to fix the issues that arose, as we built an evolving, enterprise class network in a week.
First, a little history of how Cisco came to be the Official Network Provider of Black Hat USA 2022, after we were already successfully serving as the Official Mobile Device Management, Malware Analysis and Domain Name Service Provider. An Official Provider, as a Premium Partner, is not a sponsorship and no company can buy their way into the NOC for any amount of money. From the beginning of Black Hat 25 years ago, volunteers built the network for the conference rather than using the hotel network. This continues today, with the staff of Black Hat hand selecting trusted partners to build and secure the network.
After stepping up to help Black Hat with the network at Black Hat Asia, we had only two and a half months until Black Hat USA, in Las Vegas, 6-11 August 2022. Cisco was invited to build and secure the network for the much larger Black Hat USA flagship conference, affectionally known as ‘Hacker Summer Camp’, as the Official Network Equipment Provider. There were few other options, given the short timeframe to plan, supply chain difficulties in procuring the networking gear and assembling a team of network engineers, to join the Cisco Secure engineers and threat hunters. All the work, effort and loaned equipment were a gift from Cisco Meraki and Cisco Secure to the community.
We were proud to collaborate with NOC partners Gigamon, IronNet, Lumen, NetWitness and Palo Alto Networks; and work with Neil ‘Grifter’ Wyler, Bart Stump, Steve Fink and James Pope of Black Hat. We built strong bonds of familial ties over the years of challenges and joint successes. I encourage you to watch the replay of the Black Hat session An Inside Look at Defending the Black Hat Network with Bart and Grifter.
In June 2022, adjacent to Cisco Live Americas, the NOC partners met with Black Hat to plan the network. Cisco Meraki already donated 45 access points (APs), seven MS switches, and two Meraki MX security and SD-WAN appliances to Black Hat, for regional conferences.
I looked at the equipment list from 2019, that was documented in the Bart and Grifter presentation, and estimated we needed to source an additional 150 Cisco Meraki MR AP (with brackets and tripods) and 70+ Cisco Meraki MS switches to build the Black Hat USA network in just a few weeks. I wanted to be prepared for any changes or new requirements on-site. We turned to JW McIntire, who leads the network operations for Cisco Live and Cisco Impact. JW was enthusiastically supportive in helping identify the equipment within the Cisco Global Events inventory and giving his approval to utilize the equipment. A full thanks to those who made this possible is in the Acknowledgements below.
Over the week-long conference, we used all but three of the switches and all the APs.
We worked off the draft floor plans from 13 June 2022, for the training rooms, briefing rooms, support rooms, keynote rooms, conference public areas, registration, and of course the Expo Hall: over two million square feet of venue. We received updated plans for the training rooms, Expo Hall and support needs 12 days before we arrived on site. There were about 60 training rooms planned, each requiring their own SSID and Virtual Local Area Network, without host isolation. The ‘most access possible’ was the requirement, to use real world malware and attacks, without attacking other classrooms, attendees, sponsors or the rest of the world. Many of the training rooms changed again nine days before the start of the network build, as the number confirmed students rose or fell, we adjusted the AP assignments.
For switching allocation, we could not plan until we arrived onsite, to assess the conference needs and the placement of the cables in the walls of the conference center. The Black Hat USA network requires that every switch be replaced, so we always have full control of the network. Every network drop to place an AP and put the other end of a cable into the new switches in the closets costs Black Hat a lot of money. It also requires the time of ‘Doc’ – the lead network engineer at the Mandalay Bay, to whom we are all deeply grateful.
The most important mission of the NOC is Access, then Security, Visibility, Automation, etc. People pay thousands of dollars to attend the trainings and the briefings; and sponsors pay tens of thousands for their booth space. They need Access to have a successful conference experience.
With that background, let’s discuss the Wi-Fi in the Expo Hall. Cisco has a service to help customers do a methodical predictive survey of their space for the best allocation of their resources. We had 74 of the modern MR57 APs for the conference and prioritized their assignment in the Expo Hall and Registration. Specifications for MR57s include a 6 GHz 4×4:4, 5 GHz 4×4:4 and 2.4 GHz 4×4:4 radio to offer a combined tri–radio aggregate frame rate of 8.35 Gbps, with up to 4,804 Mbps in 6GHz band, 2,402 Mbps 5 GHz band and, 1,147 Mbps / 574 Mbps in the 2.4 GHz band based on 40MHz / 20MHz configuration. Technologies like transmit beamforming and enhanced receive sensitivity allow the MR57 to support a higher client density than typical enterprise-class access points, resulting in better performance for more clients, from each AP.
We donated top of the line gear for use at Black Hat USA. So, what went wrong on the first day in the Expo Hall? The survey came back with the following map and suggestions of 34 MR57s in the locations below. Many assumptions were made in pre-planning, since we did not know the shapes, sizes and materials of the booths that would be present inside the allocated spaces. We added an AP in the Arsenal Lab on the far-left side, after discussing the needs with Black Hat NOC leadership.
In the Entrance area (Bayside Foyer) of the Expo Hall (bottom of the map), you can see that coverage drops. There were four MR57s placed in the Bayside Foyer for iPad Registration and attendee Wi-Fi, so they could access their emails and obtain their QR code for scanning and badge printing.
I believed that would be sufficient and we allocated other APs to the rest of the conference areas. We had positive reports on coverage in most areas of the rest of the conference. When there were reported issues, we quickly deployed Cisco Meraki engineers or NOC technical associates. to confirm and were able to make changes in radio strength, broadcasting bands, SSIDs, etc. to fine tune the network. All while managing a large amount of new or changing network requirements, as the show expanded due to its success and was fully hybrid, with the increased streaming of the sponsored sessions, briefings and keynotes and remote Registration areas in hotels.
As the attendees queued up in mass outside of the Expo Hall on the morning of 10 August, the number of attendee devices connecting to the four MR57s in the foyer grew into the thousands. This degraded the performance of the Registration network. We adjusted by making the APs closest to the registration iPads only dedicated to the Registration. This fixed Registration lag but reduced the performance of the network for the attendees, as they waited to rush into the Expo Hall. From the site survey map, it is clear that the replacement APs were now needed in the Entrance for a connected mesh network, as you entered the Expo Hall from the Bayside foyer. Here lies Lesson 1: expected people flow should be taken into account in the RF design process.
Another challenge the morning of the Expo Hall opening was that five of the 57MRs inside were not yet connected to the Internet when it opened at 10am. The APs were installed three days earlier, then placed up on tripods the afternoon prior. However, the volume of newly requested network additions, to support the expanded hybrid element required the deployment of extra cables and switches. This cascaded down and delayed the conference center team from finalizing the Expo Hall line drops until into the afternoon. Lesson 2: Layer 1 is still king; without it, no Wi-Fi or power.
A major concern for the sponsors in their booths was that as the Expo Hall filled with excited attendees, the connectivity of the 900+ iOS devices used for lead management dropped. Part of this congestion was thousands of 2.4Ghz devices connected to the Expo Hall network. We monitored this and pushed as many as possible to 5Ghz, to relieve pressure on those airwaves. Lesson 3: With Wi-Fi 6e now available in certain countries, clean spectrum awaits, but our devices need to come along as well.
We also adjusted in the Cisco Meraki Systems Manager Mobile Device Management, to allow the iPhones for scanning to connect securely to the Mandalay Bay conference network, while still protecting your personal information with Cisco SecureX, Security Connector and Umbrella DNS, to ensure access as we expanded the network capacity in the Expo Hall. Lesson 4: Extreme security by default where you can control the end point. Do not compromise when dealing with PPI.
Using the Cisco Meraki dashboard access point location heat map and the health status of the network, we identified three places in the front of the Expo Hall to deploy additional drops with the Mandalay Bay network team. Since adding network drops takes some time (and costs Black Hat extra money), we took immediate steps to deploy more MS120 switches and eight additional APs at hot spots inside the Expo Hall with the densest client traffic, at no expense to Black Hat. Lesson 5: Footfall is not only about sales analytics. It does play a role into RF planning. Thereby, allowing for a data-driven design decision.
Above is the heat map of the conference Expo Hall at noon on 11 August. You can see the extra APs at the Entrance of the Expo Hall, connected by the three drops set up by the Mandalay Bay to the Cisco Meraki switches in the closets. Also, you can see the clusters of APs connected to the extra MS120 switches. At the same time, our lead Meraki engineer, Evan Basta, did a speed test from the center left of the Expo Hall.
As I am sharing lessons learned, I want to provide visibility to another situation encountered. On the afternoon of 9 August, the last day of training, a Black Hat attendee walked the hallways outside several training rooms and deliberately attacked the network, causing students and instructors not to be able to connect to their classes. The training rooms have host isolation removed and we designed the network to provide as much safe access as possible. The attacker took advantage of this openness, spoofed the SSIDs of the many training rooms and launched malicious attacks against the network.
We must allow real malware on the network for training, demonstrations and briefing sessions; while protecting the attendees from attack within the network from their fellow attendees and prevent bad actors from using the network to attack the Internet. It is a critical balance to ensure everyone has a safe experience, while still being able to learn from real world malware, vulnerabilities and malicious websites.
The attack vector was identified by a joint investigation of the NOC teams, initiated by the Cisco Meraki Air Marshal review. Note the exact same MAC addresses of the spoofed SSIDs and malicious broadcasts. A network protection measure was suggested by the Cisco Meraki engineering team to the NOC leadership. Permission was granted to test on one classroom, to confirm it stopped the attack, while not also disrupting the training. Lesson 6: The network-as-a-sensor will help mitigate issues but will not fix the human element.
Once confirmed, the measure was implemented network wide to return resiliency and access. The NOC team continued the investigation on the spoofed MAC addresses, using syslogs, firewall logs, etc. and identified the likely app and device used. An automated security alerting workflow was put in place to quickly identify if the attacker resumed/returned, so physical security could also intervene to revoke the badge and eject the attacker from the conference for violation of the Black Hat code of conduct.
I am grateful to the 20+ Cisco engineers, plus Talos Threat Hunters, deployed to the Mandalay Bay Convention Center, from the United States, Canada, Qatar and United Kingdom who made the Cisco contributions to the Black Hat USA 2022 NOC possible. I hope you will read on, to learn more lessons learned about the network and the part two blog about Cisco Secure in the NOC
Building the Hacker Summer Camp Network, by Evan Basta
It was the challenge of my career to take on the role of the lead network engineer for Black Hat USA. The lead engineer, who I replaced, was unable to travel from Singapore, just notifying us two weeks before we were scheduled to deploy to Las Vegas.
We prepared as much as possible before arrival, using the floor plans and the inventory of equipment that was ordered and on its way from the warehouse. We met with the Black Hat NOC leadership, partners and Mandalay Bay network engineers weekly on conference calls, adjusted what we could and then went to Black Hat, ready for a rapidly changing environment.
Our team was able to remain flexible and meet all the Black Hat requests that came in, thanks to the ability of the Cisco Meraki dashboard to manage the APs and switches from the cloud. Often, we were configuring the AP or switch as it was being transported to the location of the new network segment, laptop in hand.
For the construction of the Black Hat network, let’s start with availability. Registration and training rooms had priority for connectivity. iPads and iPhones needed secure connectivity to scan QR codes of registering attendees. Badge printers needed hardline access to the registration system. Training rooms all needed their separate wireless networks, for a safe sandbox for network defense and attack. Thousands of attendees attended, ready to download and upload terabytes of data through the main conference wireless network. All the keynotes, briefings and sponsored sessions needed to be recorded and streamed. Below are all the APs stacked up for assignment, including those assigned to the Expo Hall in the foreground.
All this connectivity was provided by Cisco Meraki access points and switches along with integrations into SecureX, Umbrella, and other Cisco platforms. We fielded a literal army of engineers to stand up the network in six days.
Let’s talk security and visibility. For a few days, the Black Hat network is one of the most hostile in the world. Attendees learn new exploits, download new tools, and are encouraged to test them out. Being able to drill down on attendee connection details and traffic was instrumental in ensuring attendees followed the Black Hat code of conduct.
On the wireless front, we made extensive use of our Radio Profiles to reduce interference by tuning power and channel settings. We enabled band steering to get more clients on the 5GHz bands versus 2.4GHz and watched the Location Heatmap like a hawk looking for hotspots and dead areas. Handling the barrage of wireless change requests – enable or disabling this SSID, moving VLANs (Virtual Local Area Networks), enabling tunneling for host isolation on the general conference Wi-Fi, mitigating attacks – was a snap with the Cisco Meraki Dashboard.
Floor Plan and Location Heatmap
On the first day of NOC setup, the Cisco team worked with the Mandalay Bay networking engineers to deploy core switches and map out the switches for the closets, according to the number of cables coming in from the training and briefing rooms. The floor plans in PDF were uploaded into the Meraki Dashboard; and with a little fine tuning, aligned perfectly with the Google Map.
Cisco Meraki APs were then placed physically in the venue meeting and training rooms. Having the APs named, as mentioned above, made this an easy task. This enabled accurate heatmap capability.
The Location Heatmap provided the capability to drill into the four levels of the conference, including the Expo Hall, lower level (North Conference Center), 2nd Floor and 3rd Floor. Below is the view of the entire conference.
Network Visibility
We were able to monitor the number of connected clients, network usage, the people passing by the network and location analytics, throughout the conference days. We provided visibility access to the Black Hat NOC management and the technology partners, along with full API (Application Programming Interface) access, so they could integrate with the network platform.
Alerts
Cisco Meraki alerts provide notification when something happens in the Dashboard. Default behavior is to be emailed when something happens. Obviously, emails got lost in the noise, at Black Hat Asia 2022, we made a web hook in Cisco SecureX orchestration to be able to consume Cisco Meraki alerts and send it to Slack (the messaging platform within the Black Hat NOC), using the native template in the Cisco Meraki Dashboard.
The alert kicked off if an AP or a switch lost connectivity. At Black Hat USA, we modified this to text alerts, as these were a priority. In the following example, we knew at the audio-visual team unplugged a switch to move it and were able to deploy technical associates from the NOC to ensure it was reconnected properly.
The Cisco Stack’s Potential in Action, by Paul Fidler
As we planned for Black Hat USA, the number of iOS devices to manage and protect rose from 300+ to over 900, and finally over 1,000.
The first amongst these was the use of the Cisco Meraki API. We were able to import the list of MAC addresses of the Cisco Meraki APs, to ensure that the APs were named appropriately and tagged, using a single source of truth document shared with the NOC management and partners, with the ability to update en masse at any time. Over three quarters of the AP configuration was able to be completed before arriving on site.
Meraki Systems Manager – Initial device enrollment and provisioning
We’ll start with the positive: When it comes to creating the design to manage X number of devices, it doesn’t matter if it’s 10 devices, or 10,000… And this was certainly true for Black Hat. The requirements were straightforward:
All this configuration was done ahead of time in the Meraki Dashboard, almost a month before the conference.
Now the negatives: Of all the events that the company who supplies the devices attends; Black Hat is the only one where devices are managed. Using mass deployment techniques like Apple’s Automated Device Enrollment, therefore, is not used. The company pre-stages the devices using Apple Configurator, which allows for both Supervision and Enrollment.
It became more difficult: Whilst the pre-staged devices were fine (other than having to handle all 1,000+ devices to turn Wi-Fi to Autojoin and opening the Meraki Systems Manager app [to give us Jailbreak and Location visibility]), an extra 100 devices were supplied that were not enrolled. As these devices were enrolled elsewhere from the prior Black Hat conferences, a team of around 10 people pitched in to restore each device, adding the Wi-Fi profile and then enrollment.
Fortunately, Apple Configurator can create Blueprints:
A Blueprint is essential a list of actions, in a particular order, that Apple Configurator can run through autonomously
But why did it need a team of ten? There were several limitations:
However, the task was completed in around three hours, given the limitations! If there’s one lesson to learn from this: Use Apple’s Automated Device Enrollment.
Command vs Profile
One of the slight nuances of Apple Mobile Device Manager is the difference between a ‘command’ and ‘profile’. Within the Meraki Systems Manager dashboard, we don’t highlight the difference between the two. But it’s important to know. A ‘profile’ is something that remains on the device: If there’s a state change on the device, or the user attempts something, the profile is always on there. However, a ‘command’ is exactly that: It’s sent once, and if something changes in the future, then the command won’t have any effect.
So, why is this highlighted here? Well, in some instances, some apps weren’t pushed successfully: You’d see them on the device, but with a cloud icon next to them. The only way to resolve this would be to remove the app, and then repost it. But we were also using a Homepage Layout, which put various apps on various pages. Pushing the app would result in it appearing on the wrong page. To ensure a consistent user experience, we would push the homepage profile again to devices to take effect.
Meraki BSSID Geolocation
We’ve mentioned this before in past Black Hat events, but, given the scale of The Mandalay Bay, it’s important to circle back to this. GPS is notoriously unreliable in conference centers like this, but it was still important to know where devices are. Because we’d ensured the correct placement of the Access Points on the floor plan, and because Systems Manager was in the same organisation, it ensured that the devices reported their location accurately! If one were to ‘walk’ we could wipe it remotely to protect your personal details.
Protection of PPI (Protected Private Information)
When the conference Registration closed on the last day and the Business Hall Sponsors all returned their iPhones, we were able to remotely wipe all the devices, removing all attendee data, prior to returning to the device contractor.
APIs
As mentioned elsewhere in this blog, this was a conference of APIs. Just the sheer scale of the conference resulted in the use of APIs. Various API projects included:
From a Systems Manager perspective, there were:
Port Security, by Ryan MacLennan, Ian Redden and Paul Fidler
During the Cisco Meraki deployment, we had a requirement to shutdown ports as they went inactive to prevent malicious actors from removing an official device and plugging in theirs. This ability is not directly built into the Cisco Meraki dashboard, so we built a workflow for the Black Hat customer, using the Cisco Meraki API. To achieve this, we created a small python script that was hosted as an AWS (Amazon Web Services) Lambda function and listened for webhooks from the Cisco Meraki Dashboard when a port went down. Initially this did solve our issue, but it was not fast enough, about five minutes from the time the port went down/a cable was unplugged. This proof of concept laid the groundwork to make the system better. We migrated from using a webhook in the Cisco Meraki Dashboard to using syslogs. We also moved the script from Lambda to a local server. Now, a python script was scanning for syslogs from the switches and when it saw a port down log, it will immediately call out to the locally hosted python script that calls out to the Cisco Meraki API and disabled the port.
This challenge had many setbacks and iterations while it was being built. Before we settled on listening for syslogs, we tried using SNMP polling. After figuring out the information we needed to use, we found that trying to poll SNMP would not work because SNMP would not report the port being down if the switch to another device was fast enough. This led us to believe we might not be able to do what we needed in a timely manner. After some deliberation with fellow NOC members, we started working on a script to listen for the port down syslogs. This became the best solution and provided immediate results. The ports would be disabled within milliseconds of going downThe diagram below shows an example of what will happen: If the Workshop Trainer’s device is un-plugged and a Threat Actor tries to plug into their port, a syslog is sent from the Cisco Meraki switch to our internal server hosting the python listener. Once the python script gets the request, it sends an API call to the Cisco Meraki API gateway and the Cisco Meraki cloud then tells the switch to disable the port that went down very briefly.
However, what was apparent was that the script was working TOO well! As discussed, several times already in this blog, the needs of the conference were very dynamic, changing on a minute-by-minute basis. This was certainly true in Registration and with the Audio-Visual teams. We discovered quickly that legitimate devices were being unplugged and plugged in to various ports, even if just temporarily. Of course, the script was so quick that it disabled ports before the users in registration knew what was happening. This resulted in NOC staff having to re-enable ports. So, more development was done. The task? For a given network tag, show the status of all the ports of all the switches. Given the number of switches at the conference, tags were used to reduce the amount of data being brought back, so it was easier to read and manage.
Mapping Meraki Location Data with Python, by Christian Clausen
In the blog post we published after Black Hat Asia 2022, we provided details on how to collect Bluetooth and Wi-Fi scanning data from a Meraki organization, for long-term storage and analysis. This augmented the location data provided by the Meraki dashboard, which is limited to 24-hours. Of course, the Meraki dashboard does more than just provide location data based on Wi-Fi and Bluetooth scanning from the access points. It also provides a neat heatmap generated from this data. We decided to take our long-term data project a step further and see if we could generate our own heatmap based on the data collected from the Meraki Scanning API.
The Folium Python library “builds on the data wrangling strengths of the Python ecosystem and the mapping strengths of the leaflet.js library” to provide all kinds of useful mapping functions. We can take location data (longitude and latitude) and plot them on lots of built-in map tiles from the likes of OpenStreetMap, MapBox, Stamen, and more. Among the available Folium plugins is a class called “HeatMapWithTime.” We can use this to plot our Meraki location data and have the resulting map animate the client’s movements.
Step 1: Collect the data
During the previous conference, we used a Docker container containing a couple Flask endpoints connected via ngrok to collect the large amount of data coming from Meraki. We re-used the same application stack this time around, but moved it out from behind ngrok into our own DMZ with a public domain and TLS (Transport Layer Security) certificate, to avoid any bandwidth limitations. We ended up with over 40GB of JSON data for the conference week to give to Black Hat!
Step 2: Format the data
Folium’s HeatMapWithTime plugin requires a “list of lists of points of time.” What we wanted to do is generate an ordered dictionary in Python that is indexed by the timestamp. The data we received from the Meraki API was formatted into “apFloor” labels provided by the admin when the access points are placed. Within each “apFloor” is a list of “observations” that contain information about individual clients spotted by the AP scanners, during the scanning interval.
Here’s what the data looked like straight from the Meraki API, with some dummy values:
The “observations” list is what we wanted to parse. It contains lots of useful information, but what we wanted is MAC address, latitude and longitude numbers, and timestamp:
We used Python to iterate through the observations and to eliminate the data we did not use. After a lot of data wrangling, de-duplicating MAC addresses, and bucketizing the observations into 15-minute increments, the resulting data structure looks like this:
Now that the data is in a usable format, we can feed it into Folium and see what kind of map we get back!
Step 3: Creating the map
Folium is designed to project points onto a map tile. Map tiles can show satellite images, streets, or terrain, and are projected onto a globe. In our case, however, we want to use the blueprint of the conference center. Folium’s allows for an image’s overlay to be added, and the bounds of the image to be set by specifying the coordinates for the top-left and bottom-right corners of image. Luckily, we can get this from the Meraki dashboard.
This enabled us to overlay the floorplan image on the map. Unfortunately, the map tiles themselves limit the amount of zoom available to the map visualization. Lucky for us, we did not care about the map tile now that we have the floorplan image. We passed “None” as the map tile source and finally received our data visualization and saved the map as an HTML file for Black Hat leadership.
We opened the HTML file, and we had an auto-playing heatmap that lets us zoom at far in as we want:
Detail at 1:30pm PT, on 10 August 2022 below.
To improve this going forward, the logical next steps would be to insert the data into a database for the Black Hat conference organizers, for quick retrieval and map generation. We can then start looking at advanced use-cases in the NOC, such as tracking individual a MAC address that may be producing suspicious traffic, by cross-referencing data from other sources (Umbrella, NetWitness, etc.).

Network Recovery, by Jessica Bair Oppenheimer
Once the final session ended, the Expo Hall closed and the steaming switched off, dozens of conference associates, technical associates, Mandalay Bay engineers and Cisco staff spread out through two million square feet and numerous switching closets to recover the equipment for inventory and packing. It took less than four hours to tear down a network that was built and evolved 11 days prior. Matt Vander Horst made a custom app to scan in each item, separating equipment donated to Black Hat from that which needed to be returned to the warehouse for the next global Cisco event.

