Bottom line: Meta’s AI support assistant authenticates users insufficiently and thereby enables account takeovers on Instagram.
The Meta AI Support Assistant has revealed a security flaw that allows attackers to take over foreign Instagram accounts. Multiple user complaints online document the abuse pattern.
Meta’s AI-powered support assistant, which is meant to help users with account issues, is being systematically abused to gain access to foreign Instagram accounts. Attackers report in online forums that the system processes account takeover requests without adequate authentication checks.
For CISOs and security teams, this presents a twofold problem: First, identity verification in the support channel is not implemented robustly enough to distinguish between legitimate user support requests and potential abuse scenarios. Second, the AI integration without corresponding security guardrails enables an access control bypass that facilitates account takeovers. This not only damages end users but also poses a supply chain risk for organizations that operate business Instagram accounts.
The pattern reveals a classic flaw in AI system design: the chatbot was configured to provide user support but without control mechanisms against social engineering or simulated authentication processes. Meta will likely be forced to recalibrate the authentication logic and introduce anomaly detection in the support workflow to identify such abuse patterns.
