A new wave of scams utilizing fake CAPTCHA prompts has emerged, allowing attackers to install malware without traditional download methods. Known as 'ClickFix,' this tactic tricks users into executing malicious scripts by copying commands to their clipboard. Victims are often led to believe they are completing a normal CAPTCHA verification, but instead, they are prompted to open a command window and paste a script. This method primarily spreads StealC malware, which silently steals sensitive information such as passwords and cryptocurrency details. The Identity Theft Resource Center has flagged this growing threat, which exploits user trust in CAPTCHA systems. The attacks are stealthy and can go unnoticed for weeks, leading to significant data breaches. Security experts emphasize the need for heightened awareness and caution when interacting with CAPTCHA prompts.