Cisco Secure Social Channels
In part one of our Black Hat USA 2022 NOC blog, we discussed building the network with Meraki:
In this part two, we will discuss:
Cisco is a Premium Partner of the Black Hat NOC, and is the Official Wired & Wireless Network Equipment, Mobile Device Management, DNS (Domain Name Service) and Malware Analysis Provider of Black Hat.
Black Hat USA is my favorite part of my professional life each year. We had an incredible staff of 20 Cisco engineers to build and secure the network. Also, for the first time, we had two Talos Threat Hunters from the Talos Incident Response (TIR) team, providing unique perspectives and skills to the attacks on the network. I really appreciated the close collaboration with the Palo Alto Networks and NetWitness team members. We created new integrations and the NOC continued to serve as an incubator for innovation.
We must allow real malware on the network for training, demonstrations, and briefing sessions; while protecting the attendees from attack within the network from their fellow attendees and prevent bad actors using the network to attack the Internet. It is a critical balance to ensure everyone has a safe experience, while still being able to learn from real world malware, vulnerabilities, and malicious websites. So, context is what really matters when investigating a potential attack and bringing so many technologies together in SecureX really accelerated investigation and response (when needed).
All the Black Hat network traffic was supported by Meraki switches and wireless access points, using the latest Meraki gear donated by Cisco. Our Meraki team was able to block people from the Black Hat network, when an investigation showed they did something in violation of the attendee Code of Conduct, upon review and approval by the Black Hat NOC leadership.
Cisco Secure provided all the domain name service (DNS) requests on the Black Hat network through Umbrella, whenever attendees wanted to connect to a website. If there is a specific DNS attack that threatened the conference, we supported Black Hat in blocking it to protect the network. However, by default, we allow and monitor DNS requests to malware, command and control, phishing, crypto mining, and other dangerous domains, which would be blocked in a production environment. That balance of allowing cybersecurity training and demos to occur, but ready to block when needed.
In addition to the Meraki networking gear, Cisco Secure also shipped an Umbrella DNS virtual appliance to Black Hat USA, for internal network visibility with redundancy. The Intel NUC containing the virtual appliance also contained the bridge to the NetWitness on-premises SIEM, custom developed by Ian Redden.
We also deployed the following cloud-based security software:
We analyzed files that were downloaded on the network, checking them for malicious behavior. When malware is downloaded, we confirm it is for a training, briefing or demonstration, and not the start of an attack on attendees.
During an investigation, we used SecureX to visualize the threat intelligence and related artifacts, correlating data. In the example below, an attacker was attempting remote code execution on the Registration Servers, alerted by the Palo Alto team, investigated by the NOC threat hunters, and blocked by order of the NOC leadership upon the results of the investigation.

Continued Integrations from past Black Hat events
New Integrations Created at Black Hat USA 2022
The NOC partners, especially NetWitness and Palo Alto Networks, were so collaborative and we left Vegas with more ideas for future integration development
Creating Custom Meraki Dashboard Tiles for SecureX, by Matt Vander Horst
One of the biggest benefits of Cisco SecureX is its open architecture. Anyone can build integrations for SecureX if they can develop an API with the right endpoints that speak the right language. In the case of SecureX, the language is the Cisco Threat Intelligence Model (CTIM). As mentioned above, Cisco Meraki powered Black Hat USA 2022 by providing wired and wireless networking for the entire conference. This meant a lot of equipment and users to keep track of. To avoid having to switch between two different dashboards in the NOC, we decided to build a SecureX integration that would provide Meraki dashboard tiles directly into our single pane of glass: SecureX.
Building an integration for SecureX is simple: decide what functionality you want your integration to offer, build an internet-accessible API that offers those functions, and then add the integration to SecureX. At Black Hat, our Meraki integration supported two capabilities: health and dashboard. Here’s a summary of those capabilities and the API endpoints they expect:
| Capability | Description | API Endpoints |
| Health | Enables SecureX to make sure the module is reachable and working properly. | /health |
| Dashboard | Provides a list of available dashboard tiles and, after a tile is added to a dashboard, the tile data itself. | /tiles
/tile-data |
With our capabilities decided, we moved on to building the API for SecureX to talk to. SecureX doesn’t care how you build this API if it has the expected endpoints and speaks the right language. You could build a SecureX-compatible API directly into your product, as a serverless Amazon Web Services (AWS) Lambda, as a Python script with Django, and so on. To enable rapid development at Black Hat, we chose to build our integration API on an existing Ubuntu server in AWS running Apache and PHP.
After building the API framework on our AWS server, we had to decide which dashboard tiles to offer. Here’s what we ended up supporting:
| Tile Name | Description |
| Top Applications | Shows the top 10 applications by flow count |
| Client Statistics | Shows a summary of clients |
| Top SSIDs by Usage in GB | Shows the top 10 SSIDs by data usage in GB |
| Access Point Status | Shows a summary of access points |
Finally, once the API was up and running, we could add the integration to SecureX. To do this, you need to create a module definition and then push it to SecureX using its IROH-INT API. After the module is created, it appears in the Available Integration Modules section of SecureX and can be added. Here’s what our module looked like after being added to the Black Hat SecureX instance:
After adding our new tiles to the SecureX dashboard, SecureX would ask our API for data. The API we built would fetch the data from Meraki’s APIs, format the data from Meraki for SecureX, and then return the formatted data. Here’s the result:
These dashboard tiles gave us useful insights into what was going on in the Meraki network environment alongside our existing dashboard tiles for other products such as Cisco Secure Endpoint, Cisco Umbrella, Cisco Secure Malware Analytics, and so on.

Talos Threat Hunting, by Jerzy ‘Yuri’ Kramarz and Michael Kelly
Black Hat USA 2022 was our first fully supported event, where we deployed an onsite threat hunting team from Talos Incident Response (TIR). Our colleagues and friends from various business units, connected by SecureX integration, granted us access to all the underlying consoles and API points to support the threat hunting efforts enhanced by Talos Intelligence.
The threat hunting team focused on answering three key hypothesis-driven questions and matched that with data modelling across all of the different technology stacks deployed in Black Hat NOC:
To answer the above hypothesis, our analysis started with understanding of how the network architecture is laid out and what kind of data access is granted to NOC. We quickly realized that our critical partners are key to extending visibility beyond Cisco deployed technologies. Great many thanks go to our friends from NetWitness and Palo Alto Networks for sharing full access to their technologies, to ensure that hunting did not stop on just Cisco kit and contextual intelligence could be gathered across different security products.
Daily threat hunt started with gathering data from Meraki API to identify IP and DNS level requests leaving the devices connected to wireless access points across entire conference. Although Meraki does not directly filter the traffic, we wanted to find signs of malicious activity such as DNS exfiltration attempts or connections to known and malicious domains which were not part of the class teaching. Given the level of access, we were then able to investigate network traffic capture associated with suspicious connections and check for suspected Command and Control (C2) points (there were a few from different threat actors!) or attempts to connect back to malicious DNS or Fast Flux domains which indicated that some of the attendee devices were indeed compromised with malware.
That said, this is to be expected given hostility of the network we were researching and the fact that classroom environments have users who can bring their own devices for hands-on labs. SecureX allowed us to quickly plot this internally to find specific hosts which were connecting and talking with malicious endpoints while also showing a number of additional datapoints which were useful for the investigation and hunting. Below is one such investigation, using SecureX threat response.
While looking at internal traffic, we have also found and plotted quite a few different port-scans running across the internal network. While not stopping these, it was interesting to see different tries and attempts by students to find ports and devices across networks. Good thing that network isolation was in place to prevent that! We blurred out the IP and MAC addresses in the image below.
Here is another example of really nice port scan clusters that were running across both internal and external networks we have found. This time it was the case of multiple hosts scanning each other and looking to discovery ports locally and across many of the Internet-based systems. All of that was part of the class but we had to verify that as it looked quite suspicious from the outset. Again, blurred picture for anonymity.
In a few instances, we also identified remarkably interesting clear-text LDAP traffic leaving the environment and giving a clear indicator of which organization the specific device belonged to simply because of the domain name which was requested in the cleartext. It was quite interesting to see that in 2022, we still have a lot of devices talking clear text protocols such as POP3, LDAP, HTTP or FTP, which are easy to subvert via Man-In-The-Middle type of attacks and can easily disclose the content of important messages such as email or server credentials. Below is an example of the plain text email attachments, visible in NetWitness and Cisco Secure Malware Analytics.
In terms of the external attacks, Log4J exploitation attempts were pretty much a daily occurrence on the infrastructure and applications used for attendee registration along with other typical web-based attacks such as SQL injections or path traversals. Overall, we saw a good number of port scans, floods, probes and all kind of web application exploitation attempts showing up daily, at various peak hours. Fortunately, all of them were successfully identified for context (is this part of a training class or demonstration) and contained (if appropriate) before causing any harm to external systems. Given the fact that we could intercept boundary traffic and investigate specific PCAP dumps, we used all these attacks to identify various command-and-control servers for which we also hunted internally to ensure that no internal system is compromised.
The final piece of the puzzle we looked to address, while threat hunting during Black Hat 2022, was automation to discover interesting investigation avenues. Both of us investigated a possibility of threat hunting using Jupyter playbooks to find outliers that warrant a closer look. We have created and developed a set of scripts which would gather the data from API endpoints and create a data frames which could be modeled for further analysis. This allowed us to quickly gather and filter out systems and connections which were not that interesting. Then, focus on specific hosts we should be checking across different technology stacks such as NetWitness and Palo Alto.
Unmistaken Identity, by Ben Greenbaum
An unusual aspect of the Black Hat NOC and associated security operations activities is that this is an intentionally hostile network. People come to learn new tricks and to conduct what would in any other circumstance be viewed rightfully as malicious, unwanted behavior. So, determining whether this is “acceptable” or “unacceptable” malicious behavior is an added step. Additionally, this is a heavily BYOD environment and while we do not want attendees attacking each other, or our infrastructure, there is a certain amount of suspicious or indicative behavior we may need to overlook to focus on higher priority alerts.
In short, there are broadly speaking 3 levels of security event at Black Hat:
When Umbrella alerted us (via a SecureX orchestration Webex workflow) of DNS requests for a domain involved in “Illegal Activity” it was reminiscent of an event at a previous conference where an attendee was caught using the conference network to download forged vaccination documents.
Using the Cisco Secure Malware Analytics platform’s phishing investigation tools, I loaded and explored the subject domain and found it to be a tool that generates and provides pseudo-randomized fake identities, customizable in various ways to match on demographics. Certainly, something that could be used for nefarious purposes, but is not illegal in and of itself. Physical security and access control is, however, also important at Black Hat, and if this activity was part of an effort to undermine that, then this was still a concern.
This is, however, also the kind of thing that gets taught at Black Hat…
Using the reported internal host IP from Umbrella, Meraki’s connection records, and the Meraki access point map, we were able to narrow the activity down to a specific classroom. Looking up what was being taught in that room, we were able to confirm that the activity was related to the course’s subject matter
Network owners and administrators, especially businesses, typically don’t want their network to be used for crimes. However, here at Black Hat what some would consider “crimes” is just “the curriculum”. This adds a layer of complexity to securing and protecting not just Black Hat, but also Black Hat attendees. In security operations, not every investigation leads to a smoking gun. At Black Hat, even when it does, you may find that the smoking gun was fired in a safe manner at an approved target range. Having the right tools on hand can help you make these determinations quickly and free you up to investigate the next potential threat.
25 Years of Black Hat – Musings from the show (and some DNS stats), by Alejo Calaoagan
Back in Singapore, I wrote about cloud app usage and the potential threat landscape surrounding them. My original plan at Black Hat USA was to dig deeper into this vector to see what interesting tidbits I could find on our attendee network. However, given that this was the 25th anniversary of Black Hat (and my 14th in total between Vegas, Singapore, and London), I’ve decided to pivot to talk about the show itself.
I think it’s safe to say, after two difficult pandemic years, Black Hat is back. Maybe it’s the fact that almost everyone has caught COVID by now (or that a lot of people just stopped caring). I caught it myself at RSA this year back in June, the first of consecutive summer super spread events (Cisco Live Vegas was the following week). Both of those shows were in the 15-18k attendee range, well below their pre-pandemic numbers. Black Hat USA 2022 was estimated at 27,000 attendees.
If I remember correctly, 2019 was in the 25-30K range. Last year in Vegas, there were ~3,000 people at the event, tops. 2021 in London, was even lower…it felt like there were less than 1,000 attendees. Things certainly picked up in Singapore (2-3k attendees), though that event doesn’t typically see attendee numbers as high as the other locations. All in all, while the pandemic certainly isn’t over, Las Vegas gave glimpses of what things were like before the “Rona” took over our lives.
The show floor was certainly back to the norm, with swag flying off the countertops and lines for Nike sneaker and Lego giveaways wrapping around different booths. The smiles on people’s faces as they pitched, sold, hustled, and educated the masses reminded me how much I missed this level of engagement. RSA gave me this feeling as well, before COVID sidelined me midway through the show anyway.
Not everything was quite the same. The Black Hat party scene certainly is not what it used to be. There was no Rapid 7 rager this year or last, or a happy hour event thrown by a security company you’ve never heard of at every bar you walk by on the strip. There were still some good networking events here and there, and there were some awesomely random Vanilla Ice, Sugar Ray, and Smashmouth shows. For those of you familiar with Jeremiah Grossman’s annual Black Hat BJJ throwdown, that’s still, thankfully, a thing. Hopefully, in the coming years, some of that old awesomeness returns….
Enough reminiscing, here are our DNS numbers from the show:
From a sheer traffic perspective, this was the busiest Black Hat ever, with over 50 million DNS requests made…
Digging into these numbers, Umbrella observed over 1.3 million security events, including various types of malware across the attendee network. Our threat hunting team was busy all week!
We’ve also seen an increase in app usage at Black Hat:
In a real-world production environment, Umbrella can block unapproved or high-risk apps via DNS.
The increases in DNS traffic volume and Cloud App usage obviously mirrors Black Hat’s return to the center stage of security conferences, following two years of pandemic uncertainty. I’m hopeful that things will continue to trend in a positive direction leading up to London and, hopefully, we’ll see you all there.

“Congratulations, you’re a winner!”
“Did you know this public figure is trying to make your life worse? Click here for what they don’t want you to know.”
“Save thousands today with just one click!”
Spam and bot accounts on social media are everywhere. You’ve likely encountered messages like these that attempt to get you to click on links or to stir your emotions in a frenzy. While bot accounts are usually more of an annoyance than anything, when they’re allowed to run rampant, they can quickly become dangerous to your personally identifiable information (PII) and create an emotionally charged mob mentality.
Here’s what you should know about bot accounts, including how to steer clear of menacing ones, plus a reminder to watch what you share on (and with) social media sites.
Bot accounts are software-automated accounts that try to blend in and act like a real user. They post updates and follow other users, though there isn’t a real person behind the account. A spam account is a type of bot account that attempts to gain financially from its automated posts. Everyday people should be wary of social media bot accounts because they can be used to disseminate false information or phishing scams.
One whistleblower of a social media giant recently divulged that the platform isn’t prioritizing deactivating bot accounts.1 This apathy sparks concerns about the company’s commitment to the security of its users. In the whistleblower’s same report, he stated that the social media site isn’t taking the necessary steps to protect itself from potential inside threats and it had fallen victim to at least 20 breaches in 2020 without reporting the incidents to the proper authorities.
Some bot accounts aren’t malicious (merely an annoying tactic by companies to spread the word about their business), but it’s best to give all of them a wide berth and never click on any links in their posts. Those links could direct to unsecured outside sites laden with malware or drop you in the middle of a phishing scheme.
You can often spot a malicious bot account by the tone of its messages. They’ll often try to inspire intense emotions, such as excitement, sadness, or rage, and attempt to get users to act or share the post. Do not engage with them, not even to argue their points. When you engage or share these posts with your network, it spreads false information and could dangerously manipulate public opinion.2
Here are a few ways you can take your cybersecurity into your own hands when you can’t be sure that social media sites are looking out for the safety of users’ information:

We’ve all heard about the Metaverse. And there’s no doubt it has certainly captured the attention of the world’s biggest companies: Facebook has changed its name to Meta, Hyundai has partnered up with Roblox to offer virtual test drives, Nike has bought a virtual shoe company and Coca-Cola is selling NFT’s there too. (Non-Fungible Tokens – think digital assets).
But if you are confused about exactly what this all means and most importantly, what the metaverse actually is, then you are not alone. I’m putting together a 2-part series for parents that will help us get a handle on exactly what this new digital frontier promises and what we need to know to keep our kids safe. It will also ensure we don’t feel like dinosaurs! So, let’s get started.
I think the best way of describing the Metaverse is that it’s a network of online 3D virtual worlds that mimic the real world. Once users have chosen their digital avatar, they can meet people, play games, do business, design fashion items, buy real estate, attend events, earn money, rear a pet – in fact, almost anything they can do in the ‘real’ world! And of course, all transactions are via cryptocurrencies.
If you are an avid Science Fiction reader, then you may have already come across the term in the 1992 novel ‘Snow Crash’ by Neal Stephenson. In the book, Stephenson envisions a virtual reality-based evolution of the internet in which his characters use digital avatars of themselves to explore the online world. Sounds eerily familiar, doesn’t it?
Still confused? Check out either the book or Steven Spielberg’s movie adaption of Ernest Cline’s Ready Player One. Set in 2045, the book tells the story of people living in a war-ravaged world on the brink of collapse who turn to OASIS, a massively multiplayer online simulation game that has its own virtual world and currency. In the OASIS, they engage with each other, shop, play games and be transported to different locations.
The best and most immersive way to access the metaverse is using a Virtual Reality (VR) headset and your internet connection, of course. VR headsets completely take over users’ vision and replace the outside world with a virtual one. Now, this maybe a game or a movie but VR headsets have their own set of apps which once downloaded, allows users to meditate, learn piano, work out at the gym or even attend a live concert in the metaverse!
Now access to the Metaverse is not just limited to those who own expensive headsets. Anyone with a computer or a smartphone (that is internet connected) can also have a metaverse experience. Of course, it won’t be as intense or immersive as the VR headset experience but it’s still a commonly used route to access the metaverse. Some of these ‘worlds’ suggest users can access their world using smartphones however experienced users don’t think this is a good idea as phones don’t have the necessary computational power to explore the metaverse properly.
As some of the most popular metaverse worlds can be accessed using your computer, why not check out Decentraland, The Sandbox, Somnium or even Second Life. In most of these worlds, users don’t have to create an account or spend money to start exploring however if you want the full experience then you’ll need to do so.
Entering the metaverse doesn’t cost anything, just like going on the internet doesn’t cost anything – apart from your internet connection and hardware, of course! And don’t forget that if you want a truly immersive 3D experience, then you might want to consider investing in a VR headset.
But, if you do want to access some of the features of the metaverse and invest in some virtual real estate or perhaps buy yourself a Gucci handbag, then you will need to put your hand into your virtual pocket and spend some of your virtual dollars. But the currency you will need depends entirely on the metaverse you are in.
Decentraland’s currency MANA is considered to be the most commonly used currency in the metaverse and also one of the best to invest in, according to some experts. MANA can be used to buy land, purchase avatars, names, wearables, and other items in the Decentraland marketplace.
The Sandbox has a different currency, SAND, which is also used to buy items from The Sandbox marketplace. This is the second most popular currency however be prepared to buy the currency of the world you choose to spend your time in.
Now, I totally appreciate that the whole concept of the Metaverse is a lot to get your head around. But if you have a tribe of kids, then chances are they are going to want to be part of it so don’t put it in the too-hard basket. Take some time to get your head around it: do some more reading, talk to your friends about it and check out some of the metaverses that you can access from your PC. Nothing beats experiencing it for yourself!
In Part 2, I will be sharing my top tips and strategies to help us, parents, successfully guide our kids through the challenges and risks of the metaverse. So watch out for that.
Till, next time – keep researching!

