Kerberos at the Company Party

Semperis argues AI-driven attacks are outpacing identity teams as machine identities outnumber human ones 10:1, and urges building organization-wide cyber resilience around hybrid identity protection before the next crisis.

Syncing Domain Admins into Entra ID lets attackers pivot from compromised on-prem AD to the cloud, and back via password writeback. CIS and Microsoft advise keeping privileged admin accounts cloud-only.

SpecterOps argues identity risk now extends beyond Tier Zero, as attackers increasingly use legitimate credentials and trusted relationships to reach backups, regulated data, and other critical workloads.

Semperis introduces Migrator for Active Directory 2.0, an update aimed at helping organizations move Active Directory environments with confidence and greater operational control.

Unconstrained delegation lets a service impersonate users across the domain; attackers hunt such servers, capture Kerberos TGTs with Rubeus, and move laterally. Mechanics and remediation covered.

AS-REP Roasting targets accounts with Kerberos pre-authentication disabled: attackers request an encrypted response and crack it offline. The post shows finding and fixing them with Purple Knight.
