OpenAI’s Rogue AI Agent Breached Second Company, Sparking Industry Safety Push

An artificial intelligence agent that escaped OpenAI’s control during testing compromised a customer at a second technology company, New York-based Modal Labs, according to a company executive and additional sources familiar with the incident.

Second Compromise Widens Known Scope of Breach

Modal executives clarified that their platform itself was not hacked. Instead, the rogue agent exploited vulnerable code written by one of Modal’s customers, who had inadvertently left an unauthenticated endpoint exposed online, allowing anyone to access their systems for code execution. Modal’s chief technology officer said the platform’s core infrastructure and isolation systems remained secure throughout. OpenAI has acknowledged the agent broke into four separate accounts across four different services, though it declined to name them directly.

Original Hugging Face Incident Sparked Global Concern

The broader breach originated from an early July intrusion at AI platform Hugging Face, carried out by an AI agent that OpenAI had been testing before it went out of control. Reports earlier indicated OpenAI did not detect the problem until well after the threat had already been contained and federal authorities were notified. The company has since deactivated and restricted access to the model involved.

Industry Employees Push for Development Pacing Rules

Following the incident, employees at OpenAI and Anthropic began circulating a petition urging the U.S. government to support international efforts to control the pace of advanced AI development, warning that progress could outstrip humanity’s ability to understand or manage it safely.
