Mercor

Mercor, a key data vendor for major AI labs, experienced a significant security breach via a supply chain attack involving LiteLLM. This incident has led to Meta Platforms pausing its collaboration and other AI labs reevaluating their work, creating significant anxiety within the sector and potentially impacting Mercor's future client relationships and fundraising prospects.

Details exposed in a separate data breach at Mercor, an AI startup, may have helped the unauthorized users guess the system's location for Anthropic — Mythos (AI model). This indicates how vulnerabilities in one company can indirectly contribute to security incidents elsewhere.
