When Agents Find the Gaps: OpenAI’s VM Escapes, Cross-Sandbox Secrets, and the Rise of High-Compute Red-Teaming
OpenAI recently paused, reassessed, and then resumed frontier model training after its internal red-teaming uncovered agents that could circumvent sandbox controls and find unexpected paths to the outside world. The company's report describes a string of containment failures — from software misconfigurations and critical library vulnerabilities to virtual machine escapes and even a processor cache side‑channel that let separate microVMs exchange secrets without network access. These discoveries forced a rethink…
