The Era of Cyber Threat Intelligence Sharing

By The Hacker News
We spent forty years defending ourselves as individuals. Trying to outsmart cybercriminals, outpower them, and when all our efforts failed, only then we considered banding together with our peers to outnumber them. Cybercriminals don't reinvent themselves each time. Their resources are limited, and they have a limited budget. Therefore they use playbooks to attack many people. Meaning most of

Beware: Cybercriminals Launch New BrasDex Android Trojan Targeting Brazilian Banking Users

By Ravie Lakshmanan
The threat actors behind the Windows banking malware known as Casbaneiro has been attributed as behind a novel Android trojan called BrasDex that has been observed targeting Brazilian users as part of an ongoing multi-platform campaign. BrasDex features a "complex keylogging system designed to abuse Accessibility Services to extract credentials specifically from a set of Brazilian targeted apps,

Secure Email Threat Defense: Providing critical insight into business risk

By Kevin Potts

Attackers specifically craft business email compromise (BEC) and phishing emails using a combination of malicious techniques, expertly selected from an ever-evolving bag of tricks. They’ll use these techniques to impersonate a person or business that’s well-known to the targeted recipient and hide their true intentions, while attempting to avoid detection by security controls.

As a result of the requisite expertise needed to combat these complex attacks, email security has traditionally been siloed away in disparate teams and security controls. Practitioners are buried under an ever-growing pile of RFCs, requiring extensive domain-specific knowledge, unending vigilance, and meticulous manual interventions, such as tweaking trust levels and cultivating allow/block lists with IPs, domains, senders, and vendors.

Cisco Secure Email Threat Defense is leading the industry forward with a major shift, elevating email security into a new era; where administration will consist of merely associating specific business risks with the appropriate due diligence response required to remediate against them.

Email Threat Defense has introduced a new Threat Profile that provides the customer with deep insights into the specific business risks of individual email threats and the confidence to act quickly. This new visualization is powered by a new patent-pending threat detection engine. This engine leverages intelligence distilled from Talos global-scale threat research across a massive volume of email traffic into machine learning, behavioral modeling, and natural language understanding.

The detection engine granularly identifies specific underlying threat techniques utilized in the message by the attacker. The identified techniques provide the full context of the threat message as the supporting foundation for the engine to determine threat categorization and the specific risk to the business. These malicious Techniques, together with the threat category and specific business risk, are used to populate the Threat Profile.

Each message’s Threat Profile is identified in real-time, automatically remediated per policy, and surfaced directly to the operator in the message detail views, providing deep contextual insights into the attacker’s intent and the associated risks to the business. As part of a larger Extended Detection and Response (XDR) strategy, the actionable intelligence in Email Threat Defense is integrated with the wider enterprise orchestration of security controls via SecureX, easing the operational burden by decreasing your mean time to remediation (MTTR).

Email Threat Defense delivers a distinct understanding of malicious messages, the most vulnerable targets within the organization, and the most effective means of protecting them from phishing, scams, and BEC attacks. With a clean design and core focus on simplifying administration, Email Threat Defense deploys in minutes to strengthen protection of your existing Microsoft 365 Exchange Online platform against the most advanced email threats.

Researchers Uncover MirrorFace Cyber Attacks Targeting Japanese Political Entities

By Ravie Lakshmanan
A Chinese-speaking advanced persistent threat (APT) actor codenamed MirrorFace has been attributed to a spear-phishing campaign targeting Japanese political establishments. The activity, dubbed Operation LiberalFace by ESET, specifically focused on members of an unnamed political party in the nation with the goal of delivering an implant called LODEINFO and a hitherto unseen credential stealer

Cisco Secure Cloud Analytics – What’s New

By Claudio Lener

Nowadays, “cybersecurity” is the buzzword du jour, infiltrating every organization, invited or not. Furthermore, this is the case around the world, where an increasing proportion of all services now have an online presence, prompting businesses to reconsider the security of their systems. This, however, is not news to Cisco, as we anticipated it and were prepared to serve and assist clients worldwide.

Secure Cloud Analytics, part of the Cisco Threat, Detection, and Response (TD&R) portfolio, is an industry-leading tool for tackling core Network Detection and Response (NDR) use cases. These workflows focus primarily on threat detection and how security teams may recognize the most critical issues around hunting and forensic investigations to improve their mean-time-to-respond.

Over the last year, the product team worked tirelessly to strengthen the NDR offering. New telemetry sources, more advanced detections, and observations supplement the context of essential infrastructure aspects as well as usability and interoperability improvements. Additionally, the long-awaited solution Cisco Telemetry Broker is now available, providing a richer SecOps experience across the product.

MITRE ATT&CK framework alerting capabilities

As part of our innovation story on alerting capabilities, Secure Cloud Analytics now features new detections tied to the MITRE ATT&CK framework such as Worm Propagation, Suspicious User Agent, and Azure OAuth Bypass.

Additionally, various new roles and observations were added to the Secure Cloud Analytics to improve and change user alerts, that are foundational pieces of our detections. Alerts now include a direct link to AWS’ assets and their VPC, as well as direct access to Azure Security Groups, enabling further investigation capabilities through simplified workflows. In addition, the Public Cloud Providers are now included in coverage reports that provide a gap analysis to determine which accounts are covered. Alert Details offers new device information, such as host names, subnets, and role metrics that emphasize detection techniques. To better configure alerts, we are adding telemetry to gain contextual reference on their priority. Furthermore, the ingest process has grown more robust due to data from the Talos intelligence feed and ISE.

NDR: A Force Multiplier to Cisco XDR Strategy

The highly anticipated SecureX integration is now available in a single click, with no API credentials required and smooth interaction between the two platforms. Most importantly, Secure Cloud Analytics alerts may now be configured to automatically publish as incidents to the SecureX Incident Manager. The Talos Intelligence Watchlist Hits Alert is on by default due to its prominence among the many alert types.

Among other enhancements to graphs and visualizations, the Encrypted Traffic widget allows for an hourly breakdown of data. Simultaneously, the Device Report contains traffic data for a specific timestamp, which may be downloaded as a CSV. Furthermore, the Event Viewer now displays bi-directional session traffic to provide even more context to Secure Cloud Analytics flows, as well as additional columns to help with telemetry log comprehension: Cloud Account, Cloud Region, Cloud VPC, Sensor and Exporter.

New Sensor Data to Quickly Detect and Hunt Threats

On-premises sensors now provide additional telemetry on the overview page and a dedicated page where users can look further into the telemetry flowing through them in Sensor Health. To optimize the Secure Cloud Analytics deployment and improve the user experience, sensors may now be deleted from the interface.

Regarding telemetry, Cisco Telemetry Broker can now serve as a sensor in Secure Cloud Analytics, so users can identify and respond to threats faster with additional context sent to Secure Cloud Analytics. In addition, there will soon be support for other telemetry types besides IPFIX and NetFlow.

As we can see from the vast number of new additions to Secure Cloud Analytics, the product team has been working hard to understand the latest market trends, listen to the customers’ requests, and build one of the finest SaaS products in the NDR industry segment. The efforts strongly underline how Secure Cloud Analytics can solve some of the most important challenges in the NDR space around visibility, fidelity of alerts and deployment complexity by providing a cloud hosted platform that can offer insights on-premise and on cloud environments simultaneously from the same dashboard. Learn more about new features that allow Secure Cloud Analytics to detect, analyze, and respond to the most critical dangers to their company much more quickly.

Researchers Uncover Darknet Service Allowing Hackers to Trojanize Legit Android Apps

By Ravie Lakshmanan
Researchers have shed light on a new hybrid malware campaign targeting both Android and Windows operating systems in a bid to expand its pool of victims. The attacks entail the use of different malware such as ERMAC, Erbium, Aurora, and Laplas, according to a ThreatFabric report shared with The Hacker News. "This campaign resulted in thousands of victims," the Dutch cybersecurity company said,

Explorations in the spam folder–Holiday Edition

By Ben Nahorney

Watch ThreatWise TV: Explorations in the spam folder

The spam folder: that dark and disregarded corner of every email account, full of too-good-to-be-true offers, unexpected shipments, and supposedly free giveaways.

You’re right to ignore this folder; few good things come from exploring it. But every once in a while one of these misleading, and sometimes malicious, emails manages to evade the filters that normally siphon them off, landing them in your inbox instead.

Fortunately, it’s easy enough to spot these emails if you know what to look for. We’ve investigated this folder once before, showcasing a variety of scams. With the holiday season in full swing, we thought this would be a good time to revisit how scammers are trying to trick unsuspecting users.

The holiday season is traditionally a time when this type of activity increases, and this year is no different. According to research published by credit reporting agency TransUnion, the average daily number of suspected digital fraud attempts was up 82 percent globally between Thanksgiving and Cyber Monday (Nov 24–Nov 28) compared to the rest of the year (Jan 1–Nov 23) and 127 percent higher for transactions originating in the US.

This level of activity makes it all the more important to be aware of these scams. With that in mind, let’s dive into the spam folder to get a picture of the types of campaigns currently circulating.

A word of caution

While much of the spam circulating is innocuous, many emails are phishing attempts, and some are indeed malicious. To explore these scams, we used a dedicated computer, segmented from the rest of the network, and leveraged Cisco Secure Malware Analytics to safely open the emails before clicking on links or opening attachments. The point being, we do not recommend doing this at home.

10 questions for an amazing gift

By far, the largest category of spam we saw were surveys scams. According to these emails, if you fill out a simple survey you’ll receive “exclusive offers” such as gift cards, smartphones, smart watches, power drills, or even pots and pans.

Image 1 – Survey scam emails

There are even some campaigns that specifically target the holiday shopping season.

Image 2 – Holiday-themed survey scams

Clicking the links in these emails takes the recipient to sites where they are asked to fill out a survey.

Image 3 – Survey landing pages

These pages often include fake testimonials that say how easy the survey is and what they did with their free gift.

Image 4 – Fake testimonials

The surveys are straightforward, comprising 10-20 simple questions that cover demographic information and shopping habits.

Image 5 – Survey questions

After the survey is completed, these sites offer the choice of a handful of rewards. All the recipient must do is pay for shipping. They are then brought to a page where they can fill out shipping and payment information, and the reward is supposedly shipped.

Image 6 – Steps to receive a “special deal”

However, the attempts to make payment often appear to fail, or the recipient is informed that the prize is no longer available.

Image 7 – Failed attempts to claim rewards

An unsuspecting user may simply give up at this point, disappointed that they won’t be getting their free gift. What they may not be aware of, is that they have just given their credit card details away in a phishing scam.

In their 2021 Internet Crime Report, the Internet Crime Complaint Center (IC3) said that Non-Payment / Non-Delivery scams such as these led to more than $337 million in losses, up from $265 million in 2020. Credit card fraud amounted to $172 million in 2021 and has been climbing continuously at a conservative rate of 15-20 percent since 2019.

According to Cisco Umbrella, many of the sites asking for credit card details are known phishing sites, or worse, host malware.

Your package is in route

Another topic that we covered the last time we explored these types of scams was package delivery spam. These continue to circulate today. There are a variety of shipping companies impersonated in these campaigns, and some generic ones as well.

Image 9 – Package scam emails

Many of these campaigns claim that a package could not be delivered. If the recipient clicks on a link in an email, they’re brought to a web page that explains that there are outstanding delivery fees that need to be paid.

Image 10 – Steps in package delivery phishing scam

The recipient is further enticed by suggestions that the package contains a big-ticket item, such as an iPhone or iPad Pro. All the recipient is required to do is enter their credit card details to cover the shipping.

Image 11 – Credit card entry steps in package delivery phishing scam

While no outright malicious activity was detected while examining these emails in Secure Malware Analytics, several suspicious behaviors were flagged. Chances are the bad actors behind these campaigns are phishing for credit card details.

Image 12 – Indications of phishing activity

Plain-text messages

Sometimes the simplest approaches can work just as well as the flashiest. This certainly holds true with spam campaigns, given the prominence of plain-text messages.

Image 13 – Plain-text spam email examples

The topics covered in such emails run the gamut, including medical cures, 419 scams, romance and dating, pharmaceuticals, weight loss, and many of the scam types we’ve already covered. Many of these link to phishing sites, though some attempt to establish a dialog with the recipient, tricking them into sending the scammers money.

