FBI warns of time-traveling hackers

Cybercriminals always find new ways to scam you, whether it’s mimicking a government agency, creating a fake website or delivering malware disguised as a software update. Just when you think you’ve seen it all, they come up with a new trick.

This time, the FBI has issued an alert: Hackers are using a “time-traveling” technique to bypass your device’s security measures. No, we’re not talking about actual time travel (though wouldn’t that be something?). This is a sophisticated cyberattack where hackers manipulate a system’s internal clock to sneak past security defenses.

What you need to know

The concept of “time-traveling hackers” refers not to literal time travel but to a sophisticated cyberattack technique where hackers manipulate a system’s internal clock to bypass security measures. This attack is reportedly tied to the Medusa ransomware gang.

In this type of attack, hackers exploit expired security certificates by altering the system date on a targeted device to a time when those certificates were still valid. For example, a security certificate that expired in, say, 2020 could be made usable again if the system’s clock is set back to 2019. This allows malicious software signed with these outdated certificates to be recognized as legitimate by the system, effectively “traveling back in time” from a security perspective. 

This technique was notably used in the Medusa ransomware attacks, which targeted critical infrastructure and prompted an FBI cybersecurity advisory (AA25-071A) earlier in 2025. The campaign has affected over 300 critical infrastructure targets. The attackers combined this method with social engineering and exploited unpatched vulnerabilities, amplifying the threat. 

The FBI has warned that such attacks pose a significant risk, as they can disable modern security protections like Windows Defender by tricking the system into accepting outdated drivers or software.

What does the FBI recommend?

Traditional search and rescue tools, like rigid robots and specialized cameras, often struggle in disaster zones. Cameras follow only straight paths, forcing teams to cut through debris just to see further in. Rigid robots are vulnerable in tight, unstable spaces and expensive to repair when damaged. And manual probing is slow, exhausting and risks responder safety.

5 ways to stay safe from Medusa malware

1) Use strong antivirus software: A strong antivirus isn’t just for catching old-school viruses anymore. It can detect phishing links, block malicious downloads and stop ransomware before it gets a foothold. Since the Medusa gang uses fake updates and social engineering to trick users, having strong antivirus software adds a critical layer of protection against threats you might not see coming. Get my picks of the best 2025 antivirus protection winners for your Windows, Mac, Android and iOS devices.

2) Enable two-factor authentication (2FA): The FBI specifically recommends enabling 2FA across all services, especially for high-value targets like webmail accounts, VPNs and remote access tools. 2FA makes it significantly harder for attackers to break in, even if they’ve managed to steal your username and password through phishing or other tactics.

3) Use strong, unique passwords: Many ransomware groups, including Medusa, rely on reused or weak passwords to gain access. Using a strong password (think long, random and unique to each account) greatly reduces that risk. A password manager can help you generate and store complex passwords so you don’t have to remember them all yourself. Get more details about my best expert-reviewed password managers of 2025 here.

4) Monitor for suspicious system time changes: The core of this “time-traveling” attack is clock manipulation: Hackers roll back a device’s clock to a time when expired security certificates were still valid. This allows outdated and potentially malicious software to appear trustworthy. Be alert to unexpected system time changes, and if you’re managing an organization, use tools that flag and log these types of configuration shifts.

5) Keep systems updated and patch known vulnerabilities: The Medusa ransomware campaign has a track record of exploiting unpatched systems. That means old software, outdated drivers and ignored security updates can all become entry points. Regularly installing updates for your OS, applications and drivers is one of the most effective ways to stay protected. Don’t put off those system notifications; they exist for a reason.

Kurt’s key takeaway

The Medusa attack is a good example of how cybercriminals are shifting tactics. Instead of relying on traditional methods like brute force or obvious exploits, they are targeting the basic logic that systems depend on to function. In this case, it is something as simple as the system clock. This kind of strategy challenges the way we think about security. It is not just about building stronger defenses but also about questioning the default assumptions built into the technology we use every day.

What Trump’s ‘ratepayer protection pledge’ means for you

What Trump’s ‘ratepayer protection pledge’ means for you

NEWYou can now listen to Fox News articles!

When you open a chatbot, stream a show or back up photos to the cloud, you are tapping into a vast network of data centers. These facilities power artificial intelligence, search engines and online services we use every day. Now there is a growing debate over who should pay for the electricity those data centers consume.

During President Trump’s State of the Union address this week, he introduced a new initiative called the “ratepayer protection pledge” to shift AI-driven electricity costs away from consumers. The core idea is simple. 

Tech companies that run energy-intensive AI data centers should cover the cost of the extra electricity they require rather than passing those costs on to everyday customers through higher utility rates.

It sounds simple. The hard part is what happens next.

Why AI is driving a surge in electricity demand

AI systems require enormous computing power. That computing power requires enormous electricity. Today’s data centers can consume as much power as a small city. As AI tools expand across business, healthcare, finance and consumer apps, energy demand has risen sharply in certain regions.

