The Credential Layer Is Expanding Faster Than Security Teams Can See It

**GitGuardian: The credential layer is the primary attack surface to secure.** This article explains how accelerating software production, developer endpoints, collaboration systems, and AI agents expand credential exposure, cites infostealer supply-chain campaigns (e.g., Shai-Hulud) that compromised thousands of systems and tens of thousands of secrets, and argues that organizations must detect, remediate, and prevent credential leaks by inventorying secrets across repositories, endpoints, and public exposure with contextual information (validity, ownership, permissions, dependencies).