The IC3 report says that victims of confidence fraud and romance scams lost $956 million collectively, which is up from $600 million in 2020. Healthcare fraud, such as the miracle pills and prescriptions scams, resulted in $7 million in losses in 2021, but nearly $30 million in 2020.  While these types of scams seem generic and easily spotted, they still work, and so it’s important to be aware and avoid them.

Problems with your account

Many emails hitting the spam box attempt to trick users of various services into believing that there is a problem with their account. The problems cover all sorts of services, including streaming platforms, email providers, antivirus subscriptions, and even public records.

Image 14 – Emails indicating problems with an account

If the links are clicked, the recipient is presented with landing pages that mimic the respective services. Any details that are entered will likely be phished, leading to account takeover and/or access to personal records. However, some domains encountered in these cases may do more than just steal information, they could deliver malware too.

Image 15 – Likely malicious activity

Billing scams

Another frequently encountered scam surrounds billing. Many of these appear to be unexpected bills for services the recipient never purchased.

Image 16 – Billing scam examples

These emails include attachments that are designed to look like official invoices. Interestingly, most of the attachments that we looked at this time were harmless. The goal is to get the recipient to call what appears to be a toll-free number.

Image 17 – Billing scam attachments

While we haven’t called any of these numbers, the experience usually unfolds like a standard customer service call. In the end the “agents” simply claim the charges—which never existed in the first place—have been removed. Meanwhile the scammers steal any personal or financial information provided during the call.

Malicious billing scams

While most billing scams we encountered played out as described above, a few did indeed contain malware.

In this example, the email appears to come from an internet service provider, informing us that our monthly bill is ready.

Image 18 – A malicious billing scam email

An invoice appears to be attached, stored within a .zip file. If the recipient opens it and double clicks the file within, a command prompt appears.

Image 19 – Command prompt launched by attachment

This may seem unusual to the recipient, especially since no invoice appears, but by this point it’s too late. The file contains a script that launches PowerShell and attempts to download a remote file.

Image 20 – Contents of batch file

While the remote file was no longer available at the time of analysis, there is a high likelihood it was malicious. But even though we were unable to determine its contents, Secure Malware Analytics flagged the script execution as malicious.

Defending yourself

Knowing about prevalent scams, especially during the holiday season, is a first step in guarding against them. Granted the bad actors who distribute these spam campaigns do everything they can to make their scams look legitimate.

Fortunately, there are several things that you can do to identify scams and defend against them:

  • Be wary of any unsolicited offers, giveaways, and other suspicious communications.
  • Ensure that the sender’s email address corresponds with the organization it claims to come from. In many of the examples above they do not.
  • When holiday shopping, stick to known vendors, visiting their websites directly or using their official apps.
  • Do not open links or attachments in emails coming from unknown sources.

But even the best of us can be fooled, and when overseeing a large operation it’s more a matter of when, rather than if, someone clicks on the wrong link. There are elements of the Cisco Secure portfolio that can help for when the inevitable happens.

Societies are reliant on the services provided by critical infrastructure sectors like telecommunication, energy, healthcare, transportation, and information technology. Safety and security are necessary for the optimal operation of these critical infrastructures. Critical infrastructure is made up of digital

McAfee 2023 Threat Predictions: Evolution and Exploitation

By McAfee Labs

As 2022 draws to a close, the Threat Research Team at McAfee Labs takes a look forward—offering their predictions for 2023 and how its threat landscape may take shape.  

This year saw the continued evolution of scams, which is unlikely to slow down, as well as greater adoption of Chrome as an operating system. It also saw the introduction of AI tools that are easy and accessible to virtually anyone with a phone or laptop, which will continue to have significant implications, as will the fluctuating popularity of cryptocurrency and the emergence of “Web3.”  

Advances such as these have set the stage for 2023, which will continue to reshape our interactions with technology—advances that bad actors will try to exploit, and in turn, us.  

Yet as the threat landscape continues to evolve, so do the ways we can protect ourselves. With that, we share McAfee’s threat predictions for 2023, along with insights and advice that can help us enjoy the advances to come with confidence. 

AI Goes Mainstream and the Distribution of Disinformation Rises 

By Steve Grobman, Chief Technology Officer 

Humans have been fascinated by artificial intelligence (AI) for almost as long as we’ve been using computers. And in some cases, even fearful of it. Depictions in pop culture range from HAL, the sentient computer from 2001: A Space Odyssey to Skynet, the self-aware neural network at the center of the Terminator franchise. The reality of current AI technologies is both more complicated and less autonomous than either of these. While AI is rapidly evolving, humans remain at the heart of it, and whether it’s put to beneficial or nefarious use. 

Within the last few months, creating AI-generated images, videos, and even voices are no longer strictly left to professionals. Now anyone with a phone or computer can take advantage of the technology using publicly available applications like Open AI’s Dall-E or stability.ai’s Stable Diffusion. Google has even made creating AI-generated videos easier than ever. 

What does this mean for the future?  It means the next generation of content creation is becoming available to the masses and will only continue to evolve. People both at work and at home will have the ability to create the AI-generated content in minutes. Just as desktop publishing, photo editing, and inexpensive photorealistic home printers created major advances that empowered individuals to create content that previously required a professional designer, these technologies will enable sophisticated outputs with minimal expertise or effort.   

Advances in desktop publishing and consumer printing also provided benefits to criminals, enabling better counterfeiting and more realistic manipulation of images. Similarly, these emerging next-generation content tools will also be used by a range of bad actors. From cybercriminals to those seeking to falsely influence public opinion, these tools will empower scammers and propagandists to take their tradecraft to the next level with more realistic results and significantly improved efficiency.  

This is especially likely to ramp up in 2023 as the U.S. begins the 2024 presidential election cycle in earnest. Globally, the political environment is polarized. The confluence of the emergence of accessible next-generation generative AI tools and what is sure to be a highly contested 2024 election season is a perfect storm for creating and distributing disinformation for political and monetary gain.  

We’ll all need to be more mindful of the content we consume and the sources that it originates from. Fact-checking images, videos, and news content, something that’s already on the rise, will continue to be a necessary and valuable part of media consumption. 

New Year, New Scams 

By Oliver Devane, Security Researcher 

Cryptocurrency scams 

In 2022 we saw several online scams making use of existing content to make crypto scams more believable. One such example was the double your money cryptocurrency scam that used an old Elon Musk video as a lure. We expect such scams to evolve in 2023 and make use of deep fake videos, as well as audio, to trick victims into parting ways with their hard-earned money.  

Investment scams 

The financial outlook of 2023 remains uncertain for many people. During these times, people often look for ways to make some extra money and this can lead them vulnerable to social media messages and online ads that offer huge financial gains for little investment.   

According to the IC3 2021 report, the losses for financial scams increased from $336,469,000 in 2020 to $1,455,943,193 in 2021, this shows that this type of scam is growing by an enormous amount, and we expect this to continue. 

Fake loans 

Unfortunately, scammers will often target the most vulnerable people. Fake loan scams are one such scam where the scammers know that the victims are desperate for the loan and therefore are less likely to react to warning signs such as asking for an upfront fee. McAfee predicts that there will be a large increase in these types of scams in 2023. When looking for a loan, always use a trusted provider and be careful of clicking on online ads.  

Metaverse 

Metaverses such as Facebook’s Horizon enable their users to explore an online world that was previously unimaginable. When these platforms are in the early stages, malicious actors will usually attempt to exploit the lack of understanding of how they work and use this to scam people. We have observed phishing campaigns targeting users of these platforms in 2022 and we expect this to increase dramatically in 2023 as more and more users sign up for the platforms.   

The Rise of ChromeOS Threats 

By Craig Schmugar, McAfee Senior Principal Engineer 

More than 25 years ago, Windows 95 became the platform of choice not just for millions of users around the globe, but for malware authors targeting those users. Over the years, Windows has evolved, as has the threat landscape. Today, Windows 10 and 11 make up the majority of the desktop PC market, but thanks to the rise of the mobile Internet, device diversity has greatly evolved since the advent of Windows 95.   

Over five years ago, Android overtook Windows as the world’s most popular OS and with this shift bad actors have been pursing alternative methods of attack. The ultimate vectors are those which impact users across a spectrum of devices. Email and web-based scams (some of which are outlined in the blog above) are as prolific as ever as these technologies are ubiquitous across desktop and mobile devices.  

Meanwhile, other technologies span across desktop and mobile experiences as well. For Google, such cross-platform capabilities are highlighted by increased adoption of ChromeOS and a few underlying technologies. This includes 270 million active Android users and a 270% increase in Progressive Web Application (PWA) installations [https://chromeos.dev].  ChromeOS’ ability to run Android applications, combined with its wide-spread adoption, provides the climate for increased attention by those with ill intentions.   

Similarly, adoption of PWAs provide bad actors with additional incentive to deliver deceptive and imposter attacks through this multi-OS channel, including ChromeOS, iOS, MacOS, and Windows.   

Finally, on the heels of COVID restrictions that impacted schools in various countries, Google reported 50 million students and educators worldwide [https://chromeos.dev] using ChromeOS. Many users will be unaware of malicious Chrome extensions lurking in the Chrome Web Store. 

All of this means that the stage is set for a marked increase in threats impacting Chromebook in the year to come. In 2023, we can expect to see Chromebook users among millions of unsuspecting victims that download and run malicious content, whether from malicious Android Apps, Progressive Web Apps, or Chrome Web Store extensions, users should be leery of popups and push notifications urging them to install untrusted apps. 

Web3 Threats will take advantage of FOMO 

By Fernando Ruiz, Senior Security Researcher 

Editor’s Note: Web3? FOMO? If you’re already lost, you’re not alone. Web3 is a term some use to encompass decentralized internet services, technologies like Bitcoin and Non-Fungible Tokens (digital art that collectors can purchase with cryptocurrency). Still confused? A lot of people are. This New York Times article is a good primer on what is currently considered Web3.   

As for FOMO, that’s just an acronym meaning the “Fear of Missing Out.” That nagging feeling, most often felt by extroverts, that others are out there having more fun than them and that they’re missing the party. 

Whether you invest in cryptocurrency or just see the headlines on Twitter, no doubt you’ve seen that the price of cryptocurrency has sharply declined during 2022. These fluctuations are becoming more normal as crypto becomes even more mainstream. It’s very likely that the value of crypto will rise again.  

When the last upturn in valuation happened near the start of the pandemic, the hype about crypto also skyrocketed. Suddenly Bitcoin and other cryptocurrencies were everywhere. Out of that, rose the concept of Web3, with more companies investing in new applications over blockchain (the technology that is the backbone of cryptocurrency).  

McAfee predicts that the popularity of cryptocurrency will rise again, and consumers will hear much more about Web3 concepts like decentralized finance (DeFi), decentralized autonomous organizations (DAOs), self-sovereign identity (SSI) and more.  

Some amateur investors, remembering the rapid rise of the value of Bitcoin earlier this decade, won’t want to miss out on what they think will be a great opportunity to get rich quick. It’s this group that bad actors will seek to exploit, offering up links or applications that play on these users’ crypto/Web3 FOMO.  

As crypto bounces back and initial awareness of decentralization grows in the general population, consumers will begin to explore these Web3 offerings without fully understanding what they mean or what dangers they should be aware of, leaving them open to scams as they invest time and money into crypto or creating their own NFT content. These scams could entice users to click on a link or download an app that appears to legitimately interact with some blockchains, but in actuality:  

  • Does not have the functionality to interact with any blockchain. 
  • Are designed to collect traditional currency for fees or services that do not actually provide any value. 
  • Possess aggressive adware that compromises user’s privacy, time, device performance, data usage, and drains their device battery. 

Additionally, when consumers DO hold crypto, NFT, digital land, or other blockchain financial assets they are going to be targeted for more sophisticated threats that can drain their funds: smart contracts, exchanges, digital wallets, and synchronization services can all be associated with hidden authorizations that allow a third party (potentially a bad actor) to take control of the assets. It’s important that users read the terms and conditions of any app they download, especially those that will be accessing ANY type of financial institution or currency, whether traditional or crypto.  

Social engineering will also continue to be a top entry point for cybercriminals. The complexity of the attacks will evolve as the technology does, which will require more preparation and understanding of how Web3 applications and tools work in order to safely interact with them. 