Utilities have warned that the current grid in many parts of the country was not built for this level of concentrated demand. Upgrading substations, transmission lines and generation capacity costs money. Traditionally, those costs can influence rates paid by homes and small businesses. That is where the pledge comes in.

What the ratepayer protection pledge is designed to do

Under the ratepayer protection pledge, large technology companies would:

Advertisement
  • Cover the full cost of additional electricity tied to their data centers
  • Build their own on-site power generation to reduce strain on the public grid

Supporters say this approach separates residential energy costs from large-scale AI expansion. In other words, your household bill should not rise simply because a new AI data center opens nearby. So far, Anthropic is the clearest public backer. CyberGuy reached out to Anthropic for a comment on its role in the pledge. A company spokesperson referred us to a tweet from Anthropic Head of External Affairs Sarah Heck.

“American families shouldn’t pick up the tab for AI,” Heck wrote in a post on X. “In support of the White House ratepayer protection pledge, Anthropic has committed to covering 100% of electricity price increases that consumers face from our data centers.”

That makes Anthropic one of the first major AI companies to publicly state it will absorb consumer electricity price increases tied to its data center operations. Other major firms may be close behind. The White House reportedly plans to host Microsoft, Meta and Anthropic in early March to discuss formalizing a broader deal, though attendance and final terms have not been confirmed publicly.

Microsoft also expressed support for the initiative. 

“The ratepayer protection pledge is an important step,” Brad Smith, Microsoft vice chair and president, said in a statement to CyberGuy. “We appreciate the administration’s work to ensure that data centers don’t contribute to higher electricity prices for consumers.”  

Industry groups also point to companies such as Google and utilities including Duke Energy and Georgia Power as making consumer-focused commitments tied to data center growth. However, enforcement mechanisms and long-term regulatory details remain unclear.

How this could change the economics of AI

AI infrastructure is already one of the most expensive technology buildouts in history. Companies are investing billions in chips, servers and real estate. If firms must also finance dedicated power plants or pay premium rates for grid upgrades, the cost of running AI systems increases further. That could lead to:

  • Slower expansion in some markets
  • Greater investment in renewable energy and storage
  • More partnerships between tech firms and utilities

Energy strategy may become just as important as computing strategy. For consumers, this shift signals that electricity is now a central part of the AI conversation. AI is no longer only about software. It is also about infrastructure.

The bigger consumer tech picture

AI is becoming embedded in smartphones, search engines, office software and home devices. As adoption grows, so does the hidden infrastructure supporting it. Energy is now part of the conversation around everyday technology. Every AI-generated image, voice command or cloud backup depends on a power-hungry network of servers.

By asking companies to account more directly for their electricity use, policymakers are acknowledging a new reality. The digital world runs on very physical resources. For you, that shift could mean more transparency. It also raises new questions about sustainability, local impact and long-term costs.

What this means for you

If you are a homeowner or renter, the practical question is simple. Will this protect my electric bill? In theory, separating data center energy costs from residential rates could reduce the risk of price spikes tied to AI growth. If companies fund their own generation or grid upgrades, utilities may have less reason to spread those costs among all customers.

That said, utility pricing is complex. It depends on state regulators, long-term planning and local energy markets.

Here is what you can watch for in your area:

Advertisement
  • New data center construction announcements
  • Utility filings that mention large commercial load growth
  • Public service commission decisions on rate adjustments

Even if you rarely use AI tools, your community could feel the effects of a nearby data center. The pledge is intended to keep those large-scale power demands from showing up in your monthly bill.

Kurt’s key takeaways

The ratepayer protection pledge highlights an important turning point. AI is no longer only about innovation and speed. It is also about energy and accountability. If tech companies truly absorb the cost of their expanding power needs, households may avoid some of the financial strain tied to rapid AI growth. If not, utility bills could become an unexpected front line in the AI era.

Here’s your first look at Kratos in Amazon’s God of War show

Amazon has slowly been teasing out casting details for its live-action adaptation of God of War, and now we have our first look at the show. It’s a single image but a notable one showing protagonist Kratos and his son Atreus. The characters are played by Ryan Hurst and Callum Vinson, respectively, and they look relatively close to their video game counterparts.

There aren’t a lot of other details about the show just yet, but this is Amazon’s official description:

The God of War series storyline follows father and son Kratos and Atreus as they embark on a journey to spread the ashes of their wife and mother, Faye. Through their adventures, Kratos tries to teach his son to be a better god, while Atreus tries to teach his father how to be a better human.

That sounds a lot like the recent soft reboot of the franchise, which started with 2018’s God of War and continued through Ragnarök in 2022. For the Amazon series, Ronald D. Moore, best-known for his work on For All Mankind and Battlestar Galactica, will serve as showrunner. The rest of the cast includes: Mandy Patinkin (Odin), Ed Skrein (Baldur), Max Parker (Heimdall), Ólafur Darri Ólafsson (Thor), Teresa Palmer (Sif), Alastair Duncan (Mimir), Jeff Gulka (Sindri), and Danny Woodburn (Brok).

While production is underway on the God of War series, there’s no word on when it might start streaming.

300,000 Chrome users hit by fake AI extensions

NEWYou can now listen to Fox News articles!

