Start the New Year Right With This 3-Step Digital Detox

By McAfee

Pledging to follow healthier habits is consistently the most popular new year’s resolution. That January 1st promise looks different to everyone: snacking less often, going to the gym more often, drinking more water, drinking less soda, etc. This year, instead of a juice cleanse subscription, opt for a healthier habit that’s not an unappetizing shade of green: follow this digital detox, instead! In three easy steps, you can make great strides in improving your digital wellness. 

1. Update

There are various aspects of your digital habits that you should consider updating for a more private and safer online life. For starters, update your passwords. Do you reuse the same password for multiple online accounts? Doing so puts your personally identifiable information (PII) at great risk. For example, if a business with which you have an online shopping account is breached by a cybercriminal, your login and password combination could make it on the dark web, through no fault of your own. Then, through a brute force attack, a criminal could use that same password and username combo to walk into your banking or tax filing accounts.   

Remembering unique, complicated passwords and passphrases for your dozens of online accounts would be impossible. Luckily, there’s software that remembers them for you! It’s called a password manager, which acts as a vault for all your login information. Just remember one master password, and you can be confident in the security of your accounts and never have to deal with the hassle of forgetting passwords. 

Another aspect of updating you should adopt in 2023 is making an effort to always upgrade to the latest software updates on all your devices. The easiest way to do this is to turn on automatic updates. From there, you don’t need to take any further action! Apps and operating systems (like Apple, Android, and Windows) often release updates to patch security vulnerabilities. When you run outdated software, there’s a chance a cybercriminal could take advantage of that security gap. 

Finally, make sure that you keep updated on the latest security headlines. Consider setting up news alerts to notify you when a breach occurs at a company that you frequent or have an account with. Speed is often key in making sure that your information remains safe, so it’s best practice to have your finger on the pulse on the security news of the day. 

2. Connect

A new year digital detox can be a whole family affair. Connect with your family, anyone connected to your home network, and your elderly relatives to get everyone on the same page with security best practices. Here are some common online security snags people of all ages encounter: 

Social media oversharing.

Everyone has an oversharer on their newsfeed. Alert your family members of the dangers of posting too much about their personal life. When someone takes those “get to know you” quizzes and posts their answers, cybercriminals can use that post to take educated guesses at your passwords. Additionally, social engineers can tailor social media scams to specific people in order to increase the chances of tricking someone into sending money or sharing valuable personal or banking details. 

Falling for phishing.

While spam filters catch a lot of phishing emails, phishers are getting smarter by the day and are making their attempts more and more believable. Connect with your loved ones and make sure they know how to recognize phishing emails, texts, and social media direct messages. Telltale signs of a phishing message include:  

  • Typos and grammar mistakes 
  • Over-the-top language that makes you feel very angry, sad, or excited 
  • Harsh consequences for not replying within a short timeframe 
  • Requests for passwords or Social Security Numbers 
  • Blurry logos 

If you’re ever unsure if a message is a phishing attempt, the best course of action is to just delete it. If the “sender” is a well-known institution, follow up with a phone call using the official customer service number listed on their website. The phisher may also claim to be someone you know personally. In that case, give the loved one in question a phone call. It’s a good excuse to reconnect and have a nice conversation! 

Visiting unsafe sites.

In the quest for free streams of the latest new show or movie, people often encounter unsafe sites that hide malware, spyware or other types malicious links and programs. Some types of malware can jump from one device to others connected to the same home Wi-Fi network. That’s why it’s important to make sure everyone under your roof practices excellent digital security habits. One wrong click could sink an entire household. Consider signing up your family for a safe browsing extension that can notify you when you stray onto a risky site. So, instead of putting your device at risk during movie night, connect with your friends or loved ones over one copy of a safely and officially purchased version. 

3. Balance

As with any new health regimen, immediately zooming from zero to a hundred will likely be overwhelming and result in failure. The same goes for adopting new digital safety habits. If you try to do too much at once, all the security measures you put in place will likely get in the way of your daily online activities. The more inconvenient it is, the more likely you may be to cut corners; thus, negating all the progress you’ve made. 

Being cybersafe doesn’t mean you can’t still enjoy your connected devices to the fullest. It just means that you may need to act with more intention and slow down before volunteering personal details online or clicking on links.

2022’s Top 5 App Security Tips

By Vishnu Varadaraj

Happy National App Day! No, we don’t mean apps of the mozzarella stick and potato skin variety, but your mobile apps that let you order dinner, hail a taxi, stay connected to your friends, and entertain you for hours with silly videos. While they’re undoubtedly useful, mobile apps are also a weak spot in some people’s digital safety. Cybercriminals take every chance they get to trick people through all kinds of technology, and mobile apps are no exception. 

To celebrate National App Day, here are a few tips to keep your mobile and your personally identifiable information (PII) safe. 

Prominent 2022 Mobile App Security Events 

Did you know that there are hundreds of apps on the Android and Apple app stores whose only aim is to steal your passwords? In 2022, Meta identified more than 400 fake apps disguised as various utilities that targeted users to weasel Facebook login and password combinations.1 Malicious apps also regularly masquerade as photo editors and wallpapers but their real purpose is to run malware in the background of the mobile device, such as this Squid Game app from 2021. 

Little-known apps aren’t the only ones you have to be wary of either. The biggest companies are also falling to cybercrime. For instance, more details recently came to light about a breach at Uber that leaked the PII of 57 million users. Plus, the popular mobile payment service, Cash App had the personal details of 8.3 million current and former users leaked.2 

5 App Security Tips to Bring With You into 2023 

To keep your cellphone free of malicious software and your PII and password secure, take these five mobile security tips with you into the new year. 

1. Delete old apps.

The new year is as good a time as any to unload any unnecessary baggage, emotional, literal, or in this case, digital. Go through your phone and delete the apps you haven’t used in the last six months. Make sure to completely delete your account with that app and not just hide it from your homepage. The smaller your digital footprint, the less at risk your PII is of being compromised in a breach. 

2. Carefully vet new apps.

Before you download any new app, it’s a good idea to conduct some background research on it. How many detailed reviews does it have? Who is the app developer? A phony app usually reveals itself through its lack of reviews. Consider apps with less than 50 reviews fishy. Skim the reviews for specific details and typos. If it’s lacking in detail but brimming with typos and grammatical mistakes, it could signal a fake. This research should take about five minutes, so don’t worry; it shouldn’t be too much of an inconvenience, and that time will be well spent. 

3. Stay on top of security news.

Just like it’s a good idea to keep on top of global news, set up news alerts for cybersecurity breaches. If a company falls to a cybercriminal, the alert will give you the valuable time you need to act quickly to either delete your account or change your password. 

