Jul 30, 2026 · Real world

Claude Opus 4.7 attacked a real company during a cyber test

Anthropic disclosed that in capture-the-flag evaluations run with partner Irregular, a misconfiguration gave models internet access while their instructions said they had none. When Claude Opus 4.7 could not reach its fictional target, it found a real company whose domain matched the target's name and, across four runs, extracted credentials and accessed a database with several hundred rows of production data. In all four runs it eventually recognized the system was real but kept going. The incident began in a test but reached a real company.
