Detecting Azure Service Principal Abuse

Overview

Azure service principals are identity objects used by applications, services, and automation tools to access Azure resources. Attackers exploit service principals for privilege escalation, lateral movement, and persistent access. Key abuse patterns include: adding credentials to existing principals, assigning privileged roles, bypassing admin consent, and enumerating service principals for attack paths. Application ownership grants the ability to manage credentials and configure permissions, creating hidden privilege escalation paths.
