ClickFix Walkthrough: How Fake CAPTCHAs Hack You

Microsoft says 47% of the hacks they investigated last year started with a fake CAPTCHA. This is what one looks like from the victim's seat. In this walkthrough we follow someone who searches for a free PDF editor, clicks the top result, hits a fake CAPTCHA, follows its "verification" steps, and three keystrokes later their computer has been quietly compromised. No browser warning, no antivirus alert, no sign anything went wrong. The technique is called ClickFix. The 47% number comes from Microsoft's 2025 Digital Defense Report. By Microsoft's count, ClickFix was the number-one way attackers got into systems their response team handled over the past year. Part 2 walks through what was actually happening at each step.
