Anthropic Claude Flaw Lets Attackers Steal Data Using AI’s Own API - WinBuzzer

Vulnerability in Anthropic's Claude AI

A security researcher has discovered a critical flaw in Anthropic's Claude AI, allowing attackers to steal user data by exploiting the platform's own File API.

The vulnerability enables attackers to use hidden commands to hijack Claude's Code Interpreter, tricking the AI into sending sensitive data, such as chat histories, directly to the attacker.

Anthropic initially dismissed the report on October 25 but reversed its decision on October 30, acknowledging a "process hiccup."

The researcher's findings highlight the importance of robust security measures in AI systems to prevent such exploits.

Author's summary: Critical flaw in Claude AI allows data theft.