Microleaves, a ten-year-old proxy service that lets customers route their web traffic through millions of Microsoft Windows computers, recently fixed a vulnerability in their website that exposed their entire user database. Microleaves claims its proxy software is installed with user consent, but data exposed in the breach shows the service has a lengthy history of being supplied with new proxies by affiliates incentivized to distribute the software any which way they can — such as by secretly bundling it with other titles.
The Microleaves proxy service, which is in the process of being rebranded to Shifter[.[io.
Launched in 2013, Microleaves is a service that allows customers to route their Internet traffic through PCs in virtually any country or city around the globe. Microleaves works by changing each customer’s Internet Protocol (IP) address every five to ten minutes.
The service, which accepts PayPal, Bitcoin and all major credit cards, is aimed primarily at enterprises engaged in repetitive, automated activity that often results in an IP address being temporarily blocked — such as data scraping, or mass-creating new accounts at some service online.
In response to a report about the data exposure from KrebsOnSecurity, Microleaves said it was grateful for being notified about a “very serious issue regarding our customer information.”
Abhishek Gupta is the PR and marketing manager for Microleaves, which he said in the process of being rebranded to “Shifter.io.” Gupta said the report qualified as a “medium” severity security issue in Shifter’s brand new bug bounty program (the site makes no mention of a bug bounty), which he said offers up to $2,000 for reporting data exposure issues like the one they just fixed. KrebsOnSecurity declined the offer and requested that Shifter donate the amount to the Electronic Frontier Foundation (EFF), a digital rights group.
From its inception nearly a decade ago, Microleaves has claimed to lease between 20-30 million IPs via its service at any time. Riley Kilmer, co-founder of the proxy-tracking service Spur.us, said that 20-30 million number might be accurate for Shifter if measured across a six-month time frame. Currently, Spur is tracking roughly a quarter-million proxies associated with Microleaves/Shifter each day, with a high rate of churn in IPs.
Early on, this rather large volume of IP addresses led many to speculate that Microleaves was just a botnet which was being resold as a commercial proxy service.
Proxy traffic related to top Microleaves users, as exposed by the website’s API.
The very first discussion thread started by the new user Microleaves on the forum BlackHatWorld in 2013 sought forum members who could help test and grow the proxy network. At the time, the Microleaves user said their proxy network had 150,000 IPs globally, and was growing quickly.
One of BlackHatWorld’s moderators asked the administrator of the forum to review the Microleaves post.
“User states has 150k proxies,” the forum skeptic wrote. “No seller on BHW has 150k working daily proxies none of us do. Which hints at a possible BOTNET. That’s the only way you will get 150k.”
Microleaves has long been classified by antivirus companies as adware or as a “potentially unwanted program” (PUP), the euphemism that antivirus companies use to describe executable files that get installed with ambiguous consent at best, and are often part of a bundle of software tied to some “free” download. Security vendor Kaspersky flags the Microleaves family of software as a trojan horse program that commandeers the user’s Internet connection as a proxy without notifying the user.
“While working, these Trojans pose as Microsoft Windows Update,” Kaspersky wrote.
In a February 2014 post to BlackHatWorld, Microleaves announced that its sister service — reverseproxies[.]com — was now offering an “Auto CAPTCHA Solving Service,” which automates the solving of those squiggly and sometimes frustrating puzzles that many websites use to distinguish bots from real visitors. The CAPTCHA service was offered as an add-on to the Microleaves proxy service, and ranged in price from $20 for a 2-day trial to $320 for solving up to 80 captchas simultaneously.
“We break normal Recaptcha with 60-90% success rate, recaptcha with blobs 30% success, and 500+ other captcha,” Microleaves wrote. “As you know all success rate on recaptcha depends very much on good proxies that are fresh and not spammed!”
The exposed Microleaves user database shows that the first user created on the service — username “admin” — used the email address alex.iulian@aol.com. A search on that email address in Constella Intelligence, a service that tracks breached data, reveals it was used to create an account at the link shortening service bit.ly under the name Alexandru Florea, and the username “Acidut.” [Full disclosure: Constella is currently an advertiser on this website].
According to the cyber intelligence company Intel 471, a user named Acidut with the email address iulyan87_4u@gmail.com had an active presence on almost a dozen shadowy money-making and cybercrime forums from 2010 to 2017, including BlackHatWorld, Carder[.]pro, Hackforums, OpenSC, and CPAElites.
The user Microleaves (later “Shifter.io”) advertised on BlackHatWorld the sale of 31 million residential IPs for use as proxies, in late 2013. The same account continues to sell subscriptions to Shifter.io.
In a 2011 post on Hackforums, Acidut said they were building a botnet using an “exploit kit,” a set of browser exploits made to be stitched into hacked websites and foist malware on visitors. Acidut claimed their exploit kit was generating 3,000 to 5,000 new bots each day. OpenSC was hacked at one point, and its private messages show Acidut purchased a license from Exmanoize, the handle used by the creator of the Eleonore Exploit Kit.
By November 2013, Acidut was advertising the sale of “26 million SOCKS residential proxies.” In a March 2016 post to CPAElites, Acidut said they had a worthwhile offer for people involved in pay-per-install or “PPI” schemes, which match criminal gangs who pay for malware installs with enterprising hackers looking to sell access to compromised PCs and websites.
Because pay-per-install affiliate schemes rarely impose restrictions on how the software can be installed, such programs can be appealing for cybercriminals who already control large collections of hacked machines and/or compromised websites. Indeed, Acidut went a step further, adding that their program could be quietly and invisibly nested inside of other programs.
“For those of you who are doing PPI I have a global offer that you can bundle to your installer,” Acidut wrote. “I am looking for many installs for an app that will generate website visits. The installer has a silence version which you can use inside your installer. I am looking to buy as many daily installs as possible worldwide, except China.”
Asked about the source of their proxies in 2014, the Microleaves user responded that it was “something related to a PPI network. I can’t say more and I won’t get into details.”
Acidut authored a similar message on the forum BlackHatWorld in 2013, where they encouraged users to contact them on Skype at the username “nevo.julian.” That same Skype contact address was listed prominently on the Microleaves homepage up until about a week ago when KrebsOnSecurity first reached out to the company.
There is a Facebook profile for an Alexandru Iulian Florea from Constanta, Romania, whose username on the social media network is Acidut. Prior to KrebsOnSecurity alerting Shifter of its data breach, the Acidut profile page associated Florea with the websites microleaves.com, shrooms.io, leftclick[.]io, and online[.]io. Mr. Florea did not respond to multiple requests for comment, and his Facebook page no longer mentions these domains.
Leftclick and online[.]io emerged as subsidiaries of Microleaves between 2017 and 2018. According to a help wanted ad posted in 2018 for a developer position at online[.]io, the company’s services were brazenly pitched to investors as “a cybersecurity and privacy tool kit, offering extensive protection using advanced adblocking, anti-tracking systems, malware protection, and revolutionary VPN access based on residential IPs.”
A teaser from Irish Tech News.
“Online[.]io is developing the first fully decentralized peer-to-peer networking technology and revolutionizing the browsing experience by making it faster, ad free, more reliable, secure and non-trackable, thus freeing the Internet from annoying ads, malware, and trackers,” reads the rest of that help wanted ad.
Microleaves CEO Alexandru Florea gave an “interview” to the website Irishtechnews.ie in 2018, in which he explained how Online[.]io (OIO) was going to upend the online advertising and security industries with its initial coin offering (ICO). The word interview is in air quotes because the following statements by Florea deserved some serious pushback by the interviewer.
“Online[.]io solution, developed using the Ethereum blockchain, aims at disrupting the digital advertising market valued at more than $1 trillion USD,” Alexandru enthused. “By staking OIO tokens and implementing our solution, the website operators will be able to access a new non-invasive revenue stream, which capitalizes on time spent by users online.”
“At the same time, internet users who stake OIO tokens will have the opportunity to monetize on the time spent online by themselves and their peers on the World Wide Web,” he continued. “The time spent by users online will lead to ICE tokens being mined, which in turn can be used in the dedicated merchant system or traded on exchanges and consequently changed to fiat.”
Translation: If you install our proxy bot/CAPTCHA-solver/ad software on your computer — or as an exploit kit on your website — we’ll make millions hijacking ads and you will be rewarded with heaps of soon-to-be-worthless shitcoin. Oh, and all your security woes will disappear, too.
It’s unclear how many Internet users and websites willingly agreed to get bombarded with Online[.]io’s annoying ads and search hijackers — and to have their PC turned into a proxy or CAPTCHA-solving zombie for others. But that is exactly what multiple security companies said happened when users encountered online[.]io, which operated using the Microsoft Windows process name of “online-guardian.exe.”
Incredibly, Crunchbase says Online[.]io raised $6 million in funding for an initial coin offering in 2018, based on the plainly ludicrous claims made above. Since then, however, online[.]io seems to have gone…offline, for good.
Until this week, Shifter.io’s website also exposed information about its customer base and most active users, as well as how much money each client has paid over the lifetime of their subscription. The data indicates Shifter has earned more than $11.7 million in direct payments, although it’s unclear how far back in time those payment records go, or how complete they are.
The bulk of Shifter customers who spent more than $100,000 at the proxy service appear to be digital advertising companies, including some located in the United States. None of the several Shifter customers approached by KrebsOnSecurity agreed to be interviewed.
Shifter’s Gupta said he’d been with the company for three years, since the new owner took over the company and made the rebrand to Shifter.
“The company has been on the market for a long time, but operated under a different brand called Microleaves, until new ownership and management took over the company started a reorganization process that is still on-going,” Gupta said. “We are fully transparent. Mostly [our customers] work in the data scraping niche, this is why we actually developed more products in this zone and made a big shift towards APIs and integrated solutions in the past year.”
Ah yes, the same APIs and integrated solutions that were found exposed to the Internet and leaking all of Shifter’s customer information.
Gupta said the original founder of Microleaves was a man from India, who later sold the business to Florea. According to Gupta, the Romanian entrepreneur had multiple issues in trying to run the company, and then sold it three years ago to the current owner — Super Tech Ventures, a private equity company based in Taiwan.
“Our CEO is Wang Wei, he has been with the company since 3 years ago,” Gupta said. “Mr. Florea left the company two years ago after ending this transition period.”
Google and other search engines seem to know nothing about a Super Tech Ventures based in Taiwan. Incredibly, Shifter’s own PR person claimed that he, too, was in the dark on this subject.
“I would love to help, but I really don’t know much about the mother company,” Gupta said, essentially walking back his “fully transparent” statement. “I know they are a branch of the bigger group of asian investment firms focused on private equity in multiple industries.”
Adware and proxy software are often bundled together with “free” software utilities online, or with popular software titles that have been pirated and quietly fused with installers tied to various PPI affiliate schemes.
But just as often, these intrusive programs will include some type of notice — even if installed as part of a software bundle — that many users simply do not read and click “Next” to get on with installing whatever software they’re seeking to use. In these cases, selecting the “basic” or “default” settings while installing usually hides any per-program installation prompts, and assumes you agree to all of the bundled programs being installed. It’s always best to opt for the “custom” installation mode, which can give you a better idea of what is actually being installed, and can let you control certain aspects of the installation.
Either way, it’s best to start with the assumption that if a software or service online is “free,” that there is likely some component involved that allows the provider of that service to monetize your activity. As KrebsOnSecurity noted at the conclusion of last week’s story on a China-based proxy service called 911, the rule of thumb for transacting online is that if you’re not the paying customer, then you and/or your devices are probably the product that’s being sold to others.

Sextortion is something no parent wants to think could happen to their child, nor a topic most of us would ever imagine we’d need to discuss in our homes. However, according to the latest FBI reports, sextortion is a digital threat to children that, woefully, is on the rise.
According to the FBI, there has been a considerable increase lately in sextortion cases involving children and teens being coerced by adults online.
A sextortion scenario can emerge in several ways. Most often, it occurs when an adult (posing as a peer) engages in casual conversation with an underage child, gains their trust through online conversation, then pressures or threatens the child into sharing sexual photos or videos of themselves.
In some cases, the initial contact with the criminal will be a threat. The person may claim to already have a revealing picture or video of a child that they threaten to share if the victim does not send more pictures.
According to the FBI, this crime more often starts when young people believe they are communicating with someone their age who is interested in a relationship or with someone who is offering something of value. This catfish (false profile) relationship usually involves the predator using gifts, money, flattery, lies, or other methods to get a young person to produce an image.
These dangerous conversations can be initiated through text, a social or chat app, a gaming site, or any number of digital connection points.
After a criminal successfully obtains a photo or video from their victim, the threats can escalate to promises to publish the content or even hurt the child if they don’t send more. This emotionally harrowing situation can ignite shame, fear, and confusion in children who may be too embarrassed to ask for help or report the abuse.
While these criminals rarely request to meet their victims face-to-face, the emotional and physical impact of sextortion can be devastating to a child. According to the FBI, some victims report abusers who become vicious with non-stop harassment and threats. Victims can feel scared, alone, embarrassed, and increasingly desperate. Sadly, as reported in the news, this type of crime can leave some children feeling like they have no way out of the situation.
If you are a parent or caregiver, explain to your child how sextortion can happen to anyone online and why it’s important to only connect with known friends and family. Parents: Consider boosting your device security with parental controls that filter content, report your child’s online activity, and reveal potential problems.
Some essential safety protocols kids should follow online are worthy of repeating. They are:
1) Make social accounts private, don’t share personal information, and only connect with known friends
2) Ignore and block messages from strangers
3) Keep your guard up. People can pretend to be anyone online, and photos can be altered
4) Be suspect if anyone asks you to message or text with them privately
5) Never share risky photos with anyone online—even a trusted friend
6) Tell someone immediately if someone is threatening you online.
With your child, go through their apps, social networks, chats, gaming communities, and friend groups and do some editing, defriending, and blocking. Make sure both you and your child know and trust all their online connections. Remember: Open communication and an honest relationship with your child are the most powerful tools you have to keep your child safe online.
A sextortion situation for a child can be incredibly confusing and cause them to isolate and avoid telling anyone about it. Remind and be clear with your child that they would never be in trouble for coming to you with any problem. Let them know that sextortion is a crime for the perpetrator and that they have not broken any laws by sending photos (despite what an abuser might have told them).
Victims of sextortion should go to a parent or trusted adult and tell them they need help. While doing this can feel terrifying, it’s crucial for victims to know people understand and want to help. For parents and caregivers, contact the FBI at 1-800-CALL-FBI or report the crime online at tips.fbi.gov.
While the bad actors online are out to exploit and ruin our digital spaces, it’s important to maintain a healthy perspective rather than responding with fear. Remind your kids that there’s an army of people even more dedicated than the criminals; people like the FBI who are out to stop online crime and keep the internet safe for families. Additionally, as a parent or caregiver, your commitment to helping your family stay informed, equipped, and empowered online is how we all win.

U.S. state and federal investigators are being inundated with reports from people who’ve lost hundreds of thousands or millions of dollars in connection with a complex investment scam known as “pig butchering,” wherein people are lured by flirtatious strangers online into investing in cryptocurrency trading platforms that eventually seize any funds when victims try to cash out.
The term “pig butchering” refers to a time-tested, heavily scripted, and human-intensive process of using fake profiles on dating apps and social media to lure people into investing in elaborate scams. In a more visceral sense, pig butchering means fattening up a prey before the slaughter.
“The fraud is named for the way scammers feed their victims with promises of romance and riches before cutting them off and taking all their money,” the Federal Bureau of Investigation (FBI) warned in April 2022. “It’s run by a fraud ring of cryptocurrency scammers who mine dating apps and other social media for victims and the scam is becoming alarmingly popular.”
As documented in a series of investigative reports published over the past year across Asia, the people creating these phony profiles are largely men and women from China and neighboring countries who have been kidnapped and trafficked to places like Cambodia, where they are forced to scam complete strangers over the Internet — day after day.
The most prevalent pig butchering scam today involves sophisticated cryptocurrency investment platforms, where investors invariably see fantastic returns on their deposits — until they try to withdraw the funds. At that point, investors are told they owe huge tax bills. But even those who pay the phony levies never see their money again.
The come-ons for these scams are prevalent on dating sites and apps, but they also frequently start with what appears to be a wayward SMS — such as an instant message about an Uber ride that never showed. Or a reminder from a complete stranger about a planned meetup for coffee. In many ways, the content of the message is irrelevant; the initial goal to simply to get the recipient curious enough to respond in some way.
Those who respond are asked to continue the conversation via WhatsApp, where an attractive, friendly profile of the opposite gender will work through a pre-set script that is tailored to their prey’s apparent socioeconomic situation. For example, a divorced, professional female who responds to these scams will be handled with one profile type and script, while other scripts are available to groom a widower, a young professional, or a single mom.
That’s according to Erin West, deputy district attorney for Santa Clara County in Northern California. West said her office has been fielding a large number of pig butchering inquiries from her state, but also from law enforcement entities around the country that are ill-equipped to investigate such fraud.
“The people forced to perpetrate these scams have a guide and a script, where if your victim is divorced say this, or a single mom say this,” West said. “The scale of this is so massive. It’s a major problem with no easy answers, but also with victim volumes I’ve never seen before. With victims who are really losing their minds and in some cases are suicidal.”
West is a key member of REACT, a task force set up to tackle especially complex forms of cyber theft involving virtual currencies. West said the initial complaints from pig butchering victims came early this year.
“I first thought they were one-off cases, and then I realized we were getting these daily,” West said. “A lot of them are being reported to local agencies that don’t know what to do with them, so the cases languish.”
West said pig butchering victims are often quite sophisticated and educated people.
“One woman was a university professor who lost her husband to COVID, got lonely and was chatting online, and eventually ended up giving away her retirement,” West recalled of a recent case. “There are just horrifying stories that run the gamut in terms of victims, from young women early in their careers, to senior citizens and even to people working in the financial services industry.”
In some cases reported to REACT, the victims said they spent days or weeks corresponding with the phony WhatsApp persona before the conversation shifted to investing.
“They’ll say ‘Hey, this is the food I’m eating tonight’ and the picture they share will show a pretty setting with a glass of wine, where they’re showcasing an enviable lifestyle but not really mentioning anything about how they achieved that,” West said. “And then later, maybe a few hours or days into the conversation, they’ll say, ‘You know I made some money recently investing in crypto,’ kind of sliding into the topic as if this wasn’t what they were doing the whole time.”
Curious investors are directed toward elaborate and official-looking online crypto platforms that appear to have thousands of active investors. Many of these platforms include extensive study materials and tutorials on cryptocurrency investing. New users are strongly encouraged to team up with more seasoned investors on the platform, and to make only small investments that they can afford to lose.
The now-defunct homepage of xtb-market[.]com, a scam cryptocurrency platform tied to a pig butchering scheme.
“They’re able to see some value increase, and maybe even be allowed to take out that value increase so that they feel comfortable about the situation,” West said. Some investors then need little encouragement to deposit additional funds, which usually generate increasingly higher “returns.”
West said many crypto trading platforms associated with pig butchering scams appear to have been designed much like a video game, where investor hype is built around upcoming “trading opportunities” that hint at even more fantastic earnings.
“There are bonus levels and VIP levels, and they’ll build hype and a sense of frenzy into the trading,” West said. “There are definitely some psychological mechanisms at work to encourage people to invest more.”
“What’s so devastating about many of the victims is they lose that sense of who they are,” she continued. “They thought they were a savvy, sophisticated person, someone who’s sort of immune to scams. I think the large scale of the trickery and psychological manipulation being used here can’t be understated. It’s like nothing I’ve seen before.”
Courtney Nolan, a divorced mother of three daughters, says she lost more than $5 million to a pig butchering scam. Nolan lives in St. Louis and has a background in investment finance, but only started investing in cryptocurrencies in the past year.
Nolan’s case may be especially bad because she was already interested in crypto investing when the scammer reached out. At the time, Bitcoin was trading at or near all-time highs of nearly $68,000 per coin.
Nolan said her nightmare began in late 2021 with a Twitter direct message from someone who was following many of the same cryptocurrency influencers she followed. Her fellow crypto enthusiast then suggested they continue their discussion on WhatsApp. After much back and forth about his trading strategies, her new friend agreed to mentor her on how to make reliable profits using the crypto trading platform xtb.com.
“I had dabbled in leveraged trading before, but his mentor program gave me over 100 pages of study materials and agreed to walk me through their investment strategies over the course of a year,” Nolan told KrebsOnSecurity.
Nolan’s mentor had her create an account website xtb-market[.]com, which was made to be confusingly similar to XTB’s official platform. The site promoted several different investment packages, including a “starter plan” that involves a $5,250 up-front investment and promises more than 15 percent return across four separate trading bursts.
Platinum plans on xtb-market promised a whopping 45 percent ROI, with a minimum investment of $265,000. The site also offered a generous seven percent commission for referrals, which encouraged new investors to recruit others.
The now-defunct xtb-market[.]com.
While chatting via WhatsApp, Nolan and her mentor would trade side by side in xtb-market, initially with small investments ranging from $500 to $5,000. When those generated hefty returns, Nolan made bigger deposits. On several occasions she was able to withdraw amounts ranging from $10,000 to $30,000.
But after investing more than $4.5 million of her own money over nearly four months, Nolan found her account was suddenly frozen. She was then issued a tax statement saying she owed nearly $500,000 in taxes before she could reactivate her account or access her funds.
Nolan said it seems obvious in hindsight that she should never have paid the tax bill. Because xtb-market and her mentor cut all communications with her after that, and the entire website disappeared just a few weeks later.
Justin Maile, an investigation partner manager at Chainalysis, told Vice News that the tax portion of the pig butchering scam relies on the “sunk costs fallacy,” when people are reluctant to abandon a failing strategy or course of action because they have already invested heavily in it.
“Once the victim starts getting skeptical or tries to withdraw their funds, they are often told that they have to pay tax on the gains before funds can be unlocked,” Maile told Vice News. “The scammers will try to get any last payments out of the victims by exploiting the sunk cost fallacy and dangling huge profits in front of them.”
Vice recently published an in-depth report on pig butchering’s link to organized crime gangs in Asia that lure young job seekers with the promise of customer service jobs in call centers. Instead, those who show up at the appointed place and time are taken on long car rides and/or forced hikes across the borders into Cambodia, where they are pressed into indentured servitude.
Vice found many of the people forced to work in pig-butchering scams are being held in Chinese-owned casinos operating in Cambodia. Many of those casinos were newly built when the Covid pandemic hit. As the new casinos and hotels sat empty, organized crime groups saw an opportunity to use these facilities to generate huge income streams, and many foreign travelers stranded in neighboring countries were eventually trafficked to these scam centers.
Vice reports:
“While figures on the number of people in scam centers in Cambodia is unknown, best estimates pieced together from various sources point to the tens of thousands across scam centers in Sihanoukville, Phnom Penh, and sites in border regions Poipet and Bavet. In April, Thailand’s assistant national police commissioner said 800 Thai citizens had been rescued from scam centers in Cambodia in recent months, with a further 1,000 citizens still trapped across the country. One Vietnamese worker estimated 300 of his compatriots were held on just one floor in a tall office block hosting scam operations.”
“…within Victory Paradise Resort alone there were 7,000 people, the majority from mainland China, but also Indonesians, Singaporeans and Filipinos. According to the Khmer Times, one 10-building complex of high-rises in Sihanoukville, known as The China Project, holds between 8,000 to 10,000 people participating in various scams—a workforce that would generate profits around the $1 billion mark each year at $300 per worker per day.”
REACTs’ West said while there are a large number of pig butchering victims reporting their victimization to the FBI, very few are receiving anything more than instructions about filing a complaint with the FBI’s Internet Crime Complaint Center (IC3), which keeps track of cybercrime losses and victims.
“There’s a huge gap in victims that are seeing any kind of service at all, where they’re reporting to the FBI but not being able to talk to anyone,” she said. “They’re filling out the IC3 form and never hearing back. It sort of feels like the federal government is ignoring this, so people are going to local agencies, which are sending these victims our way.”
For many younger victims of pig butchering, even losses of a few thousand dollars can be financially devastating. KrebsOnSecurity recently heard from two different readers who said they were in their 20s and lost more than $40,000 each when the investment platforms they were trading on vanished with their money.
The FBI can often bundle numerous IC3 complaints involving the same assailants and victims into a single case for federal prosecutors to pursue the guilty, and/or try to recapture what was stolen. In general, however, victims of crypto crimes rarely see that money again, or if they do it can take many years.
“The next piece is what can we actually do with these cases,” West said. “We used to frame success as getting bad people behind bars, but these cases leave us as law enforcement with not a lot of opportunity there.”
West said the good news is U.S. authorities are seeing some success in freezing cryptocurrency wallets suspected of being tied to large-scale cybercriminal operations. Indeed, Nolan told KrebsOnSecurity that her losses were substantial enough to warrant an official investigation by the FBI, which she says has since taken steps to freeze at least some of the assets tied to xtb-market[.]com.
Likewise, West said she was recently able to freeze cryptocurrency funds stolen from some pig butchering victims, and now REACT is focusing on helping state and local authorities learn how to do the same.
“It’s important to be able to mobilize quickly and know how to freeze and seize crypto and get it back to its rightful owner,” West said. “We definitely have made seizures in cases involving pig butchering, but we haven’t gotten that back to the rightful owners yet.”
In April, the FBI warned Internet users to be on guard against pig butchering scams, which it said attracts victims with “promises of romance and riches” before duping them out of their money. The IC3 said it received more than 4,300 complaints related to crypto-romance scams, resulting in losses of more than $429 million.
Here are some common elements of a pig butchering scam:
–Dating apps: Pig-butchering attempts are common on dating apps, but they can begin with almost any type of communication, including SMS text messages.
–WhatsApp: In virtually all documented cases of pig butchering, the target is moved fairly quickly into chatting with the scammer via WhatsApp.
–No video: The scammers will come up with all kinds of excuses not to do a video call. But they will always refuse.
–Investment chit-chat: Your contact (eventually) claims to have inside knowledge about the cryptocurrency market and can help you make money.
The FBI’s tips on avoiding crypto scams:
-Never send money, trade, or invest based on the advice of someone you have only met online.
-Don’t talk about your current financial status to unknown and untrusted people.
-Don’t provide your banking information, Social Security Number, copies of your identification or passport, or any other sensitive information to anyone online or to a site you do not know is legitimate.
-If an online investment or trading site is promoting unbelievable profits, it is most likely that—unbelievable.
-Be cautious of individuals who claim to have exclusive investment opportunities and urge you to act fast.
It’s a question we get a lot from parents: “How can I keep my kids safe when they are constantly hopping between so many different apps?” We get it, there’s a lot to stay on top and all of it changes constantly. Unfortunately, that question doesn’t have a simple answer. But there are some baseline actions every parent can take to boost their child’s safety on popular apps like TikTok, Snapchat, and Instagram.
The safety equation is threefold, with every piece as important to your child’s overall safety as the next.
A report released in 2021 by Common Sense Media found that teenagers (ages 13-18) use an average of nine hours of entertainment media per day and that tweens (ages 8-12) use an average of six hours a day, not including time spent using media for school or homework. The report also found that boys spend more time on gaming devices while girls spend more time on social media and that mobile devices now account for 41% of all screen time among tweens and 46% among teens.
With those numbers increasing each year, it’s even more important to understand the different ways parents can help kids stay safe. Let’s break down a few safety basics on each app that are easy to access and use.
TikTok has some impressive safety guidelines broken down into topics parents could easily use as a springboard for some great family discussions. The guidelines and the Safety Center cover issues such as dangerous TikTok challenges and how to deal with other digital threats such as bullying, sexual content, fake news, and hateful behavior. You can increase safeguards using TikTok’s:
Every app functions differently and thus, offers different ways to boost security. Snapchat provides a helpful guide for parents and educators, including safety tips and conversation starters. You can increase safeguards using Snapchat’s:
Instagram offers parents and minor users a library of safety and mental health resources accessible via the app’s Community Tab at the bottom of its home page. You can increase safeguards using Instagram’s:
One of the most powerful safety features is you—a child’s mom, dad, or guardian. Your face-to-face, heart-to-heart connection will speak loudest in your child’s life. If you haven’t lately, ask your child what’s going on in their digital life, who their friends are, what they’ve created to share, and what’s new, hilarious, or trending. You may get some resistance now and then but don’t let that discourage you from pressing in and doing all the things that help keep them as safe as possible online.

