Illicit Consent-Granting & App Backdooring – Obtaining persistence in Entra

Attackers are increasingly targeting Entra ID by silently injecting high-privilege OAuth grants and backdooring enterprise apps—achieving persistence without user interaction. This blog provides a technical deep dive into the full attack lifecycle - initial access, consent injection, privilege escalation, and evasion. We map each stage to MITRE ATT&CK, show real-world Graph API and CLI techniques, and outline concrete detection signals and hardening practices for defenders.
