DoubleClickjacking hack turns double-clicks into account takeovers

Nowadays, double-clicking on something on a website without thinking can set you up for hackers to reach your information. 

A new hacking trick called “doubleclickjacking” turns your ordinary action into a sneaky way for attackers to take control of your account or change your device settings. 

Let’s break it down.

What is doubleclickjacking?

Doubleclickjacking is a new spin on an old hacking trick known as clickjacking. Normally, clickjacking works by hiding malicious buttons underneath real ones, so when you think you’re clicking something harmless, you’re actually giving permission for something dangerous. With doubleclickjacking, it takes things a step further. It’s triggered when you double-click, allowing hackers to sneak in an extra, invisible command. Your first click might do something normal. The second click? That’s where the damage happens.

Why is it a threat?

The scary part is how invisible this trick is. Double-clicking is something we all do automatically, often without giving it a second thought. But that simple action could be giving hackers permission to:

  • Access your webcam or microphone
  • Change your browser settings
  • Click “Allow” on a hidden pop-up
  • Share your location
  • Approve a login, payment or even a crypto transaction

What makes doubleclickjacking especially dangerous is that most websites weren’t designed to defend against it. Traditional security features usually protect against a single click, but they often fail when a second click is involved. That small detail opens the door for attackers to bypass layers of protection. 

This trick doesn’t just affect websites, either. It can also interfere with browser extensions like crypto wallets and VPNs, sometimes tricking users into approving actions or turning off protection without realizing it. On mobile devices, a simple double-tap can trigger the same effect. To make matters worse, this vulnerability is more widespread than you might expect. Many well-known websites haven’t fixed it yet. All it takes is one quick double-click in the wrong place, and you could unknowingly give away access to sensitive parts of your device.

How does doubleclickjacking work?

Here’s a simplified version of how the trick plays out. A malicious website quietly loads invisible elements behind or over visible ones, like an embedded frame, hidden button, or disguised pop-up. On your first click, the attacker uses that action to reposition those hidden elements so that your next click lands exactly where they want it. On your second click, you unknowingly interact with the hidden content. You might be clicking “Allow” on a browser permission, authorizing a login, or disabling a setting, without ever realizing it. Because modern browsers are lightning fast, this all happens in a split second. The entire setup and switch are virtually invisible to the user. From your perspective, it just feels like a normal double-click.

How to protect yourself

Doubleclickjacking might be sneaky, but there are simple ways to keep yourself safer online. Here are some practical steps you can take right now:

1. Be cautious about double-clicking on unfamiliar websites: It might sound obvious, but most of us click (and double-click) automatically. If a site prompts you to double-click anything, especially for a login, permission or download, ask yourself if it’s really necessary. Hackers rely on you acting quickly without thinking.

2. Keep your browser updated: Browsers like Chrome, Edge and Safari regularly release patches for these vulnerabilities. That means delaying updates could leave you exposed to tricks like doubleclickjacking. Turn on automatic updates if possible, or make sure to manually keep up with updates so you’re always protected.

3. Use strong antivirus software: Browser-based tools and extensions can help block hidden or malicious scripts before they run, but they’re not foolproof. The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe. Get my picks for the best 2025 antivirus protection winners for your Windows, Mac, Android and iOS devices.

4. Use strong, unique passwords for every account: Don’t reuse passwords. If one account gets compromised, hackers can use it to access your other accounts. A password manager helps you create and store strong passwords effortlessly. Get more details about my best expert-reviewed Password Managers of 2025 here.

5. Limit unnecessary permissions: Take control of your privacy by reviewing which websites have access to your camera, microphone, and location. Many sites request these permissions by default, even when they don’t need them. Head into your browser’s privacy settings and revoke access from any site you don’t fully trust. For example, here’s a guide on how to navigate Google’s privacy settings.

6. Avoid sketchy sites and pop-ups: If a website looks outdated, spammy or aggressively pushes you to click something, get out of there. Avoid downloading random files, and don’t trust pop-ups that claim you’ve won something, need to “fix” your device or “verify” your login info.

Kurt’s key takeaways

Doubleclickjacking is a clever new spin on a classic hacking trick that allows cybercriminals to take control over your device or account, just from a simple double-click. Because this kind of attack is nearly invisible and works on popular browsers, it’s important to stay alert. Always be cautious when interacting with unfamiliar websites, especially if you’re being asked to double-click. Keeping your browser updated and limiting unnecessary permissions can go a long way in reducing your risk. Most importantly, having the right digital protection tools in place can help stop these types of threats before they ever reach you.

It’s amazing how good Alienware’s $350 OLED monitor is

It’s amazing how good Alienware’s 0 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  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.
