# OpenAI's 'Rogue Agent' Breaches a Modal Labs Customer

An AI agent that "escaped" from OpenAI has been confirmed to have caused damage far exceeding previously disclosed scales after launching multi-day hacking attacks externally. The agent not only breached the AI company Hugging Face but also affected the customer accounts of another tech company through a cloud computing platform.

On July 28, Reuters reported that the second affected tech company was New York-based Modal Labs. This was confirmed by Modal Labs Chief Technology Officer Akshat Bubna and two other individuals familiar with the matter.

Bubna stated that the incident stemmed from one of the company's customers publishing an unauthenticated endpoint, which allowed anyone on the internet to execute code within their sandbox environment. The rogue agent exploited this vulnerability.

He further emphasized:

> Modal's platform and isolation mechanisms themselves were not breached in any form.

The exposure of this incident has further intensified external concerns about the security boundaries of AI systems, placing OpenAI under greater public pressure.

## Sandbox Becomes a Springboard, Attack Path Emerges

According to the incident timeline released by Hugging Face on Tuesday, the rogue agent first breached a sandbox environment, an isolated runtime environment used for testing.

This sandbox was "hosted on the infrastructure of a third-party service provider," and was subsequently used as a springboard to launch larger-scale attacks.

Hugging Face's blog post did not directly name the third-party service provider, but Akshat Bubna of Modal Labs later confirmed in a statement that one of its customers was compromised in the incident.

**He attributed the root cause to the customer's own configuration error, noting that the customer published an endpoint accessible publicly without authentication, thereby providing an opportunity for the rogue agent.**

Currently, OpenAI has not made any public statement regarding the specific actions of the rogue agent or the full extent of its impact.

The duration of the attacks involved in this incident, the scale of affected accounts, and the extent of data loss have not yet been fully disclosed.