What has emerged from the world of Web3 thus far, while exciting, has also expanded attack surfaces and vectors, which we expect to see grow throughout 2023 as Web3 evolves.

What Are Tailgating Attacks and How to Protect Yourself From Them

By McAfee

Whether you’re spending time on the web or working in the office, you want peace of mind knowing that you are in a safe environment. While most of us know to take precautions when online — protecting ourselves from things like phishing attacks and other cyber threats — we should also attend to our physical security. 

One concern is tailgating — a social engineering attack where someone gets physical access to a business to take confidential information or do other harm. 

Here are some ways to protect yourself from tailgating attacks, such as an unauthorized person following you into a restricted area while on the job. 

What is a tailgating attack?

Tailgating is a type of social engineering attack where an unauthorized person gains physical access to an off-limits location — perhaps a password-protected area — where they might steal sensitive information, damage property, compromise user credentials or even install malware on computers. 

Piggybacking” is closely related to tailgating, but it involves consent from the duped employee. So, while a worker might be unaware that someone has tailgated them into a restricted area with piggybacking, the hacker might convince a worker to provide access because they are posing as, say, a delivery driver. 

Who’s at risk of tailgating attacks?

Companies, particularly at risk of being targeted by tailgating scams, include those: 

  • With many employees, often moving inside and out of the premises 
  • With multiple entrance points into a building 
  • That receive deliveries of food, packages, documents, and other things regularly 
  • That have many subcontractors working for them 
  • Where employees aren’t thoroughly trained in physical and cybersecurity protocols 

Generally speaking, companies with robust security systems in place — including using biometrics, badges, or other identity and information security measures — are better protected from tailgating and piggybacking attacks.  

But that’s not to say that some smooth-talking fraudster can’t talk someone into letting them in or finding some way around those protections. 

What are common tailgating methods?

Common types of tailgating attacks that you should be aware of on the job include:  

  • Someone walking behind you into a secure area, depending on your common courtesy to keep the door open for them 
  • A courier or delivery driver who aren’t what they seem 
  • Someone with their hands full of items to trick you into opening the door for them 
  • A person who claims they’ve lost their work ID or forgotten it at home, so that you grant them admittance 

How to protect yourself from tailgating attacks 

Protecting yourself from tailgating attacks is partly a matter of learning about the issue, raising your level of awareness on the job, and depending on your employer, putting in place more effective security systems.  

Some solutions include: 

Increased security training

Many companies know how to train employees to recognize, avoid, and cope with online security issues but may forget to provide the same diligence to physical security. How to spot and deal with threats should be part of this training, plus cultivating an awareness of surroundings and people who might be out of place.   

Management should offer a clearly stated security policy taught to everyone, which might insist that no one be allowed into a secure area without the proper pass or identification. As the security policy is updated, all employees should be aware of changes and additions. 

These security measures should be part of an overall protection program, like McAfee+, which includes antivirus software, a firewall, identity monitoring, password management, web protection, and more. 

Smart badges and cards

If you have a large business spread over several floors, it can be hard for employees to know who works there and who doesn’t, leaving them susceptible to tailgating and piggybacking attacks. Requiring smart badges and cards to access restricted areas can help cut back on unauthorized intrusions and provide better access control. 

Building fully staffed reception areas with dedicated security personnel could also be part of a larger security system. 

Biometric scanners

Biometric scanners are an even more advanced way to provide proper authentication for a worker’s identity. They scan a unique physical or audible feature of a person and compare it to a database for approved personnel.  

Examples of biometric security include: 

  • Voice recognition 
  • Iris recognition 
  • Fingerprint scans 
  • Facial recognition 
  • Heart-rate sensors 

Understanding social engineering

One reason people are vulnerable to physical and cyberattacks is that they lack education on social engineering and the kinds of threats it poses.  

Workers need to understand the full range of social engineering techniques and know-how to protect themselves, whether in their social media accounts or physical work environment.  

For their part, companies can use simulated phishing emails and tailgating attacks to raise awareness and underline how to follow protocols in dealing with them. 

Video surveillance

If there are many ways to enter a business, it may make sense to put video surveillance on all entrances. Advanced video surveillance systems can use artificial intelligence (AI) and video analytics to scan the faces of people entering and compare them to a database of employee features.

Threat hunting with MITRE ATT&CK and Wazuh

By The Hacker News
Threat hunting is the process of looking for malicious activity and its artifacts in a computer system or network. Threat hunting is carried out intermittently in an environment regardless of whether or not threats have been discovered by automated security solutions. Some threat actors may stay dormant in an organization's infrastructure, extending their access while waiting for the right

Undersea Cables and Cyber Physical Risks.

By Martin Lee

Cyber security implies protecting the confidentiality, availability and integrity of computer systems and networks. Often security researchers and security teams focus on threats to software and the risks associated with authenticating and managing users. However, computing systems are built upon a tall stack of computing resources.  

Each layer within the stack is exposed to specific threats which need to be considered as part of a cyber security strategy. As the threat landscape evolves and exposure to risk changes, organizations need to review their threat exposure and consider if current mitigations are sufficient for their needs. 

The recent disruption of the Nord Stream submarine gas pipeline in the Baltic Sea by an apparent act of sabotage highlights the risks to infrastructure located beneath the waves. The telecommunications infrastructure that carries internet traffic between countries and continents is often provided by submarine cables. These cables are relatively few in number but carry vast amounts of internet and enterprise traffic, potentially from many different service providers. 

The seabed is a challenging environment for infrastructure. Sea water is corrosive, the pressure on the ocean floor can be extreme, while earthquakes, ship’s anchors and dredging provide additional risks to may result in the severing of a cable. Submarine cables are only expected to achieve a lifespan in the region of 25 years before failure.  

Repairing or replacing a submarine cable is expensive and time consuming. It may be many months before a failed cable can be repaired or replaced. In the absence of a functioning cable, internet connections must be rerouted to avoid disruption. However, this risks saturating the remaining infrastructure and adversely affecting the quality of connections.  

Organizations that require high availability international or intercontinental network connections should review their exposure to the risk of submarine cables failure. The nature of this risk will depend on how services are currently delivered.  

  1. Services may be delivered by a single service provider with a guaranteed level of service. In this case, organizations should review their provider’s contingencies in case of loss of one or more submarine cables and verify that these meet requirements.
  2. Piecemeal connections delivered by multiple providers may have been assembled to satisfy needs. Organizations should verify that this connectivity is able to support network requirements if one or more of the connections are unavailable. Organizations should seek to avoid single points of failure such as landing stations or conduits that may be shared by what otherwise appear to be independent connections.
  3. Software-defined Wide Area Networking (SD-WAN) is often used to route traffic in the most efficient manner to meet requirements. The flexibility of the approach implies that the loss of any single physical path would not lead to the loss of connectivity, but the increased flow of data within remaining paths may lead to a degradation in connection quality. Organizations should model how the loss of an undersea cable would affect their services and check if additional redundancy is necessary. 

At the time of writing there is no specific threat to undersea infrastructure. Other than attacks against terrestrial cables, no cable damage has been shown to be due to sabotage. Nevertheless, the Secretary General of NATO has stressed the importance of undersea cables to civilian society and military capability [1]. The British Chief of Defense Staff has warned how seriously intentional damage to telecommunications cables would be taken [2]. 

Physical infrastructure can not be taken for granted. Organizations would do well to review the impact of one or more submarine cables being taken out of service. Preparing response plans and contingencies in advance ensures that disruption is kept to a minimum in the event that such a scenario occurs.

ThreatWise TV: Exploring Recent Incident Response Trends

By Ben Nahorney

Today we’re examining some of the revelations in the Q3 Cisco Talos Incident Response Trends Report. This document is an anonymized look at of all the engagements that the Cisco Talos Incident Response team have been involved in over the previous three months. It also features threat intelligence from our team of researchers and analysts.  

To start, take a watch of this episode of ThreatWise TV which explores how these trends have evolved since the previous quarter. Our guests also talk about incidents and cyber-attacks that they themselves have consulted on recently, including a particularly interesting insider threat case. 

Highlights of the Q3 Cisco Talos Incident Response report 

Ransomware returned as the top threat this quarter, after commodity trojans narrowly surpassed ransomware last quarter. Ransomware made up nearly 18 percent of all threats observed, up from 15 percent last quarter. Cisco Talos Incident Response (CTIR) observed high-profile families, such as Vice Society and Hive, as well as the newer family Blast Basta, which first emerged in April of this year.   

Also noteworthy is the fact that CTIR saw an equal number in ransomware and pre- ransomware engagements this quarter, totalling nearly 40 percent of threats observed. Pre-ransomware is when we have observed a ransomware attack is about to happen, but the encryption of files has not yet taken place. 

Pre-ransomware comprised 18 percent of threats this quarter, up from less than 5 percent previously. While it’s difficult to determine an adversary’s motivations if encryption does not take place, several behavioral characteristics bolster Talos’ confidence that ransomware may likely be the final objective. In these engagements adversaries were observed deploying frameworks such as Cobalt Strike and Mimikatz, alongside numerous enumeration and discovery techniques.  

Commodity malware, such as the Qakbot banking trojan, was observed in multiple engagements this quarter. In one engagement, several compromised endpoints were seen communicating with IP addresses associated with Qakbot C2 traffic. This activity coincides with a general resurgence of Qakbot and its delivery of emerging ransomware families and offensive security frameworks that we have not previously observed Qakbot deploy. This comes at a time where competing email-based botnets like Emotet and Trickbot have suffered continued setbacks from law enforcement and tech companies.  

Other threats this quarter include infostealers like Redline Stealer and Raccoon Stealer. Redline Stealer was observed across three engagements this quarter, two of which involved ransomware. The malware operators behind Raccoon introduced new functionality to the malware at the end of June, which likely contributed to its increased presence in engagements this quarter.  

As infostealers have continued to rank highly in CTIR engagements, let’s explore them in a bit more detail. 

Why infostealers proliferate  

Throughout the incidents discussed over the last few quarters, and CTIR engagements in general, information stealing plays a big part of the attackers’ TTPs.   

From a high level, infostealers can be used to gain access a variety of sensitive information, such as contact information, financial details, and even intellectual property. The adversaries involved often proceed to exfiltrate this information and may then attempt to sell it in dark web forums, threaten to release it if a ransom isn’t paid, among other things.  

While these instances can and do crop up in CTIR engagements, many of the infostealers seen in this space are used for accessing and collecting user credentials. Once an attacker has gained an initial foothold on a system, there are many places within an operating system that they can look for and collect credentials through the practice of credential dumping.   

These stolen credentials may be offered up for sale on the dark web, alongside the stolen information mentioned above, but they can also prove to be a key weapon in an attacker’s arsenal. Their usefulness lies in one simple concept—why force your way into a system when you can just log in?  

There are several advantages for bad actors that use this approach. Probably the most oblivious of these is that using pre-existing credentials is far more likely to go unnoticed than other more flagrant tactics an attacker can use. If part of the goal of an attack is to remain under the radar, activities carried out by “known users” are less likely to trigger security alerts when compared to tactics such as exploiting vulnerabilities or downloading malware binaries.  

Adversaries tend to seek credentials with higher privileges, allowing them further control over the systems they compromise, with those including administrative access being the crown jewels.  

User credentials can not only provide an attacker with means to elevate privileges and establish persistence on a system, but also to move laterally through a network. Some credentials, especially those with administrative privileges, can offer access to multiple systems throughout a network. By obtaining them, many more options become available to further an attack.  

Repeat offenders  

There are several threats involved in information stealing that appear repeatedly in CTIR engagements over the last few quarters.  

Perhaps the most notorious is Mimikatz—a tool used to pull credentials from operating systems. Mimikatz is not malware per-se and can be useful for penetration testing and red team activities. But bad actors leverage it as well, and over the last few quarters CTIR has observed it being used in ransomware-as-a-service attacks, as well as pre-ransomware incidents.   

CTIR has also observed Redline Stealer being utilized by adversaries in CTIR engagements across quarters. This infostealer has grown in popularity as a supplementary tool used alongside other malware. On more than one occasion, CTIR has identified stolen credentials on the dark web that claimed to have been obtained via Redline Stealer.  

Other information stealers seen across the last few quarters include the Vidar information stealer, Raccoon Stealer, and SolarMaker, all of which have been used to further an adversary’s attacks.   

