It's not just annoying — it's dangerous

CAPTCHA isn't just an annoying obstacle to access certain sites anymore — attackers are now using it to break into your computer.

CAPTCHA isn't just an annoying obstacle to access certain sites anymore — attackers are now using it to break into your computer. Yes, really: the "I'm not a robot" feature has become another way to get hacked, but it's pretty easy to avoid.

How does it work?

It works simply: the attacker sets up a fake site, a CAPTCHA pops up, you click it, and then a message pops up along the lines of "press Win + R, press Ctrl + V, and Enter." That opens PowerShell and downloads a virus (most likely a Trojan) automatically.

How to prevent it?

Very simple: as soon as anyone or anything asks you to type or paste a command into PowerShell, just don't. You also wouldn't give a thief on the phone your home address along with the precise location of the spare key.
