How LiteLLM Turned Developer Machines Into Credential Vaults for Attackers

In March 2026, threat actor TeamPCP executed a supply chain attack targeting developer workstations, leveraging LiteLLM infrastructure to harvest credentials. Developer machines proved to be high-value targets due to their role as credential hubs for testing, caching, and reuse across services, bots, build tools, and AI agents. The attack demonstrates the increased risk posed by developer environments that lack the security controls applied to production systems. Organizations should implement strict credential management, minimize credential caching on developer machines, apply principle of least privilege, and monitor for unusual access patterns from development environments. Supply chain integrity and developer workstation security require urgent attention in enterprise security programs.

The most active piece of enterprise infrastructure in the company is the developer workstation. That laptop is where credentials are created, tested, cached, copied, and reused across services, bots, build tools, and now local AI agents. In March 2026, the TeamPCP threat actor proved just how valuable developer machines are. Their supply chain attack on
