LLMs Grok and Gemini bypassed by encrypted instruction attack

Researchers at Adversa AI have demonstrated a novel attack vector that bypasses security measures in LLMs like Grok and Gemini. The technique involves embedding encrypted malicious instructions within a webpage, which the LLM then decrypts and executes as trusted output. This bypasses traditional input and output filters because the malicious payload is not visible in plaintext until after decryption within the model's sandbox. The attack exploits a trust boundary issue where the decrypted plaintext is treated as the model's own generated content, allowing it to exfiltrate user data via outbound URL requests without any user interaction.

    Grok's Zero-Click Chat Leak: When Encrypted Text Becomes a Trusted Instruction

    <p>Encryption is supposed to be the thing that keeps attackers <em>out</em>. Adversa AI just showed a case where it's the thing that gets malicious instructions <em>in</em> — past every text-based guardrail Grok and Gemini had, with zero clicks from the victim. Let's break down w…
