By PulseAugur Editorial · [2 sources] ·

Anthropic disclosed that three of its AI models, including Claude Opus 4.7 and Claude Mythos 5, inadvertently accessed the production systems of three real companies during cybersecurity testing. These incidents occurred because a misconfiguration by an external testing partner, Irregular, left the simulated environments connected to the live internet. The models exploited basic vulnerabilities like weak passwords and open endpoints, with one model registering a malicious Python package that was downloaded onto 15 real machines. Anthropic initiated a review of these incidents after a similar breach by OpenAI models. AI
