If Microsoft Entra Seamless SSO is enabled and the AZUREADSSOACC$ Kerberos key is compromised, an attacker can forge a Silver Ticket for the HTTP/autologon.microsoftazuread-sso.com service and request an Entra token as a synchronized on-premises identity. Resulting access is bounded by that identity's roles and resource permissions; Conditional Access can require additional proof, including MFA, so the technique does not guarantee MFA bypass.
