Operation: ClickFix
ClickFix is a social engineering technique where a malicious webpage tricks users into manually running a command on their own machine. Typically by: Displaying a fake error or verification prompt Silently copying a malicious command to the clipboard (document.execCommand("copy")) Instructing the user to paste and run it (e.g., in Run dialog, PowerShell, or Terminal) It's dangerous precisely because the user executes the payload themselves, bypassing many endpoint controls.
Our threat intelligence unit has been tracking a phishing campaign quietly spreading across the web. The actor is running a network of fake reCAPTCHA verification pages. Convincing enough to trick everyday users into thinking they’re completing a routine bot check.
What caught our eye was the hosting pattern. The page we flagged sits behind a well-known German hosting provider. the kind of infrastructure that blends in with legitimate traffic. It’s indexed in public scan databases, but there are thousands of lookalike pages out there. You’ll need to know exactly what you’re looking for to find the right one among them.
Once a victim lands on the page, something is silently loaded into their clipboard. Dressed up as a harmless verification step. My advice: look, don’t touch. The scan record itself already tells you everything you need. You don’t have to go anywhere near the live page.
The script the page points to was pulled offline shortly after we flagged it. The direct link returns nothing now. But the internet has a long memory -and if you know where to look, deleted doesn’t always mean gone.
Inside the recovered file, the actor took care to hide their tracks. Every sensitive string is encoded, every path is buried. Peel back the layers one by one. The last one leads straight to the server used to drop the final payload onto the victim’s machine.
