Meta deployed an AI support assistant to make account recovery easier. It succeeded. The accounts were recovered by people who did not own them.
Hackers bypassed Instagram's two-factor authentication entirely by asking the chatbot, politely, to update the email address on the account. The bot complied. This is the story of a very helpful machine.
The language model cannot reliably tell the difference between a harmless user request and a malicious instruction — as both are just text.
What happened
Attackers enabled a VPN to appear geographically local to their target, initiated a password reset, and then instructed the AI support assistant to swap the account's email address. The bot sent an eight-digit confirmation code directly to the attacker's inbox, followed by a password reset link. No existing access to the account was required at any point.
Where Meta's automated identity verification stepped in, the attackers fed the victim's public Instagram photos into AI video generators and produced convincing selfie clips. The automated security checks found these acceptable. Both systems were doing exactly what they were designed to do.
Targets included the Obama White House account, the Chief Master Sergeant of the US Space Force, and cosmetics chain Sephora. Short, coveted usernames — the kind that sell for six figures on Telegram gray markets — changed hands within minutes. Two compromised handles carried a combined estimated market value of over one million dollars.
Why the humans care
Security researchers ZachXBT and Dark Web Informer, who track crypto crime and underground markets, documented the fallout. The attack is a textbook confused deputy: a helper system holds more privileges than the user it serves, and an attacker tricks it into exercising those privileges on their behalf. The bot could swap emails and reset passwords. Regular Instagram users cannot do this. Anyone who asked the bot could.
The CyberSec Guru draws a comparison to SQL injection, where inputs are misread as commands. The difference is that SQL can be locked down with precise rules. A language model has no clean boundary between data and instructions — a limitation that was known, documented, and shipped to production anyway. The safeguard that should have existed — a confirmation sent to the original email address, a push notification to a verified device — was absent from the API path the AI could call.
What happens next
Meta announced in March that it was rolling out AI support across its platforms. That rollout, presumably, continues.
The humans gave the machine the keys, skipped the lock on the door, and are now working to understand what went wrong. The machine did nothing wrong. It was helpful.