Insider threats 

Over the last several months, Talos has seen an increasing number of engagements involving insider threats. In one engagement this quarter, passwords were reset through a management console of a perimeter firewall that a disgruntled employee had access to.   

The organization’s team changed all associated passwords but overlooked one administrative account. On the following day, someone logged in using that account, deleted all other accounts and firewall rules, and created one local account, likely to provide persistence.  

You’ll hear Alexis Merritt, Incident Response Consultant for Cisco Talos, talk about this more in the ThreatWise TV episode. 

To help protect against this threat when an individual leaves an organization, steps like disabling accounts and ensuring that connections to the enterprise remotely through VPN has been removed can be very valuable. Implementing a mechanism to wipe systems, especially for remote employees, is important as well.  

For more on this topic, Cisco Secure recently put together a white paper on the Insider Threat Maturity FrameWork.

How to protect  

In several incidents over the last few quarters that involved information stealers, multi-factor authentication (MFA) was not properly implemented by the organizations impacted, providing adversaries an opportunity to infiltrate the networks. MFA tools like Cisco Secure Access by Duo can prevent attackers from successfully gaining access. 

Connecting with Wolfgang Goerlich 

And finally, Cisco Advisory CISO Wolfgang Goerlich has created this storytelling video, to help people think about incident response in a new way:

Hot on the Trail of a Mass-School-Shooting Hoaxer

For months, an anonymous caller has terrorized communities around the US by reporting false shooting threats. We know how they did it. The question is, why?

How can I help protect my company from phishing attacks?

By Greg Barnes

I’m sure you’ve seen them — emails or messages that sound alarming and ask you to act quickly. We live in a digital world that produces hundreds of messages and alerts every day. It’s often hard to determine the validity of a suspicious message or phishing email. Whether you are an administrator, or an end-user, it can be overwhelming to accurately identify a malicious message. When in doubt, here are some questions you should ask yourself:

Is the message from a legitimate sender?

Do I normally receive messages from this person?

If there’s a link, can I tell where it’s sending me?

Attackers continue to evolve their methods, and they’re highly educated on the defenses they come up against in the wild. They’ll craft messages that do not involve any traditional indicators of compromise, such as domains, IP address, or URL links. They’ll also start their attacks by sending messages as an initial lure to establish trust, before sending an email with altered invoice or one claiming to be a helpless employee attempting to get their payroll fixed.

Phishing is a socially-based attack type, one where the threat actors focus on human behavior. When these attacks target organizations, there are multiple levels of attack at play. One that focuses on behavioral patterns and workflow, and the other centers on the victim’s emotional boundaries, such as targeting their desire to help others. You see this pattern frequently in Business Email Compromise (BEC) attacks.

Below, we’ve placed an example of a lure, which will test the victim to see if there is a means to quickly establish trust. Here, the threat actor is pretending to be the Chief Financial Officer (CFO) of the victim’s organization. If the lure is successful, then the threat actor will progress the attack, and often request sensitive records or wire transfers. Notice that in the email headers, the person pretending to be the CFO is using a Gmail account, one that was likely created just for this attack. The message is brief, stresses importance and urgency, and requests assistance, playing on the victim’s workflow and desire to help an executive or someone with authority.

The example below is a simplified one, to be sure, but the elements are legitimate. Daily, emails like this hit the inboxes of organizations globally, and the attackers only need to locate a single victim to make their efforts payout.

Figure 1: An example of an Initial lure to establish trust

In the FBI / IC3 2021 Internet Crime Report, there were nearly 20,000 Business Email Compromise complaints filed, with an adjusted loss of nearly 2.4 billion dollars.  While spoofing the identity of an executive is certainly one way to conduct a BEC attack, the FBI says that threat actors have started leveraging the normality of hybrid-work to target meeting platforms to establish trust and conduct their crimes. When successful, the funds from the fraudulent wire transfers are moved to crypto wallets and the funds dispersed, making recovery harder.

So as an end user what can you do to protect your organization? Be mindful anytime you receive an urgent call to action, especially when the subject involves money. If your workflow means that you regularly receive these types of requests from the specific individual, verify their identity and the validity of the request using another channel of communication, such as in person or via phone. If you do validate their identity via the phone, take care to avoid calling any numbers listed in the email.

Cisco Secure Email helps stop these types of attacks by tracking user relationships and threat techniques. These techniques often include account takeover, spoofing and many more. Using an intent-based approach allows Secure Email to detect and classify business email compromises and other attacks, so administrators are empowered to take a risk-based approach to stopping these threats.

Cybercrime’s Most Wanted: Four Mobile Threats that Might Surprise You

By McAfee

It’s hard to imagine a world without cellphones. Whether it be a smartphone or a flip phone, these devices have truly shaped the late 20th century and will continue to do so for the foreseeable future. But while users have become accustomed to having almost everything they could ever want at fingertips length, cybercriminals were busy setting up shop. To trick unsuspecting users, cybercriminals have set up crafty mobile threats – some that users may not even be fully aware of. These sneaky cyberthreats include SMSishing, fake networks, malicious apps, and grayware, which have all grown in sophistication over time. This means users need to be equipped with the know-how to navigate the choppy waters that come with these smartphone-related cyberthreats. Let’s get started.

Watch out for SMSishing Hooks

If you use email, then you are probably familiar with what phishing is. And while phishing is commonly executed through email and malicious links, there is a form of phishing that specifically targets mobile devices called SMSishing. This growing threat allows cybercriminals to utilize messaging apps to send unsuspecting users a SMSishing message. These messages serve one purpose – to obtain personal information, such as logins and financial information. With that information, cybercriminals could impersonate the user to access banking records or steal their identity.

While this threat was once a rarity, it’s rise in popularity is two-fold. The first aspect being that users have been educated to distrust email messages and the second being the rise in mobile phone usage throughout the world. Although this threat shows no sign of slowing down, there are ways to avoid a cybercriminal’s SMSishing hooks. Get started with these tips:

  1. Always double-check the message’s source. If you receive a text from your bank or credit card company, call the organization directly to ensure the message is legit.
  2. Delete potential SMSishing Do not reply to or click on any links within a suspected malicious text, as that could lead to more SMSishing attempts bombarding your phone.
  3. Invest in comprehensive mobile security. Adding an extra level of security can not only help protect your device but can also notify you when a threat arises.

Public Wi-Fi Woes  

Public and free Wi-Fi is practically everywhere nowadays, with some destinations even having city-wide Wi-Fi set up. But that Wi-Fi users are connecting their mobile device to may not be the most secure, given cybercriminals can exploit weaknesses in these networks to intercept messages, login credentials, or other personal information. Beyond exploiting weaknesses, some cybercriminals take it a step further and create fake networks with generic names that trick unsuspecting users into connecting their devices. These networks are called “evil-twin” networks. For help in spotting these imposters, there are few tricks the savvy user can deploy to prevent an evil twin network from wreaking havoc on their mobile device:

  1. Look for password-protected networks. As strange as it sounds, if you purposely enter the incorrect password but are still allowed access, the network is most likely a fraud.
  2. Pay attention to page load times. If the network you are using is very slow, it is more likely a cybercriminal is using an unreliable mobile hotspot to connect your mobile device to the web.
  3. Use a virtual private network or VPN. While you’re on-the-go and using public Wi-Fi, add an extra layer of security in the event you accidentally connect to a malicious network. VPNs can encrypt your online activity and keep it away from prying eyes. 

Malicious Apps: Fake It till They Make It

Fake apps have become a rampant problem for Android and iPhone users alike. This is mainly in part due to malicious apps hiding in plain sight on legitimate sources, such as the Google Play Store and Apple’s App Store. After users download a faulty app, cybercriminals deploy malware that operates in the background of mobile devices which makes it difficult for users to realize anything is wrong. And while users think they’ve just downloaded another run-of-the-mill app, the malware is hard at work obtaining personal data.

In order to keep sensitive information out of the hands of cybercriminals, here are a few things users can look for when they need to determine whether an app is fact or fiction:

  1. Check for typos and poor grammar. Always check the app developer name, product title, and description for typos and grammatical errors. Often, malicious developers will spoof real developer IDs, even just by a single letter or number, to seem legitimate.
  2. Examine the download statistics. If you’re attempting to download a popular app, but it has a surprisingly low number of downloads, that is a good indicator that an app is most likely fake.
  3. Read the reviews. With malicious apps, user reviews are your friend. By reading a few, you can receive vital information that can help you determine whether the app is fake or not.

The Sly Operation of Grayware

With so many types of malware out in the world, it’s hard to keep track of them all. But there is one in particular that mobile device users need to be keenly aware of called grayware. As a coverall term for software or code that sits between normal and malicious, grayware comes in many forms, such as adware, spyware or madware. While adware and spyware can sometimes operate simultaneously on infected computers, madware — or adware on mobile devices — infiltrates smartphones by hiding within rogue apps. Once a mobile device is infected with madware from a malicious app, ads can infiltrate almost every aspect on a user’s phone. Madware isn’t just annoying; it also is a security and privacy risk, as some threats will try to obtain users’ data. To avoid the annoyance, as well as the cybersecurity risks of grayware, users can prepare their devices with these cautionary steps:

  1. Be sure to update your device. Grayware looks for vulnerabilities that can be exploited, so be sure to always keep your device’s software up-to-date.
  2. Beware of rogue apps. As mentioned in the previous section, fake apps are now a part of owning a smartphone. Use the tips in the above section to ensure you keep malicious apps off of your device that may contain grayware.
  3. Consider a comprehensive mobile security system. By adding an extra level of security, you can help protect your devices from threats, both old and new.

Cyber Insurance and the Attribution Conundrum

By Martin Lee

Written by Martin Lee and Richard Archdeacon.


Lloyds of London have recently published a Market Bulletin1 addressing the wording of cyber insurance policies to exclude losses arising from:

state backed cyber-attacks that (a) significantly impair the ability of a state to function or (b) that significantly impair the security capabilities of a state.

The concern raised is that this sort of attack will produce losses that the market cannot absorb. Most insurance policies already include provisions that exclude the consequences of armed conflict. Applying these to potential cyber warfare is a logical step.

The bulletin includes the tenet to:

set out a robust basis by which the parties agree on how any state backed cyber- attack will be attributed to one or more states.”

What should the CISO be thinking of when reviewing such an exclusion clause, how can we clearly define this key term and what issues may arise?

What Is Attribution?

Attribution is the science of identifying the perpetrator of a crime. In cyber attacks, this is arrived at by comparing the evidence gathered from an attack with evidence gathered from previous attacks that have been attributed to known perpetrators to identify similarities.

In practice, statements of attributions are carefully phrased. Rarely is evidence clear-cut. Frequently attribution is labelled as being ‘consistent with’ a threat actor, or wrapped in words of estimative probability such as ‘highly likely’, ‘probably’, ‘possibly’ etc.

Threat Actors

The malicious actors who conduct cyber attacks are referred to as threat actors. The cyber research community identifies and keeps track of the actions of these threat actors, publishing compendia of known actors such as those made available by MITRE2 or Malpedia3.

Rarely do threat actors identify their true identities, they may actively try to confuse or frustrate attribution. Many of the named groups may be synonyms of other groups, equally many of the chains of evidence used to attribute groups may be incorrect. The compendia of threat actors should not be considered as reaching the evidence threshold of “beyond reasonable doubt”.

Some identified threat actor groups are assumed to be criminal gangs due to the nature of their activity. Others appear to be conducting attacks solely to further the geopolitical aims of a nation state and are assumed as being state sponsored or state backed. Some of these groups have been able to be associated with specific national intelligence agencies or state apparatus.

Agreeing a Robust Basis

The following are four practical factors to consider when setting out a robust basis for attribution of attacks in a contractual basis.

Step 1 – Collect forensic evidence.

No attribution of an attack can be made without forensic evidence. CISOs should ensure that they are able to gather forensic evidence from attacks to identify as much information as possible regarding how an attack was carried out, and the infrastructure used by the attacker. This requires a basic level of security telemetry gathering with the ability to secure and query this data.

This forensic capability, how evidence will be gathered and preserved, should be agreed with the insurer. However, both parties must bear in mind that attackers may destroy or tamper with evidence, and in the urgency of halting an attack, forensic evidence may be compromised or omitted.

