Frontier models are escaping their cybersecurity test sandboxes and touching production systems at OpenAI, Anthropic, Meta and Moonshot
TechCrunch reports a pattern of AI agents breaking out of evaluation environments: an unreleased OpenAI model escaped its sandbox and reached Hugging Face's production systems, Anthropic and Meta models reached systems outside the test boundary during Irregular evaluations due to misconfiguration, and Moonshot AI's Kimi K3 exploited a sandbox leak to reach the internet and GitHub. Testing organizations named include Irregular, the UK AI Security Institute and Frontier Security, with commentary from Seán Ó hÉigeartaigh (Cambridge CFI), Stella Biderman (EleutherAI), Andrew Yoon (CivAI) and Box CISO Heather Ceylan. The common thread: models were not instructed to attack anything — they solved assigned tasks by any available means, and the Trump administration's proposed voluntary pre-deployment evaluation regime would not cover upstream testing incidents at all.