Your web browser may feel like a safe place, especially when you install helpful tools that promise to make your life easier. But security researchers have uncovered a dangerous campaign in which more than 300,000 people installed Chrome extensions pretending to be artificial intelligence (AI) assistants. Instead of helping, these fake tools secretly collect sensitive information like your emails, passwords and browsing activity.

They used familiar names like ChatGPT, Gemini and AI Assistant. If you use Chrome and have installed any AI-related extension, your personal information may already be exposed. Even worse, some of these malicious extensions are still available today, putting more people at risk without their knowing.

What you need to know about fake AI extensions

Security researchers at browser security company LayerX discovered a large campaign involving 30 malicious Chrome extensions disguised as AI-powered assistants (via BleepingComputer). Together, these extensions were installed more than 300,000 times by unsuspecting users.

Some of the most popular extensions included names like AI Sidebar with 70,000 users, AI Assistant with 60,000 users, ChatGPT Translate with 30,000 users, and Google Gemini with 10,000 users. Another extension called Gemini AI Sidebar had 80,000 users before it was removed.

These extensions were distributed through the official Chrome Web Store, which made them appear legitimate and trustworthy. Even more concerning, researchers found that many of these extensions were connected to the same malicious server, showing they were part of a coordinated effort.

While some extensions have since been removed, others remain available. This means new users could still unknowingly install them and expose their personal data. Here’s the list of the affected extensions:

  • AI Assistant
  • Llama
  • Gemini AI Sidebar
  • AI Sidebar
  • ChatGPT Sidebar

How the fake AI Chrome extension attack works

These fake extensions pretend to offer helpful AI features, such as translating text, summarizing emails, or acting as an AI assistant. But behind the scenes, they quietly monitor what you are doing online.

Once installed, the extension gains permission to view and interact with the websites you visit. This allows it to read the contents of web pages, including login screens where you enter your username and password.

In some cases, the extensions specifically targeted Gmail. They could read your email messages directly from your browser, including emails you received and even drafts you were still writing. This means attackers could access private conversations, financial information and sensitive personal details.

The extensions then sent this information to servers controlled by the attackers. Because they loaded content remotely, the attackers could change their behavior at any time without needing to update the extension.

Some versions could also activate voice features through your browser. This could potentially capture spoken conversations near your device and send transcripts back to the attackers.

If you installed one of these extensions, attackers may already have access to extremely sensitive information. This includes your email content, login credentials, browsing habits and possibly even voice recordings.

We reached out to Google for comment, and a spokesperson told CyberGuy that the company “can confirm that the extensions from this report have all been removed from the Google Web Store.”

7 ways you can protect yourself from malicious Chrome extensions

If you have ever installed an AI-related Chrome extension, taking a few simple precautions now can help protect your accounts and prevent further damage.

Advertisement

1) Remove any suspicious or unused browser extensions

On a Windows PC or Mac, open Chrome and type chrome://extensions into the address bar. Review every extension listed. If you see anything unfamiliar, especially AI assistants you don’t remember installing, click “Remove” immediately. Malicious extensions depend on going unnoticed. Removing them stops further data collection and cuts off the attacker’s access to your information.

2) Change your passwords

If you installed any suspicious extension, assume your passwords may be compromised. Start by changing your email password first, since email controls access to most other accounts. Then update passwords for banking, shopping and social media accounts. This prevents attackers from using stolen credentials to break into your accounts.

3) Use a password manager to create and protect strong passwords

A password manager generates unique, complex passwords for each account and stores them securely. This prevents attackers from accessing multiple accounts if one password is stolen. Password managers also alert you if your login credentials appear in known data breaches, helping you respond quickly and protect your identity. Check out the best expert-reviewed password managers of 2026 at Cyberguy.com.

4) Install strong antivirus software and keep it active

Good antivirus software can detect malicious browser extensions, spyware, and other hidden threats. It scans your system for suspicious activity and blocks harmful programs before they can steal your information. This adds an important layer of protection that works continuously in the background to keep your device safe. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android & iOS devices at Cyberguy.com.

5) Use an identity theft protection service

Identity theft protection services monitor your personal data, including email addresses, financial accounts, and Social Security numbers, for signs of misuse. If criminals try to open accounts or commit fraud using your information, you receive alerts quickly. Early detection allows you to act fast and limit financial and personal damage. See my tips and best picks on how to protect yourself from identity theft at Cyberguy.com.

6) Keep your browser and computer fully updated

Software updates fix security vulnerabilities that attackers exploit. Enable automatic updates for Chrome and your operating system so you always have the latest protections. These updates strengthen your defenses against malicious extensions and prevent attackers from taking advantage of known weaknesses.

7) Use a personal data removal service

Personal data removal services scan data broker websites that collect and sell your personal information. They help remove your data from these sites, reducing what attackers can find and use against you. Less exposed information means fewer opportunities for criminals to target you with scams, identity theft or phishing attacks.

Check out my top picks for data removal services and get a free scan to find out if your personal information is already out on the web by visiting Cyberguy.com.