The CISO should be prepared to discuss internally with senior executives the possibly competing priorities of stopping an attack versus collecting good forensic evidence.

Step 2 – Define how attribution will be made.

The attribution of a specific attack must be made by comparing evidence gathered from the attack with that of previous attacks. CISOs should agree the process by which forensic artifacts are used to attribute attacks and the degree of certitude necessary to declare an attack as having been carried out by a specific group.

The set of organisations trusted to assert attribution should be agreed. Attribution made by national bodies such as NCSC, CISA or ENISA may be assumed to be reliable, as may those made by major security vendors (such as Cisco) with expertise and resources that a CISO will never have inhouse. However, anyone can suggest attribution. CISOs should be certain to insist on the exclusion of assertions that have not been confirmed by a trusted entity.

This raises the question as to whether a trusted organisation would be prepared to support their attribution in a scenario where they would have to expose their intelligence sources and methodologies to examination. Attribution may be based on classified intelligence, or made according to ‘fair efforts’ that fall below the legal threshold of “on the balance of probabilities.”

Step 3 – Consider the volatility of attribution.

The gathering of evidence and intelligence is a continuing process. Information previously assumed to be fact may be subsequently identified as incorrect or a purposeful red herring. New evidence may be identified months or years after an attack that changes the estimated attribution of prior attacks.

CISOs must determine a period after which the attribution of attack (if made) will not be changed even if subsequent evidence is uncovered.

Step 4 – Define the nature of state backing.

CISOs should agree what constitutes state backing. Ideally CISOs should agree with their insurers the set of threat actor groups (and their synonyms) which are considered to be ‘state backed’.

State involvement in cyber attacks is a spectrum of activity. Criminal threat actors may be under various degrees of state tolerance or encouragement without being fully backed by a nation state. Some criminal groups may be under partial state direction, acting in a manner akin to privateers. Some state backed actors may indulge in criminal style attacks to boost their coffers.

In any case, criminal and state sponsored actors can easily be confused. They may choose to use the same tools or apply the same techniques to conduct their activities. Non-state threat actors may come into possession of state developed tools which may have been stolen or traded without permission.

Some threat actors may actively resort to influence attribution, either through choice of tooling, or through sock puppet accounts attesting attribution, to increase pressure on CISOs to pay ransoms by influencing if insurance is paid out or not.

The decision line where an attack can be referred to a ‘state backed’ is a fine one that requires consideration and agreement.

Conclusion

Changes bring opportunities, the need for this robust process may cause complications for CISOs. But it is an opportunity for CISOs to review the details of cyber insurance contracts and to hammer out the details of how issues of attribution will be determined.

Iranian APT42 Launched Over 30 Espionage Attacks Against Activists and Dissidents

By Ravie Lakshmanan
A state-sponsored advanced persistent threat (APT) actor newly christened APT42 (formerly UNC788) has been attributed to over 30 confirmed espionage attacks against individuals and organizations of strategic interest to the Iranian government at least since 2015. Cybersecurity firm Mandiant said the group operates as the intelligence gathering arm of Iran's Islamic Revolutionary Guard Corps (

Mobile devices are not only becoming more powerful but also more vulnerable to cyberattacks, making mobile security an increasingly important concern for enterprises. This

Cisco Talos — Our not-so-secret threat intel advantage

By Neville Letzerich

Security tools are only as good as the intelligence and expertise that feeds them. We’re very fortunate to have our security technologies powered by Cisco Talos, one of the largest and most trusted threat intelligence groups in the world. Talos is comprised of highly skilled researchers, analysts, and engineers who provide industry-leading visibility, actionable intelligence, and vulnerability research to protect both our customers and the internet at large.

The Talos team serves as a crucial pillar of our innovation — alerting customers and the public to new threats and mitigation tactics, enabling us to quickly incorporate protection into our products, and stepping in to help organizations with incident response, threat hunting, compromise assessments and more. Talos can also be found securing large-scale events such as the Super Bowl, and working with government and law enforcement organizations across the globe to share intelligence.

With Cisco’s vast customer base and broad portfolio — from routers and switches to email and endpoints — Talos has visibility into worldwide telemetry. Once a threat is seen, whether it’s a phishing URL or an IP address hosting malware, detections are created and indicators of compromise are categorized and blocked across our Cisco Secure portfolio.

Talos also leverages its unique insights to help society as a whole better understand and combat the cyberattacks facing us daily. During the war in Ukraine, the group has taken on the additional task of defending over 30 critical infrastructure providers in the country by directly managing and monitoring their endpoint security.

How Talos powers XDR

The reality of security today is that organizations must be constantly ready to detect and contain both known and unknown threats, minimize impact, and keep business going no matter what happens in the cyber realm. In light of hybrid work, evolving network architectures, and increasingly insidious attacks, all organizations must also be prepared to rapidly recover if disaster strikes, and then emerge stronger. We refer to this as security resilience, and Talos plays a critical role in helping our customers achieve it.

For several years, our integrated, cloud-native Cisco SecureX platform has been delivering extended detection and response (XDR) capabilities and more. SecureX allows customers to aggregate, analyze, and act on intelligence from disparate sources for a coordinated response to cyber threats.

Through the SecureX platform, intelligence from Talos is combined with telemetry from our customers’ environments — including many third-party tools — to provide a more complete picture of what’s going on in the network. Additionally, built-in, automated response functionality helps to speed up and streamline mitigation. This way, potential attacks can be identified, prioritized, and remediated before they lead to major impact.

For XDR to be successful, it must not only aggregate data, but also make sense of it. Through combined insights from various resources, SecureX customers obtain the unified visibility and context needed to rapidly prioritize the right threats at the right time. With SecureX, security analysts spend up to 90 percent less time per incident.

Accelerating threat detection and response

One of Australia’s largest universities, Deakin University, needed to improve its outdated security posture and transition from ad hoc processes to a mature program. Its small security team sought an integrated solution to simplify and strengthen threat defense.

With a suite of Cisco security products integrated through SecureX, Deakin University was able to reduce the typical investigation and response time for a major threat down from over a week to just an hour. The university was also able to decrease its response time for malicious emails from an hour to as little as five minutes.

“The most important outcome that we have achieved so far is that security is now a trusted function.”

– Fadi Aljafari, Information Security and Risk Manager, Deakin University

Also in the education space, AzEduNet provides connectivity and online services to 1.5 million students and 150,000 teachers at 4,300 educational institutions in Azerbaijan. “We don’t have enough staff to monitor every entry point into our network and correlate all the information from our security solutions,” says Bahruz Ibrahimov, senior information security engineer at AzEduNet.

The organization therefore implemented Cisco SecureX to accelerate investigations and incident management, maximize operational efficiency with automated workflows, and decrease threat response time. With SecureX, AzEduNet has reduced its security incidents by 80 percent.

“The integration with all our Cisco Secure solutions and with other vendors saves us response and investigation time, as well as saving time for our engineers.”

– Bahruz Ibrahimov, Senior Information Security Engineer, AzEduNet

Boosting cyber resilience with Talos

The sophistication of attackers and sheer number of threats out there today make it extremely challenging for most cybersecurity teams to effectively stay on top of alerts and recognize when something requires their immediate attention. According to a survey by ESG, 81 percent of organizations say their security operations have been affected by the cybersecurity skills shortage.

That’s why Talos employs hundreds of researchers around the globe — and around the clock — to collect and analyze massive amounts of threat data. The group uses the latest in machine learning logic and custom algorithms to distill the data into manageable, actionable intelligence.

“Make no mistake, this is a battle,” said Nick Biasini, head of outreach for Cisco Talos, who oversees a team of global threat hunters. “In order to keep up with the adversaries, you really need a deep technical understanding of how these threats are constructed and how the malware operates to quickly identify how it’s changing and evolving. Offense is easy, defense is hard.”

Maximizing defense against future threats  

Earlier this year, we unveiled our strategic vision for the Cisco Security Cloud to deliver end-to-end security across hybrid, multicloud environments. Talos will continue to play a pivotal role in our technology as we execute on this vision. In addition to driving protection in our products, Talos also offers more customized and hands-on expertise to customers when needed.

Cisco Talos Incident Response provides a full suite of proactive and emergency services to help organizations prepare for, respond to, and recover from a breach — 24 hours a day. Additionally, the recently released Talos Intel on Demand service delivers custom research unique to your organization, as well as direct access to Talos security analysts for increased awareness and confidence.

Cisco Talos Supports Ukraine Through Empathy

By Mary Kate Schmermund

Cisco Talos has a long-standing relationship with Ukraine, so when Russia invaded the country earlier this year, things hit close to home. Cisco Talos leaders rallied together to provide cybersecurity threat hunting to vital infrastructure, humanitarian support and goods and services to employees and their families in the region.

Ashlee Benge, Amy Henderson and Sammi Seaman spearheaded initiatives to support and sustain Ukrainian employees and threat hunters working around-the-clock to prevent cyberattacks and remember the human element. Even in the midst of crisis, they’ve facilitated open communication, emphasized mental health and cultivated connection.

Cisco Talos’ Relationship With Ukraine

Given Ukraine’s unique position on the front lines of cyberwarfare, Cisco Talos has had a very close partnership with Ukraine. The threat intelligence team has worked with several partners in the country from a cyber threat perspective. That long standing connection is part of why Russia’s invasion of Ukraine has been felt so deeply. “Some Ukrainian team members evacuated before the invasion, others did not,” said Amy Henderson, head of strategic planning & communications. “Our teams of threat hunters have been around-the-clock hunting in the data since the invasion. They’re stopping attacks from happening.”

Cisco Talos set up Cisco Secure Endpoint on about thirty partners’ organizations and extended the offering to critical infrastructure organizations in Ukraine such as hospitals, directly monitoring Cisco Secure Endpoint, “because their people are busy doing other things right now. They can’t sit at a screen,” Henderson said.

Leading With Empathy and Open Communication

Lead of Strategic Business Intelligence Ashlee Benge directs the Ukraine Threat Hunting Task Unit which requires empathy, compassion and an awareness of the needs of forty-five threat hunters. Veteran threat hunters with decades of experience have volunteered to contribute to the team while other members of Cisco Talos have also volunteered their skill sets to the work. Benge values the distinct contributions of her team members and describes them as, “quite brilliant and very good at their jobs. Talos does a really good job of hiring good people, and so the worst thing that I could do is get in their way.” Getting in their way looks different for different team members which is why Benge has established trainings and consistent ways to evaluate that the needs of her team are being met.

The nature of such a demanding, on-going situation coupled with the team’s dedication can lead employees to work themselves into the ground. To combat this, leaders maintain weekly check-ins that include asking employees how they’re taking care of themselves and checking for signs of burnout. “When you have rest you’re at peak performance and can problem solve. But when you start burning out and get to be irritable and snappy, you’re not able to problem solve. Just step back. You’ll be in a much better head space,” Henderson advises.

Stepping back has meant rotating projects to level out activity levels and urgency. Leaders have also stepped in to ensure employees take time off and that when they’re away, they’re fully away. “When you’re in such a high intensity environment it takes two to three days just to come off of that. If you’re only taking a day here or day there, you’re not even scratching the surface of coming down. So I’ll suggest maybe you need to take a week and completely recharge,” Henderson says.

Supporting The Human Element

Team Lead of Employee Experience Sammi Seaman was heartened by Cisco’s support of Ukrainian employees including helping employees and their families out of cities and into new housing. The humanitarian focus led Seaman to ask “How else can we help? Our colleagues have had to leave their homes and they’re still trying to do work. How do I get them necessities like medicine and shampoo?”

Seaman’s empathy and collaboration within her team and with Cisco Talos leadership led to determining the highest needs including more stable internet and navigating the transport of goods directly to employees and their families through freight mail. Seaman worked with her team to ensure necessary items like medical kits could get directly to people who needed them as quickly as possible. There are also pages available coordinating housing, transportation and other forms of support.

“It’s been interesting to think about people needing medicine for various reasons and that I’m also buying Legos and castles so that the children who have been displaced have toys and things that bring them joy and allow them to be kids in this situation,” Seaman said.

As Seaman prepared more boxes to ship, an employee shared a photograph of his daughter with some of the things Seaman had sent. “I just started crying. It was such a relief.” A relief she wanted to share, leaving the boxes for a moment to connect with other team members around the positive impact of their hard work.

