MITRE ATT&CK T1078 Valid Accounts Explained

This report analyzes MITRE ATT&CK T1078 (Valid Accounts) and its four sub-techniques (default, domain, local, cloud), documents real-world abuse by multiple ransomware groups and APTs (e.g., DragonForce, Scattered Spider, Silk Typhoon, WARP PANDA), and highlights that credential-based access is highly effective and difficult to detect (citing a 98% success rate in tests). It emphasizes identity and cloud accounts as primary attack surfaces, details common adversary behaviors (credential theft, MFA abuse, service principal/OAuth misuse), and recommends validating identity-abuse paths rather than relying solely on vulnerability severity scoring.