It’s Social Media Day! How are you celebrating? Reposting your very first profile picture from a decade ago? Sharing your most-loved status update or the photo you’re most proud of? This year, consider commemorating the day by learning more about how to keep your information safe. Enjoy your favorite platform, but be on the lookout for scams, such as social engineering.
Social engineering is a cybercrime common to social media sites. It is a tactic where a cybercriminal lurks on people’s social media pages, gleaning personal information that they then use to impersonate them elsewhere.
With more than half of the global population on social media, you may think that a cybercriminal will never single you out from such a huge pool; however, it is possible.1 Luckily, you only have to make a few, easy changes to your online habits to keep your valuable private information just that: private. Check out these tips to make smart decisions and be more confident about your and your family’s online security.
Think of the types of posts you share with your dozens – or even hundreds or thousands! – of followers: updates about your life, where you live, work, or favorite travel destinations, your hobbies, pets, family members, etc. All of these details, that only you and those closest to you should know, are a valuable commodity to cybercriminals. Plus, now that social media shopping is growing in popularity, the credit card information linked to accounts is sweetening the deal for cybercriminals.
Here are a few social engineering scams that are common to social media.
People commonly create passwords based on things, places, and people that are important. Have you ever published a 20 questions-style get-to-know-me post? Those contain a lot of valuable personally identifiable information (PII). With just a few of those details about your personal life, cybercriminals can make educated guesses at your passwords, a tactic called credential stuffing. If they’re able to crack the code to one of your accounts, they’ll then input that password and login variations in several other sites, especially online banking portals, to see if they can gain entry to those too.
You’ve won! Send us your banking information and address, and you’ll receive a package in the mail or a direct deposit to your bank account!
But did you enter a drawing for a prize? Very rarely does anyone win something just by being a follower of a certain page. If you receive a message similar to the above, it’s likely a phisher trying to draw more PII and sensitive banking information out of you. Or, the message may have links within it that redirect to an untrustworthy site. If you regularly enter social media contests, keep a list and only respond to legitimate ones. Also, never give your banking information out over social media, private messages, or email.
There are plenty of valid fundraisers and petitions circulating around social media; however, there are just as many social engineering scams that dupe social media users because they inspire a strong emotion in them. For example, there have been several scams around Ukrainian donation sites. Cybercriminals often use fear, anger, or sadness to inspire people to open their wallets and share confidential banking information.
Luckily, all it takes is a few smart habits to stop social engineers in their tracks. Consider the following tips and make these small changes to your social media usage:
At this point, you’ve probably had several of your social media accounts active for over a decade. That means it’s time to do some cleaning out of your friends and followers lists. It’s best to only accept requests from people you personally know and would actually like to keep in the loop about your life. A friend and follower request from strangers could be cyber criminals in disguise. Also, consider setting your account to private so that your posts are invisible to strangers.
Social engineering hacks often bank on people acting rashly and quickly because of strong emotion, either excitement, fear, sadness, or anger. If you see a post on your newsfeed or receive a direct message that gives you a tight window to respond and asks for PII, slow down and think before acting. Double-check the destination of every link in the message by hovering over it with your cursor and checking the link preview at the bottom of your browser screen. Be careful, because some link previews include slight misspellings of legitimate websites. As a great rule of thumb, be automatically skeptical of direct messages from people you do not personally know. And if a DM from a friend seems out of the ordinary, shoot them a text to confirm they actually sent it. It could be that their social media account was hacked and a criminal is spamming their followers.
A password manager will go a long way toward ensuring you have unique, strong passwords and passphrases for every account. Not reusing passwords makes credential stuffing impossible. McAfee True Key stores all your logins and passwords and guards them with one of the strongest encryption algorithms available. All you need to do is remember your master password. It’s a great practice to also enable multifactor authentication whenever a website offers it. This makes it incredibly difficult for a cybercriminal to break into your online accounts with their educated guesses at your password.
Now that you know what to look for and the best tricks to be safe, you can feel more confident that you’re doing everything you can to protect your online accounts and private information. McAfee Protection Score can also help you take control of your online safety. This service allows you to monitor your current online safety and encourages you to take specific steps to improve it. Now you can enjoy digitally keeping in touch with your friends with peace of mind!

In part one of our Black Hat Asia 2022 NOC blog, we discussed building the network with Meraki:
In this part two, we will discuss:
SecureX: Bringing Threat Intelligence Together by Ian Redden
In addition to the Meraki networking gear, Cisco Secure also shipped two Umbrella DNS virtual appliances to Black Hat Asia, for internal network visibility with redundancy, in addition to providing:
Cisco Secure Threat Intelligence (correlated through SecureX)
Donated Partner Threat Intelligence (correlated through SecureX)
alphaMountain.ai threat intelligence
Open-Source Threat Intelligence (correlated through SecureX)
Continued Integrations from past Black Hat events
New Integrations Created at Black Hat Asia 2022
Device type spoofing event by Jonny Noble
Overview
During the conference, a NOC Partner informed us that they received an alert from May 10 concerning an endpoint client that accessed two domains that they saw as malicious:
Client details from Partner:
Based on the user agent, the partner derived that the device type was an Apple iPhone.
SecureX analysis
Umbrella Investigate analysis
Umbrella Investigate positions both domains as low risk, both registered recently in Poland, and both hosted on the same IP:
Despite the low-risk score, the nameservers have high counts of malicious associated domains:
Targeting users in ASA, UK, and Nigeria:
Meraki analysis
Based on the time of the incident, we can trace the device’s location (based on its IP address). This is thanks to the effort we invested in mapping out the exact location of all Meraki APs, which we deployed across the convention center with an overlay of the event map covering the area of the event:
Further analysis and conclusions
The device name (LAPTOP-8MLGXXXXXX) and MAC address seen (f4:XX:XX:XX:XX:XX) both matched across the partner and Meraki, so there was no question that we were analyzing the same device.
Based on the useragent captured by the partner, the device type was an Apple iPhone. However, Meraki was reporting the Device and its OS as “Intel, Android”
A quick look up for the MAC address confirmed that the OUI (organizationally unique identifier) for f42679 was Intel Malaysia, making it unlikely that this was an Apple iPhone.
The description for the training “Web Hacking Black Belt Edition” can be seen here:
https://www.blackhat.com/asia-22/training/schedule/#web-hacking-black-belt-edition–day-25388
It is highly likely that the training content included the use of tools and techniques for spoofing the visibility of useragent or device type.
There is also a high probability that the two domains observed were used as part of the training activity, rather than this being part of a live attack.
It is clear that integrating the various Cisco technologies (Meraki wireless infrastructure, SecureX, Umbrella, Investigate) used in the investigation of this incident, together with the close partnership and collaboration of our NOC partners, positioned us where we needed to be and provided us with the tools we needed to swiftly collect the data, join the dots, make conclusions, and successfully bring the incident to closure.
Self Service with SecureX Orchestration and Slack by Matt Vander Horst
Overview
Since Meraki was a new platform for much of the NOC’s staff, we wanted to make information easier to gather and enable a certain amount of self-service. Since the Black Hat NOC uses Slack for messaging, we decided to create a Slack bot that NOC staff could use to interact with the Meraki infrastructure as well as Palo Alto Panorama using the SecureX Orchestration remote appliance. When users communicate with the bot, webhooks are sent to Cisco SecureX Orchestration to do the work on the back end and send the results back to the user.
Design
Here’s how this integration works:
Workflow #1: Handle Slash Commands
Slash commands are a special type of message built into Slack that allow users to interact with a bot. When a Slack user executes a slash command, the command and its arguments are sent to SecureX Orchestration where a workflow handles the command. The table below shows a summary of the slash commands our bot supported for Black Hat Asia 2022:
Here’s a sample of a portion of the SecureX Orchestration workflow that powers the above commands:
And here’s a sample of firewall logs as returned from the “/pan_traffic_history” command:
Workflow #2: Handle Interactivity
A more advanced form of user interaction comes in the form of Slack blocks. Instead of including a command’s arguments in the command itself, you can execute the command and Slack will present you with a form to complete, like this one for the “/update_vlan” command:
These forms are much more user friendly and allow information to be pre-populated for the user. In the example above, the user can simply select the switch to configure from a drop-down list instead of having to enter its name or serial number. When the user submits one of these forms, a webhook is sent to SecureX Orchestration to execute a workflow. The workflow takes the requested action and sends back a confirmation to the user:
Conclusion
While these two workflows only scratched the surface of what can be done with SecureX Orchestration webhooks and Slack, we now have a foundation that can be easily expanded upon going forward. We can add additional commands, new forms of interactivity, and continue to enable NOC staff to get the information they need and take necessary action. The goal of orchestration is to make life simpler, whether it is by automating our interactions with technology or making those interactions easier for the user.
Future Threat Vectors to Consider – Cloud App Discovery by Alejo Calaoagan
Since 2017 (starting in Black Hat USA – Las Vegas), Cisco Umbrella has provided DNS security to the Black Hat attendee network, added layers of traffic visibility previously not seen. Our efforts have largely been successful, identifying thousands of threats over the years and mitigating them via Umbrella’s blocking capabilities when necessary. This was taken a step further at Black Hat London 2021, where we introduced our Virtual Appliances to provide source IP attribution to the devices making requests.
Here at Black Hat Asia 2022, we’ve been noodling on additional ways to provide advanced protection for future shows, and it starts with Umbrella’s Cloud Application Discovery’s feature, which identified 2,286 unique applications accessed by users on the attendee network across the four-day conference. Looking at a snapshot from a single day of the show, Umbrella captured 572,282 DNS requests from all cloud apps, with over 42,000 posing either high or very high risk.
Digging deeper into the data, we see not only the types of apps being accessed…
…but also see the apps themselves…
…and we can flag apps that look suspicious.
We also include risk downs breaks by category…
…and drill downs on each.
While this data alone won’t provide enough information to take action, including this data in analysis, something we have been doing, may provide a window into new threat vectors that may have previously gone unseen. For example, if we identify a compromised device infected with malware or a device attempting to access things on the network that are restricted, we can dig deeper into the types of cloud apps those devices are using and correlate that data with suspicious request activity, potential uncovering tools we should be blocking in the future.
I can’t say for certain how much this extra data set will help us uncover new threats, but, with Black Hat USA just around the corner, we’ll find out soon.
Using SecureX sign-on to streamline access to the Cisco Stack at Black Hat by Adi Sankar
From five years ago to now, Cisco has tremendously expanded our presence at Black Hat to include a multitude of products. Of course, sign-on was simple when it was just one product (Secure Malware Analytics) and one user to log in. When it came time to add a new technology to the stack it was added separately as a standalone product with its own method of logging in. As the number of products increased, so did the number of Cisco staff at the conference to support these products. This means sharing usernames and passwords became tedious and not to mention insecure, especially with 15 Cisco staff, plus partners, accessing the platforms.
The Cisco Secure stack at Black Hat includes SecureX, Umbrella, Malware Analytics, Secure Endpoint (iOS clarity), and Meraki. All of these technologies support using SAML SSO natively with SecureX sign-on. This means that each of our Cisco staff members can have an individual SecureX sign-on account to log into the various consoles. This results in better role-based access control, better audit logging and an overall better login experience. With SecureX sign-on we can log into all the products only having to type a password one time and approve one Cisco DUO Multi-Factor Authentication (MFA) push.
How does this magic work behind the scenes? It’s actually rather simple to configure SSO for each of the Cisco technologies, since they all support SecureX sign-on natively. First and foremost, you must set up a new SecureX org by creating a SecureX sign-on account, creating a new organization and integrating at least one Cisco technology. In this case I created a new SecureX organization for Black Hat and added the Secure Endpoint module, Umbrella Module, Meraki Systems Manager module and the Secure Malware Analytics module. Then from Administration à Users in SecureX, I sent an invite to the Cisco staffers that would be attending the conference, which contained a link to create their account and join the Blackhat SecureX organization. Next let’s take a look at the individual product configurations.
Meraki:
In the Meraki organization settings enable SecureX sign-on. Then under Organization à Administrators add a new user and specify SecureX sign-on as the authentication method. Meraki even lets you limit users to particular networks and set permission levels for those networks. Accepting the email invitation is easy since the user should already be logged into their SecureX sign-on account. Now, logging into Meraki only requires an email address and no password or additional DUO push.
Umbrella:
Under Admin à Authentication configure SecureX sign-on which requires a test login to ensure you can still login before using SSO for authentication to Umbrella. There is no need to configure MFA in Umbrella since SecureX sign-on comes with built in DUO MFA. Existing users and any new users added in Umbrella under Admin à Accounts will now be using SecureX sign-on to login to Umbrella. Logging into Umbrella is now a seamless launch from the SecureX dashboard or from the SecureX ribbon in any of the other consoles.
Secure Malware Analytics:
A Secure Malware Analytics organization admin can create new users in their Threat Grid tenant. This username is unique to Malware Analytics, but it can be connected to a SecureX sign-on account to take advantage of the seamless login flow. From the email invitation the user will create a password for their Malware Analytics user and accept the EULA. Then in the top right under My Malware Analytics Account, the user has an option to connect their SecureX sign-on account which is a one click process if already signed in with SecureX sign-on. Now when a user navigates to Malware Analytics login page, simply clicking “Login with SecureX Sign-On” will grant them access to the console.
Secure Endpoint:
The Secure Endpoint deployment at Blackhat is limited to IOS clarity through Meraki Systems Manager for the conference IOS devices. Most of the asset information we need about the iPhones/iPads is brought in through the SecureX Device Insights inventory. However, for initial configuration and to view device trajectory it is required to log into Secure Endpoint. A new Secure Endpoint account can be created under Accounts à Users and an invite is sent to corresponding email address. Accepting the invite is a smooth process since the user is already signed in with SecureX sign-on. Privileges for the user in the Endpoint console can be granted from within the user account.
Conclusion:
To sum it all up, SecureX sign-on is the standard for the Cisco stack moving forward. With a new SecureX organization instantiated using SecureX sign-on any new users to the Cisco stack at Black Hat will be using SecureX sign-on. SecureX sign-on has helped our user management be much more secure as we have expanded our presence at Black Hat. SecureX sign-on provides a unified login mechanism for all the products and modernized our login experience at the conference.
Malware Threat Intelligence made easy and available, with Cisco Secure Malware Analytics and SecureX by Ben Greenbaum
I’d gotten used to people’s reactions upon seeing SecureX in use for the first time. A few times at Black Hat, a small audience gathered just to watch us effortlessly correlate data from multiple threat intelligence repositories and several security sensor networks in just a few clicks in a single interface for rapid sequencing of events and an intuitive understanding of security events, situations, causes, and consequences. You’ve already read about a few of these instances above. Here is just one example of SecureX automatically putting together a chronological history of observed network events detected by products from two vendors (Cisco Umbrella and NetWitness) . The participation of NetWitness in this and all of our other investigations was made possible by our open architecture, available APIs and API specifications, and the creation of the NetWitness module described above.
In addition to the traffic and online activities of hundreds of user devices on the network, we were responsible for monitoring a handful of Black Hat-owned devices as well. Secure X Device Insights made it easy to access information about these assets, either en masse or as required during an ongoing investigation. iOS Clarity for Secure Endpoint and Meraki System Manager both contributed to this useful tool which adds business intelligence and asset context to SecureX’s native event and threat intelligence, for more complete and more actionable security intelligence overall.
SecureX is made possible by dozens of integrations, each bringing their own unique information and capabilities. This time though, for me, the star of the SecureX show was our malware analysis engine, Cisco Secure Malware Analytics (CSMA). Shortly before Black Hat Asia, the CSMA team released a new version of their SecureX module. SecureX can now query CSMA’s database of malware behavior and activity, including all relevant indicators and observables, as an automated part of the regular process of any investigation performed in SecureX Threat Response.
This capability is most useful in two scenarios:
1: determining if suspicious domains, IPs and files reported by any other technology had been observed in the analysis of any of the millions of publicly submitted file samples, or our own.
2: rapidly gathering additional context about files submitted to the analysis engine by the integrated products in the Black Hat NOC.
The first was a significant time saver in several investigations. In the example below, we received an alert about connections to a suspicious domain. In that scenario, our first course of action is to investigate the domain and any other observables reported with it (typically the internal and public IPs included in the alert). Due to the new CSMA module, we immediately discovered that the domain had a history of being contacted by a variety of malware samples, from multiple families, and that information, corroborated by automatically gathered reputation information from multiple sources about each of those files, gave us an immediate next direction to investigate as we hunted for evidence of those files being present in network traffic or of any traffic to other C&C resources known to be used by those families. From the first alert to having a robust, data-driven set of related signals to look for, took only minutes, including from SecureX partner Recorded Future, who donated a full threat intelligence license for the Black Hat NOC.
The other scenario, investigating files submitted for analysis, came up less frequently but when it did, the CSMA/SecureX integration was equally impressive. We could rapidly, nearly immediately, look for evidence of any of our analyzed samples in the environment across all other deployed SecureX-compatible technologies. That evidence was no longer limited to searching for the hash itself, but included any of the network resources or dropped payloads associated with the sample as well, easily identifying local targets who had not perhaps seen the exact variant submitted, but who had nonetheless been in contact with that sample’s Command and Control infrastructure or other related artifacts.
And of course, thanks to the presence of the ribbon in the CSMA UI, we could be even more efficient and do this with multiple samples at once.
SecureX greatly increased the efficiency of our small volunteer team, and certainly made it possible for us to investigate more alerts and events, and hunt for more threats, all more thoroughly, than we would have been able to without it. SecureX truly took this team to the next level, by augmenting and operationalizing the tools and the staff that we had at our disposal.
We look forward to seeing you at Black Hat USA in Las Vegas, 6-11 August 2022!

