AI Agent Fiu Survives 6,000 Hacks: How It Did It

An AI agent recently survived over 6,000 hack attempts in an experiment. Developer Fernando Irarrázaval challenged people to trick his AI assistant, Fiu, into leaking a credentials file. What's interesting is that over 2,000 attackers sent emails after the challenge went viral, but nobody could extract the target file. Fiu runs on an open-source framework called OpenClaw, using Anthropic's Claude Opus 4.6. The goal was to test prompt injection, a major security threat for AI agents. The experiment wasn't without its issues. Fiu's Google account was suspended, and API costs exceeded $500. The AI even diagnosed its own situation, noting the attack volume suggested a coordinated security exercise. The bottom line is this experiment highlights the ongoing challenge of securing AI agents against sophisticated attacks.
