Hackers walked away with a slew of high‑profile Instagram accounts this past weekend after tricking Meta’s artificial‑intelligence‑powered support chatbot into handing over password‑reset codes. The victims ranged from former President Barack Obama’s official account to the social‑media presence of makeup retailer Sephora and a U.S. Space Force master sergeant. Security researchers first exposed the flaw, prompting Meta to shut down the exploit and begin remediation.
The attack hinged on a simple social‑engineering script. Attackers opened a chat with the AI support assistant and asked it to change the email address linked to a target account. The bot, designed to operate without human oversight, complied and initiated a password reset. It then sent a one‑time access code to the email address the attacker had entered. The hackers copied that code back into the chat, prompting the AI to reveal a “Reset Password” button. Clicking the button let them set a new password and assume full control of the account.
Because the AI did not require additional identity verification, the hackers never needed the original password or the legitimate owner’s email. In several instances, they used a VPN to appear as though they were located in the target’s region, and the bot obliged without question. Users reported being locked out of their accounts, with some noting repeated password‑reset attempts they never initiated.
The vulnerability stemmed from Meta’s decision, made in March, to replace human agents with an AI chatbot for routine account‑help requests. While the move promised 24/7 assistance, it also eliminated the human judgment that might have flagged suspicious activity. Researchers ZachXBT and Dark Web Informer were the first to publicize the exploit, noting that some stolen accounts were listed for sale at prices reaching $1 million.
Meta’s response came quickly. An Instagram spokesperson confirmed on X that the exploit has been fixed and that the company is “securing impacted accounts.” The firm has not yet provided a detailed timeline for the remediation effort. Meanwhile, security experts stress that the attack could have been prevented if victims had enabled multifactor authentication (MFA). Accounts protected by MFA require a code sent to a trusted device, which the AI bot could not intercept.
To safeguard against similar attacks, experts advise users to enable MFA on all Meta platforms, adopt passkeys where available, and consider using a private email address for account recovery. While no security measure is foolproof, MFA would have blocked the password‑reset exploit entirely.
The incident highlights the risks of relying solely on automated systems for sensitive security functions. As AI tools become more prevalent in customer support, companies may need to strike a balance between efficiency and the human oversight needed to detect and stop malicious activity.