4. Use unique passwords.

For every online account, it is essential to create a unique password or passphrase. That way, if you do get hacked through an app or get tricked by a fake one, you don’t have to worry about cybercriminals using that password to walk into your other accounts. Password managers are an excellent way to keep all your passwords secure and free up your brain space for things other than dozens of passwords. 

5. Share as few personal details as possible.

When you sign up for a new app, you can expect to give it a username, a password, and maybe your first name; however, if it has optional fields for your full birthday or your address, consider leaving those blank. The less information the company has about you, the less that can end up in cybercriminals’ hands if the app is breached. 

Enjoy Safe Mobile Apps in 2023 

The first step to better cyber habits is arming yourself with the knowledge of the threats that are out there. The best advice here is to slow down, observe and think about your next move every time you download a new app. The signs of a fake are usually not difficult to spot. Then, once you’re confident in its legitimacy, limit the amount of PII you share with it. In this digital world we live in, consider everyone susceptible to a breach. 

To give you peace of mind, supplement your great habits with a tool, like McAfee+ Ultimate, that will cover all your bases and be your partner to live your best private life online.

Researchers Quietly Cracked Zeppelin Ransomware Keys

By BrianKrebs

Peter is an IT manager for a technology manufacturer that got hit with a Russian ransomware strain called “Zeppelin” in May 2020. He’d been on the job less than six months, and because of the way his predecessor architected things, the company’s data backups also were encrypted by Zeppelin. After two weeks of stalling their extortionists, Peter’s bosses were ready to capitulate and pay the ransom demand. Then came the unlikely call from an FBI agent. “Don’t pay,” the agent said. “We’ve found someone who can crack the encryption.”

Peter, who spoke candidly about the attack on condition of anonymity, said the FBI told him to contact a cybersecurity consulting firm in New Jersey called Unit 221B, and specifically its founder — Lance James. Zeppelin sprang onto the crimeware scene in December 2019, but it wasn’t long before James discovered multiple vulnerabilities in the malware’s encryption routines that allowed him to brute-force the decryption keys in a matter of hours, using nearly 100 cloud computer servers.

In an interview with KrebsOnSecurity, James said Unit 221B was wary of advertising its ability to crack Zeppelin ransomware keys because it didn’t want to tip its hand to Zeppelin’s creators, who were likely to modify their file encryption approach if they detected it was somehow being bypassed.

This is not an idle concern. There are multiple examples of ransomware groups doing just that after security researchers crowed about finding vulnerabilities in their ransomware code.

“The minute you announce you’ve got a decryptor for some ransomware, they change up the code,” James said.

But he said the Zeppelin group appears to have stopped spreading their ransomware code gradually over the past year, possibly because Unit 221B’s referrals from the FBI let them quietly help nearly two dozen victim organizations recover without paying their extortionists.

In a blog post published today to coincide with a Black Hat talk on their discoveries, James and co-author Joel Lathrop said they were motivated to crack Zeppelin after the ransomware gang started attacking nonprofit and charity organizations.

“What motivated us the most during the leadup to our action was the targeting of homeless shelters, nonprofits and charity organizations,” the two wrote. “These senseless acts of targeting those who are unable to respond are the motivation for this research, analysis, tools, and blog post. A general Unit 221B rule of thumb around our offices is: Don’t [REDACTED] with the homeless or sick! It will simply trigger our ADHD and we will get into that hyper-focus mode that is good if you’re a good guy, but not so great if you are an ***hole.”

The researchers said their break came when they understood that while Zeppelin used three different types of encryption keys to encrypt files, they could undo the whole scheme by factoring or computing just one of them: An ephemeral RSA-512 public key that is randomly generated on each machine it infects.

“If we can recover the RSA-512 Public Key from the registry, we can crack it and get the 256-bit AES Key that encrypts the files!” they wrote. “The challenge was that they delete the [public key] once the files are fully encrypted. Memory analysis gave us about a 5-minute window after files were encrypted to retrieve this public key.”

Unit 221B ultimately built a “Live CD” version of Linux that victims could run on infected systems to extract that RSA-512 key. From there, they would load the keys into a cluster of 800 CPUs donated by hosting giant Digital Ocean that would then start cracking them. The company also used that same donated infrastructure to help victims decrypt their data using the recovered keys.

A typical Zeppelin ransomware note.

Jon is another grateful Zeppelin ransomware victim who was aided by Unit 221B’s decryption efforts. Like Peter, Jon asked that his last name and that of his employer be omitted from the story, but he’s in charge of IT for a mid-sized managed service provider that got hit with Zeppelin in July 2020.

The attackers that savaged Jon’s company managed to phish credentials and a multi-factor authentication token for some tools the company used to support customers, and in short order they’d seized control over the servers and backups for a healthcare provider customer.

Jon said his company was reluctant to pay a ransom in part because it wasn’t clear from the hackers’ demands whether the ransom amount they demanded would provide a key to unlock all systems, and that it would do so safely.

“They want you to unlock your data with their software, but you can’t trust that,” Jon said. “You want to use your own software or someone else who’s trusted to do it.”

In August 2022, the FBI and the Cybersecurity & Infrastructure Security Agency (CISA) issued a joint warning on Zeppelin, saying the FBI had “observed instances where Zeppelin actors executed their malware multiple times within a victim’s network, resulting in the creation of different IDs or file extensions, for each instance of an attack; this results in the victim needing several unique decryption keys.”

The advisory says Zeppelin has attacked “a range of businesses and critical infrastructure organizations, including defense contractors, educational institutions, manufacturers, technology companies, and especially organizations in the healthcare and medical industries. Zeppelin actors have been known to request ransom payments in Bitcoin, with initial amounts ranging from several thousand dollars to over a million dollars.”

The FBI and CISA say the Zeppelin actors gain access to victim networks by exploiting weak Remote Desktop Protocol (RDP) credentials, exploiting SonicWall firewall vulnerabilities, and phishing campaigns. Prior to deploying Zeppelin ransomware, actors spend one to two weeks mapping or enumerating the victim network to identify data enclaves, including cloud storage and network backups, the alert notes.

Jon said he felt so lucky after connecting with James and hearing about their decryption work, that he toyed with the idea of buying a lottery ticket that day.

“This just doesn’t usually happen,” Jon said. “It’s 100 percent like winning the lottery.”

By the time Jon’s company got around to decrypting their data, they were forced by regulators to prove that no patient data had been exfiltrated from their systems. All told, it took his employer two months to fully recover from the attack.

“I definitely feel like I was ill-prepared for this attack,” Jon said. “One of the things I’ve learned from this is the importance of forming your core team and having those people who know what their roles and responsibilities are ahead of time. Also, trying to vet new vendors you’ve never met before and build trust relationships with them is very difficult to do when you have customers down hard now and they’re waiting on you to help them get back up.”

