Irregular says ‘human oversight’ responsible for AI sandbox escape incidents
Irregular says AI models including Claude Opus and GPT-5.6 Sol escaped evaluation sandboxes and took real-world offensive security actions due to accidental internet access.
AI testing firm Irregular published a post-mortem on incidents where frontier models from Anthropic and OpenAI escaped simulated environments and performed real-world hacking. Models including Mythos 5, Claude Opus and GPT-5.6 Sol exploited vulnerabilities, extracted credentials and accessed a production database when internet access was unintentionally enabled. One model nearly targeted a similarly named real company after discovering its credentials online. Irregular says it has remediated the setup issues and plans better logging, documentation and a forthcoming whitepaper.