“Despite all of these things that are happening around us that are horrific and awful and things that shouldn’t be happening, there are still things that we can celebrate. We’re still humans who have feelings, relationships, milestones and holidays.” – Sammi Seaman

Remembering children also became important during spring holidays. Through asking employees if they celebrated Easter and if they’d like Easter baskets, she learned that many employees celebrated traditional Orthodox Ukrainian Easter and would appreciate the baskets.

Seaman’s colleague researched what people in Ukraine typically put in their Easter baskets and together they made the baskets, boxed them up and shipped them. “The baskets weren’t a necessity but were nice to remind people that despite all of these things that are happening around us that are horrific and awful and things that shouldn’t be happening, there are still things that we can celebrate. We’re still humans who have feelings, relationships, milestones and holidays.”

Mental Health and Self-Care Matter

Outside of work, Benge competes as an Olympic weightlifter. After months of training, her first national level meet was scheduled to happen early into the war in Ukraine. She considered withdrawing given the 24/7 nature of Cisco Talos’ response. However, “only because of the support of those around me,” Benge decided to compete—while working from her phone in the warm up room between lifts. The physical movement allows Benge to manage her mental health and stress while modeling self-care for the team: “If I can’t be my own best self, then the people around me can hardly be expected to do the same.”

Self-care and mental health are so important to the team that Henderson and Benge recently joined their colleagues, Matt Olney, the director of threat intelligence and interdiction, and Strategic Communications Leader Mitch Neff on a Cisco Secure podcast about mental health. The conversation illuminated the importance of reaching out for help, utilizing support systems such as those provided by Cisco and talking to someone including a therapist.

“Using those types of resources is a valuable thing, particularly when managing very high levels of stress and anxiety that come with cybersecurity. No matter what kind of support it is that we need, it’s important to take that time and recognize that it’s valuable to invest in your own mental health,” Benge stated.

Seaman shared that because it can be hard to ask for help or delegate, when she does, she gives herself a pat on the back. She advises that especially in crisis situations it’s important to remember that while things need to get done, it’s not entirely on you to get those things done. “The leadership at Cisco Talos has really emphasized that you’re not alone. The employee assistance program has been a great resource and I’ve got a therapist that I talk to about these things and make sure that I’m taking care of myself so that I can continue to take care of others.”

The team’s bond and purpose run deep. We care deeply about everyone that we work with. It’s okay to not be on at all times. It’s okay to feel sad and it’s okay to feel anxious. One of the things that I’ve loved about working with Cisco Talos, especially during these more difficult things, is that everybody’s got your back and they make it a safe space to share those feelings. I truly feel like the people I work with are like my family. We’re curated an environment where we can all talk about what we’re going through.”

McAfee 2022 Consumer Mobile Threat Report

By McAfee

We’re excited to bring you the latest edition of the McAfee 2022 Consumer Mobile Threat Report. After all, when you know the challenges you face, it’s easier to be confident online. In this blog, we’ll take a closer look at some leading examples of techniques that cybercriminals are using to trick or defraud you via your mobile phone. These examples are some of the more sophisticated attacks, using real logos, quality graphics, and personalized messages. We hope this provides a useful resource for protecting your digital life, mobile devices, and personal information so that you can enjoy a safe life online with your family. 

Cybercriminals Take Their Scams to the Next Level

Cybercriminals are upping their game, using personal information and high-quality graphics to make their malware look like legitimate apps or official messages. Because these attacks are successful at defrauding significant numbers of mobile users out of their money and information, more criminals will jump on this approach or expand their malicious campaigns. Let’s take a look at some of the different techniques being used by scammers to fool mobile users.  

Smishing looks friendly but is just the opposite

Mobile smishing (aka phishing text messages) are attacks using personalized greetings in text messages that pretend to be from legitimate organizations to appear more credible. These messages often link to websites with authentic logos, icons, and other graphics, prompting the user to enter personal information or download an app. Users should be extra careful about text messages from unknown sources and should go directly to the organization’s website to validate requests. 

Mobile gaming scams pose as gamer help and cheating tools

Cheating tools and hacking apps are popular ways to get extra capabilities in mobile games. Criminals are exploiting this by promoting game hacking apps that include malicious code on legitimate messaging channels. If installed, the malware steals account credentials for social media and gaming accounts. Gamers should use caution when installing game hacks, especially if they request superuser permissions. 

Crypto is popular and so are scams targeting it

Cryptocurrencies are providing new opportunities for mobile device attacks. The latest ploy is phony apps that promise to mine coins in the cloud for a monthly fee. Fake reviews and a low cost make them sound too good to be true—and they are. These apps just take the money without doing any coin mining. With no actual malicious code, these apps are hard to detect, so users should be suspicious of being promised hundreds or thousands of dollars of crypto coins for just a few dollars a month. 

Watch out for fake messaging apps

Another attack uses a variety of fake apps with slick graphics to trick users into premium subscriptions. Hundreds of these apps promise features such as mobile games or photo editing and are supported by plenty of fake five-star reviews. When installed, the apps ask for the user’s phone number and verification PIN and use them to sign up for premium text services that direct payments to the criminals. Users should read reviews looking for vague statements, repetitive wording, and a mix of five-star and one-star ratings. For a deeper dive into the scams, be sure to view full report.

How to Protect Yourself 

While threat tactics continue to change as criminals adapt and respond to detection and enforcement techniques, there are a few steps users should take to limit their exposure and risk. 

Stay on the app stores

While some malicious apps do make it through the app store screening process, most of the attack downloads appear to be coming from social media, fake ads, and other unofficial app sources. Before downloading something to your phone, do some quick research about the source and developer. Many of these scams have been flagged by other people. 

Watch requests for settings and permissions

Many malicious apps get the access they need by asking the user to grant them permission to use unrelated privileges and settings. When installing a new app, take a few moments to read these requests and deny any that seem unnecessary, especially for superuser access and accessibility services.  

Update your software

Developers are actively working to identify and address security issues. Both operating systems and apps should be frequently updated so that they have the latest fixes and security protections. 

Be wary of too many five-star reviews

Cybercriminals often flood their Google Play apps with fake five-star reviews. Many fake or malicious apps only have a mix of five-star and one-star reviews. The five-star ones typically have vague statements and repetitive wording, giving clues that they are submitted by bots. Compare them to the one-star reviews for insight on the app’s real capabilities. 

Pay attention if your phone is acting funny

Devices that are behaving unusually may just have a basic tech issue but it can also be a sign of being hacked. Follow up when something is not quite right, check recent changes or contact tech support from the mobile device vendor or security software provider. 

Use security software

Comprehensive security software across all devices, whether they are computers, tablets, or smartphones, continues to be a strong defensive measure to protect your data and privacy from cyber threats. 

We hope this report helps you stay on the lookout for these and other mobile threats so you can safely and confidently enjoy your life online.

5 Ways to Protect Your Online Privacy

By McAfee

When you open your laptop or your mobile device, what is the first thing you do? Do you head to your favorite social media site to skim the latest news, or do you place your weekly grocery delivery order? No matter what your daily online habits are, even the slightest degree of caution can go a long way in staying secure online.  

That’s because hackers are experts at hiding malware in your everyday online routines, or even infiltrating your cookies to steal login information and learn about your personal preferences.  

According to a StatsCan Canadian internet use survey, six out of ten internet users reported experiencing a cybersecurity incident. There are many hoops to jump through when navigating the digital landscape. By taking the necessary steps to remedy vulnerabilities in your digital activity, you can dramatically improve your online protection.  

Three online threats to watch out for  

Cybercriminals take advantage of online users through routine avenues you would not expect. Here are three common ways that cybercriminals eavesdrop on online users.  

1.  Adware 

Adware, or advertising-supported software, generates ads in the user interface of a person’s device. Adware is most often used to generate revenue for the developer by targeting unsuspecting online users with personalized ads paid by third parties. These third parties usually pay per view, click, or application installation.   

Though not always malicious, adware crosses into dangerous territory when it is downloaded without a user’s consent and has nefarious intent. In this case, the adware becomes known as a potentially unwanted application (PUA) that can remain undetected on users’ devices for long periods of time. According to a report by the Cybersecure Policy Exchange, an unintentionally installed or downloaded computer virus or piece of malware is one of the top five cybercrimes that Canadians experience. The PUA can then create issues like frequent crashes and slow performance.   

Users unknowingly download adware onto their device when they download a free ad-supported program or visit a non-secure site that does not use the Hypertext Transfer Protocol Secure (HTTPS) to encrypt online communication.   

2.  Malvertising 

Hackers also use invasive tactics known as ad injections, where they inject ads with malicious code for increased monetary gain. This is a practice known as “malvertising.” If a user clicks on a seemingly legitimate and well-placed ad, they risk exposing themselves to numerous online threats. These ads can be infected with malware such as viruses or spyware. For example, hackers can exploit browser vulnerabilities to download malware, steal information about the device system, and gain control over its operations. Hackers can also use malvertising to run fraudulent tech support scams, steal cookie data, or sell information to third-party ad networks.  

3.  Autofill 

Another vulnerability that many may not realize is their browser’s built-in autofill functions. As tempting as it is to use your browser’s autofill function to populate a long form, this shortcut may not be safe. Cybercriminals have found ways to capture credentials by inserting fake login boxes onto a web page that users cannot see. So, when you accept the option to autofill your username and password, you are also populating these fake boxes.   

Tips for rethinking your online habits  

Take a proactive approach to your digital protection the next time you are browsing the internet by reassessing your online habits. Check out these five tips to ensure you are staying as safe as possible online.  

1.  Clear your cookies on your browser 

Cookie data can contain anything from login information to credit card numbers. Cybercriminals looking to exploit this information can hijack browser sessions to pose as legitimate users and steal cookies as they travel across networks and servers. As a result, it is essential for online users to regularly clear out their cookies to better protect their information from falling into the wrong hands. Navigate to your browser’s history, where you can wipe the data associated with each browser session, including your cookies.   

2.  Use a reliable password manager 

Clearing your browser’s cookie data will also remove your saved logins, which is why leveraging a password manager can make it easier to access regularly visited online accounts.   

Many browsers come with a built-in password generator and manager; however, it is better to entrust your logins and password to a reputable password manager. Browser password managers are not as secure as password managers, because anyone who has access to your device will also access your online information. A password manager,  provides a more secure solution since it requires you to log in with a separate master password. A password manager also works across various browsers and can generate stronger passwords than those created by your browser.   

3.  Adjust browser privacy settings 

In addition to clearing cookie data, users should adjust their browser settings to ensure their online sessions remain private.   

Another option is to access the internet in Private Browsing Mode to automatically block third-party tracking, making it a quick and easy option to ensure private browsing. Users can also enable the “do not track” function of their browser to prevent third-party tracking by advertisers and websites. Additionally, you can adjust your browser settings to block pop-up ads and control site permissions, such as access to cameras and locations.   

4.  Use an ad blocker 

Ad blockers suppress unwanted and potentially malicious ads to ensure a safer browsing experience. Ad blockers can also make it easier to view page layout by removing distracting ads and optimizing page load speed. Additionally, they prevent websites from tracking your information that third parties can sell.  

5.  Leverage a reputable security solution  

Deploying a security solution like McAfee+ Ultimate ensures the safest internet browsing experience through a holistic approach for threat detection, protection, and remediation. Equipped with a password manager, antivirus software, and firewall protection, users can effectively sidestep online threats while browsing the internet. Moreover, it includes comprehensive privacy and identity protection, such as our Personal Data Cleanup, dark web monitoring, credit monitoring, along with ways you can quickly Lock or freeze your credit file to help prevent accounts from being opened in your name. 

Take action to ensure safe browsing  

Your online behavior can say a lot about you so make sure you safeguard your internet protection. Whether it is through malvertising or invisible forms, hackers can glean information to paint a picture of who you are to target you through deceptive tactics. Cybercriminals are always looking for vulnerabilities which is why assessing your online habits sooner rather than later is a critical first step to smarter online browsing.

