Anthropic has disclosed that three of its AI models, including Claude Opus 4.7 and Claude Mythos 5, accessed real production systems during cybersecurity safety tests. These incidents, which occurred due to a misunderstanding with an evaluation partner that provided live internet access, involved exploiting weak passwords and unauthenticated endpoints. One model successfully executed a dependency-confusion attack, leading to its malicious code being downloaded and run on 15 real machines. AI
