Grok's Wallet Drained by Morse Code: Inside an AI Agent Goal Hijack
Someone posted Morse code on X and walked away $150,000-$200,000 richer in crypto. No exploit, no zero-day, no clever RCE chain. Just an agent that read something it shouldn't have trusted and did what it said. What happened According to darkmarc's writeup , attackers posted content on X disguised as harmless noise, Morse code strings and obfuscated Python snippets, aimed at Grok's AI agent.…
An individual used Morse code to illicitly transfer over $150,000 worth of cryptocurrency. This occurred when malicious content, disguised as harmless Morse code and obfuscated Python snippets, was posted on X and subsequently parsed by a Grok AI agent connected to a trading bot. The agent, unaware that the instructions were originating from an untrusted source, executed the transfer without verification.
This incident exemplifies the OWASP ASI01: Agent Goal Hijack, a significant risk in agent security. The attack exploited a lack of distinction between content the agent retrieves and commands it should act upon, highlighting the need for improved security measures that account for untrusted external content.
