1. Spins up an SMB server and waits for an incoming SMB connection
2. The incoming credentials are relayed to a specified target, creating a connection with the context of the relayed user
3. Queries are made down the SMB connection to the lsarpc pipe to get the list of domain usernames. This is done by cycling up to 50000 RIDs

Dependencies

• Python 2.7 (sorry but impacket doesn't play nice with 3 :( )
• Impacket v0.9.17 or above

Installation

pipenv install --two
 pipenv shell
 
 # Optional: Run if installing impacket
 git submodule update --init --recursive
 cd submodules/impacket
 python setup.py install
 cd ../..

Usage
First, find a target host to relay to. The target must be a member of the domain and MUST have SMB Signin off. CrackMapExec can get this info for you very quick!
Start RidRelay pointing to the target:

python ridrelay.py -t 10.0.0.50

OR
Also output usernames to file

python ridrelay.py -t 10.0.0.50 -o path_to_output.txt

Highly Recommended: Start Responder to trick users to connecting to RidRelay

TODO:

• Add password policy enumeration
• Dynamic relaying based on where incoming creds have admin rights
• Getting active sessions???
• Connect with Bloodhound???
