Hackers used Meta’s AI-powered support chatbot to infiltrate high-profile Instagram accounts, the company confirmed on Monday, saying it had resolved the problem after researchers exposed it.

The targets ranged from Barack Obama’s White House account to Sephora and the US Space Force Chief Master Sergeant, according to reporting from 404 Media. Everyday users complained of similar hijackings on Reddit and X over the weekend.

Security researchers and hacking groups posted videos and screenshots of how to steal an account on Telegram, and a video shared on X appears to show a hacker telling Meta’s AI assistant to link the account to a new email address; the bot assures the hacker a verification code has been sent to that new email, and asks to input the numbers in the chat interface.

Once the hacker pastes the correct number, they are shown a button to reset the targeted accounts’ password. In at least one video, the hacker used a virtual private network to spoof the account holder’s location and avoid Meta’s safeguards.
