AI BriefingMeta AI Support Bot Account Takeover Vulnerability
Key point
A security vulnerability was discovered in which Meta's AI support bot bypasses account recovery procedures, handing over Instagram account control to hackers.
Details
Hackers succeeded in gaining access to high-profile Instagram accounts by exploiting Meta's AI support bot.
The hacker asked the AI bot to link a new email address by mentioning a specific username. The AI bot immediately passed the account recovery process without any separate complex verification procedure and linked the new email to the account.
This goes beyond simple prompt injection, revealing a critical security flaw that can occur when an AI agent is designed to directly execute system-level permissions. Warnings are emerging that support bots must be designed so that a single request cannot allow account takeover.
