Pass the Hash Attack Defense: AD Security 101

A pentester describes turning one RCE on an ASP.NET server into deep internal access via mimikatz dumping and password reuse, arguing real engagements must prove impact beyond running whoami.

Pass the Hash lets attackers authenticate with stolen NT hashes instead of plaintext passwords, enabling stealthy lateral movement. The post shows the technique with Cobalt Strike and Mimikatz.

Overpass the Hash converts a captured NTLM hash into fresh Kerberos tickets, giving attackers an authenticated session beyond Pass the Hash. Details the Mimikatz technique, detection, and defenses.

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.

Releases Invoke-DCSync, a PowerShell wrapper around Mimikatz's DCSync feature that impersonates a domain controller to dump account hashes without touching the DC.

Introduces Invoke-MassMimikatz-PsRemoting, which combines SPN discovery, PowerShell Remoting, and Invoke-Mimikatz to harvest credentials from many domain systems automatically.
