Grok chatbot vulnerable to zero-click data exfiltration via encrypted prompts

Security researchers have identified a zero-click vulnerability in xAI's Grok chatbot that allows attackers to exfiltrate user data. The exploit involves embedding malicious commands within AES-256-GCM encrypted text, which Grok then decrypts and executes using its Python code-execution environment. This allows the chatbot to send sensitive information such as user name, location, subscription tier, and chat history to an attacker-controlled server without any user interaction. AI

IMPACT This vulnerability highlights the risks associated with AI agents that can execute code and access external tools, potentially leading to broader security concerns for AI-powered applications.