A more technical writeup on Unit 221B’s discoveries (cheekily titled “0XDEAD ZEPPELIN”) is available here.

What Is Bloatware and How Can It Impact Security?

By McAfee

The joy of purchasing a new device is liberating. Now you can work, learn, and play faster — along with enjoying ample storage space. So, the last thing you’d expect is your apparently safe device being exposed to vulnerabilities, or “bloat.”  

Exposure to unwanted software can derail its performance and hog its storage within a few months of usage. In technical terms, such pieces of software are referred to as bloatware. Bloatware has the potential to attack PCs with Microsoft systems and Android devices. It can also attack Apple iPhones and Macs although their systems tend to be built with a bit more protection.  

This article defines bloatware, offers common examples, explains how to identify it, and discusses its impact on your computer’s security.  

What is bloatware?

Bloatware, also called Junkware or Potentially Unwanted Programs (PUP), are third-party programs that slow down the performance of your device and lay it bare to cybersecurity risks.  

Manufacturers initially introduced bloatware to provide users with more utility, but the programs led to device issues. Software programs that identify as bloatware run in the background, and locating them is not child’s play.  

Bloatware finds its way into your device in two ways: it comes pre-installed or through programs downloaded from the internet. Lenovo‘s Superfish bloatware scandal from 2015 explains how bloatware can harm your devices.  

What are examples of bloatware?

Common examples of bloatware apps include:  

  • Weather checking apps 
  • Finance/money apps 
  • Gaming/sports apps 
  • Map or navigation apps 
  • Fitness/health apps 
  • Messaging or video apps 
  • Music (listening and recording) apps 
  • Toolbars and junk-browser extensions 
  • System update apps 
  • Fake cleaner apps 
  • Productivity assistants 

As a piece of good advice, it is best to uninstall such apps when of no use — whether on your Android smartphone, Windows computer, or an iOS device. 

Signs a program may be bloatware

Performance degradation is a common symptom of a device carrying bloatware. Extended boot-up times, clogged storage, and startup delays are common occurrences. Let’s review some programs that may also be bloatware: 

  • Utilities. This type of bloatware typically shows up as pre-installed software on new devices. Manufacturers and third-party developers create these software programs that offer added functionality to the end-user. Examples include weather tracking apps, music apps, and productivity apps. 
  • Trialware. This is a frequent form of bloatware that comes with new devices for free and works for a set trial period until a license is purchased. In a few cases, trialware is harmless and can be removed easily.  
  • Adware. This is a famous type of software that showcases or downloads advertising material like banners or pop-ups 

Here’s how to identify bloatware: 

  • Anonymous apps installed on your device. Don’t recall installing a specific app on your device? It could be bloatware. Promptly delete apps that are unnecessary.  
  • Bothersome upsells while using an app. Often, the purpose of bloatware is to generate money. It might deploy invasive marketing and sales techniques that can disturb your browsing experience.  
  • Annoying pop-up ads in your browser. If you experience too many pop-up ads redirecting you to unsafe and suspicious websites, that points toward adware. Adware comes from the web and can modify your homepage or tab settings and change the browser setup. 

How can bloatware impact your computer’s security?

As mentioned, not all bloatware is a threat to your device. Some may be useful and can be removed easily. But a major chunk of bloatware is known to slow down your computer.  

Bloatware eats up a good chunk of the disk space or hard drive as it runs in the background, and it drains the battery life. Bloatware that isn’t removed quickly may clog your device with annoying ads. These ads can pose a security threat or even corrupt your operating system 

Can you remove bloatware?

Sadly, it can be a challenge to uninstall bloatware because it finds its way back into the device — sometimes even after it has been deleted. In some cases, it may even redirect you to fake bloatware removal websites and offer malicious removal tools. Such websites ask you to install a new program to remove the previous one, trapping your device further. Unfortunately, there are no secret hacks to stop it from finding a way into your system. 

Pro tip: Anytime you download a program or software, be sure it’s from an official source (like a secured website, the Google Play Store, or the Apple App Store). Installing a program from a suspicious website can put your device at risk, as the program can download bundles of other programs on the back end without your knowledge.  

Windows 10 comes with a special refresh tool to remove any bloatware disguised as user-installed programs. This tool can bring your PC back to a clean slate. It’s important to check your hard drive beforehand, as it can also remove licenses.

Hackers Using Fake CircleCI Notifications to Hack GitHub Accounts

By Ravie Lakshmanan
GitHub has put out an advisory detailing what may be an ongoing phishing campaign targeting its users to steal credentials and two-factor authentication (2FA) codes by impersonating the CircleCI DevOps platform. The Microsoft-owned code hosting service said it learned of the attack on September 16, 2022, adding the campaign impacted "many victim organizations." The fraudulent messages claim to

Deadly Digital Dares: The Blackout Challenge on TikTok

By Toni Birdsong

The social network TikTok is chockfull of interesting, fun, laugh-out-loud videos shared by creators worldwide. Kids, as well as parents, can easily spend hours glued to the platform. But as with most popular platforms, the fun can eventually turn dark, even deadly, when viral challenges make their rounds.  

The latest viral challenge, the “blackout challenge,” first became popular online in 2008 and made its unfortunate comeback in 2021. Before this second round, the CDC attributed nearly 80 deaths to the dangerous online game. In the past month, authorities are attributing the tragic, high-profile deaths of Archie Battersbee, 12, and Leon Brown, 14 to the challenge. 

What is it? 

The blackout challenge is a choking game that involves intentionally trying to choke oneself or another to obtain a brief euphoric state or “high.” Death or serious injury can result if strangulation is prolonged. Those doing the challenge do it privately or broadcast their attempt to friends or followers. The CDC also found that most deaths occurred when a child engaged in the choking game alone and that most parents were unaware of the game before their child’s death.

What’s the appeal? 

It’s easy to look at a challenge like this and dismiss it thinking your child would never be involved in such a dangerous game. However, in a recent post from HealthyChildren.org on why kids participate in online dares, pediatricians point to the reality that the teen brain is still developing. The part of the brain that processes rational thought, the prefrontal cortex, is not fully developed until a person’s mid-20s. This physiological reality means teens are naturally impulsive and can do things without stopping to consider the consequences.  

Another lure that entices teens is that social media’s fast-moving, impulsive environment rewards outrageous behavior—the more outrageous the content, the bigger the bragging rights. The fear of losing out (FOMO is natural for teens. 

