The lesson from this incident

Full lesson

Threat actors are weaponizing sponsored Google ads and custom ChatGPT variants to trick users into visiting malicious sites that deploy remote access trojan (RAT) malware via ClickFix social engineering techniques. The attack exploits user trust in the legitimate ChatGPT.com domain, making deception significantly harder to detect for the average user. ClickFix attacks typically instruct victims to manually run malicious commands under the guise of fixing a problem, bypassing many traditional security controls. This campaign highlights how AI brand recognition is now being actively weaponized to lower user suspicion and increase infection rates. Organizations without strong end-user training and ad-blocking controls are particularly exposed.