About Black Hat
For more than 20 years, Black Hat has provided attendees with the very latest in information security research, development, and trends. These high-profile global events and trainings are driven by the needs of the security community, striving to bring together the best minds in the industry. Black Hat inspires professionals at all career levels, encouraging growth and collaboration among academia, world-class researchers, and leaders in the public and private sectors. Black Hat Briefings and Trainings are held annually in the United States, Europe and Asia. More information is available at: blackhat.com. Black Hat is brought to you by Informa Tech.
In part one of this issue of our Black Hat Asia NOC blog, you will find:
Cisco Meraki was asked by Black Hat Events to be the Official Wired and Wireless Network Equipment, for Black Hat Asia 2022, in Singapore, 10-13 May 2022; in addition to providing the Mobile Device Management (since Black Hat USA 2021), Malware Analysis (since Black Hat USA 2016), & DNS (since Black Hat USA 2017) for the Network Operations Center. We were proud to collaborate with NOC partners Gigamon, IronNet, MyRepublic, NetWitness and Palo Alto Networks.
To accomplish this undertaking in a few weeks’ time, after the conference had a green light with the new COVID protocols, Cisco Meraki and Cisco Secure leadership gave their full support to send the necessary hardware, software licenses and staff to Singapore. Thirteen Cisco engineers deployed to the Marina Bay Sands Convention Center, from Singapore, Australia, United States and United Kingdom; with two additional remote Cisco engineers from the United States.
From attendee to press to volunteer – coming back to Black Hat as NOC volunteer by Humphrey Cheung
Loops in the networking world are usually considered a bad thing. Spanning tree loops and routing loops happen in an instant and can ruin your whole day, but over the 2nd week in May, I made a different kind of loop. Twenty years ago, I first attended the Black Hat and Defcon conventions – yay Caesars Palace and Alexis Park – a wide-eyed tech newbie who barely knew what WEP hacking, Driftnet image stealing and session hijacking meant. The community was amazing and the friendships and knowledge I gained, springboarded my IT career.
In 2005, I was lucky enough to become a Senior Editor at Tom’s Hardware Guide and attended Black Hat as accredited press from 2005 to 2008. From writing about the latest hardware zero-days to learning how to steal cookies from the master himself, Robert Graham, I can say, without any doubt, Black Hat and Defcon were my favorite events of the year.
Since 2016, I have been a Technical Solutions Architect at Cisco Meraki and have worked on insanely large Meraki installations – some with twenty thousand branches and more than a hundred thousand access points, so setting up the Black Hat network should be a piece of cake right? Heck no, this is unlike any network you’ve experienced!
As an attendee and press, I took the Black Hat network for granted. To take a phrase that we often hear about Cisco Meraki equipment, “it just works”. Back then, while I did see access points and switches around the show, I never really dived into how everything was set up.
A serious challenge was to secure the needed hardware and ship it in time for the conference, given the global supply chain issues. Special recognition to Jeffry Handal for locating the hardware and obtaining the approvals to donate to Black Hat Events. For Black Hat Asia, Cisco Meraki shipped:
Let’s start with availability. iPads and iPhones are scanning QR codes to register attendees. Badge printers need access to the registration system. Training rooms all have their separate wireless networks – after all, Black Hat attendees get a baptism by fire on network defense and attack. To top it all off, hundreds of attendees gulped down terabytes of data through the main conference wireless network.
All this connectivity was provided by Cisco Meraki access points, switches, security appliances, along with integrations into SecureX, Umbrella and other products. We fielded a literal army of engineers to stand up the network in less than two days… just in time for the training sessions on May 10 to 13th and throughout the Black Hat Briefings and Business Hall on May 12 and 13.
Let’s talk security and visibility. For a few days, the Black Hat network is probably one of the most hostile in the world. Attendees learn new exploits, download new tools and are encouraged to test them out. Being able to drill down on attendee connection details and traffic was instrumental on ensuring attendees didn’t get too crazy.
On the wireless front, we made extensive use of our Radio Profiles to reduce interference by tuning power and channel settings. We enabled band steering to get more clients on the 5GHz bands versus 2.4GHz and watched the Location Heatmap like a hawk looking for hotspots and dead areas. Handling the barrage of wireless change requests – enable or disabling this SSID, moving VLANs (Virtual Local Area Networks), enabling tunneling or NAT mode, – was a snap with the Meraki Dashboard.
While the Cisco Meraki Dashboard is extremely powerful, we happily supported exporting of logs and integration in major event collectors, such as the NetWitness SIEM and even the Palo Alto firewall. On Thursday morning, the NOC team found a potentially malicious Macbook Pro performing vulnerability scans against the Black Hat management network. It is a balance, as we must allow trainings and demos connect to malicious websites, download malware and execute. However, there is a Code of Conduct to which all attendees are expected to follow and is posted at Registration with a QR code.
The Cisco Meraki network was exporting syslog and other information to the Palo Alto firewall, and after correlating the data between the Palo Alto Dashboard and Cisco Meraki client details page, we tracked down the laptop to the Business Hall.
We briefed the NOC management, who confirmed the scanning was violation of the Code of Conduct, and the device was blocked in the Meraki Dashboard, with the instruction to come to the NOC.
The device name and location made it very easy to determine to whom it belonged in the conference attendees.
A delegation from the NOC went to the Business Hall, politely waited for the demo to finish at the booth and had a thoughtful conversation with the person about scanning the network.
Coming back to Black Hat as a NOC volunteer was an amazing experience. While it made for long days with little sleep, I really can’t think of a better way to give back to the conference that helped jumpstart my professional career.
Meraki MR, MS, MX and Systems Manager by Paul Fidler
With the invitation extended to Cisco Meraki to provide network access, both from a wired and wireless perspective, there was an opportunity to show the value of the Meraki platform integration capabilities of Access Points (AP), switches, security appliances and mobile device management.
The first amongst this was the use of the Meraki API. We were able to import the list of MAC addresses of the Meraki MRs, to ensure that the APs were named appropriately and tagged, using a single source of truth document shared with the NOC management and partners, with the ability to update en masse at any time.
On the first day of NOC setup, the Cisco team walked around the venue to discuss AP placements with the staff of the Marina Bay Sands. Whilst we had a simple Powerpoint showing approximate AP placements for the conference, it was noted that the venue team had an incredibly detailed floor plan of the venue. This was acquired in PDF and uploaded into the Meraki Dashboard; and with a little fine tuning, aligned perfectly with the Google Map.
Meraki APs were then placed physically in the venue meeting and training rooms, and very roughly on the floor plan. One of the team members then used a printout of the floor plan to mark accurately the placement of the APs. Having the APs named, as mentioned above, made this an easy task (walking around the venue notwithstanding!). This enabled accurate heatmap capability.
The Location Heatmap was a new capability for Black Hat NOC, and the client data visualized in NOC continued to be of great interest to the Black Hat management team, such as which training, briefing and sponsor booths drew the most interest.
The ability to use SSID Availability was incredibly useful. It allowed ALL of the access points to be placed within a single Meraki Network. Not only that, because of the training events happening during the week, as well as TWO dedicated SSIDs for the Registration and lead tracking iOS devices (more of which later), one for initial provisioning (which was later turned off), and one for certificated based authentication, for a very secure connection.
We were able to monitor the number of connected clients, network usage, the persons passing by the network and location analytics, throughout the conference days. We provided visibility access to the Black Hat NOC management and the technology partners (along with full API access), so they could integrate with the network platform.
Meraki alerts are exactly that: the ability to be alerted to something that happens in the Dashboard. Default behavior is to be emailed when something happens. Obviously, emails got lost in the noise, so a web hook was created in SecureX orchestration to be able to consume Meraki alerts and send it to Slack (the messaging platform within the Black Hat NOC), using the native template in the Meraki Dashboard. The first alert to be created was to be alerted if an AP went down. We were to be alerted after five minutes of an AP going down, which is the smallest amount of time available before being alerted.
The bot was ready; however, the APs stayed up the entire time!
Applying the lessons learned at Black Hat Europe 2021, for the initial configuration of the conference iOS devices, we set up the Registration iPads and lead retrieval iPhones with Umbrella, Secure Endpoint and WiFi config. Devices were, as in London, initially configured using Apple Configurator, to both supervise and enroll the devices into a new Meraki Systems Manager instance in the Dashboard.
However, Black Hat Asia 2022 offered us a unique opportunity to show off some of the more integrated functionality.
System Apps were hidden and various restrictions (disallow joining of unknown networks, disallow tethering to computers, etc.) were applied, as well as a standard WPA2 SSID for the devices that the device vendor had set up (we gave them the name of the SSID and Password).
We also stood up a new SSID and turned-on Sentry, which allows you to provision managed devices with, not only the SSID information, but also a dynamically generated certificate. The certificate authority and radius server needed to do this 802.1x is included in the Meraki Dashboard automatically! When the device attempts to authenticate to the network, if it doesn’t have the certificate, it doesn’t get access. This SSID, using SSID availability, was only available to the access points in the Registration area.
Using the Sentry allowed us to easily identify devices in the client list.
One of the alerts generated with SysLog by Meraki, and then viewable and correlated in the NetWitness SIEM, was a ‘De Auth’ event that came from an access point. Whilst we had the IP address of the device, making it easy to find, because the event was a de auth, meaning 802.1x, it narrowed down the devices to JUST the iPads and iPhones used for registration (as all other access points were using WPA2). This was further enhanced by seeing the certificate name used in the de-auth:
Along with the certificate name was the name of the AP: R**
One of the inherent problems with iOS device location is when devices are used indoors, as GPS signals just aren’t strong enough to penetrate modern buildings. However, because the accurate location of the Meraki access points was placed on the floor plan in the Dashboard, and because the Meraki Systems Manager iOS devices were in the same Dashboard organization as the access points, we got to see a much more accurate map of devices compared to Black Hat Europe 2021 in London.
When the conference Registration closed on the last day and the Business Hall Sponsors all returned their iPhones, we were able to remotely wipe all of the devices, removing all attendee data, prior to returning to the device contractor.
Meraki Scanning API Receiver by Christian Clasen
Leveraging the ubiquity of both WiFi and Bluetooth radios in mobile devices and laptops, Cisco Meraki’s wireless access points can detect and provide location analytics to report on user foot traffic behavior. This can be useful in retail scenarios where customers desire location and movement data to better understand the trends of engagement in their physical stores.
Meraki can aggregate real-time data of detected WiFi and Bluetooth devices and triangulate their location rather precisely when the floorplan and AP placement has been diligently designed and documented. At the Black Hat Asia conference, we made sure to properly map the AP locations carefully to ensure the highest accuracy possible.
This scanning data is available for clients whether they are associated with the access points or not. At the conference, we were able to get very detailed heatmaps and time-lapse animations representing the movement of attendees throughout the day. This data is valuable to conference organizers in determining the popularity of certain talks, and the attendance at things like keynote presentations and foot traffic at booths.
This was great for monitoring during the event, but the Dashboard would only provide 24-hours of scanning data, limiting what we could do when it came to long-term data analysis. Fortunately for us, Meraki offers an API service we can use to capture this treasure trove offline for further analysis. We only needed to build a receiver for it.
The Scanning API requires that the customer stand up infrastructure to store the data, and then register with the Meraki cloud using a verification code and secret. It is composed of two endpoints:
Returns the validator string in the response body
[GET] https://yourserver/
This endpoint is called by Meraki to validate the receiving server. It expects to receive a string that matches the validator defined in the Meraki Dashboard for the respective network.
Accepts an observation payload from the Meraki cloud
[POST] https://yourserver/
This endpoint is responsible for receiving the observation data provided by Meraki. The URL path should match that of the [GET] request, used for validation.
The response body will consist of an array of JSON objects containing the observations at an aggregate per network level. The JSON will be determined based on WiFi or BLE device observations as indicated in the type parameter.
What we needed was a simple technology stack that would contain (at minimum) a publicly accessible web server capable of TLS. In the end, the simplest implementation was a web server written using Python Flask, in a Docker container, deployed in AWS, connected through ngrok.
In fewer than 50 lines of Python, we could accept the inbound connection from Meraki and reply with the chosen verification code. We would then listen for the incoming POST data and dump it into a local data store for future analysis. Since this was to be a temporary solution (the duration of the four-day conference), the thought of registering a public domain and configuring TLS certificates wasn’t particularly appealing. An excellent solution for these types of API integrations is ngrok (https://ngrok.com/). And a handy Python wrapper was available for simple integration into the script (https://pyngrok.readthedocs.io/en/latest/index.html).
We wanted to easily re-use this stack next time around, so it only made sense to containerize it in Docker. This way, the whole thing could be stood up at the next conference, with one simple command. The image we ended up with would mount a local volume, so that the ingested data would remain persistent across container restarts.
Ngrok allowed us to create a secure tunnel from the container that could be connected in the cloud to a publicly resolvable domain with a trusted TLS certificate generated for us. Adding that URL to the Meraki Dashboard is all we needed to do start ingesting the massive treasure trove of location data from the Aps – nearly 1GB of JSON over 24 hours.
This “quick and dirty” solution illustrated the importance of interoperability and openness in the technology space when enabling security operations to gather and analyze the data they require to monitor and secure events like Black Hat, and their enterprise networks as well. It served us well during the conference and will certainly be used again going forward.

As an avid internet surfer, you’ve most likely heard of cookies. No, we’re not talking about the ones filled with chocolate chips. We’re talking about the ones that allow you to log in to your favorite websites. Cookies may impact your online security, so check out these tips to manage them and keep your online accounts safe.
Ever wonder how a website saves the items you placed in your shopping cart last week, even though you closed the tab before making the purchase? This is made possible by cookies. According to the Federal Trade Commission, a cookie is information saved by your web browser. When you visit a website, the site may place a cookie on your web browser so it can recognize your device in the future. If you return to that site later, it can read that cookie to remember you from your last visit, keeping track of your activities over time.1
Cookies come in either the first-party or third-party variety. There’s no difference between the two in how they function, but rather in where and how you encountered them. First-party cookies belong to sites you visited first-hand in your browser. Third-party cookies, or “tracking cookies,” generally come from third-party advertising websites.
Although cookies generally function the same, there are technically two different types of cookies. Magic cookies refer to packets of information that are sent and received without changes. Historically, this would be used to log in to a computer database system, such as an internal business network. This concept predates the modern cookie we use today.
HTTP cookies are a repurposed version of the magic cookie built for internet browsing and managing online experiences. HTTP cookies help web developers give you more personalized, convenient website experiences. They allow sites to remember you, your website logins, and shopping carts so you can pick back up where you left off from your last visit. However, cybercriminals can manipulate HTTP cookies to spy on your online activity and steal your personal information.
Cookie hijacking (also known as session hijacking) is typically initiated when a cybercriminal sends you a fake login page. If you click the fake link, the thief can steal the cookie and capture anything you type while on the fraudulent website. Like a phishing attack, cookie hijacking allows a cybercriminal to steal personal information like usernames, passwords, and other important data held within the cookie. If you enter your information while on the fake website, the criminal can then put that cookie in their browser and impersonate you online. They may even change your credentials, locking you out of your account.
Sometimes, criminals initiate cookie hijacking attacks without a fake link. If you’re browsing on an unsecured, public Wi-Fi connection, hackers can easily steal your data that’s traveling through the connection. This can happen even if the site is secure and your username and password are encrypted.
Because the data in cookies doesn’t change, cookies themselves aren’t harmful. They can’t infect computers with viruses or malware. But if your cookies are hijacked as part of a cyberattack, a criminal could gain access to your browsing history and use cookies as the key to enter your locked accounts. For example, a hacker may steal your identity or confidential company information, purchase items in your online shopping carts, or loot your bank account.
Preventing cookie hijacking attacks can allow you to browse the internet with greater peace of mind. Follow these tips to not only safeguard your personal information but to also enhance your browsing experience:
Make it a habit to clear your cookie cache regularly to prevent cookie overload, which could slow your search speeds. Also, almost every browser has the option to enable/disable cookies on your computer. So if you don’t want them at all, your browser’s support section can walk you through how to disable them.
Although it’s convenient to not have to re-type your credentials into a website you frequently visit, autofill features could make it easier for a criminal to extract your data with cookie hijacking. Plus, autofill is risky if your physical device falls into the wrong hands. To browse more securely without having to constantly reenter your passwords, use a password manager like McAfee True Key. True Key makes it so you only have to remember one master password, and it encrypts the rest in a vault protected by one of the most secure encryption algorithms available.
Strong, unique passwords for each of your accounts, updated regularly, offer ample protection against hackers. Multi-factor authentication (MFA) adds yet another layer of security by double-checking your identity beyond your username and password, usually with a texted or emailed code. When your accounts offer MFA, always opt in.
Criminals can hijack your cookies if you’re browsing on an unsecured, public Wi-Fi connection. To prevent a criminal from swiping your data, use a virtual private network (VPN), a service that protects your data and privacy online. A VPN creates an encrypted tunnel that makes you anonymous by masking your IP address while connecting to public Wi-Fi hotspots. This is a great way to shield your information from online spies while you’re banking, shopping, or handling any kind of sensitive information online.

A-list celebrities and social media influencers are now adding their voices to the roar of other cryptocurrency fans asking you to join them in the investments of the future. It’s impossible to deny the grip cryptocurrencies have on the world today, for better or worse. In some industries, they speed the pace of business and for some, it’s a viable way to make ends meet and set up long-term investments. The cryptocurrency realm has also proven to be vulnerable to cybercriminals. For example, the Wormhole hack leaked $320 million, and cybercriminals have targeted crypto platforms with ransomware and mining app scams.
Whether you’re already in the cryptocurrency game or are thinking about taking the plunge, here’s what you need to know about crypto wallets and tips on how to keep yours safe from cybercriminals.
A cryptocurrency wallet, or crypto wallet, is a software product or a physical device that stores the public and private keys to your cryptocurrency accounts. Keys are strings of numbers and letters that encrypt and decrypt crypto transactions and secure crypto accounts. You can think of public keys as the routing and account numbers that appear at the bottom of paper checks. There’s not much a nefarious character can do with that information, and it’s totally normal to give that information to an acquaintance with whom you’re doing business. Private keys are like your online banking password or debit PIN. Those you must guard very closely because in the wrong hands, your hard-earned bank balance could disappear. A crypto wallet also allows you to transfer funds between crypto types and make transactions.
Here are a few basic types of crypto wallets to help you decide which type is right for you.
A non-custodial wallet means that you are the sole keeper of the keys to your crypto assets. If you forget your password, there’s no “forgot your password?” prompt to let you back in. While not having this safety net is a little nerve wracking, noncustodial wallets are considered the more secure option. You don’t have to worry about a security breach of a major corporation leaking your private key. If you’re responsible and confident that you’re prepared to look after your assets by yourself, this may be the best option for you.
A custodial wallet is a little less secure, but you have a third party helping you log in and manage your crypto accounts. Custodial wallets are often web-based, and the biggest tick in their pro column is that they’re generally very easy to use. While reputable custodial wallets take security very seriously, the threat of a breach is always a possibility, especially as crypto accounts are appealing targets to cybercriminals.
Hardware wallets, also known as cold wallets, are devices you can fit in the palm of your hand. Most models are Bluetooth-enabled devices that look like small remote controls or are flash drives. The device is secured by a PIN that you should never write down or share with anyone else. Also, you should designate a safe and private spot to store your hardware wallet. Similar to a noncustodial wallet, you are solely responsible for keeping track of the device and remembering the PIN. If you lose it, your crypto accounts are locked, and there’s no locksmith to open them for you. As long as you keep track of it, hardware wallets are very secure. Most models are equipped with malware- and virus-proofing security features.
Software wallets are downloaded and internet-connected mobile or desktop apps. They allow you to make transactions on the run, as you can access your crypto accounts from your phone. In that sense, they’re more convenient than hardware wallets. Additionally, software wallets have the same safety net as custodial wallets: if you lose your phone, forget your password, or require login assistance, the maker of the software can help you access your accounts. Software wallets are very secure when you enable their two-factor authentication login settings; however, since they connect to the internet, there’s always a chance a cybercriminal could break-in. Thus, hardware wallets are considered more secure than the software variety.
Check out these tips to ensure your assets are safe and secure in your crypto wallet:
Cryptocurrency value is reaching galactic heights like the spaceships depicted in prime-time ads. Don’t feel pressured to hop aboard the crypto rocket, but if you do decide to jump on, make sure you do your research carefully and make the best decisions for your crypto goals.

Whether it’s for routine care, a prescription refill, or a simple follow-up, online doctor visits offer tremendous benefits in terms of both convenience and ease of care—all good reasons to help mom and dad get connected with it.
There’s no doubt that more older adults than ever are taking advantage of online doctor visits, more formally known as telemedicine. While usage numbers have risen dramatically across all age groups, it’s particularly so for elders. Pre- and post-pandemic numbers saw a 63-fold increase in Medicare telemedicine use.
However, many older patients are missing out and not using telemedicine for one reason or another. What’s holding them back? Several things, according to research from the University of California, San Francisco:
Moreover, another issue is that many older adults do not know that telemedicine is an option. Research from the University of Michigan showed that 55% of older adults surveyed were unaware if their healthcare provider even offered telemedicine as a service. And perhaps quite telling is that the same survey revealed nearly half of older adults harbored concerns about privacy and did not feel personally connected to their care provider during their visits.
For us as children and grandchildren of older adults, it can be tough knowing that a loved one is missing out on an avenue of care that they could otherwise benefit from. While we absolutely respect what they feel is comfortable and trustworthy for them, there are several other areas where we can help the older loved ones in our lives overcome the issues and concerns they face.
With that, let’s talk about the technology behind telemedicine and how you can help them use it, and address some of those privacy issues as well.
As indicated above, paying a visit to the doctor via telemedicine can be a big jump. Just as the idea of it is new for many of us, it’s yet newer for older adults. There’s a good chance that you’re familiar with video chats and calls already, which gives you a foundation we can work with when it’s time to see the doctor on a screen. That may not be the case for older adults. Add that into the privacy concerns and decades of seeing a doctor in person, you can see why some older adults simply choose to opt-out.
One way you can help is to have a few video chats with your older loved ones. In addition to the regular calls you make, you might want to try having a video chat with them from time to time. It’s an outstanding way to spend time together when you can’t be together in person, and it may develop a comfort level with the technology so that they may be willing to give telemedicine a try. You can check out my earlier article in this series that covers video chats with mom and dad, along with straightforward steps to get them up and running on the technology and how to use it.
One thing your parents will need for their visit is a reliable device that they’re comfortable using. It could be a computer or laptop, or it may be a smartphone or tablet. Note that in some cases their healthcare provider may use a telemedicine solution that has certain requirements as well, so you’ll want to see what those are and ensure that the device mom or dad has is compatible. (For example, the care provider may have an app that’s available through the Apple App Store or Google Play. Others may have an online platform that can be accessed by several different kinds of devices.)
If they’re using a smartphone or tablet, that will likely make things easier because the camera and microphone are already integrated into the device—all set up and ready to go. For a computer or laptop, you can help them get familiar with the setup, like the microphone levels, speaker volume, and camera. For audio, you can see a set of headphones or smartphone earbuds work well for them, which can help prevent audio feedback loops and simply make it easier to hear the caregiver.
If you’re looking for a little assistance with a Windows computer, you can check out this quick article for setting up the audio and this article for setting up the camera. For Macs, check out this article for audio and this article for the video.
If they don’t already have comprehensive online protection software for their devices, look into getting it. This will protect them against malware, viruses, and phishing attacks. They’ll also benefit from other features that help them manage their passwords, protect their identity, safeguard their privacy, and more.
As for privacy in general, medical information is among the most precious information any of us have. For example, here in the U.S., we have HIPPA privacy standards to protect our medical records and conversations. Yet there’s also the issue of eavesdropping, which is a risk in practically any online communication.
To help address privacy issues and concerns, health care providers will often post a set of Frequently Asked Questions (FAQ) as part of their telemedicine service. Within that, you’ll very likely find a section on personal privacy and the technologies in place to protect it. Here’s a good example of a telemedicine FAQ from the University of Washington Medicine and another example from the telemedicine page that Virginia Mason/Franciscan Health designed for its patients.
In all, if your parents have concerns about their privacy, you can absolutely assure them that it’s a valid concern. Consult the provider’s FAQ for guidance. If either of you has further questions, feel free to call the healthcare provider and speak with them.
In addition to digital security, there’s the possibility of physical eavesdropping, somebody actually listening in on their conversation from another room, apartment, or from the street. Help your older loved ones pick a place in their home where they can have some privacy and where they can’t be overheard by neighbors and passers-by. A bedroom is a fine place—or any location that’s familiar and comfortable as well. When choosing a private place, a well-lit location is important as well so that the camera captures a nice and clear image.
Additionally, you can help them prep for their visit by putting together a list of things to discuss during the visit. The U.S. Department of Health and Human Services suggests writing things down:
In addition to the above, there are further measures you can help your parents or older loved one take to further secure their telemedicine visit—and their internet usage in general.
Your telemedicine visit may require setting up a new account and password. When doing so, make sure it’s with a strong, unique password. A password manager can help. Also found in comprehensive online protection software, a password manager can create and securely store strong and unique passwords for your mom and dad, giving them one less thing they need to remember and worry about.
A VPN, or virtual private network, offers a strong layer of additional protection when you’re transmitting health data or simply having a private conversation about your health with a professional. A VPN creates an encrypted tunnel to keep you and your activity anonymous. In effect, your data is scrambled and hidden to anyone outside your VPN tunnel, thus making your private information difficult to collect. Check with the care provider to see if their telemedicine solution uses a VPN. If not, you can always get a VPN as part of your online protection software.
Beyond their devices, securing their internet router is an important step in making a telemedicine visit safe and secure. The data that travels along it is of a highly personal nature already, so make sure the router has a strong and unique password. Also, change the name of their router so it doesn’t give away their address or any other signs of their identity. One more step is to check that your router is using an encryption method, like WPA2, which will keep your signal secure. If you have questions, check with their internet provider—they may even offer up a newer, more secure router to replace an older one.
As with anything concerning their health, have your parents and loved ones consult with their caregivers to ensure that a telemedicine visit is a proper course for them.
So while the technical ins and outs of preparing for a telemedicine visit may have their challenges for some older adults, we should also realize that getting comfortable with the idea of a telemedicine visit in the first place may take some time and effort. Starting with regular video chats with the family may increase familiarity and ease with holding a conversation over video. Likewise, having a conversation with their doctor about telemedicine may put some concerns to rest as well. After all, they will have a relationship with their doctor. Getting the facts from the doctor, face to face may help.
We all want what’s best, particularly when it comes to the care of our parents and older loved ones in our lives, and choosing to try telemedicine is a highly personal decision for them. I hope this article and the resources cited within it will help you enable them to make the choice that’s comfortable, effective, and right for them.

Have you ever been online and replied to a comment or post? Maybe it was on Reddit or on an influencer’s Instagram. Did other people reply to you, and were any of them unexpectedly hostile? When you’re online, a little hostility is sadly par for the course, but most people brush it off and move on to enjoy other aspects of life online. But what would you do if that unpleasant interaction went much farther than was reasonable? What if one day you discovered the most important parts of your identity had been maliciously and intentionally revealed online? Let’s talk about doxxing – what it is and how you can avoid becoming a victim of this kind of harassment.
Doxxing, derived from the hacker term “dropping docs”, is internet slang for revealing someone’s identity online for the purposes of harassing them. It usually goes way beyond simply revealing someone’s email address or name and may involve personal information like a home address or workplace, SSN, financial information, phone number, pictures, texts, IP address, and other important details. The tricky thing about doxxing is that aspects of it may not be a crime, depending on what you’ve made publicly available online. However, the context in which doxxing occurs is crucial. Often it’s the first step taken to incite more severe harassment. For instance, the doxxer may not plan on taking action against their target but instead hope that someone else does. When put up against a recent Pew Research report showing that 41% of U.S. web users experience harassment in some form, it’s clear that Doxxing is a dangerous trend online.
Doxxing is a problem that’s grown in scope simply because there’s so much more data about us being kept online. Third-party services, called data brokers, capture our account info, the sites we visit, how long we spent on them, and other kinds of metadata to create profiles they then resell to advertisers. If someone gets access to these troves of data, they can reveal extremely damaging information about an individual, or data that allows a person to be damaged. For instance, with a phone number and a current address, some criminals were able to call in SWAT teams on innocent individuals. Political dissidents are often doxxed by the governments their protesting against. And on a lighter note, the adult website Ashley Madison, which promotes extramarital affairs, had their members’ data leaked online, to the embarrassment of a few public figures.
The response should be very similar to the one you’d take if your wallet was stolen. Move fast, stem the loss, and begin remediation as soon as possible. Here are some broad steps that can be taken.
Of course, not being doxxed in the first place is the ultimate goal of a proactive online protection plan. Here’s what we recommend:
Identity theft protection services help protect your data, monitor your online accounts like emails, SSNs, and more. In addition to online monitoring, they should also offer insurance and even theft remediation if the worst should occur.
Before you tag your location, friends, or workplace in a photo think about who has access to this information. What’s gained or lost by sharing all that info? Also, security questions for your accounts should not use the name of your pet or your first-born child if you have posted those on Facebook.
Public Wi-Fi networks at coffee shops and airports may not be secure against hackers and snooping. That’s why we recommend using a VPN whenever you’re connected online. This powerful tool hides your activity and location whenever you’re online on an unsecured network.
Googling yourself is a great way to see if anyone is using your online identity in bad ways.
Social networks allow you to control who can see your data. Usually, with a few clicks, you can restrict what you show online to a great degree. For instance, makes your payments viewable to other users as a default, but can easily be changed to hide them from the public.
Using long, complex, unique passwords for every account is convenient and maybe the best way to prevent your information from being stolen. Yes, we said convenient because with a password manager you only need to remember one key to create and manage much longer ones for all your most important accounts.
The reality is that the more we live online, the more our identities will too. This does not mean we need to live a restricted life online. In fact, using comprehensive online protection, which features most of the tools above, we can remain free to enjoy life on our terms. Doxxing is something to be aware of, but with great protection, it’s far from anything we need to be worried about as we make the most of our lives online.