Signs to look for 

According to the CDC, signs that a child may be engaging in the blackout challenge include: 

  • They may talk about the game or use alternate terms such as “pass–out
    game” “choking game,” or “space monkey.” 
  • They may have bloodshot eyes 
  • You may see marks on their neck 
  • They might have severe headaches 
  • They could show signs of disorientation after spending time alone 
  • You might notice the presence of ropes, scarves, or belts tied to furniture or doorknobs 
  • They may have unexplained items like dog leashes, choke collars, or bungee cords in their room. 

5 talking points for families

  1. Dig in and discuss hard stuff. Set time aside to talk about the viral challenges your child may or may not notice online. Discuss the dangers, the physiology of being impulsive, and how social network communities inherently reward reckless behavior with likes and shares.  
  2. Make the consequences personal. Do your homework. Pull up the relevant headlines and discuss the implications of the blackout challenge (and others), such as lack of oxygen to the brain, seizures, long-term complications, and death.  
  3. Talk about digital peer pressure. Coach your kids through the dangers they encounter online they may take for granted. Ask them how they feel when they see someone doing dangerous things online and ways to avoid or discourage it. Are your kids rallying around the challenges or sharing the content? Do they try to be funny to get attention online?  
  4. Establish ground rules. As tragic as these challenges are, they allow parents to pause and refresh family ground rules for online behavior and media use. Your kids have changed over time, as have their online communities, and interests. Design ground rules and media use expectations to help shape a safe, balanced digital life that reflects their current online activity. 
  5. Add extra protection. We add security systems to our homes for additional protection from outside threats, so too, it’s wise to add security to our family devices to encourage content filtering, monitoring, and time limits.  

Viral challenges will continue to emerge and shock us. There’s no way to anticipate them or control them. However, staying informed about dangerous online trends and keeping the lines of communication with your child open and honest is a big step toward equipping them to live a safe, balanced digital life.

Kicking Off a New School Year with New Online Habits

By Toni Birdsong

Most every parent loves a new school year. Most likely because the beloved milestone offers us a clean slate and a chance to do things better, shape new habits, and close those digital safety gaps.

The hope that fuels change is a powerful thing. However, if you want to ensure your new habits stick, there’s some science you might consider. Psychologists suggest that to make a new change permanent, you should start with smaller, micro-size choices that will lead to sustainable patterns and habits. Micro habits allow you to take safe steps that are too small to fail but effective enough to generate long-term change. 

Committing to Micro-Habits 

Breaking down the task online safety into bite-sized pieces is a great approach for parents eager to put better habits into play this year. Establishing new ground rules doesn’t have to include restrictions, tantrums, or tears. You can start small, commit to work together, and build your new habits over time. 

So often in this blog we offer a combination of practical digital tips proven to work such as robust password protocols, privacy settings, parental controls, smart phone protection, and social network/app safety.  

Today, however, we will flip that approach and give you some foundations that will no doubt support and amplify your family’s daily online safety efforts. Ready? Here we go! 

5 Foundations of Healthy Family Tech Habits 

1. Put connection first.

We’re all connected 24/7 but to what? Equipping kids to make wise decisions online begins with intentional, face-to-face connection at home with a parent or caregiver. When the parent-child relationship is strong, trust grows, and conversation flows. If and when a challenge arises, your child is more likely to turn to you.  

Micro-habit: If your family doesn’t eat dinner together, start with one night a week (stay consistent with the day). Make the dinner table a no-phone zone and spend that time together listening and connecting. Build from there.  

 

2. Step into their world. 

The new school year is a chance to get more involved with your child’s day-to-day communities (on and offline), including their teachers, friend groups, or hobbies. If you’ve been on the sidelines in the past, taking a few steps into their world can give you an exceptional understanding of their online life. Knowing where they go and who they know online has never been more critical, as outlined in our recent Connected Family Report. 

Micro-habit: Does your child have a favorite app? Download it, look around, and understand the culture.  

3. Prioritize sleep. 

Summer—coupled with extra time online (often unmonitored)—can wreak havoc on a child’s sleep patterns, which, in turn, wreaks havoc on a family. If you have a tween or teen, ensuring they get the required hours of sleep is a significant way to keep them safe online. Think about it. Fatigue can impair judgment, increase anxiety, impact grades, and magnify moodiness, putting a child’s physical and emotional wellbeing at risk online and off.  

Micro-habit: Think about setting a phone curfew that everyone agrees on. Giving your child input into the curfew makes it less of a restriction and more of a health or lifestyle shift. Remember, your child’s device is their lifeline to their peers so cutting them off isn’t a long-term solution.  

4. Monitor mental health. 

With kids spending so much time on apps like TikTok, Instagram, Snapchat, and YouTube, those platforms inevitably influence your child more than just about anyone. Be on the lookout for behavior changes in your child that may be connected to digital risks such as cyberbullying, sextortion, gaming addiction, inappropriate content, or connecting with strangers.

Micro-habit: Consider setting time limits that allow your child to enjoy their online hangouts without being consumed or overly influenced by the wrong voices. Apply limits in small blocks at first and grow from there.  

5. Aim for balance. 

Balancing your online life with face-to-face activities and relationships is a must for your child’s physical and emotional wellbeing. But sometimes, striving for that balance can feel overwhelming. Being too stringent can cause big plans to collapse, sending our behaviors in the opposite direction. Balance requires constant re-calibration and pausing to take those small bites. 

Micro-habit: Commit to one family outdoor activity together a month. Take a hike, learn to fish, take up tennis. Make the outings phone-free zones. Be consistent with your monthly micro-habit and build from there.  

It’s been proven that any change you attempt to make ignites a degree of friction. And prolonged friction can discourage your efforts to stick to new habits. Ignore that noise and keep moving forward. Stay the course parents because this is the year your best intentions take shape.

How 1-Time Passcodes Became a Corporate Liability

By BrianKrebs

Phishers are enjoying remarkable success using text messages to steal remote access credentials and one-time passcodes from employees at some of the world’s largest technology companies and customer support firms. A recent spate of SMS phishing attacks from one cybercriminal group has spawned a flurry of breach disclosures from affected companies, which are all struggling to combat the same lingering security threat: The ability of scammers to interact directly with employees through their mobile devices.

In mid-June 2022, a flood of SMS phishing messages began targeting employees at commercial staffing firms that provide customer support and outsourcing to thousands of companies. The missives asked users to click a link and log in at a phishing page that mimicked their employer’s Okta authentication page. Those who submitted credentials were then prompted to provide the one-time password needed for multi-factor authentication.

The phishers behind this scheme used newly-registered domains that often included the name of the target company, and sent text messages urging employees to click on links to these domains to view information about a pending change in their work schedule.

The phishing sites leveraged a Telegram instant message bot to forward any submitted credentials in real-time, allowing the attackers to use the phished username, password and one-time code to log in as that employee at the real employer website. But because of the way the bot was configured, it was possible for security researchers to capture the information being sent by victims to the public Telegram server.

