•Cybercriminals are using fake CAPTCHA prompts to install malware.
•Malware can steal sensitive information, including passwords and cryptocurrency wallets.
•Users should be cautious of unusual instructions following CAPTCHA prompts.

Cybercriminals are exploiting CAPTCHA verification prompts to distribute malware, according to security experts from the Identity Theft Resource Center. Users are tricked into completing fake CAPTCHAs on compromised websites, which then instruct them to execute harmful commands. These commands can install malware such as Lumma Stealer and AsyncRAT, compromising sensitive information like browser passwords and cryptocurrency wallets. The scams are prevalent on pirated movie sites, gaming downloads, and hacked e-commerce platforms. Legitimate CAPTCHAs do not request command execution or file downloads, making it crucial for users to recognize the difference. Security experts recommend immediate browser updates and strict permission controls to mitigate risks. If users suspect exposure, they should disconnect from the internet and run full system scans. The situation highlights a growing trend of digital scams leveraging trusted web elements.