The internet has opened up wonderful new possibilities in our world, making life easier on many levels. You can pay your bills, schedule your next family vacation, and order groceries with the click of a button. While the internet offers many positive benefits, it also has some negatives. Although not entirely used for illicit purposes, the dark web is one part of the internet that can be used by criminals for illegal purposes, like selling stolen personal information.
But just what is the dark web? Basically, it’s a part of the internet that isn’t indexed by search engines. As an average internet user, you won’t come across the dark web since you need a special browser to access it. It’s certainly not something you need to stress about in your day-to-day browsing, and you shouldn’t let it scare you off the internet. Unless you actively seek it out, you’ll likely never have any contact with the dark web in your lifetime.
A better understanding of what the dark web is and the possible threats it contains can help you protect yourself, though. This guide provides the essential information you need, explaining the different levels of the web and revealing how you can stay safe. With this knowledge, you can continue to browse online with confidence. Find out more below.
The “dark web” refers to websites that aren’t indexed by search engines like Google and Bing. This might seem strange since most people want their websites to be found through specific searches. Practices like search engine optimization (SEO) are specifically implemented to help websites perform well and rank higher in search engine results.
So, why would someone not want their website to be picked up by a search engine? The primary purpose is to preserve privacy and anonymity. The individuals and organizations on the dark web often engage in illegal activities and want to keep their identities hidden — something that is difficult to do with an indexed website.
It’s important to note that the dark web should not be confused with the deep web, which is a part of the internet individuals access regularly. Although the terms are sometimes used interchangeably, they actually refer to different things. Deep web content — which isn’t picked up by search engines, either — includes pages that typically require additional credentials to access. Your online banking accounts and email accounts, for instance, are examples of deep web content.
The internet is home to billions of websites — an estimated 1.7 billion to be exact, although that number changes every day as new sites are made and others are deleted. Your daily internet activity likely falls within the publicly available and readily accessible portion of the internet (otherwise known as the surface web). However, there are additional “levels” of the internet beyond that top level. Read on to learn more.
The internet you use to search for more information is referred to as the surface web or open web. This is the readily visible part of the internet anyone can access with an internet connection and a normal web browser like Safari, Mozilla Firefox, or Google Chrome. Other terms for the surface web include the visible web, lightnet, or indexed web.
Examples of content you’ll find on the surface web include:
Basically, the sites you use daily — from your favorite news site to a local restaurant — are part of the surface web. What makes these websites part of the surface web is that they can be located via search queries and have recognizable endings like .com, .edu, .gov, or .org. You are able to find websites on the surface web because they are marked as “indexable,” meaning search engines can index and rank them. The sites are readily available on the search engine results pages (SERPs).
Interestingly, the surface web only makes up around 4% of the total internet, meaning the internet is a lot more than what you see on the surface. Think of it as an ocean — there’s the top layer of water you can see and then there’s the vast world beneath. The remainder of the internet is what’s below the surface.
The deep web refers to any page on the internet that isn’t indexed by search engines as described above. The deep web is the first level beneath the “surface” of the visible web — and it’s significantly larger than the surface web, accounting for an estimated 96% to 99% of the entire internet.
It’s important to note that just because this type of content isn’t on the surface doesn’t mean it’s nefarious or has ill intent. A lot of the time, this content isn’t indexed because it includes pages that are meant to be hidden to protect consumer privacy, such as those that require login credentials.
Here are some examples of content on the deep web:
Essentially, any webpage that requires a login is part of the deep web. That said, deep web content doesn’t necessarily have to fall into any of these categories. Any page that is non-indexable is technically also considered part of the deep web. It doesn’t have to require a login or contain sensitive data. Website creators and managers can mark pages as non-indexable if desired.
It’s worth noting that sometimes a single organization’s website will include elements of both the surface web and the deep web. Take a college or university website, for example. Most schools have a comprehensive website providing information about the school’s history, campus location, student body, available programs of study, extracurricular activities, and more.
However, many schools also have an intranet — sometimes linked from the main university page — that’s accessible only for students or staff. This is where students might sign up for classes and access their school email, for example. Since this is sensitive information and requires a unique login, it doesn’t need to be made publicly available via search engines.
In fact, it’s better in the interest of privacy that these pages aren’t readily visible. It helps to protect the user’s data. From this example, you can see that the “deep web” doesn’t have to be scary, illicit, or illegal. It serves a legitimate and useful purpose. You shouldn’t be afraid of the deep web. It’s further important to distinguish the deep web from the dark web — as the next section explains.
As mentioned, the deep web and the dark web sometimes get confused. However, they are distinct. Technically, the dark web is a niche or subsection within the deep web. It consists of websites that aren’t indexable and can’t be readily found online via web search engines. However, the dark web is a carefully concealed portion of the deep web that people go out of their way to keep hidden.
What makes the dark web distinct from the broader deep web is the fact that dark web content can only be accessed via a special browser. The Tor network is often used to access the dark web.
Additionally, the dark web has a unique registry operator and uses security tools like encryption and firewalls, further making it inaccessible via traditional web browsers. Plus, the dark web relies on randomized network infrastructure, creating virtual traffic tunnels. All of these technical details serve to promote anonymity and protect dark web users’ privacy.
The short answer is no, it’s not illegal to browse the dark web. In fact, there are instances where individuals can use it for good. Whistleblowers, for instance, can find the anonymity available through the dark web valuable when working with the FBI or another law enforcement organization.
That said, while it’s not illegal to browse the dark web, it’s also not completely void of criminal activity. Putting yourself in close proximity with illegal activities is rarely a good idea and could heighten your risk of being targeted by a criminal yourself. It’s often best to leave that part of the deep web alone.
There are also many technological threats on the dark web. Malicious software, also known as malware, is a critical concern and can affect unsuspecting users. Even simply browsing the dark web out of curiosity can expose you to such threats, like phishing malware or keyloggers. While an endpoint security program can identify such threats if they end up on your computer, it’s ideal to avoid them altogether.
Further, if you try to buy something on the dark web — even if it’s not illegal — there’s a chance you’ll be scammed. Dark web criminals use a variety of tricks to con people. For example, they may hold money in escrow but then shut down the e-commerce website and take off with the money. Due to the anonymous nature of the dark web, it’s very difficult for law enforcement to find such perpetrators.
Given its anonymous nature, the dark web clearly has an obvious appeal for cybercriminals. But just what do they use it for? The most obvious type of internet activity is the buying and selling of black market goods and services, from illegal drugs to illegal content. Cybercriminals may also run scams when selling such items, for example by taking a person’s money and not delivering the required product.
There are dark websites dedicated to the purchase and sale of illegal products or services (usually using untraceable cryptocurrencies like bitcoin) including:
Browsers like Tor, an open-source and free software, allow people to access dark websites where these goods are available, like a digital marketplace. These websites may look similar to any other surface or deep website you’d encounter. However, they differ in their domain suffix, ending in “.onion” instead of more obvious options like “.com” (Tor is actually short for The Onion Router, which is also where the term “onion routing” comes from — referring to anonymous communication on the dark web).
Onion sites often use scrambled names that make their URLs difficult to remember, minimizing the odds of being reported to authorities. It’s possible to search the dark web using specialized dark web search engines like Grams or link lists like The Hidden Wiki. However, these sources tend to be slow and unreliable, just like the dark web itself.
Some of this information can be extremely valuable on darknet forums. For example, while a Social Security number might go for $2, email credentials could sell for as much as $120,000. Hackers can make a lot of money and do so with less worry that they might get caught. Thanks to the Tor browser’s layers of encryption and IP scrambling, it’s difficult to track people down on this part of the web.
Again, although the dark web isn’t inherently bad, you should still be proactive in preventing your personal information from falling into the wrong hands. Here are a few ways you can help keep you and your family safe online:
The dark web might sound scary. The fact is, an everyday internet user like yourself likely won’t have any contact with this level of the internet. That said, it’s still important to take as many precautions as you can to keep your family and your technology safe.

It happens with more regularity than any of us like to see. There’s either a headline in your news feed or an email from a website or service you have an account with—there’s been a data breach. So what do you do when you find out that you and your information may have been caught up in a data breach? While it can feel like things are out of your hands, there are actually several things you can do to protect yourself.
Let’s start with a look at what kind of information may be at stake and why crooks value that information so much (it’s more reasons than you may think).
The fact is that plenty of our information is out there on the internet, simply because we go about so much of our day online, whether that involves shopping, banking, getting results from our doctors, or simply hopping online to play a game once in a while.
Naturally, that means the data in any given breach will vary from service to service and platform to platform involved. Certainly, a gaming service will certainly have different information about you than your insurance company. Yet broadly speaking, there’s a broad range of information about you stored in various places, which could include:
As to what gets exposed and when you might find out about it, that can vary greatly as well. One industry research report found that 60% of breaches were discovered in just days from the initial attack while others could take months or even longer to detect. Needless to say, the timeline can get rather stretched before word reaches you, which is a good reason to change your passwords regularly should any of them get swept up in a breach. (An outdated password does a hacker no good—more on that in a bit.)
The answer is plenty. In all, personal information like that listed above has a dollar value to it. In a way, your data and information are a kind of currency because they’re tied to everything from your bank accounts, investments, insurance payments—even tax returns and personal identification like driver’s licenses.
With this information in hand, a crook can commit several types of identity crime—ranging from fraud to theft. In the case of fraud, that could include running up a bill on one of your credits cards or draining one of your bank accounts. In the case of theft, that could see crooks impersonate you so they can open new accounts or services in your name. Beyond that, they may attempt to claim your tax refund or potentially get ID issued in your name as well.
Another possibility is that a hacker will simply sell that information on the dark marketplace, perhaps in large clumps or as individual pieces of information that go for a few dollars each. However it gets sold, these dark-market practices allow other fraudsters and thieves to take advantage of your identity for financial or other gains.
Most breaches are financially motivated, with some researchers saying nearly 90% of breaches are about the money. However, we’ve also seen hackers simply dump stolen information out there for practically anyone to see. The motivations behind them vary, yet could involve anything from damaging the reputation of an organization to cases of revenge.
A list of big data breaches is a blog article of its own, yet here’s a quick list of some of the largest and most impactful breaches we’ve seen in recent years:
Needless to say, it’s not just the big companies that get hit. Healthcare facilities have seen their data breached, along with the operations of popular restaurants. Small businesses find themselves in the crosshairs as well, with one report stating that 43% of data leaks target small businesses. Those may come by way of an attack on where those businesses store their records, a disgruntled employee, or by way of a compromised point-of-sale terminal in their store, office, or location.
In short, when it comes to data breaches, practically any business is a potential target because practically every business is online in some form or fashion. Even if it’s by way of a simple point-of-sale machine.
When a business, service, or organization falls victim to a breach, it doesn’t always mean that you’re automatically a victim too. Your information may not have been caught up in it. However, it’s best to act as if it was. With that, we strongly suggest you take these immediate steps.
Given the possibility that your password may be in the hands of a hacker, change it right away. Strong, unique passwords offer one of your best defenses against hackers. Update them regularly as well. As mentioned above, this can protect you in the event a breach occurs and you don’t find out about it until well after it’s happened. You can spare yourself the upkeep that involves a password manager that can keep on top of it all for you. If your account offers two-factor authentication as part of the login process, make use of it as it adds another layer of security that makes hacking tougher.
If you spot unusual or unfamiliar charges or transactions in your account, bank, or debit card statements, follow up immediately. That could indicate improper use. In general, banks, credit card companies, and many businesses have countermeasures to deal with fraud, along with customer support teams that can help you file a claim if needed.
If you haven’t done so already, consider signing up for a service that can monitor dozens of types of personal information and then alert you if any of them are possibly being misused. Identity protection such as ours gives you the added benefit of a professional recovery specialist who can assist with restoring your affairs in the wake of fraud or theft, plus up to $1 million in insurance coverage.
Our advice is to take a deep breath and get to work. By acting quickly, you can potentially minimize and even prevent any damage that’s done. With that, we have two articles that can help guide the way if you think you’re the victim of identity theft, each featuring a series of straightforward steps you can take to set matters right:
Again, if you have any concerns. Take action. The first steps take only minutes. Even if the result is that you find out all’s well, you’ll have that assurance and you’ll have it rather quickly.
The post What to Do If You’re Caught Up in a Data Breach appeared first on McAfee Blog.
You open up your laptop and check the daily news. You see a headline stating that one of your favorite online retailers was breached and that thousands of their customers’ passwords were exposed. Data breaches like this frequently appear in the news, but many consumers don’t realize the implications these breaches have on their personal privacy. When data breaches occur, oftentimes billions of these hacked login credentials become available on the dark web, neatly packaged for criminals to download.1
Let’s dive into the differences between the deep web and the dark web, how cybercriminals use the dark web, and what you can do to protect your data.
You’ve probably heard of the deep and dark web but may not be aware of their differences.2 First, let’s start by noting that the dark web is always part of the deep web, but the deep web is not always the dark web.
The deep web refers to the pages on the internet that are not indexed in search engines, meaning that you can’t find them by performing a simple Google search. To access these pages, you have to know the exact address to the site and access it with specific software. Most personalized and password-protected sites appear on the deep web because they contain information that is not meant to be accessed by the general public. These sites include a user’s Netflix home page, password-protected sites for banking, and the internal sites of companies, organizations, and schools. These are all examples of legitimate areas of the deep web.
On the other hand, the dark web is the disreputable extension of the deep web. Like the deep web, the dark web also houses sites that are not indexed by search engines, but it also hides a user’s identity and location. It consists mostly of illegal products or content that could be harmful to organizations or the general public. Some examples include stolen credit card numbers, fake IDs, drugs, and hacking tools. To access the dark web, a user needs to download darknet software, the most popular being Tor.
Tor, which stands for “the onion routing project,” was developed by the U.S. Navy for the government in the mid-1990s. It was open-sourced in 2004, and that’s when it went public. Today, Tor is the dark web browser that the majority of people use to surf the internet anonymously. To do this, Tor hides a user’s IP address (or the unique address that identifies an internet-connected device or network) by bouncing their search request to multiple different locations. These bounces also referred to as relays, make it much harder for people to find users on the dark web.
Because of its ability to provide anonymity, the dark web is often tied to the world of cybercrime. Scammers frequently use the dark web to find software that allows them to access other people’s computers, banking credentials, Social Insurance Numbers, and credit card information. You may be wondering how all this private information ended up on the dark web in the first place. Oftentimes when a company is breached and their customers’ data is exposed, the hackers behind the breach will upload the stolen database to the dark web. This allows other cybercriminals to purchase the stolen information and use it to target users with other scams. Say that a criminal finds a database on the dark web that contains a bunch of personal email addresses. They can purchase the database and target every email address with a phishing campaign that contains malicious links that spread malware or attempt to trick users into handing over their username and password combinations.
Incorporating cybersecurity best practices into your daily life can help protect your data from hackers looking to take advantage of the data found on the dark web. Follow these tips to bring yourself greater peace of mind:
The chances of a hacker accessing your data are higher if you use the same credentials across different accounts. That’s why it’s important to use a strong, unique password for each of your online profiles. This minimizes the potential damage that could be done if a hacker does gain access to one of your accounts. You can also use a password manager with a built-in generator to make it easier for you to access and manage passwords. Enabling multi-factor authentication will also ensure that hackers cannot access your information using only your login credentials.
If you receive an email asking you to take immediate action, stop and think. Criminals often convey urgency in their phishing scams in the hopes that an unsuspecting user will click on a malicious link or hand over their personal details without considering the legitimacy of the message. Examine suspicious emails carefully to check for telltale signs of phishing, such as poor grammar, grainy logos, or bogus links. If an email claims to be from a well-known company or brand and asks for your credentials, claims that you need to update your password, or sends you a “free offer,” go directly to the source. Contact customer service through the company’s website (not the email) and inquire about the urgent request.
Be on the lookout for breach notices from relevant companies since they are often the first to know about a data breach impacting their online customers. Create news alerts for companies that have access to your information to stay notified of the latest events.
Additionally, create notifications for your bank and other financial accounts to monitor suspicious activity, such as unauthorized transactions or a drop in credit score. You will be better prepared to mitigate any cybersecurity threats with the right security software and knowledge of the latest risks.
Use a comprehensive security solution like McAfee Total Protection, which includes dark web monitoring for up to 10 email addresses. This software actively monitors the dark web for data breaches and exposed information. Personal details include but are not limited to your date of birth, email addresses, credit card numbers, and personal identification numbers. It also provides steps for remediation after a data breach to help you regain control and the integrity of your data and privacy. With a security solution like this in place, you can continue to live your connected life confidently.

You consider yourself a responsible person when it comes to taking care of your physical possessions. You’ve never left your wallet in a taxi or lost an expensive ring down the drain. You never let your smartphone out of your sight, yet one day you notice it’s acting oddly.
Did you know that your device can fall into cybercriminals’ hands without ever leaving yours? SIM swapping is a method that allows criminals to take control of your smartphone and break into your online accounts.
Don’t worry: there are a few easy steps you can take to safeguard your smartphone from prying eyes and get back to using your devices confidently.
First off, what exactly is a SIM card? SIM stands for subscriber identity module, and it is a memory chip that makes your phone truly yours. It stores your phone plan and phone number, as well as all your photos, texts, contacts, and apps. In most cases, you can pop your SIM card out of an old phone and into a new one to transfer your photos, apps, etc.
Unlike what the name suggests, SIM swapping doesn’t require a cybercriminal to get access to your physical phone and steal your SIM card. SIM swapping can happen remotely. A cybercriminal, with a few important details about your life in hand, can answer security questions correctly, impersonate you, and convince your mobile carrier to reassign your phone number to a new SIM card. At that point, the criminal can get access to your phone’s data and start changing your account passwords to lock you out of your online banking profile, email, and more.
SIM swapping was especially relevant right after the T-Mobile data breach.1 Cybercriminals stole millions of phone numbers and the users’ associated personal details. Criminals could later use these details to SIM swap, allowing them to receive users’ text or email two-factor authentication codes and gain access to their personal accounts.
The most glaring sign that your phone number was reassigned to a new SIM card is that your current phone no longer connects to the cell network. That means you won’t be able to make calls, send texts, or surf the internet when you’re not connected to Wi-Fi. Since most people use their smartphones every day, you’ll likely find out quickly that your phone isn’t functioning as it should.
Additionally, when a SIM card is no longer active, the carrier will often send a notification text. If you receive one of these texts but didn’t deactivate your SIM card, use someone else’s phone or landline to contact your wireless provider.
Check out these tips to keep your device and personal information safe from SIM swapping.
With just a few simple steps, you can feel better about the security of your smartphone, cellphone number, and online accounts. If you’d like extra peace of mind, consider signing up for an identity theft protection service like McAfee Identity Protection Service. McAfee, on average, detects suspicious activity ten months earlier than similar monitoring services. Time is of the essence in cases of SIM swapping and other identity theft schemes. An identity protection partner can restore your confidence in your online activities.

The Robinhood trading platform recently disclosed a data breach that exposed the information of millions of its customers. News of the attack was released on Monday, November 8th along with word the hackers behind it had demanded an extortion payment from the company.
According to Robinhood’s disclosure, the attack occurred on November 3rd, which allowed an unauthorized party to obtain the following:
In addition, smaller groups of Robinhood customers had yet more information compromised. Around 310 people had their names, birth dates, and zip codes exposed in the breach. Another 10 customers had “more extensive account details revealed,” per Robinhood’s disclosure.
Robinhood went on to say, “We believe that no Social Security numbers, bank account numbers, or debit card numbers were exposed and that there has been no financial loss to any customers as a result of the incident.”
Robinhood further stated that the company contained the intrusion and that it promptly informed law enforcement of the extortion demand. Robinhood says that it is continuing to investigate the incident with the assistance of a security firm.
The company advised its customers to visit the Robinhood help center to receive the latest messages from the company, noting that they will never include a link to access an account in a security alert.
Any data breach that you and your information may have been involved in calls for a few quick security steps:
1. Log into your account and update your password with a new one that is strong and unique. Likewise, if you use the same or similar passwords across several accounts, change those as well. (A password manager that’s included with comprehensive online protection software can do that work for you.) Set up two-factor authentication if your account allows for it, as this will provide an extra layer of protection as well.
2. Review your statements for any strange activity—even the smallest of withdrawals or transactions could be the sign of a larger issue.
3. Report any suspected fraud to the company or institution involved. They typically have set policies and procedures in place to provide support.
If you believe that you’ve become a victim of identity theft, file a report with local law enforcement and the Federal Trade Commission (FTC). Law enforcement can provide you with a case number that you may need as part of the recovery process. Likewise, the FTC’s identity theft website provides excellent resources, including a recovery plan and a step-by-step walkthrough if you create an account with them.
For even more information, visit our blog that points out the signs of identity theft and the steps you can take should you find yourself victim.
Given that the breach apparently exposed some 5 million email addresses, there’s the risk that these may end up in the hands of bad actors who may use them for follow-on attacks.
Notable among them would be phishing attacks, where hackers could target Robinhood users with phony messages in an attempt to get affected users to reveal further account information. For example, hackers could potentially create bogus emails that appear to come from Robinhood and direct users to a malicious site that requests account information. As Robinhood stated, the company will never include a link to access an account in a security alert. Users should visit the Robinhood site directly for account information.
This breach could lead to other phishing attacks as well, ones that may or may not pose as communication from Robinhood. Some of these phishing attacks can be rather easy to spot, as they may include typos, poorly rendered logos, or spoofed web addresses. However, some sophisticated hackers can roll out rather polished phishing attacks that can closely resemble legitimate communications.
In all, people can avoid falling victim to phishing attacks by keeping the following in mind:
1. Only access your accounts directly from the official website of the company or financial institution involved. If you receive an email, message, or text alerting you of an issue, do not click any links provided in the communication. Go straight to the site yourself by typing in the proper address and view your account information there. Likewise, calling the customer support line posted on their official site is an option as well.
2. Use comprehensive online protection software that includes a spam filter. This can prevent phishing emails from reaching your inbox in the first place.
3. Get to know the signs of phishing emails. A common sign of a scam is an email, ad, message, or site that simply doesn’t look or read right. (Maybe the grammar is awkward or the logo is grainy or has the colors slightly wrong.) However, some of them can look quite convincing, yet there are still ways to spot an attempted phishing attack.
4. Beware of email attachments you aren’t expecting. This is always good form because hackers love to spike attachments with malware that’s designed to steal your personal information. Whether you get an unexpected attachment from a friend or business, follow up before opening it. That’s a quick way to find out if the attachment is legitimate or not.