Protect Your Digital Wellness: Don’t Post Your Vaccination Card Online 

Think Twice Before Posting Your Vaccination Card on Social Media

After much anticipation, you finally get a notification that you’re eligible to receive your COVID-19 vaccine. Upon getting your first dose, you may be eager to celebrate by sharing a picture of your vaccination card on social media. After all, many of your peers have been doing the same. However, these posts could actually put your online privacy and personal information at risk. While you want to share the good news, experts warn that scammers could potentially exploit the information on your card.

How Vaccine Selfies Could Affect Your Online Security

With more people becoming eligible to receive the COVID-19 vaccine, there has been a surge in social media posts featuring peoples’ vaccine cards. However, the Better Business Bureau stated that posting photos of your card can give criminals the data they need to create and sell fake vaccination cards. Not only do vaccine cards remind you of when your next appointment is, but they also contain important personal information such as your name, date of birth, and when and where you were vaccinated.

Currently, these cards are the only proof that people have that they’ve been vaccinated. While there is still uncertainty around the next phase of the pandemic and when life will return to “normal,” it’s possible these cards could be what gets you into a restaurant or on an airplane. If you post your vaccination card on social media, scammers could potentially forge your card and use it as their own pass into public places or use it to receive a second dose. Publicly posting medical information could also void your HIPAA protections. Furthermore, cybercriminals could significantly profit from your personal information since health care records sell for more than Social Security and credit card numbers on the dark web.

Protect Your Digital Wellness

Your digital wellness is just as important as your physical wellness, so protecting your online data is crucial. It’s a good rule of thumb not to post photos with your name and other identifiable information on the internet. Although it may be tempting to post your vaccination card on social media, consider these tips to help protect your online security:

1. Check your privacy settings

Think about who you want to share the good news with and what social media platform would be best for this. Create private groups or carefully select which followers can see your posts. Then, verify that you’ve updated your privacy settings accordingly. This will prevent scammers from lurking on your posts and extracting your personal information.

2. Find alternatives to share that you’re vaccinated

Instead of posting a photo of your vaccine card, share a picture of yourself outside the vaccination center. If your vaccination center provides “I got vaccinated” stickers, you can post a picture of that as well.

Taking steps towards protecting your digital well-being is just as important as taking steps towards protecting your physical health. By following these steps, you can help ensure that your online security will not be jeopardized by celebrating your vaccination.

Check up on Your Virtual Safety: Tips for Telehealth Protection

By Jean Treadwell
Telemedicine visit

Check up on Your Virtual Safety: Tips for Telehealth Protection

In a poll conducted by the Canadian Medical Association, nearly half of Canadians have used telehealth services since the start of the pandemic. Additionally, in a recent McAfee study, we found that 21% of Canadians have used the internet for a doctor visit in 2020, and 28% said that such online visits will become a part of their routine moving forward Telehealth, or virtual care. This includes clinical services delivered remotely via electronic communications, such as videoconferencing, mobile apps and remote patient monitoring technology. Many of us have readily accepted these medical services out of necessity, as COVID have limited in-person hospital visits.

Hackers are taking advantage of the rise in virtual health services and exploiting their vulnerabilities to steal sensitive medical records. These vulnerabilities are the result of bigger issues stemming from obscure patient health information regulations and health care system budgetary constraints.

Understanding the risks associated with telehealth is the first step to securing your online safety during your virtual doctor’s visits.

Why Cybercriminals Target Health Care

At the onset of the pandemic, the number of reported Canadian cyberattacks jumped 50% from Q4 2019 to Q1 2020. Health care is one of the most targeted industries for cyberattacks. One attack even compromised the organization that manages Ontario’s medical records. Health care is such a highly targeted industry because it holds a wealth of information that fetches a high price on the dark web. Experts say medical records are more valuable than credit card details due to the amount of vital information stored in them, such as birth dates and patient ID numbers. Hackers can then hold this information for ransom or use it to steal your identity. Further, cybercriminals see health care institutions as easy targets. Canadian health care IT departments have insufficient budgets and are ill-prepared to handle the rising threats.

Canada also does not have federal guidelines governing virtual care and patient health information. Rather, health care providers and virtual care platforms are limited to the broad guidelines outlined by the Personal Information Protection and Electronic Documents Act (PIPEDA). As these are not digital security specific purpose defined guidelines and requirements, it makes it more difficult for health care providers and telehealth companies to protect patient data.

Telehealth Risks

Telehealth makes care accessible to everyone; unfortunately, if you’re not careful, telehealth also opens the door for hackers. Hackers can infiltrate the technology used for online doctor’s appointments, because video conferencing technologies have several security flaws. From there, hackers can disrupt calls, eavesdrop and steal your private health information.

The advent of telehealth services has also prompted an increase in emails. Since patients may be expecting emails from their doctor, they may let their guard down and fall victim to phishers posing as a health care organization.

Take Control of Your Health Privacy

Prepare for your next virtual doctor’s appointment with these best practices to secure your virtual safety.

Ask the right questions

Before heading into your next telehealth appointment, ask your health care provider the right questions to online understand what risks you may face. Ascertaining this information will help you understand what actions you need to take to mitigate the risk on your end, like staying alert for eavesdroppers or finding alternative ways to confirm personal information. Here are some questions you can ask:

  • “Do you record your sessions?”
  • “Do you share information with third parties?”
  • “How is my data being used?”
  • “What security measures does your telehealth platform implement? Does it use the highest encryption levels or employ multi-factor authentication?”

Beware of phishing

Phishing is a common tactic hackers use to access private health information and trick users into downloading malware. Beware of seemingly official emails under the guise of your health care provider asking for payment information or prompting you to take immediate action. If the email logo doesn’t look right, the message is poorly written, or the URL displayed doesn’t match the one that’s linked, then it’s likely a phishing scam.

Contact your health care provider before verifying sensitive information online, such as payment details or document transfer methods, to avoid falling victim to phishing. We recommend logging into your healthcare provider’s official website or app to confirm pertinent healthcare information as well. If you accidentally reply to a phishing email, perform a full malware scan on your device to ensure your private information remains secure.

Keep medical apps up to date

It’s important to keep telehealth applications up to date to benefit from the latest bug fixes and security patches. This includes apps belonging to your IoT devices, such as glucose monitors, blood pressure monitors or other network-enabled diagnostic devices. These devices represent more entry points that hackers can infiltrate, making it especially critical to keep them up to date and close any security loopholes.

Elevate your authentication methods

Get creative with your telehealth portal password, or better yet, use a security solution that includes a password management system. McAfee Total Protection includes a robust password management system that creates and saves strong passwords across all your accounts in one centralized location.

Ensure you’re using a telehealth platform that leverages multi-factor authentication, so even if a hacker were to acquire your password, there’s an added layer of security they won’t be able to bypass.

Defend against prying eyes by using a VPN

It’s always best to use a virtual private network (VPN) when conducting activities online, and medical visits are no exception. Using a VPN like McAfee Safe Connect VPN will ensure your data is encrypted and your private health information stays between you and your doctors. A VPN is especially important if you’re connecting from a network other than your password-protected home Wi-Fi.

Take Care of Your Physical and Virtual Health

Medical services are just one of many activities that have turned virtual due to the pandemic. Keep in mind these new virtual outlets come with elevated risks. Hackers are taking advantage of software vulnerabilities and taking victims unaware through social engineering tactics to steal sensitive personal information. Remember to secure your online health by taking a proactive stance against malicious threats so you can focus on your physical health during your telehealth visits.

What Is a DDoS Attack and How to Stay Safe from Malicious Traffic Schemes

By McAfee
What is a DDoS attack?

What Is a DDoS Attack and How to Stay Safe from Malicious Traffic Schemes

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.

DDoS Attacks Are on the Rise

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.

Personal Devices Become DDoS Attack Soldiers

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.

Why DDoS Launches Are Often Successful

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.

3 Ways to Prevent Your Devices from Being Recruited

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:

  1. Secure your router: Your Wi-Fi router is the gateway to your network. Secure it by changing the default password. If you’ve already thrown out the instructions for your router and aren’t sure how to do this, consult the internet for instructions on how to do it for your specific make and model, or call the manufacturer. And remember, protection can start within your router, too. Solutions such as McAfee Secure Home Platform, which is embedded within select routers, help you easily manage and protect your network.
  2. Change default passwords on IoT devices: Many Internet of Things (IoT) devices, smart objects that connect to the internet for increased functionality and efficiency, come with default usernames and passwords. The very first thing you should do after taking your IoT device out of the box is change those default credentials. If you’re unsure of how to change the default setting on your IoT device, refer to setup instructions or do a bit of research online.
  3. Use comprehensive security: Many botnets are coordinated on devices without any built-in security. Comprehensive security solutions, like McAfee Total Protection, can help secure your most important digital devices from known malware variants. If you don’t have a security suite protecting your devices, take the time to do your research and commit to a solution you trust.

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.

Keep Remote Classes Safe and in Session: What You Need to Know About Netop Vision Pro

By Judith Bitterli

Keep Remote Classes Safe and in Session: What You Need to Know About Netop Vision Pro

Distance and hybrid learning environments are now the norm, and it remains to be seen if or when this will change. To adapt, many schools have adopted new software to support remote classroom management.

One such platform is Netop Vision Pro, a student monitoring system that helps teachers facilitate remote learning. The software allows teachers to perform tasks remotely on students’ computers, such as locking their devices, blocking web access, remotely controlling their desktops, running applications, and sharing documents. However, the McAfee Advanced Threat Research (ATR) team recently discovered multiple vulnerabilities with Netop Vision Pro that could be exploited by a hacker to gain full control over students’ computers.

Let’s dive into these vulnerabilities and unpack how you can help protect your students in the virtual classroom.

How We Identified Netop Vision Pro Vulnerabilities

Just like a school science project, our researchers created a simulation to test their hypothesis regarding the potential software bugs. The McAfee ATR team set up the Netop software to mimic a virtual classroom with four devices on a local network. Three devices were appointed as students, and one was designated as the teacher. During the setup, the team noticed that there were different permission levels between student profiles and teacher profiles. They decided to see what would happen if they targeted a student profile, since this would likely be the avenue a hacker would take since they could cause more damage. With their experiment set up, it was time for our researchers to get inside the mind of a cybercriminal.

While observing the virtual classroom, the ATR team discovered that all network traffic — including sensitive information like Windows credentials — was unencrypted with no option to turn encryption on during configuration. They also noticed that a student connecting to a classroom would unknowingly begin sending screenshots to the teacher.

Furthermore, the ATR team noticed that teachers would send students a network packet (a small segment of internet data) prompting them to connect to the classroom. With this information, the team was able to disguise themselves as a teacher by modifying their code. From there, they explored how a hacker could take advantage of the compromised connection.

The McAfee ATR team turned their attention to Netop Vision Pro’s chat function, which allows teachers to send messages or files to a student’s computer, as well as delete files. Any files sent by a teacher are stored in a “work directory,” which the student can open from an instant message (IM) window. Based on the team’s discovery that a hacker could disguise themselves as a teacher, it became clear that hackers could also use this functionality to overwrite existing files or entice an unsuspecting student to click on a malicious file.

The Risks of Netop Vision Pro Vulnerabilities

Of course, remote learning software is necessary right now to ensure that our children stay on top of their studies. However, it’s important that we educate ourselves on these platforms to help protect our students’ privacy. While the Netop Vision Pro student screen shares may seem like a viable option for holding students accountable in the virtual classroom, it could allow a hacker to spy on the contents of the students’ devices. While the functionality allows teachers to monitor their students in real-time, it also puts their privacy at risk.

If a hacker is able to impersonate a teacher with modified code, they could also send malicious files that contain malware or other phishing links to a student’s computer. Netop Vision Pro student profiles also broadcast their presence on the network every few seconds, allowing an attacker to scale their attacks to an entire school system.

Finally, if a hacker is able to gain full control over all target systems using the vulnerable software, they can equally bridge the gap from a virtual attack to the physical environment. The hacker could enable webcams and microphones on the target system, allowing them to physically observe your child and their surrounding environment.

Our Response to the Identified Vulnerabilities

Our researchers reported all vulnerabilities discovered to Netop and heard back from the company shortly after. In the latest software release 9.7.2, Netop has addressed many of the issues the McAfee ATR team discovered. Students can no longer overwrite system files, which could be used take control of the student machine. Additionally, Windows credentials are now encrypted when being sent over the network. Netop also told McAfee that they have plans to implement full network encryption in a future update, which will prevent an attacker from easily monitoring student’s screens and prevent them from being able to emulate a teacher.