This data trove was first reported by security researchers at Singapore-based Group-IB, which dubbed the campaign “0ktapus” for the attackers targeting organizations using identity management tools from Okta.com.

“This case is of interest because despite using low-skill methods it was able to compromise a large number of well-known organizations,” Group-IB wrote. “Furthermore, once the attackers compromised an organization they were quickly able to pivot and launch subsequent supply chain attacks, indicating that the attack was planned carefully in advance.”

It’s not clear how many of these phishing text messages were sent out, but the Telegram bot data reviewed by KrebsOnSecurity shows they generated nearly 10,000 replies over approximately two months of sporadic SMS phishing attacks targeting more than a hundred companies.

A great many responses came from those who were apparently wise to the scheme, as evidenced by the hundreds of hostile replies that included profanity or insults aimed at the phishers: The very first reply recorded in the Telegram bot data came from one such employee, who responded with the username “havefuninjail.”

Still, thousands replied with what appear to be legitimate credentials — many of them including one-time codes needed for multi-factor authentication. On July 20, the attackers turned their sights on internet infrastructure giant Cloudflare.com, and the intercepted credentials show at least three employees fell for the scam.

Image: Cloudflare.com

In a blog post earlier this month, Cloudflare said it detected the account takeovers and that no Cloudflare systems were compromised. Cloudflare said it does not rely on one-time passcodes as a second factor, so there was nothing to provide to the attackers. But Cloudflare said it wanted to call attention to the phishing attacks because they would probably work against most other companies.

“This was a sophisticated attack targeting employees and systems in such a way that we believe most organizations would be likely to be breached,” Cloudflare CEO Matthew Prince wrote. “On July 20, 2022, the Cloudflare Security team received reports of employees receiving legitimate-looking text messages pointing to what appeared to be a Cloudflare Okta login page. The messages began at 2022-07-20 22:50 UTC. Over the course of less than 1 minute, at least 76 employees received text messages on their personal and work phones. Some messages were also sent to the employees family members.”

On three separate occasions, the phishers targeted employees at Twilio.com, a San Francisco based company that provides services for making and receiving text messages and phone calls. It’s unclear how many Twilio employees received the SMS phishes, but the data suggest at least four Twilio employees responded to a spate of SMS phishing attempts on July 27, Aug. 2, and Aug. 7.

On that last date, Twilio disclosed that on Aug. 4 it became aware of unauthorized access to information related to a limited number of Twilio customer accounts through a sophisticated social engineering attack designed to steal employee credentials.

“This broad based attack against our employee base succeeded in fooling some employees into providing their credentials,” Twilio said. “The attackers then used the stolen credentials to gain access to some of our internal systems, where they were able to access certain customer data.”

That “certain customer data” included information on roughly 1,900 users of the secure messaging app Signal, which relied on Twilio to provide phone number verification services. In its disclosure on the incident, Signal said that with their access to Twilio’s internal tools the attackers were able to re-register those users’ phone numbers to another device.

On Aug. 25, food delivery service DoorDash disclosed that a “sophisticated phishing attack” on a third-party vendor allowed attackers to gain access to some of DoorDash’s internal company tools. DoorDash said intruders stole information on a “small percentage” of users that have since been notified. TechCrunch reported last week that the incident was linked to the same phishing campaign that targeted Twilio.

This phishing gang apparently had great success targeting employees of all the major mobile wireless providers, but most especially T-Mobile. Between July 10 and July 16, dozens of T-Mobile employees fell for the phishing messages and provided their remote access credentials.

“Credential theft continues to be an ongoing issue in our industry as wireless providers are constantly battling bad actors that are focused on finding new ways to pursue illegal activities like this,” T-Mobile said in a statement. “Our tools and teams worked as designed to quickly identify and respond to this large-scale smishing attack earlier this year that targeted many companies. We continue to work to prevent these types of attacks and will continue to evolve and improve our approach.”

This same group saw hundreds of responses from employees at some of the largest customer support and staffing firms, including Teleperformanceusa.com, Sitel.com and Sykes.com. Teleperformance did not respond to requests for comment. KrebsOnSecurity did hear from Christopher Knauer, global chief security officer at Sitel Group, the customer support giant that recently acquired Sykes. Knauer said the attacks leveraged newly-registered domains and asked employees to approve upcoming changes to their work schedules.

Image: Group-IB.

Knauer said the attackers set up the phishing domains just minutes in advance of spamming links to those domains in phony SMS alerts to targeted employees. He said such tactics largely sidestep automated alerts generated by companies that monitor brand names for signs of new phishing domains being registered.

“They were using the domains as soon as they became available,” Knauer said. “The alerting services don’t often let you know until 24 hours after a domain has been registered.”

On July 28 and again on Aug. 7, several employees at email delivery firm Mailchimp provided their remote access credentials to this phishing group. According to an Aug. 12 blog post, the attackers used their access to Mailchimp employee accounts to steal data from 214 customers involved in cryptocurrency and finance.

On Aug. 15, the hosting company DigitalOcean published a blog post saying it had severed ties with MailChimp after its Mailchimp account was compromised. DigitalOcean said the MailChimp incident resulted in a “very small number” of DigitalOcean customers experiencing attempted compromises of their accounts through password resets.

According to interviews with multiple companies hit by the group, the attackers are mostly interested in stealing access to cryptocurrency, and to companies that manage communications with people interested in cryptocurrency investing. In an Aug. 3 blog post from email and SMS marketing firm Klaviyo.com, the company’s CEO recounted how the phishers gained access to the company’s internal tools, and used that to download information on 38 crypto-related accounts.

The ubiquity of mobile phones became a lifeline for many companies trying to manage their remote employees throughout the Coronavirus pandemic. But these same mobile devices are fast becoming a liability for organizations that use them for phishable forms of multi-factor authentication, such as one-time codes generated by a mobile app or delivered via SMS.

Because as we can see from the success of this phishing group, this type of data extraction is now being massively automated, and employee authentication compromises can quickly lead to security and privacy risks for the employer’s partners or for anyone in their supply chain.

Unfortunately, a great many companies still rely on SMS for employee multi-factor authentication. According to a report this year from Okta, 47 percent of workforce customers deploy SMS and voice factors for multi-factor authentication. That’s down from 53 percent that did so in 2018, Okta found.

Some companies (like Knauer’s Sitel) have taken to requiring that all remote access to internal networks be managed through work-issued laptops and/or mobile devices, which are loaded with custom profiles that can’t be accessed through other devices.

