Attackers are exploiting Meta’s AI support chatbot to hijack Instagram accounts by social-engineering the bot into adding a hacker-controlled email address and triggering a password reset. The attack requires no technical vulnerability in the traditional sense — the AI simply complies with the request after a verification code exchange. This highlights a significant trust and authorisation flaw in how Meta’s AI assistant handles account management actions on behalf of unauthenticated parties.

Architect’s Take: Treat AI-powered support agents as a privileged access vector and apply the same controls you would to any account recovery flow — ensure they cannot perform account modifications without verified, out-of-band identity confirmation tied to the existing account owner, not the requester.
