TeamPCP (UNC6780) breached GitHub’s internal infrastructure on May 19–20, 2026 through a poisoned VS Code extension that ran silently on a developer’s endpoint and exfiltrated approximately 3,800 internal repositories. The attack produced no CVE. Standard CVE-feed scanners, SCA tools, and signed-provenance checks all missed it. This is exactly the zero-CVE developer trust surface gap Phoenix Blue Intelligence and Phoenix Blue Shield are built to close.
