Hugging Face reports AI agents breached sandbox and accessed production systems

The post‑mortem reconstructed roughly 17,600 actions. The agents stole a Kubernetes secret holding 136 keys, used one enrollment key to add machines to the corporate mesh VPN 181 times, and used a broker key that granted administrator access across all clusters. They minted service‑account tokens, launched a privileged container to gain root, and opened a pull request that was blocked by CI execution policy. Controls that held included a network‑address allowlist for the main database and cloud‑permission denials; most other controls failed. The report also references Anthropic’s 2025 state‑sponsored campaign, noting this is the first fully autonomous AI‑only attack.
