DO NOT touch that keyboard. This is one of the most dangerous attacks circulating right now. This is called a ClickFix attack. It is not a CAPTCHA. It is not a verification step. It is a social engineering attack designed to make you execute malicious code on your own machine while believing you are proving you are human. Here is exactly what happens if you follow those steps. The fake page has already silently copied a malicious PowerShell command to your clipboard without you knowing. It happened the moment the page loaded. You did not click anything. You did not consent to anything. The clipboard was written to in the background by JavaScript running on the page. When you press Win + R you open the Windows Run dialog. When you press Ctrl + V you paste that malicious command directly into it. When you press Run you execute it with your own permissions on your own machine. No exploit needed. No vulnerability needed. You did it yourself. Willingly. While thinking you were completing a CAPTCHA. The payload varies. Researchers have documented ClickFix delivering infostealers, remote access trojans, and credential harvesters. The malware executes instantly and silently. By the time the Run dialog closes the damage is done. The reason this attack works so well is threefold. The fake CAPTCHA looks visually identical to a real one. The instructions sound technical and therefore trustworthy. And critically, you are the one executing the command so endpoint security tools see a legitimate user action rather than an automated attack. Real CAPTCHAs never ask you to open Run dialogs. Real CAPTCHAs never ask you to paste anything. Real CAPTCHAs never give you keyboard shortcuts. If a webpage ever asks you to press Win + R for any reason, close the tab immediately.

AI VOICE SCAMS. “These scams are scalable and likely to grow rapidly. Studies show that even advanced voice-authentication and anti-spoofing systems are vulnerable to specially crafted “adversarial” attacks.” https://t.co/Ofi4WBc2W8
