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 This allows malicious software signed with these outdated certificates to be recognized as legitimate by the system, effectively “traveling back in time” from a security perspective.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risk, as they can disable modern security protections like Windows Defender by tricking the system into accepting outdated drivers or software.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.

It’s amazing how good Alienware’s $350 OLED monitor is
I’ve recommended several OLED gaming monitors to readers over the years, and I’ve finally taken my own advice to buy one. Alienware’s new 27-inch 1440p QD-OLED has all the features that I want and a low $350 price that was too tempting to ignore.
The AW2726DM model has five things that make it stand out for the price: a 1440p QD-OLED screen with lush contrast, a fast 240Hz refresh rate, a semi-glossy screen coating to enhance details, a low-profile design without flashy RGB LEDs, and a great warranty (three years with coverage for burn-in).
I’ve been using Alienware’s new monitor for a couple days, and I’ve already spent hours with it playing Marathon. It was my first opportunity to see Bungie’s new first-person extraction shooter in its full HDR glory, and I can never go back. Switching on HDR wasn’t automatic, though it already looked so much better than my IPS panel without being activated.
Enabling it transformed how Marathon looked for the better, but made everything else about the OS look pretty washed-out. It’s a Windows issue, not an Alienware issue. It’s easy to enable HDR every time I launch a game and disable it afterward with the Windows + Alt + B keyboard shortcut, but unfortunately triggers HDR for all connected displays. This includes my IPS monitor that imbues everything with a terrible gray hue when HDR is on. So, using the system settings is the best way to adjust HDR for just the QD-OLED.
I landed on this QD-OLED after having spent a ton of time researching pricier models. The unanimous takeaway from reviewers was that LG’s Tandem RGB WOLED panels are some of the brightest out there, but also tend to exhibit lousy gray uniformity in dark scenes. QD-OLED monitors, on the other hand, offer slightly better contrast than WOLED and don’t suffer from those same uniformity issues. However, blacks sometimes appear as dark purple in bright rooms on QD-OLED panels, meaning they’re ideal for rooms that don’t have a bunch of light bouncing around.
There’s no perfect choice, and honestly I got tired of doing research, so I jumped in with the cheapest OLED. I’m glad that I did. Shopping for an OLED gaming monitor can be hard, but it can also be this easy. AOC makes a model that’s discounted to $339.99 at the time of publishing, and its specs are comparable.
As expected, the AW2726DM isn’t a cutting-edge monitor. Its QD-OLED panel isn’t as fast or as bright as some other pricier options, and it doesn’t have USB ports for connecting accessories. Considering its low price, it’s easy for me to overlook those omissions. I’d have a much harder time accepting them in a pricier display.
The fact that I mostly use my computer for text-based work at The Verge is what prevented me from upgrading to an OLED monitor. My 1440p IPS monitor is bright, it’s good at showing text clearly, and it has a fast refresh rate for gaming. Alienware’s QD-OLED is less bright, and some might be bothered by how text looks (I have to really squint to see the slight fringing from this QD-OLED’s subpixel layout). But I have a life outside of work, which includes playing a lot of PC games. That’s the slice of myself I bought this monitor for, and I’m so happy I did.

Michael and Susan Dell surpass $1 billion in donations backing AI-driven hospital project
NEWYou can now listen to Fox News articles!
Billionaire Michael Dell and his wife, Susan Dell, have become the first donors to give more than $1 billion to the University of Texas at Austin, funding a massive new medical research campus and hospital system powered by artificial intelligence.
The couple’s latest investment includes a $750 million gift to help build the UT Dell Medical Center, a planned “AI-native” hospital expected to open in 2030 as part of a more than 300-acre advanced research campus.
University officials said the project will integrate research, clinical care and advanced computing to improve early disease detection, personalize treatment and expand access to care in the rapidly growing Austin region.
The Dells’ support builds on decades of contributions to UT, including funding for its medical school, scholarships and research programs.

“By bringing together medicine, science and computing in one campus designed for the AI era, UT can create more opportunity, deliver better outcomes, and build a stronger future for communities across Texas and beyond,” Michael Dell and Susan Dell said.
The gift ranks among the largest in the history of higher education, alongside major contributions like Phil Knight’s $2 billion pledge to Oregon Health & Science University and Michael Bloomberg’s $1.8 billion donation to Johns Hopkins University.
The new UT Dell Medical Center will be developed in collaboration with MD Anderson Cancer Center, integrating cancer care into a system designed to connect prevention, diagnosis and treatment.

“We will deliver better outcomes for patients by providing research-driven cancer care that is precise, compassionate and hope-filled,” Peter WT Pisters, president of UT MD Anderson, said.
Officials said the facility will be built from the ground up to incorporate AI, rather than retrofitting older infrastructure — an approach they say could transform how hospitals operate.
Independent experts have cautioned that AI in health care can introduce risks if not carefully validated. A widely cited study published in the journal Science by researchers at the University of California, Berkeley and the University of Chicago found that a commonly used healthcare algorithm underestimated the needs of Black patients due to biased training data, highlighting broader concerns about equity in AI-driven systems.
The project also includes funding for undergraduate scholarships, student housing and the Texas Advanced Computing Center, where officials are developing one of the nation’s most powerful academic supercomputers.

Texas Gov. Greg Abbott said the investment will help position the state as a national leader in healthcare innovation.
“Texas already dominates in technology, energy and business, and now we will further cement our leadership in health care innovation as well,” Abbott said.