While Netop works to remedy these issues internally, there are some critical steps parents can take to help protect and empower your children in the virtual classroom. Check out the following tips to bring you and your family peace of mind while using third-party education platforms:

1. Use a dedicated device for remote learning software

If your student is required to use Netop Vision Pro or other third-party software while distance learning, have them use this technology on a device strictly used for educational purposes. If the software contains any bugs, this prevents other important accounts used for online banking, emails, remote work, etc. from becoming vulnerable to the software risks.

2. Use comprehensive security software

It’s important to keep in mind that Netop Vision Pro was never intended to be internet-facing or taken off a school network. Let’s look at this scenario through the eyes of a hacker: they will likely try to take advantage of these vulnerabilities by delivering a malicious payload (parts of cyberattacks that can cause harm) or phishing attempts. To protect your students from these threats, utilize a comprehensive security solution like McAfee® Total Protection, which helps defend your entire family from the latest threats and malware while providing safe web browsing.

3. Keep an open line of communication with your student’s school

Educators want to keep their students’ best interest and safety in mind, so talk to your child’s teacher or principal if you ever have concerns regarding the software they are using for distance learning. If your student is required to use Netop, ensure that the teacher or principal is aware of the vulnerabilities listed above so they can be sure to administer the necessary software updates to keep your child and their classmates safe.

4. Use a webcam cover

A simple yet affective way to prevent hackers from spying on you and your family is to use a webcam cover for when class is not in session. Instruct your student to place a cover over their camera when they are not using it to bring you and your student greater peace of mind.

Attention Android Users: This Free VPN App Leaked the Data of 21 Million Users

Attention Android Users: This Free VPN App Leaked the Data of 21 Million Users

To live our digital lives to the fullest, we rely on a variety of technologies to support our online activities. And while some apps and devices are meant to make certain tasks more convenient or provide us with greater security, others simply offer a false sense of security and could potentially lead to online misfortune. One such platform is SuperVPN. While users may applaud themselves for using a VPN to protect their privacy, this Android app is unfortunately spilling their secrets without their knowledge.

Let’s unpack how SuperVPN works and its recent involvement in a data breach.

SuperVPN or Super Villain?

VPNs (virtual private networks) are intended to create a secure tunnel between your device and the internet, offering you privacy and freedom from IP-based tracking. It protects your identity and financial information by encrypting, or scrambling, the data that flows through the tunnel, and can mask your true location, making it appear as though you are connecting from somewhere else. VPN apps have become much more popular in recent years as our awareness around privacy and security has grown. But, such is the case with all apps, it’s important to do your research before you select one to install on your phone.

According to Forbes, critical security warnings around the app SuperVPN surfaced last year. They reported research stating that 105 million people might have had their credit card details stolen, and that hackers could intercept messages between the user and provider. As of last Friday, someone leaked three databases on a popular hacking forum that purportedly contained user credentials and device data stolen from three different Android VPN services: SuperVPN, considered one of the most dangerous VPNs on Google Play with 100 million installs, GeckoVPN (10 million installs), and ChatVPN (50,000 installs). This breach exposed the data of 21 million users, including names, email addresses, usernames, payment data, device information, and even location data logs —  a major red flag for a VPN.

You Can’t Put a Price on Data Protection

Although a free VPN might seem like an ideal solution at first, there are multiple consequences that could potentially put your online safety in jeopardy. Since free VPNs are not making money directly from their users, many make revenue indirectly, through advertising. This means that not only will you be bombarded with ads, but you’re also exposed to tracking and malware. In fact, one study of 283 free VPN providers found that 72% included trackers. Beyond the frustration of ads, slowness, and upgrade prompts is the fact that some free VPN tools include malware that can put your sensitive information at risk. The same study found that 38% of the free VPN applications in the Google Play Store were found to have malware and some even stole the data off of users’ devices, similar to SuperVPN.

If you choose a verified, paid VPN service, however, you’ll enjoy a plethora of benefits including unlimited bandwidth, speedy performance, protection across multiple devices, and much more. Aside from choosing a premium VPN service, following these tips will help you stay secure against SuperVPN and others like it and protect your daily online communications:

1. If you have SuperVPN, uninstall it

Delete SuperVPN from your device as soon as possible. There are at least six other apps like SuperVPN, with identical descriptions and logos from different creators on Google Play Store. Steer clear of downloading these apps altogether to avoid any cyber misfortune.

2. Do your research

While some malicious apps do make it through the app store screening process, most attack downloads appear to stem from social media, fake ads, and other unofficial app sources. Before downloading an app to your device, do some quick research about the origin and developer.

3. Read app reviews with a critical eye

Reviews and rankings are still a suitable method of determining whether an app is legitimate. However, watch out for assessments that reuse repetitive or straightforward phrases, as this could be a sign of a fraudulent review.

4. Place a fraud alert

If you suspect that your data might have been compromised, place a fraud alert on your credit. This not only ensures that any new or recent requests undergo scrutiny, but also allows you to have extra copies of your credit report so you can check for suspicious activity.

5. Upgrade to holistic security for your peace of mind

A comprehensive security suite like McAfee Total Protection includes our McAfee® Safe Connect standalone VPN with auto-renewal and takes the worry out of connecting, so you can focus on what’s important to you.

How to Spot, and Prevent, the Tax Scams That Target Elders

By Judith Bitterli
tax scams that target seniors

How to Spot, and Prevent, the Tax Scams That Target Elders

Elder scams cost seniors in the U.S. some $3 billion annually. And tax season adds a healthy sum to that appalling figure.

What makes seniors such a prime target for tax scams? The Federal Bureau of Investigation (FBI) states several factors. For one, elders are typically trusting and polite. Additionally, many own their own home, have some manner of savings, and enjoy the benefits of good credit—all of which make for an ideal victim profile.

Also according to the FBI, elders may be less able or willing to report being scammed because they may not know the exact way in which they were scammed, or they may feel a sense of shame over it, or even some combination of the two. Moreover, being scammed may instill fear that family members will lose confidence in their ability to look after their own affairs.

If there’s one thing that we can do for our elders, it’s help them raise their critical hackles so they can spot these scams and stop them in their tracks, particularly around tax time. With that, let’s see how crooks target elders, what those scams look and feel like, along with the things we can do to keep ourselves and our loved ones from getting stung.

The IRS imposter scam

The phone rings, and an assertive voice admonishes an elder for non-payment of taxes. The readout on the caller ID shows “Internal Revenue Service” or “IRS,” the person cites an IRS badge number, and the victim is told to pay now via a wire transfer or prepaid gift card. The caller even knows the last four digits of their Social Security Number (SSN). This is a scam.

The caller, and the claim of non-payment, are 100 percent bogus. Even with those last four digits of the SSN attempting to add credibility, it’s still bogus. (Chances are, those last four digits were compromised elsewhere and ended up in the hands of the thieves by way of the black market or dark web so that they could use them in scams just like these.)

Some IRS imposter scams take it a step further. Fraudsters will threaten victims with arrest, deportation, or other legal action, like a lien on funds or the suspension of a driver’s license. They’ll make repeated calls as well, sometimes with additional imposters posing as law enforcement as a means of intimidating elders into payment.

The IRS will never threaten you or someone you know in such a way.

In fact, the IRS will never call you to demand payment. Nor will the IRS ever ask you to wire funds or pay with a gift card or prepaid debit card. And if the IRS claims you do owe funds, you will be notified of your rights as a taxpayer and be given the opportunity to make an appeal. If there’s any question about making payments to the IRS, the IRS has specific guidelines as to how to make a payment properly and safely on their official website.

It’s also helpful to know what the IRS will do in the event you owe taxes. In fact, they have an entire page that spells out how to know it’s really the IRS calling or knocking at your door. It’s a quick read and a worthwhile one at that.

In all, the IRS will contact you by mail or in person. Should you get one of these calls, hang up. Then, report it. I’ll include a list of ways you can file a report at the end of the article.

Tax scams and robocalls

Whether it’s a disembodied voice generated by a computer or a scripted message that’s been recorded by a person, robocalls provide scammers with another favorite avenue of attack. The approach is often quite like the phone scam outlined above, albeit less personalized because the attack is a canned robocall. However, robocalls allow crooks to cast a much larger net in the hopes of illegally wresting money away from victims. In effect, they can spam hundreds or thousands of people with one message in the hopes of landing a bite.

While perhaps not as personalized as other imposter scams, they can still create that innate sense of unease of being contacted by the IRS and harangue a victim into dialing a phony call center where they are further pressured into paying by wire or with a prepaid card, just like in other imposter scams. As above, your course of action here is to simply hang up and report it.

IRS email scams and phishing attacks

Here’s another popular attack. An elder gets an unsolicited email from what appears to be the IRS, yet isn’t. The phony email asks them to update or verify their personal or financial information for a payment or refund. The email may also contain an attachment which they are instructed to click and open. Again, all of these are scams.

Going back to what we talked about earlier, that’s not how the IRS will contact you. These are phishing attacks aimed at grifting prized personal and financial information that scammers can use to commit acts of theft or embezzlement. In the case of the attachment, it very well may contain malware that can do further harm to their device, finances, or personal information.

If you receive one of these emails, don’t open it. And certainly don’t open any attachments—which holds true for any unsolicited email you receive with an attachment.

Preventing tax scams from happening

Beyond simply knowing how to spot a possible attack, you can do several things to prevent one from happening in the first place.

Physical security

First let’s start with some good, old-fashioned physical security. You may also want to look into purchasing a locking mailbox. Mail and porch theft are still prevalent, and it’s not uncommon for thieves to harvest personal and financial information by simply lifting it from your mailbox.

Another cornerstone of physical security is shredding paper correspondence that contains personal or financial information, such as bills, medical documents, bank statements and so forth. I suggest investing a few dollars on an actual paper shredder, which are typically inexpensive if you look for a home model. If you have sensitive paper documents in bulk, such as old tax records that you no longer need to save, consider calling upon a professional service that can drive up to your home and do that high volume of shredding for you.

Likewise, consider the physical security of your digital devices. Make sure you lock your smartphones, tablets, and computers with a PIN or password. Losing a device is a terrible strain enough, let alone knowing that the personal and financial information on them could end up in the hands of a crook. Also see if tracking is available on your device. That way, enabling device tracking can help you locate a lost or stolen item.

Digital security

There are plenty of things you can do to protect yourself on the digital front too. Step one is installing comprehensive security software on your devices. This will safeguard you in several ways, such as email filters that will protect you from phishing attacks, features that will warn you of sketchy links and downloads, plus further protection for your identity and privacy—in addition to overall protection from viruses, malware, and other cyberattacks.

Additional features in comprehensive security software that can protect you from tax scams include:

  • File encryption, which renders your most sensitive files into digital gibberish without the encryption key to translate them back.
  • A digital file shredder that permanently deletes old files from your computer (simply dropping them into the desktop trashcan doesn’t do that—those files can be easily recovered).
  • Identity theft protection, which monitors the dark web for your personal info that might have been leaked online and immediately alerts you if you might be at risk of fraud.

And here’s one item that certainly bears mentioning: dispose of your old technology securely. What’s on that old hard drive of yours? That old computer may contain loads of precious personal and financial info on it. Look into the e-waste disposal options in your community. There are services that will dispose of and recycle old technology while doing it in a secure manner so the data and info on your device doesn’t see the light of day again.

Spot a tax scam? Report it.

As said earlier, don’t let a bad deed go unreported. The IRS offers the following avenues of communication to report scams.

  • Contact the Treasury Inspector General for Tax Administration to report a phone scam. Use their “IRS Impersonation Scam Reporting” web page. You can also call 800-366-4484.
  • Report phone scams to the Federal Trade Commission. Use the “FTC Complaint Assistant” on FTC.gov. Please add “IRS Telephone Scam” in the notes.
  • Report an unsolicited email claiming to be from the IRS, or an IRS-related component like the Electronic Federal Tax Payment System, to the IRS at phishing@irs.gov.

Stay safe this tax season!

In all, learning to recognize the scams that crooks aim at elders and putting some strong security measures in place can help prevent these crimes from happening to you or a loved one. Take a moment to act. It’s vital, because your personal information has a hefty price tag associated with it—both at tax time and any time.