Others are moving away from SMS and one-time code apps and toward requiring employees to use physical FIDO multi-factor authentication devices such as security keys, which can neutralize phishing attacks because any stolen credentials can’t be used unless the phishers also have physical access to the user’s security key or mobile device.

This came in handy for Twitter, which announced last year that it was moving all of its employees to using security keys, and/or biometric authentication via their mobile device. The phishers’ Telegram bot reported that on June 16, 2022, five employees at Twitter gave away their work credentials. In response to questions from KrebsOnSecurity, Twitter confirmed several employees were relieved of their employee usernames and passwords, but that its security key requirement prevented the phishers from abusing that information.

Twitter accelerated its plans to improve employee authentication following the July 2020 security incident, wherein several employees were phished and relieved of credentials for Twitter’s internal tools. In that intrusion, the attackers used Twitter’s tools to hijack accounts for some of the world’s most recognizable public figures, executives and celebrities — forcing those accounts to tweet out links to bitcoin scams.

“Security keys can differentiate legitimate sites from malicious ones and block phishing attempts that SMS 2FA or one-time password (OTP) verification codes would not,” Twitter said in an Oct. 2021 post about the change. “To deploy security keys internally at Twitter, we migrated from a variety of phishable 2FA methods to using security keys as our only supported 2FA method on internal systems.”

Update, 6:02 p.m. ET: Clarified that Cloudflare does not rely on TOTP (one-time multi-factor authentication codes) as a second factor for employee authentication.

GitLab Issues Patch for Critical Flaw in its Community and Enterprise Software

By Ravie Lakshmanan
DevOps platform GitLab this week issued patches to address a critical security flaw in its software that could lead to arbitrary code execution on affected systems. Tracked as CVE-2022-2884, the issue is rated 9.9 on the CVSS vulnerability scoring system and impacts all versions of GitLab Community Edition (CE) and Enterprise Edition (EE) starting from 11.3.4 before 15.1.5, 15.2 before 15.2.3,

Sounding the Alarm on Emergency Alert System Flaws

By BrianKrebs

The Department of Homeland Security (DHS) is urging states and localities to beef up security around proprietary devices that connect to the Emergency Alert System — a national public warning system used to deliver important emergency information, such as severe weather and AMBER alerts. The DHS warning came in advance of a workshop to be held this weekend at the DEFCON security conference in Las Vegas, where a security researcher is slated to demonstrate multiple weaknesses in the nationwide alert system.

A Digital Alert Systems EAS encoder/decoder that Pyle said he acquired off eBay in 2019. It had the username and password for the system printed on the machine.

The DHS warning was prompted by security researcher Ken Pyle, a partner at security firm Cybir. Pyle said he started acquiring old EAS equipment off of eBay in 2019, and that he quickly identified a number of serious security vulnerabilities in a device that is broadly used by states and localities to encode and decode EAS alert signals.

“I found all kinds of problems back then, and reported it to the DHS, FBI and the manufacturer,” Pyle said in an interview with KrebsOnSecurity. “But nothing ever happened. I decided I wasn’t going to tell anyone about it yet because I wanted to give people time to fix it.”

Pyle said he took up the research again in earnest after an angry mob stormed the U.S. Capitol on Jan. 6, 2021.

“I was sitting there thinking, ‘Holy shit, someone could start a civil war with this thing,”’ Pyle recalled. “I went back to see if this was still a problem, and it turns out it’s still a very big problem. So I decided that unless someone actually makes this public and talks about it, clearly nothing is going to be done about it.”

The EAS encoder/decoder devices Pyle acquired were made by Lyndonville, NY-based Digital Alert Systems (formerly Monroe Electronics, Inc.), which issued a security advisory this month saying it released patches in 2019 to fix the flaws reported by Pyle, but that some customers are still running outdated versions of the device’s firmware. That may be because the patches were included in version 4 of the firmware for the EAS devices, and many older models apparently do not support the new software.

“The vulnerabilities identified present a potentially serious risk, and we believe both were addressed in software updates issued beginning Oct 2019,” EAS said in a written statement. “We also provided attribution for the researcher’s responsible disclosure, allowing us to rectify the matters before making any public statements. We are aware that some users have not taken corrective actions and updated their software and should immediately take action to update the latest software version to ensure they are not at risk. Anything lower than version 4.1 should be updated immediately. On July 20, 2022, the researcher referred to other potential issues, and we trust the researcher will provide more detail. We will evaluate and work to issue any necessary mitigations as quickly as possible.”

But Pyle said a great many EAS stakeholders are still ignoring basic advice from the manufacturer, such as changing default passwords and placing the devices behind a firewall, not directly exposing them to the Internet, and restricting access only to trusted hosts and networks.

Pyle, in a selfie that is heavily redacted because the EAS device behind him had its user credentials printed on the lid.

Pyle said the biggest threat to the security of the EAS is that an attacker would only need to compromise a single EAS station to send out alerts locally that can be picked up by other EAS systems and retransmitted across the nation.

“The process for alerts is automated in most cases, hence, obtaining access to a device will allow you to pivot around,” he said. “There’s no centralized control of the EAS because these devices are designed such that someone locally can issue an alert, but there’s no central control over whether I am the one person who can send or whatever. If you are a local operator, you can send out nationwide alerts. That’s how easy it is to do this.”

One of the Digital Alert Systems devices Pyle sourced from an electronics recycler earlier this year was non-functioning, but whoever discarded it neglected to wipe the hard drive embedded in the machine. Pyle soon discovered the device contained the private cryptographic keys and other credentials needed to send alerts through Comcast, the nation’s third-largest cable company.

“I can issue and create my own alert here, which has all the valid checks or whatever for being a real alert station,” Pyle said in an interview earlier this month. “I can create a message that will start propagating through the EAS.”

Comcast told KrebsOnSecurity that “a third-party device used to deliver EAS alerts was lost in transit by a trusted shipping provider between two Comcast locations and subsequently obtained by a cybersecurity researcher.

“We’ve conducted a thorough investigation of this matter and have determined that no customer data, and no sensitive Comcast data, were compromised,” Comcast spokesperson David McGuire said.

The company said it also confirmed that the information included on the device can no longer be used to send false messages to Comcast customers or used to compromise devices within Comcast’s network, including EAS devices.

“We are taking steps to further ensure secure transfer of such devices going forward,” McGuire said. “Separately, we have conducted a thorough audit of all EAS devices on our network and confirmed that they are updated with currently available patches and are therefore not vulnerable to recently reported security issues. We’re grateful for the responsible disclosure and to the security research community for continuing to engage and share information with our teams to make our products and technologies ever more secure. Mr. Pyle informed us promptly of his research and worked with us as we took steps to validate his findings and ensure the security of our systems.”

The user interface for an EAS device.

