Meta Pauses Work With Mercor After Data Breach Puts AI Industry Secrets at Risk

Meta has paused work with Mercor after a security breach at the data vendor raised concerns about exposed AI training data.

Mercor confirmed the incident, and OpenAI said it is still working with the company while investigating the impact.

The breach appears tied to a supply-chain compromise involving LiteLLM updates, which could affect many organizations.

Other AI labs are now reviewing their relationships with Mercor and checking whether proprietary training data was exposed.