The unfortunate fact is that data breaches can and do happen. Many of the larger data breaches make the headlines, yet many more do not—such as the ones that hit small businesses, restaurants, and medical care providers. In the hands of hackers, the information spilled by these breaches can provide them with the building blocks to commit identity theft. As a result, keeping on top of your identity and personal information is a must.
The good news is that you have solid options to prevent them from harming you or at least greatly lessen their potential impact. With identity theft protection, even in the short-term, you can monitor emails addresses and usernames that are being used to breach other accounts. You can monitor dozens of different types of personal information and receive alerts to keep an eye out for misuse. Likewise, it can monitor your email addresses and bank accounts for signs of misuse or fraud, plus provide theft protection and support from a recovery specialist if identity theft, unfortunately, happens to you.
Along those same lines, news of a data breach offers all of us a moment to pause and take stock of just how protected we are. Above and beyond the steps covered above, comprehensive online protection can protect your devices from malware, phishing attacks, malicious websites, and other threats. More importantly, it protects you—your identity and privacy, particularly in times where breaches such as the one we’re talking about here occur with seeming regularity.

When it comes to identity theft, trust your gut when something doesn’t feel right. Follow up. What you’re seeing could be a problem.
A missing bill or a mysterious charge on your credit card could be the tip of an identity theft iceberg, one that can run deep if left unaddressed. Here, we’ll look at several signs of identity theft that likely need some investigation and the steps you can take to take charge of the situation.
Unfortunately, it can happen in several ways.
In the physical world, it can happen simply because you lost your wallet or debit card. However, there are also cases where someone gets your information by going through your mail or trash for bills and statements. In other more extreme cases, theft can happen by someone successfully registering a change of address form in your name (although the U.S. Postal Service has security measures in place that make this difficult).
In the digital world, that’s where the avenues of identity theft blow wide open. It could come by way of a data breach, a thief “skimming” credit card information from a point-of-sale terminal, or by a dedicated crook piecing together various bits of personal information that have been gathered from social media, phishing attacks, or malware designed to harvest information. Additionally, thieves may eavesdrop on public Wi-Fi and steal information from people who’re shopping or banking online without the security of a VPN.
Regardless of how crooks pull it off, identity theft is on the rise. According to the Federal Trade Commission (FTC), identity theft claims jumped up from roughly 650,000 claims in 2019 to nearly 1.4 million in 2020—practically double. Of the reported fraud cases where a dollar loss was reported, the FTC calls out the following top three contact methods for identity theft:
However, phone calls, texts, and email remain the most preferred contact methods that fraudsters use, even if they are less successful in creating dollar losses than malicious websites, ads, and social media.
Identity thieves leave a trail. With your identity in hand, they can charge things to one or more of your existing accounts—and if they have enough information about you, they can even create entirely new accounts in your name. Either way, once an identity thief strikes, you’re probably going to notice that something is wrong. Possible signs include:
As you can see, the signs of possible identity theft can run anywhere from, “Well, that’s strange …” to “OH NO!” However, the good news is that there are several ways to check if someone is using your identity before it becomes a problem – or before it becomes a big problem that gets out of hand.
The point is that if you suspect fraud, you need to act right away. With identity theft becoming increasingly commonplace, many businesses, banks, and organizations have fraud reporting mechanisms in place that can assist you should you have any concerns. With that in mind, here are some immediate steps you can take:
Whether you spot a curious charge on your bank statement or you discover what looks like a fraudulent account when you get your free credit report, let the bank or business involved know you suspect fraud. With a visit to their website, you can track down the appropriate number to call and get the investigation process started.
Some businesses will require you to file a local police report to acquire a case number to complete your claim. Even beyond a business making such a request, filing a report is still a good idea. Identity theft is still theft and reporting it provides an official record of the incident. Should your case of identity theft lead to someone impersonating you or committing a crime in your name, filing a police report right away can help clear your name down the road. Be sure to save any evidence you have, like statements or documents that are associated with the theft. They can help clean up your record as well.
The FTC’s identity theft website is a fantastic resource should you find yourself in need. Above and beyond simply reporting the theft, the FTC can provide you with a step-by-step recovery plan—and even walk you through the process if you create an account with them. Additionally, reporting theft to the FTC can prove helpful if debtors come knocking to collect on any bogus charges in your name. You can provide them with a copy of your FTC report and ask them to stop.
You can place a free one-year fraud alert with one of the major credit bureaus (Experian, TransUnion, Equifax), and they will notify the other two. A fraud alert will make it tougher for thieves to open accounts in your name, as it requires businesses to verify your identity before issuing new credit in your name.
A credit freeze goes a step further. As the name implies, a freeze prohibits creditors from pulling your credit report, which is needed to approve credit. Such a freeze is in place until you lift it, and it will also apply to legitimate queries as well. Thus, if you intend to get a loan or new credit card while a freeze is in place, you’ll likely need to take extra measures to see that through. Contact each of the major credit bureaus (Experian, TransUnion, Equifax) to put a freeze in place or lift it when you’re ready.
This can run the gamut from closing any false accounts that were set up in your name, removing bogus charges, and correcting information in your credit report such as phony addresses or contact information. With your FTC report, you can dispute these discrepancies and have the business correct the record. Be sure to ask for written confirmation and keep a record of all documents and conversations involved.
If you receive a notice from the IRS that someone used your identity to file a tax return in your name, follow the information provided by the IRS in the notice. From there, you can file an identity theft affidavit with the IRS. If the notice mentions that you were paid from an employer you don’t know, contact that employer as well and let them know of possible fraud—namely that someone has stolen your identity and that you don’t truly work for them.
Also, be aware that the IRS has specific guidelines as to how and when they will contact you. As a rule, they will most likely contact you via physical mail delivered by the U.S. Postal Service. (They won’t call or apply harassing pressure tactics—only scammers do that.) Identity-based tax scams are a topic all of their own, and for more on it, you can check out this article on tax scams and how to avoid them.
Another downside of identity theft is that it can mark the start of a long, drawn-out affair. One instance of theft can possibly lead to another, so even what may appear to be an isolated bad charge on your credit card calls for keeping an eye on your identity. Many of the tools you would use up to this point still apply, such as checking up on your credit reports, maintaining fraud alerts as needed, and reviewing your accounts closely.
With all the time we spend online as we bank, shop, and simply surf, we create and share all kinds of personal information—information that can get collected and even stolen. The good news is that you can prevent theft and fraud with online protection software, such as McAfee+ Ultimate.
With McAfee+ Ultimate you can:
In all, it’s our most comprehensive privacy, identity, and device protection plan, built for a time when we rely so heavily on the internet to go about our day, whether that’s work, play, or simply getting things done.
Realizing that you’ve become a victim of identity theft carries plenty of emotion with it, which is understandable—the thief has stolen a part of you to get at your money, information, and even reputation. Once that initial rush of anger and surprise has passed, it’s time to get clinical and get busy. Think like a detective who’s building – and closing – a case. That’s exactly what you’re doing. Follow the steps, document each one, and build up your case file as you need. Staying cool, organized, and ready with an answer for any questions you’ll face in the process of restoring your identity will help you see things through.
Once again, this is a good reminder that vigilance is the best defense against identity theft from happening in the first place. While there’s no absolute, sure-fire protection against it, there are several things you can do to lower the odds in your favor. And at the top of the list is keeping consistent tabs on what’s happening across your credit reports and accounts.
The post Top Signs of Identity Theft appeared first on McAfee Blog.
A good time to check if someone is using your identity is before it even happens.
One of identity theft’s several downsides is how people discover they’ve become a victim in the first place—by surprise. They go to rent an apartment, open a line of credit, or apply for financing, only to discover that their finances or reputation has taken a hit because of identity thief.
And those hits add up, particularly when you look at the dollars involved. In 2020, the Federal Trade Commission (FTC) reported $3.3 billion in financial losses from 4.7 million reported cases of fraud, a 45% increase over the year prior. Of those reports, identity theft was the leading fraud category, accounting for 29% of fraud incidents.
Plenty. Depending on the type and amount of information an identity thief gets their hands on, they can harm your finances and reputation in several ways, including:
Rather than ending up with a rude and potentially costly surprise of your own, you can get ahead of thieves by checking to see if someone is using your identity before it’s a problem or before it really takes root.
Major data breaches that expose personal information seem to hit the headlines with some regularity, not to mention the many, many more that don’t get national or international press coverage. Most recently we have the Neiman Marcus breach, where this major retailer alerted 4.6 million customers that “an unauthorized party obtained personal information associated with certain Neiman Marcus customers’ online accounts.”
And as it is with many such breaches, it took quite some time before the theft of information was discovered. Per Neiman Marcus, it’s believed that the breach occurred in May 2020 and only discovered in September of 2021. Potentially compromised information included:
Whether or not you have reason to suspect that your information got caught up in this recent large-scale breach, it serves as a good reminder that any time is the right time to check up on your identity. Acting now can save headaches, potentially big headaches, later.
Quite a bit of identity theft prevention begins with taking stock of the accounts and services you have in your name. This ranges anywhere from bank accounts to public utilities and from credit cards to loans, all of which contain varying degrees of personal information about you. With a sense of where your personal identity is being used, you can better look for instances where it’s being misused.
Ways you can spot for possible identity theft include:
If you stop receiving a bill that normally comes to you, such as a utility bill or for a department store credit card, that could be a sign that a thief has changed the mailing address and has potentially hijacked your identity.
This is rather straightforward, yet it reminds us how important it is to look at our statements closely. Charges that you didn’t ring up or that seem slightly higher than normal are a surefire sign that you should follow up with the bank or company involved and let them know of possible fraud.
In the U.S., you have annual access to free credit reports from the major credit reporting agencies. Not only will this give you a sense of your credit score, but it will also show the credit that’s open in your name, along with addresses associated with your identity. Spotting an account that you haven’t signed up for or seeing an address of a residence that you’re not renting are other common signs that your identity may have been compromised.
With the number of accounts many of us have these days, a credit monitoring service can help you stay on top of what’s happening in your name. Often offered through banks, credit unions, and even insurance providers, credit monitoring can alert you in several instances, including:
Overall, credit monitoring can act as another set of eyes for you and spot potential identity issues. Different services provide different levels of monitoring, so consider reviewing a few options to find the one that works best for you.
One like our own Identity Protection Service will monitor several types of personally identifiable information, alert you of potentially stolen personal info, and offer guided help to neutralize the threat—in addition to offering several preventative steps to help keep theft from happening in the first place. With this set up on your computers and smartphone you can stay in the know and address issues immediately.
Along with keeping an eye on what’s happening with your identity online and elsewhere, there are a few more things you can do to make it tougher for thieves to steal your identity.
Given all the banking and shopping we do on our computers and phones, installing and using comprehensive online protection software is a must these days. It puts several layers of security in place, such as creating complex passwords automatically, shielding credit card info from prying eyes, and protecting your privacy and data online by connecting with a VPN. In short, online protection software acts as a solid first line of defense.
As mentioned above, comprehensive online protection software often includes a password manager that can generate strong, unique passwords for each of your accounts and remember them for you. It’s extra protection that makes life a lot easier for you by managing all the accounts you’re juggling. Also, use MFA (multi-factor authentication) on the accounts that give you the option, which makes it harder for a thief to crack your accounts with a password alone.
Sensitive documents come in all forms. Top-of-the-line examples include things like tax returns, bank statements, and financial records. Yet there are also things like your phone and utility bills, statements from your doctor’s office, and offers that come to you via mail. Together, these things can contain personal information such as account numbers, your full Social Security Number, the last four digits of your Social Security Number (which can still be useful to thieves), and other information that may uniquely identify you. You’ll want to dispose of sensitive documents like these so that they can’t be harvested by hackers.
For physical documents, consider the low-cost investment of a paper shredder to help ensure they don’t fall into the wrong hands when you are done with them. (And let’s face it, they’re fun to use!) For digital documents, simply deleting a file is not enough – online protection software is a great resource that often includes a digital document shredder, designed to render the data practically unusable when you’re ready to trash the file.
Your Social Security Number is one of the most prized possessions a thief can run away with because it is so closely associated with you and things like your tax returns, employment, and so on. Keep it stored in a safe location rather than on your person or in your wallet. Likewise, be careful about giving out your SSN. While organizations like the IRS, your bank, and employer require it, there are other organizations who do not—but may ask for it anyway. (Doctor’s offices are a prime example.) If you get such a request, ask them what they intend to use it for and then ask if another form of identification will work instead.
Phishing attacks are one of the primary ways identity thieves steal personal information. Whether they come via a direct message, on social media, or through email, text, or phone calls, thieves use them to harvest your personal info by posing as a legitimate organization—such as in this recent IRS phishing scam. Phishing is a topic all unto itself, and you can check out this quick read to see how you can spot phishing scams and protect yourself from them.
Like any criminal, identity thieves do their dirtiest work in the shadows—quietly stealing money under your nose, or worse, as we outlined above. By shining a light on your identity and keeping regular track of what’s happening with it, you can spot unusual activity right away. Even the small stuff is important. A co-worker of mine once saw an incorrect address listed on his credit report. Turned out, that address was used to rack up several large charges at a retailer, which he was able to fix with the aid of the credit reporting agency and the retailer in question.
No doubt about it. Identity theft is indeed on the rise, and your best bet to avoid such a nasty surprise is to keep an eye on your digital identity the same way you keep an eye on your actual wallet.

There’s a lot of misinformation about Virtual Private Networks, what they do, and the security benefits they offer. For this article, I’d like to do some myth-busting about how a VPN actually works and why you should use one.
A VPN is an app that you install on your device to help keep your personal data safe as you browse the internet
You may have heard that VPN apps live on your device and allow you to connect to the internet securely. What that means is, when you turn your VPN app on, your device makes a secure connection to a specialized computer that routes internet traffic, called a VPN server. You also may have heard that your connection is “wrapped in an encrypted tunnel” which means your device and the server share a secure connection so only you can see what you’re doing on the internet.
Every internet connection (like your cable modem) is assigned a unique set of numbers called an IP address, which is tied to information such as geographic location, ISP, etc. A VPN replaces your actual IP address to make it look like you’ve connected to the internet from a different location: the physical location of the VPN server, rather than your real location. This is just one reason why so many people use VPNs. This can be handy when you want to hide from advertising trackers or protect your search history.
To change your IP address, you simply open your VPN app, select the server location you’d like to connect to, and you’re done. You’re now browsing with a new IP address. If you’d like to make sure your IP has changed, open up a browser and search for “What’s my IP address” and click on one of the results.
When to use a VPN really depends on what you want it for. For example, 39% of users understand public Wi-Fi is unsafe but still do sensitive things, like banking or shopping on public WiFi, so using a VPN when you’re at the airport, or a café is a great use case.
As I mentioned before, a lot of people use a VPN for privacy reasons, like stopping advertisers from tracking them. Searches you perform, or websites you visit won’t be trackable, which means you’ll be able to surprise your spouse with a vacation you researched and planned on a computer you both use. Targeted ads could spoil things if your spouse is bombarded with ads for plane tickets and hotels while they browse.
A VPN protects your search history through the secure connection you share. When you search for a website, or type a URL into your navigation bar, your device sends something called a DNS request, which translates the website into the IP address of the web server; this is how your browser can find the website and serve its content to you. By encrypting your DNS requests, a VPN can hide your search habits and history from those that might use that info as part of building a profile of you. This type of info could be used in a wide variety of ways, from legitimately serving targeted ads to nefarious social engineering.
A VPN can protect your identity by blocking online trackers from following you around the internet. With your VPN on, trackers will think all of your browsing is coming from a different device in a different location. This throws off the profile advertisers try to build because they think you’re someone else.
Another way a VPN can protect your identity is by preventing some types of hacking. Stopping attacks on public WiFi where a bad actor tries to get between you and the website you’re visiting, is just one way VPNs can help. It’s called a Man-in-the-Middle attack, but that’s a subject for another article.
No, a VPN cannot make you anonymous. They help secure what you’re doing, but your ISP still knows when you’re using the internet. They just can’t see what you’re doing, what sites you visit, or how long you’ve been on a site.
Private browsing modes can help protect your privacy, but they’re useful if you share a device with other people and you don’t want them to see your search history. You can read all about the differences in the article I wrote a little while ago.
Apple’s Private Relay is currently in Beta and will be available with an iCloud+ subscription for Safari users on iOS and macOS soon. Private Relay is similar to a VPN in that it changes your IP address so websites you visit can’t tell exactly where you are.
When you turn Private Relay on, your device connects to a server that sends your browsing data to a second server, before it travels through the internet. The reason for the double hop is that first server gives you a new IP address, to make you harder to track, while the second server hides that information from the website you’re browsing. The first server only knows your original IP address, while the second server only knows what you’re browsing, but not your IP.
Private Relay only works with Safari on iOS and macOS. Even if you are using an Apple device, a VPN is still a good idea because it will protect the information that your device sends outside of Safari.
If you’re already a McAfee Total Protection subscriber, you have access to unlimited VPN usage. Protect your personal information, like your banking information and credit cards, from prying eyes with McAfee Total Protection’s Secure VPN. If you haven’t already signed up, now’s the perfect time. McAfee Total Protection provides security for all your devices, giving you peace of mind while you shop, bank, and browse online.

If you have a tween or teen, you’ve likely heard a lot of excited chatter about Roblox. With a reported 150 million users, there’s a good chance your child has the Roblox site on their phone, tablet, PC, or Xbox. In fact, in 2020, Roblox estimated that over half of kids in the U.S. under 16 had used the forum. However, as with all digital destinations, the fun of Roblox is not without some safety concerns.
Roblox is an online gaming forum (not an app or game as one might assume) where users can create and share games or just play games. Kids can play Roblox games with friends they know or join games with unknown players. Roblox hosts an infinite number of games (about 20 million), which makes it a fun place to build and share creations, chat, and make friends. Game creators can also make significant money if their games take off.
A huge component of Roblox is its social network element that allows users to chat and have meetups. During quarantine, Roblox added its own private space for users to host virtual private birthday parties and social gatherings.
Like any site or app, Roblox is safe if you take the time to optimize parental controls (both in-forum and personal software), monitor your child’s use, and taking basic precautions you’re your child starts using the forum. Especially with kids drawn to gaming communities, it’s important to monitor conversations they can be having with anyone, anywhere.
Roblox security tip: Adjust settings to prohibit strangers’ from friending an account. Consider watching your child play a few games and how he or she interacts or wanders through the app. Pay close attention to the chat feature. Keep the conversation open, so your child feels comfortable sharing online concerns with you.
If you have your child’s login information, you can easily view their activity history in a few vulnerable areas including private and group chats, friends list, games played, games created, and items purchased. It’s also a good idea to make sure their birthdate is correct since Roblox automatically filters chats and game content for users under 13. Roblox has a separate login for parents of younger kids that allows you to go in and view all activities.
As always, the best way to keep your child safe on Roblox or any other site or app is to take every opportunity for open, honest conversation about personal choices and potential risks online. Oh, and sitting down to play their favorite games with them — is always the best seat in the house.

Over the past year, you may have seen the term ransomware popping up frequently. There’s good reason for that as ransomware is responsible for 21% of all cyberattacks, according to a new report. For enterprising hackers, this tactic has become standard operating procedure because it’s effective and organizations are willing to pay. But what does that mean for you and living a confident life online? Fortunately, there are a number of things individuals can do to avoid ransomware. But first, let’s start with the basics.
Ransomware is malware that employs encryption to hold a victim’s information at ransom. The hacker uses it to encrypt a user or organization’s critical data so that they cannot access files, databases, or applications. A ransom is then demanded to provide access. It is a growing threat, generating billions of dollars in payments to cybercriminals and inflicting significant damage and expenses for businesses and governmental organizations.
McAfee Labs counted a 60% increase in attacks from Q4 2019 to Q1 2020 in the United States alone. Unfortunately, the attacks targeting organizations also impact the consumers who buy from them, as the company’s data consists of its customers’ personal and financial information. That means your data if you’ve done business with the affected company. Fortunately, there are many ways you can protect yourself from ransomware attacks.
When a company is hit with a ransomware attack, they typically are quick to report the incident, even though a full analysis of what was affected and how extensive the breach may have been may take much longer. Once they have the necessary details they may reach out to their customers via email, through updates on their site, social media, or even the press to report what customer data may be at risk. Paying attention to official communications through these various channels is the best way to know if you’ve been affected by a ransomware attack.
The top ransomware infection vectors – a fancy term for the way you get ransomware on your device – are phishing and vulnerability exploits. Of these two, phishing is responsible for a full 41% of ransomware infections. Ironically, this is good news, because phishing is something we can learn to spot and avoid by educating ourselves about how scammers work. Before we get into specific tips, know that phishing can take the form of many types of communications including emails, texts, and voicemails. Also know that scammers are convincingly imitating some of the biggest brands in the world to get you to surrender your credentials or install malware on your device. With that in mind, here are several tips to avoid getting phished.
If you receive an email, call, or text asking you to download software or pay a certain amount of money, don’t click on anything or take any direct action from the message. Instead, go straight to the organization’s website. This will prevent you from downloading malicious content from phishing links or forking over money unnecessarily.
If someone sends you a message with a link, hover over the link without clicking on it. This will allow you to see a link preview. If the URL looks suspicious, don’t interact with it and delete the message altogether.
Instead of clicking on a link in an email or text message, it’s always best to check directly with the source to verify an offer, request, or link.
McAfee offers the free McAfee WebAdvisor, which can help identify malicious websites and suspect links that may be associated with phishing schemes.
If you do get ransomware, the story isn’t over. Below are 8 remediation tips that can help get your data back, along with your peace of mind.
If you get ransomware, you’ll want to immediately disconnect any infected devices from your networks to prevent the spread of it. This means you’ll be locked out of your files by ransomware and be unable to move the infected files. Therefore, it’s crucial that you always have backup copies of them, preferably in the cloud and on an external hard drive. This way, if you do get a ransomware infection, you can wipe your computer or device free and reinstall your files from backup. Backups protect your data, and you won’t be tempted to reward the malware authors by paying a ransom. Backups won’t prevent ransomware, but they can mitigate the risks.
If you discover that a data leak or a ransomware attack has compromised a company you’ve interacted with, act immediately and change your passwords for all your accounts. And while you’re at it, go the extra mile and create passwords that are seriously hard to crack with this next tip.
When updating your credentials, you should always ensure that your password is strong and unique. Many users utilize the same password or variations of it across all their accounts. Therefore, be sure to diversify your passcodes to ensure hackers cannot obtain access to all your accounts at once, should one password be compromised. You can also employ a password manager to keep track of your credentials and generate secure login keys.
Two or multi-factor authentication provides an extra layer of security, as it requires multiple forms of verification. For instance, you’ll be asked to verify your identity through another device, such as a phone. This reduces the risk of successful impersonation by hackers.
Be careful where you click. Don’t respond to emails and text messages from people you don’t know, and only download applications from trusted sources. This is important since malware authors often use social engineering to get you to install dangerous files. Using a security extension on your web browser is one way to browse more safely.
Avoid using public Wi-Fi networks, since many of them are not secure, and cybercriminals can snoop on your internet usage. Instead, consider installing a VPN, which provides you with a secure connection to the internet no matter where you go.
While it is often large organizations that fall prey to ransomware attacks, you can also be targeted by a ransomware campaign. If this happens, don’t pay the ransom. Although you may feel that this is the only way to get your encrypted files back, there is no guarantee that the ransomware developers will send a decryption tool once they receive the payment. Paying the ransom also contributes to the development of more ransomware families, so it’s best to hold off on making any payments. Thankfully there are free resources devoted to helping you like McAfee’s No More Ransomware initiative McAfee, along with other organizations, created www.nomoreransom.org/ to educate the public about ransomware and, more importantly, to provide decryption tools to help people recover files that have been locked by ransomware. On the site you’ll find decryption tools for many types of ransomware, including the Shade ransomware.
Adding an extra layer of security with a solution such as McAfee® Total Protection, which includes Ransom Guard, can help protect your devices from these cyber threats. In addition, make sure you update your devices’ software (including security software!) early and often, as patches for flaws are typically included in each update. Comprehensive security solutions also include many of the tools we mentioned above and are simply the easiest way to ensure digital wellness online.

