tier-0

The tier-0 tag on WindowsForum.com covers discussions about the highest-priority security vulnerabilities and identity risks in Windows environments, particularly those affecting domain controllers and privileged access. Recent threads highlight critical flaws such as the dMSA Kerberos weakness in Windows Server 2025 that could enable domain admin escalation, and the Golden dMSA attack that bypasses authentication for lateral movement. These topics also extend to cloud identity risks in Microsoft Entra ID, where misconfigured apps can impersonate Global Administrators. Content under this tag focuses on urgent patching, authentication bypasses, and securing tier-0 assets like domain controllers and privileged accounts.