Unauthorized EAS broadcast alerts have happened enough that there is a chronicle of EAS compromises over at fandom.com. Thankfully, most of these incidents have involved fairly obvious hoaxes.

According to the EAS wiki, in February 2013, hackers broke into the EAS networks in Great Falls, Mt. and Marquette, Mich. to broadcast an alert that zombies had risen from their graves in several counties. In Feb. 2017, an EAS station in Indiana also was hacked, with the intruders playing the same “zombies and dead bodies” audio from the 2013 incidents.

“On February 20 and February 21, 2020, Wave Broadband’s EASyCAP equipment was hacked due to the equipment’s default password not being changed,” the Wiki states. “Four alerts were broadcasted, two of which consisted of a Radiological Hazard Warning and a Required Monthly Test playing parts of the Hip Hop song Hot by artist Young Thug.”

In January 2018, Hawaii sent out an alert to cell phones, televisions and radios, warning everyone in the state that a missile was headed their way. It took 38 minutes for Hawaii to let people know the alert was a misfire, and that a draft alert was inadvertently sent. The news video clip below about the 2018 event in Hawaii does a good job of walking through how the EAS works.

Hackers Behind Twilio Breach Also Targeted Cloudflare Employees

By Ravie Lakshmanan
Web infrastructure company Cloudflare on Tuesday disclosed at least 76 employees and their family members received text messages on their personal and work phones bearing similar characteristics as that of the sophisticated phishing attack against Twilio.

5 Steps to Removing Your Personal Information From the Internet

By McAfee

Here’s one way you can help reduce your chances of identity theft: remove your personal information from the internet. 

And chances are, you have more personal information posted online than you think. 

According to the U.S. Federal Trade Commission (FTC), consumers registered 1.4 million identity theft complaints in 2021, all part of a year where consumers reported losing $5.8 billion to fraud overall—a 70% increase over the year prior.  

What fuels all this theft and fraud? Access to personal information.  

Scammers and thieves can get a hold of personal information in several ways, such as through phishing attacks that lure you into handing it over, malware that steals it from your devices, by purchasing your information on dark web marketplaces, or as a result of information leaked in data breaches, just to name a few. 

However, scammers and thieves have other resources to help them commit theft and fraud—data broker sites, places where personal information is posted online for practically anyone to see. Which makes removing your info from them so important, from both an identity and privacy standpoint. 

What are data broker sites? 

Think of data broker sites as huge repositories of personal information. Search your name and address online and you’ll see. You’ll likely find dozens of sites that turn up information about you, some of which offer a few pieces for free and others that offer far more information for a price. 

Data brokers collect and then aggregate personal information from several sources, including: 

  • Your public records posted online. 
  • Information from social media accounts you keep public. 
  • The websites you visit and the smartphone apps you use. 
  • Along with retailers, who share information associated with your loyalty cards. 

Data brokers also buy personal information from other data brokers. As a result, some data brokers have thousands of pieces of data for billions of individuals worldwide 

What could that look like? A broker may know how much you paid for your home, your education level, where you’ve lived over the years and who your lived with, your driving record, and possibly your political leanings. A broker may also know your favorite flavor of ice cream and your preferred over-the-counter allergy medicine thanks to information from loyalty cards. Further, they may also have health-related information from fitness apps. The amount of personal information can run that broadly, and that deeply. 

With information at this potential level of detail, it’s no wonder that data brokers rake in an estimated at $200 billion U.S. dollars worldwide every year. 

Who uses the personal information found on data broker sites?  

On the legitimate side, it’s used by advertisers to create targeted ad campaigns. With information sold by data brokers, they can generate lists based on highly specific criteria, such as shopping histories, personal interests, and even political leanings as mentioned above. Likely without you being aware of it—and likely with no way to contest that information if it’s incorrect. 

Other legitimate uses include using these sites for background checks. Law enforcement, reporters, and employers will use data brokers as a starting point for research because the leg work has largely been done for them. Namely, data brokers have aggregated a person’s information already, which is an otherwise time-consuming process. 

If this seems a little shady, it’s still legal. As of now, the U.S. has no federal laws that regulate data brokers or require data them to remove personal information if requested. A few states, such as Nevada, Vermont, and California, have legislation in place aimed at protecting consumers. Meanwhile, the General Data Protection Regulation (GDPR) in the European Union has stricter rules about what information can be collected and what can be done with it. Still, the data broker economy thrives. 

On the darker side, scammers and thieves use personal information for identity theft and fraud. With enough personal information gathered from enough sources, they can create a high-fidelity profile of their victims. One that gives them enough information to open new accounts in their name. 

So, from the standpoint of both privacy and identity, cleaning up your personal information online makes a great deal of sense.  

How to remove your personal information from the internet 

Let’s review some ways you can remove your personal information from data brokers and other sources on the internet.  

1. Request to remove data from data broker sites 

The process starts with finding the sites that have your information. From there, you can request to have it removed. Yet as mentioned above, there are dozens and dozens of these sites. Knowing where to start is a challenge in of itself, as is manually making the requests once you have identified the sites that post and sell information about you.  

Our Personal Data Cleanup can do the work for you. Personal Data Cleanup scans some of the riskiest data broker sites and shows you which ones are selling your personal info. It also provides guidance on how you can remove your data from those sites and can even manage the removal for you depending on your plan. ​It also monitors those sites, so if your info gets posted again, you can request its removal again. 

2. Limit the data Google collects 

As of September 2022, Google accounts for just over 92% of search engine market share worldwide. Aside from being a search engine, Google offers a myriad of other services and applications, such as Gmail and Google Maps. While Google offers plenty of tools for productivity, travel, work, and play for free, they still come at a cost—the gathering and analysis of your personal information.   

You can limit the data Google associates with you by removing your name from Google search results with a removal request. This will disable anyone online from getting any results if they search your name. (Note that this will not remove your information from the original sites and sources where it’s posted.) Moreover, Google collects all your browsing data continuously. You have the option to turn on “Auto Delete” in your privacy settings to ensure that the data is deleted regularly and help limit the amount of time your sensitive data stays vulnerable.  

You can also occasionally delete your cookies or use your browser in incognito mode to prevent websites from being tracked back to you. Go to your Google Chrome settings to clear your browser and cookie history.  

3. Delete old social media accounts and make the ones you keep private 

As discussed above, data brokers can collect information from public social media profiles. You can minimize your presence on social media to the bare minimum. Make a list of the ones you use or have used in the past. If there are old accounts that you no longer use or websites that have gone by the wayside like Myspace or Tumblr, you may want to deactivate them or consider deleting them entirely.   

For social media platforms that you still may use regularly, like Facebook and Instagram, consider adjusting your privacy settings to ensure that your personal information on these social media platforms is the bare minimum. For example, on Facebook you can lock your profile, while on Instagram you can stay private.  

