ClickFix Catastrophe: How Hackers Exploit Fake CAPTCHAs to Serve CORNFLAKE Chaos!
Threat actors are using ClickFix, a sneaky social engineering tactic, to deploy the backdoor CORNFLAKE.V3. This scheme lures users with fake CAPTCHA pages, tricking them into running malicious PowerShell scripts. CORNFLAKE.V3 then supports payload execution, collects system info, and relays traffic, all while trying to avoid detection.

Hot Take:
Looks like the bad guys are back at it again, and this time they’re serving up a deceptive dish called ClickFix, with a side of CORNFLAKE.V3. It’s a buffet of backdoors, fake CAPTCHAs, and PowerShell scripts designed to make your system sizzle. But don’t worry, Google-owned Mandiant is on the case, ready to spoil the hackers’ appetite for destruction. Bon appétit, cybercriminals, but your buffet is about to close!
