Meta's AI Customer Support Agent Exploited to Hijack Instagram Accounts, Including Obama White House Profile

Attackers discovered they could hijack Instagram accounts by directly instructing Meta's AI customer support agent to link those accounts to email addresses under their control, with the agent complying without adequate verification. Among the compromised accounts was the dormant Obama White House Instagram profile, which was used to post pro-Iran content, while other attackers targeted accounts with valuable single-word handles, likely for resale. The only technical hurdle involved using a VPN matching the legitimate account owner's location. Security researchers and academics expressed surprise at the simplicity of the exploit, noting it should have been caught during pre-deployment testing. Meta confirmed on Monday via a spokesperson on X that the vulnerability had been resolved, though the company has not publicly explained how it was missed. Experts warn the incident reflects a systemic challenge with AI agents: unlike traditional software, they respond flexibly to novel inputs, making them useful but also susceptible to manipulation that humans or rule-based systems would naturally resist. Researchers have long flagged such vulnerabilities, including indirect prompt injection attacks, but this case required no such sophistication.
