The numbers tell one story. Mercor’s security incident may have exposed sensitive data from its customers, including Anthropic, OpenAI, and Meta. The breach was linked to a supply chain attack on LiteLLM, a tool used by developers to plug their applications into AI services. TeamPCP, a hacking group, planted malicious code inside LiteLLM, which was downloaded millions of times per day. Mercor’s $10 billion valuation and high-profile customers make this incident a significant concern.
When a startup with a $10 billion valuation says “the privacy and security of our customers and contractors is foundational to everything we do,” it sounds like a promise that’s already been broken.
