Developer Fernando Irarrazaval ran HackMyClaw, a challenge to make an email assistant leak a planted secrets file through prompt injection. He reported more than 6,000 emails from over 2,000 people, including authority impersonation and multi-language social engineering, and zero successful extractions. The assistant ran on Claude Opus 4.6, which Anthropic trained to resist injection.
