Concrete attack paths, working tools, and specific misconfigs decide what to watch: live demos of device code fishing and evil gen X phishing that steal cookies and MFA tokens, road recon enumeration of conditional access, MSBuild-based binary drops on Azure VMs to run as SYSTEM, and Seamless SSO/DCsync abuse to swap on‑prem hashes into Entra ID and request PIM to become Global Admin. Detections tested: Defender for Cloud gaps, token broker caches, and why directory readwriteall and default device registration routinely break defenses.