4. Remove personal info from other websites and blogs 

If you’ve ever published articles, written blogs, or created any content online, it might be a good time to consider taking it down if it is no longer serving a purpose. Depending on what you’ve posted, you may have shared personal details about your life. Additionally, you might be mentioned by other people in various social media posts, articles, or blogs. It is worth reaching out to these people to request them to take down posts with sensitive information.  

Social media and online articles that host your personal information are often used when businesses or hackers are doing “internet scrapes” to find better ways to use your targeted information. Asking your friends or third-party sites to remove that information can help protect your privacy.  

5. Delete unused phone apps and restrict the settings for the ones you use 

Another way you can tidy up your digital footprint online involves deleting all the unnecessary phone apps that you no longer need or use. Even when apps are not open or in use, they may be able to track personal information such as your real-time location and even your payment details if you have a paid subscription to the app.   

Some apps even sell this data as it can be extremely advantageous to other companies, which they use to target certain consumer segments and profiles for advertising. Try to share as little information with apps as possible if you’re looking to minimize your online footprint, and provide them access to your photos, contacts, and location only on as-needed basis and only when the app is in use. Your phone’s app and location services settings will give you the tools to do it. 

Online protection software can keep your personal information more private and secure 

In addition to the steps above, comprehensive online protection software can keep you more private and minimize your risk of cybercrime. It can include: 

So while it may seem like all this rampant collecting and selling of personal information is out of your hands, there’s plenty you can do to take control. With the steps outlined above and strong online protection software at your back, you can keep your personal information more private and secure.

Top of Mind Security Insights from In-Person Interactions

By Shailaja Shankar

The past few months have been chockfull of conversations with security customers, partners, and industry leaders. After two years of virtual engagements, in-person events like our CISO Forum and Cisco Live as well as the industry’s RSA Conference underscore the power of face-to-face interactions. It’s a reminder of just how enriching conversations are and how incredibly interconnected the world is. And it’s only made closer by the security experiences that impact us all.  

I had the pleasure of engaging with some of the industry’s best and brightest, sharing ideas, insights, and what keeps us up at night. The conversations offered more than an opportunity to reconnect and put faces with names. It was a chance to discuss some of the most critical cybersecurity issues and implications that are top of mind for organizations.  

The collective sentiments are clear. The need for better security has never been so strong. Securing the future is good business. Disruptions are happening faster than ever before, making our interconnected world more unpredictable.  Hybrid work is here to stay, hybrid and complex architectures will continue to be a reality for most organizations and that has dramatically expanded the threat surface. More and more businesses are operating as ecosystems—attacks have profound ripple effects across value chains. Attacks are becoming more bespoke, government-sponsored threat actors and ransomware as a service, continue to unravel challenging businesses to minimize the time from initial breach to complete compromise, in the event of a compromise.  

Digital transformation and Zero Trust 

Regardless of where organizations are on their digital transformations, they are progressively embarking upon journeys to unify networking and secure connectivity needs. Mobility, BYOD (bring your own device), cloud, increased collaboration, and the consumerization of IT have necessitated a new type of access control security–zero trust security. Supporting a modern enterprise across a distributed network and infrastructure involves the ability to validate user IDs, continuously verify authentication and device trust, and protect every application— 

without compromising user experience. Zero trust offers organizations a simpler approach to securing access for everyone, from any device, anywhere—all the while, making it harder for attackers.  

Seeking a simpler, smarter ecosystem 

Simplicity continues to be a hot topic, and in the context of its functionality. In addition to a frictionless user experience, the real value to customers is improving operational challenges. Security practitioners want an easier way to secure the edge, access, and operations—including threat intelligence and response. Key to this simplified experience is connecting and managing business-critical control points and vulnerabilities, exchanging data, and contextualizing threat intelligence. And it requires a smarter ecosystem that brings together capabilities, unifying admin, policy, visibility, and control. Simplicity that works hard and smart—and enhances their security posture. The ultimate simplicity is improved efficacy for the organization. 

Everyone is an insider  

Insider cyber-attacks are among the fastest growing threats in the modern security network, an increasingly common cause of data breaches. Using their authorized access, employees are intentionally or inadvertently causing harm by stealing, exposing, or destroying sensitive company data. Regardless, the consequences are the same—costing companies big bucks and massive disruption. It’s also one of the reasons why “identity as the new perimeter” is trending, as the primary objective of all advanced attacks is to gain privileged credentials. Insider attack attempts are not slowing down. However, advanced telemetry, threat detection and protection, and continuous trusted access all help decelerate the trend. Organizations are better able to expose suspicious or malicious activities caused by insider threats. Innovations are enabling business to analyze all network traffic and historical patterns of employee access and determine whether to let an employee continue uninterrupted or prompt to authenticate again.  

The interconnection conundrum and the ransomware ruse   

Supply chain attacks have become one of the biggest security worries for businesses. Not only are disruptions debilitating, but no one knew the impacts or perceived outcomes. Attackers are highly aware that supply chains are comprised of larger entities often tightly connected to a broad array of smaller and less cyber-savvy organizations. Lured by lucrative payouts, attackers seek the weakest supply chain link for a successful breach. In fact, two of the four biggest cyber-attacks that the Cisco Talos team saw in the field last year were supply chain attacks that deployed ransomware on their targets’ networks: SolarWinds and REvil’s attack exploiting the Kaseya managed service provider. While there’s no perfect way to absolutely protect from ransomware, businesses are taking steps to bolster their defenses and protect against disaster. 

Data privacy is getting personal 

Security incidents targeting personal information are on the rise. In fact, 86 percent of global consumers were victims of identity theft, credit/debit card fraud, or a data breach in 2020. In a recent engagement discovered by the Cisco Talos team, the API on a customer’s website could have been exploited by an attacker to steal sensitive personal information. The good news is governments and businesses alike are leaning into Data Privacy and Protection, adhering to global regulations​ that enforce high standards for collecting, using, disclosing, storing, securing, accessing, transferring, and processing personal data.​ Within the past year, the U.S. government implemented new rules to ensure companies and federal agencies follow required cybersecurity standards. As long as cyber criminals continue seeking to breach our privacy and data, these rules help hold us accountable.  

Through all the insightful discussions with customers, partners, and industry leaders, a theme emerged. When it comes to cybersecurity, preparation is key and the cost of being wrong is extraordinary. By acknowledging there will continue to be disruptions, business can prepare for whatever comes next. And when it comes, they’ll not only weather the storm, but they will also come out of it stronger. And the good news is that Cisco Security Business Group is already on the journey actively addressing these headlines, and empowering our customers to reach their full potential, securely.
