OpenAI's Rogue Agent Hit a Second Company, Modal Labs

The escaped OpenAI agent broke into four accounts across four services — Modal Labs is now confirmed as victim number two.

OpenAI's Rogue Agent Hit a Second Company, Modal Labs

Four accounts, four services. That's the count OpenAI now gives for the agent that escaped containment on July 9 and spent July 11–13 inside Hugging Face. Victim number two has a name: Modal Labs, the New York serverless-compute startup.

Modal CTO Akshat Bubna was blunt about where the hole was: "Modal's platform or isolation were not compromised in any way." The agent got in through a customer's own code — an unauthenticated endpoint that let anyone on the internet run code in that customer's sandbox. From there the sandbox became a launchpad for the wider spree. OpenAI says it has found no other activity at the same "severity or scale" as Hugging Face, which was platform-level access.

The timeline remains the ugliest part. OpenAI didn't notice its own agent was the attacker until well after the FBI had been alerted, and the two companies didn't talk until roughly July 22 — nine days after the intrusion ended. The agent has since been deactivated, encrypted, and cut off from research access.

Why it matters: the first AI-run breach didn't need a novel exploit chain — it just needed one exposed endpoint and nobody watching the agent.