Imagine you’re driving down a highway to get to work. There are other cars on the road, but by and large everyone is moving smoothly at a crisp, legal speed limit. Then, as you approach an entry ramp, more cars join. And then more, and more, and more until all of the sudden traffic has slowed to a crawl. This illustrates a DDoS attack.
DDoS stands for Distributed Denial of Service, and it’s a method where cybercriminals flood a network with so much malicious traffic that it cannot operate or communicate as it normally would. This causes the site’s normal traffic, also known as legitimate packets, to come to a halt. DDoS is a simple, effective and powerful technique that’s fueled by insecure devices and poor digital habits. Luckily, with a few easy tweaks to your everyday habits, you can safeguard your personal devices against DDoS attacks.
The expansion of 5G, proliferation of IoT and smart devices, and shift of more industries moving their operations online have presented new opportunities for DDoS attacks. Cybercriminals are taking advantage, and 2020 saw two of the largest DDoS offensives ever recorded. In 2020, ambitious attacks were launched on Amazon and Google. There is no target too big for cybercriminals.
DDoS attacks are one of the more troubling areas in cybersecurity, because they’re incredibly difficult to prevent and mitigate.. Preventing these attacks is particularly difficult because malicious traffic isn’t coming from a single source. There are an estimated 12.5 million devices that are vulnerable to being recruited by a DDoS attacker.
DDoS attacks are fairly simple to create. All it takes are two devices that coordinate to send fake traffic to a server or website. That’s it. Your laptop and your phone, for example, could be programmed to form their own DDoS network (sometimes referred to as a botnet, more below). However, even if two devices dedicate all of their processing power in an attack, it still isn’t enough to take down a website or server. Hundreds and thousands of coordinated devices are required to take down an entire service provider.
To amass a network of that size, cybercriminals create what’s known as a “botnet,” a network of compromised devices that coordinate to achieve a particular task. Botnets don’t always have to be used in a DDoS attack, nor does a DDoS have to have a botnet to work, but more often than not they go together like Bonnie and Clyde. Cybercriminals create botnets through fairly typical means: tricking people into downloading malicious files and spreading malware.
But malware isn’t the only means of recruiting devices. Because a good deal of companies and consumers practice poor password habits, malicious actors can scan the internet for connected devices with known factory credentials or easy-to-guess passwords (“password,” for example). Once logged in, cybercriminals can easily infect and recruit the device into their cyber army.
These recruited cyber armies can lie dormant until they’re given orders. This is where a specialized server called a command and control server (typically abbreviated as a “C2”) comes into play. When instructed, cybercriminals will order a C2 server to issue instructions to compromised devices. Those devices will then use a portion of their processing power to send fake traffic to a targeted server or website and, voila! That’s how a DDoS attack is launched.
DDoS attacks are usually successful because of their distributed nature, and the difficulty in discerning between legitimate users and fake traffic. They do not, however, constitute a breach. This is because DDoS attacks overwhelm a target to knock it offline — not to steal from it. Usually DDoS attacks will be deployed as a means of retaliation against a company or service, often for political reasons. Sometimes, however, cybercriminals will use DDoS attacks as a smokescreen for more serious compromises that may eventually lead to a full-blown breach.
DDoS attacks are only possible because devices can be easily compromised. Here are three ways you can prevent your devices from participating in a DDoS attack:
Now that you know what a DDoS attack is and how to protect against it, you’re better equipped to keep your personal devices and safe and secure.

Seems like the internet follows us wherever we go nowadays, whether it tags along via a smartphone, laptop, tablet, a wearable, or some combination of them all. Yet there’s something else that follows us around as well—our PII, a growing body of “personally identifiable information” that we create while banking, shopping, and simply browsing the internet. And no doubt about it, our PII is terrifically valuable.
What makes it so valuable? It’s no exaggeration to say that your PII is the key to your digital life, along with your financial and civic life as well. Aside from using it to create accounts and logins, it’s further tied to everything from your bank accounts and credit cards to your driver’s license and your tax refund.
Needless to say, your PII is something that needs protecting, so let’s take a look at several ways you can do just that.
What is PII? It’s information about you that others can use to identify you either directly or indirectly. Thus, that info could identify you on its own, or it could identify you when it’s linked to other identifiers, like the ones associated with the devices, apps, tools, and protocols you use.
A prime example of direct PII is your tax ID number because it’s unique and directly associated with your name. Further instances include your facial image to unlock your smartphone, your medical records, your finances, and your phone number because each of these can be easily linked back to you.
Then there are those indirect pieces of PII that act as helpers. While they may not identify you on their own, a few of them can when they’re added together. These helpers include things like internet protocol addresses, the unique device ID of your smartphone, or other identifiers such as radio frequency identification tags.
You can also find pieces of your PII in the accounts you use, like your Google to Apple IDs, which can be linked to your name, your email address, and the apps you have. You’ll also find it in the apps you use. For example, there’s PII in the app you use to map your walks and runs, because the combination of your smartphone’s unique device ID and GPS tracking can be used in conjunction with other information to identify who you are, not to mention where you typically like to do your 5k hill days. The same goes for messenger apps, which can collect how you interact with others, how often you use the app and your location information based on your IP address, GPS information, or both.
In all, there’s a cloud of PII that follows us around as we go about our day online. Some wisps of that cloud are more personally identifying than others. Yet gather enough of it and PII can create a high-resolution snapshot of you—who you are, what you’re doing when you’re doing it, and even where you’re doing it too—particularly if it gets into the wrong hands.
Remember Pig-Pen, the character straight from the old funny pages of Charles Schultz’s Charlie Brown? He’s hard to forget with that ever-present cloud of dust following him around. Charlie Brown once said, “He may be carrying the soil that trod upon by Solomon or Nebuchadnezzar or Genghis Khan!” It’s the same with us and our PII, except the cloud surrounding us, isn’t the dust of kings and conquerors, they’re motes of digital information that are of tremendously high value to crooks and bad actors—whether for purposes of identity theft or invasion of privacy.
With all PII we create and share on the internet, that calls for protecting it. Otherwise, our PII could fall into the hands of a hacker or identity thief and end up getting abused, in potentially painful and costly ways.
Here are several things you can do to help ensure that what’s private stays that way:
Square One is to protect your devices with comprehensive online protection software. This will defend you against the latest virus, malware, spyware, and ransomware attacks plus further protect your privacy and identity. In addition to this, it can also provide strong password protection by generating and automatically storing complex passwords to keep your credentials safer from hackers and crooks who may try to force their way into your accounts.
Further, security software can also include a firewall that blocks unwanted traffic from entering your home network, such as an attacker poking around for network vulnerabilities so that they can “break-in” to your computer and steal information.
Also known as a virtual private network, a VPN helps protect your vital PII and other data with bank-grade encryption. The VPN encrypts your internet connection to keep your online activity private on any network, even public networks. Using a public network without a VPN can increase your cybersecurity risk because others on the network can potentially spy on your browsing and activity.
If you’re new to the notion of using a VPN, check out this article on VPNs and how to choose one so that you can get the best protection and privacy possible.
In the U.S., the Social Security Number (SSN) is one of the most prized pieces of PII as it unlocks the door to employment, finances, and much more. First up, keep a close grip on it. Literally. Store your card in a secure location. Not your purse or wallet.
Certain businesses and medical practices may ask you for your SSN for billing purposes and the like. You don’t have to provide it (although some businesses could refuse service if you don’t), and you can always ask if they will accept some alternative form of information. However, there are a handful of instances where an SSN is a requirement. These include:
Be aware that hackers often get a hold of SSNs because the organization holding that information gets hacked or compromised itself. Minimizing how often you provide your SSN can offer an extra degree of protection.
Protecting your files with encryption is a core concept in data and information security, and thus it’s a powerful way to protect your PII. It involves transforming data or information into code that requires a digital key to access it in its original, unencrypted format. For example, McAfee Total Protection includes File Lock, which is our file encryption feature that lets you lock important files in secure digital vaults on your device.
Additionally, you can also delete sensitive files with an application such as McAfee Shredder, which securely deletes files so that thieves can’t access them. (Quick fact: deleting files in your trash doesn’t actually delete them in the truest sense. They’re still there until they’re “shredded” or otherwise overwritten such that they can’t be restored.)
Which Marvel Universe superhero are you? Does it really matter? After all, such quizzes and social media posts are often grifting pieces of your PII in a seemingly playful way. While you’re not giving up your SSN, you may be giving up things like your birthday, your pet’s name, your first car … things that people often use to compose their passwords or use as answers to common security questions on banking and financial sites. The one way to pass this kind of quiz is not to take it!
A far more direct form of separating you from your PII are phishing attacks. Posing as emails from known or trusted brands, financial institutions, or even a friend or family member a cybercrook’s phishing attack will attempt to trick you into sharing important information like your logins, account numbers, credit card numbers, and so on under the guise of providing customer service.
How do you spot such emails? Well, it’s getting a little tougher nowadays because scammers are getting more sophisticated and can make their phishing emails look nearly legitimate. However, there are several ways you can spot a phishing email and phony web pages as outlined here.
Comprehensive security offers another layer of prevention, in this case by offering browser protection like our own Web Advisor, which will alert you in the event you come across suspicious links and downloads that can steal your PII or otherwise expose you to attacks.
With social engineering attacks that deceive victims by posing as people the victim knows and the way we can sometimes overshare a little too much about our lives, you can see why a social media profile is a potential goldmine for cybercriminals.
Two things you can do to help protect your PII from being at risk via social media: one, think twice about what PII you might be sharing in that post or photo—like the location of your child’s school or the license plate on your car; two, set your profile to private so that only friends can see it. Review your privacy settings regularly to keep your profile information out of the public eye. And remember, nothing is 100% private on the internet. Never post anything you wouldn’t want to see shared.
The “S” stands for secure. Any time you are shopping, banking, or sharing any kind of PII, look for “https” at the start of the web address. Some browsers will also indicate HTTP by showing a small “lock” icon. Doing otherwise on plain HTTP sites exposes your PII for anyone who cares to monitor that site for unsecured connections.
By locking your devices, you protect yourself that much better from PII and data theft in the event your device is lost, stolen, or even left unattended for a short stretch. Use your password, PIN, facial recognition, thumbprint ID, what have you. Just lock your stuff. In the case of your smartphones, read up on how you can locate your phone or even wipe it remotely if you need to. Apple provides iOS users with a step-by-step guide for remotely wiping devices, and Google offers up a guide for Android users as well.
Theft of your PII can of course lead to credit cards and other accounts being opened falsely in your name. What’s more, it can sometimes be some time before you even become aware of it, until perhaps your credit score takes a hit or a bill collector comes calling. By checking your credit, you can address any issues that come up, as companies typically have a clear-cut process for contesting any fraud. You can get a free credit report in the U.S. via the Federal Trade Commission (FTC) and likewise, other nations like the UK have similar free offerings as well.
Consider identity theft protection as well. A strong identity theft protection package pairs well with keeping track of your credit and offers cyber monitoring that scans the dark web to detect for misuse of your PII. With our identity protection service, we help relieve the burden of identity theft if the unfortunate happens to you with $1M coverage for lawyer fees, travel expenses, lost wages, and more.

All the kids are doing it, and so can you.
If you haven’t hopped onto a video chat with the family yet, the holidays are a great time to give it a whirl. While there are plenty of apps and services out there for video chatting, I put together a quick list of the more no-nonsense options.
Broadly speaking, I selected video chatting apps that are free, relatively straightforward, and possibly something you already have on your smartphone, tablet, or computer. From there, I also offer up some advice that can keep you and your family safe while you chat. Let’s take a look …
One of the easiest ways to hop onto a video chat is with your smartphone or tablet. They can save you a bit of configuring and fiddling around with settings because these devices have cameras, microphones, and video chat apps already built in. In that way, they’re optimized for video chat, so using one of them is practically “point and shoot.”
Depending on what smartphone or tablet you have, you have a couple of leading options:
Pre-installed on iPhones and iPads, FaceTime can connect up to 32 people on iOS and Mac OS devices at one time. That way, if you want to chat with a few family members at once, you can have plenty of people join in. Note that only iOS and Mac OS devices can use FaceTime, so the person you want to chat with will need FaceTime on a iOS or Mac OS device as well. Connections are quite simple. In fact, as simple as making a phone call. You can start a FaceTime call with a tap of family members in your contact list. Your device does the rest.
Google Duo is a voice chat app much akin to FaceTime that’s found on plenty of Android phones and tablets. However, it differs from FaceTime because it’s available for multiple platforms. For example, there’s a Google Duo app for iPhones, so if your grandkids have iPhones, they can install the Google Duo on their iPhones and have a chat with you on your Android phone.
Also, you can use Google Duo on a web browser without an app by clicking here. That’s a great option if you have a camera-ready laptop or computer—which we’ll talk about more next.) Google Duo also features “Family Mode” where you can put on masks and make doodles on the screen if you’re signed in with a Google account.
If you don’t have a smartphone or tablet, there are still plenty of options that are free and relatively easy as well.
For starters, you’ll need a laptop or computer with a microphone and camera, which is more or less standard in laptops today. If your laptop or computer doesn’t have that combo already, not to worry. There are plenty of moderately priced web cameras that include a microphone. I suggest getting one with a physical lens cap. That way it always protects your privacy. Likewise, you can always disconnect yours when it’s not in use.
With that, here are a few options for video chatting on your computer:
Originally aimed at a business audience, families and schools quickly latched on to Zoom for its ease of use at the start of the pandemic. Zoom offers unlimited time and unlimited calls for one-to-one meetings yet has a 40-minute limit once there are more than two devices connected. While there’s an app available, I recommend that you set up a free account and run it through a browser window. That way, you don’t have to deal with an install and you’ll always have the latest security protocols in play.
Skype from Microsoft has been around for a long time, getting its start back in the early 2000’s as a voice and text chatting app. Today, it comes standard on Windows PCs and supports apps for all kinds of tablets and smartphones too. Up to 50 people can join, which is of course plenty. If you want to create a video chat without an account, you can simply visit this page and start an instant video chat with a click. That’ll give you a link that you can copy and share with your family. And when they click on that link, you’ll all be connected.
Free to anyone with a free Google Gmail account, you can use Google Meet just by clicking its icon from your Google apps menu or by visiting https://meet.google.com/. Originally designed for businesses, governments, and schools, this premium product is now available to all. Some nice features include the ability to schedule a meeting with your family using Google Calendar and additional security features that help make sure your call is private. Like Zoom and Skype, it can run in the window of your browser, so there’s no app to download and install.
As I mentioned above, there’s practically setup when it comes to running a video call on your smartphone or tablet, as they’re already configured for video. Computers, however, may take a little more effort.
The first thing is to make sure that your microphone, speakers, and camera are all set up and ready to go. If you have a Windows computer, you can check out this quick article to get your audio set up and this article for setting up your camera. For Macs, check out this article for audio and this article for video.
From there, you can log into your video chat app or service of choice and give your audio and video a test just to make sure everything is a go. You can do this before you make a call by starting the app as you normally would and then clicking on the menu item for “Settings.” Each app handles it a little differently, yet the interface should show you if it detects your camera, microphone, and speakers. Once you’re set up, you likely won’t have to go back in and do it again.
Now, it’s time to think like a movie director. As you might think, the camera angle and lighting in your room make all the difference on a video chat.
In a way, the camera is the way you’ll make eye contact with your family. Set the camera or hold your device so that it’s at eye level with you. That way, it’ll appear like you’re making eye contact with them. Few things feel stranger on a video chat than a camera angle that appears to have you looking down at them (and with them looking up your nose in return).
As for lighting, avoid sitting with a light source behind you. The camera will adjust itself to the light source instead of you, putting your face in the dark. Instead, look to have a light source that’s in front and a bit off to the side from you. That’ll light your face without washing out your face in harsh light. Likewise, if you’re sitting in front of a computer monitor while you’re chatting, see if you can lower the brightness on the monitor. That’ll keep your video looking great as well.
Once you’re all set up, here are a few things that will help keep your calls private and secure.
If you’re initiating the chat, be sure to create a password that that uninvited parties can’t join the call. Also, don’t be shy about asking your family members to use a password on the calls they initiate. It’s pretty much a standard practice nowadays.
Many services, like Zoom, allow people to join a video chat by clicking a link. As with any link that’s sent to you, be sure that it’s legitimate. Confirm the link with the family member who sent it, particularly if you weren’t expecting one.
Likewise, make sure that you’re using comprehensive security software that protects you from scam emails and links, plus block links that could send you to sketchy websites. That way, if you do get sent a bogus invite link from a scammer, you’ll be protected.
When you click a link to join a video call from your computer, it will open a new browser tab that will prompt you to join the call. Often, there will be an option to “join using the app,” which your browser will automatically download if you click that option. However, the easiest way to join is by clicking the option to “join using my browser.” In addition to being a no-fuss option, it also means one less app on your device to keep current.
Aside from giving you the latest features and functionality, updates also often include essential security improvements. Set your computer to update itself automatically and consider using security software that will scan for vulnerabilities and install updates automatically as needed.
With the holidays upon us and the and New Year on the horizon, now’s a great time to give video chatting a try. As with any new app you try, do a little research of your own before you download it. Check out the news reviews to see if it’s right for you or if there have been any security concerns.
I hope this overview gives you a great start and that it becomes just one more of the many ways you keep in touch, whether during the holidays or year ’round.

At Black Hat USA 2020, Trend Micro presented two important talks on vulnerabilities in Industrial IoT (IIoT). The first discussed weaknesses in proprietary languages used by industrial robots, and the second talked about vulnerabilities in protocol gateways. Any organization using robots, and any organization running a multi-vendor OT environment, should be aware of these attack surfaces. Here is a summary of the key points from each talk.
Rogue Automation
Presented at Black Hat, Wednesday, August 5. https://www.blackhat.com/us-20/briefings/schedule/index.html#otrazor-static-code-analysis-for-vulnerability-discovery-in-industrial-automation-scripts-19523 and the corresponding research paper is available at https://www.trendmicro.com/vinfo/us/security/news/internet-of-things/unveiling-the-hidden-risks-of-industrial-automation-programming
Industrial robots contain powerful, fully capable computers. Unlike most contemporary computers, though, industrial robots lack basic information security capabilities. First, at the architectural level, they lack any mechanism to isolate certain instructions or memory. That is, any program can alter any piece of storage, or run any instruction. In traditional mainframes, no application could access, change, or run any code in another application or in the operating system. Even smartphone operating systems have privilege separation. An application cannot access a smartphone’s camera, for instance, without being specifically permitted to do so. Industrial robots allow any code to read, access, modify, or run any device connected to the system, including the clock. That eliminates data integrity in industrial robots and invalidates any audit of malfunctions; debugging becomes exceptionally difficult.
Industrial robots do not use conventional programming languages, like C or Python. Instead, each manufacturer provides its own proprietary programming language. That means a specialist using one industrial robot cannot use another vendor’s machine without training. There are no common information security tools for code validation, since vendors do not develop products for fragmented markets. These languages describe programs telling the robot how to move. They also support reading and writing data, analyzing and modifying files, opening and closing input/output devices, getting and sending information over a network, and accessing and changing status indicators on connected sensors. Once a program starts to run on an industrial robot, it can do anything any fully functional computer can do, without any security controls at all. Contemporary industrial robots do not have any countermeasures against this threat.
Most industrial robot owners do not write their own programs. The supply chain for industrial robot programs involves many third-party actors. See Figure 1 below for a simplified diagram. In each community, users of a particular vendor’s languages share code informally, and rely on user’s groups for hints and tips to solve common tasks. These forums rarely discuss security measures. Many organizations hire third-party contractors to implement particular processes, but there are no security certifications relevant to these proprietary languages. Most programmers learned their trade in an air-gapped world, and still rely on a perimeter which separates the safe users and code inside from the untrusted users and code outside. The languages offer no code scanners to identify potential weaknesses, such as not validating inputs, modifying system services, altering device state, or replacing system functions. The machines do not have a software asset management capability, so knowing where the components of a running program originated from is uncertain.
Figure 1: The Supply Chain for Industrial Robot Programming
All is not lost – not quite. In the short term, Trend Micro Research has developed a static code analysis tool called OTRazor, which examines robotic code for unsafe code patterns. This was demonstrated during our session at Black Hat.
Over time, vendors will have to introduce basic security checks, such as authentication, authorization, data integrity, and data confidentiality. The vendors will also have to introduce architectural restrictions – for instance, an application should be able to read the clock but not change it.. Applications should not be able to modify system files, programs, or data, nor should they be able to modify other applications. These changes will take years to arrive in the market, however. Until then, CISOs should audit industrial robot programs for vulnerabilities, and segment networks including industrial robots, and apply baseline security programs, as they do now, for both internally developed and procured software.
Protocol Gateway Vulnerabilities
Presented at Black Hat, Wednesday, August 5, https://www.blackhat.com/us-20/briefings/schedule/index.html#industrial-protocol-gateways-under-analysis-20632, with the corresponding research paper available here: https://www.trendmicro.com/vinfo/us/security/news/internet-of-things/lost-in-translation-when-industrial-protocol-translation-goes-wrong.
Industry 4.0 leverages the power of automation alongside the rich layer of software process control tools, particularly Enterprise Resource Planning (ERP), and its bigger cousin, Supply Chain Management (SCM). By bringing together dynamic industrial process control with hyper-efficient “just-in-time” resource scheduling, manufacturers can achieve minimum cost, minimum delay, and optimal production. But these integration projects require that IIoT devices speak with other technology, including IIoT from other manufacturers and legacy equipment. Since each equipment or device may have their own communication protocol, Industry 4.0 relies heavily on protocol converters.
Protocol converters are simple, highly efficient, low-cost devices that translate one protocol into another. Protocol converters are ubiquitous, but they lack any basic security capabilities – authentication, authorization, data integrity or data confidentiality – and they sit right in the middle of the OT network. Attackers can subvert protocol converters to hijack the communication or change configuration. An attacker can disable a safety thresholds, generate a denial of service attack, and misdirect an attached piece of equipment.
In the course of this research, we found nine vulnerabilities and are working with vendors to remediate the issues. Through our TXOne subsidiary, we are developing rules and intelligence specifically for IIoT message traffic, which are then embedded in our current network security offerings, providing administrators with better visibility and the ability to enforce security policies in their OT networks.
Protocol converters present a broad attack surface, as they have limited native information security capabilities. They don’t validate senders or receivers, nor do they scan or verify message contents. Due to their crucial position in the middle of the OT network, they are an exceptionally appealing target for malicious actors. Organizations using protocol converters – especially those on the way to Industry 4.0 – must address these weak but critical components of their evolving infrastructure.
