Cypherhound - Terminal Application That Contains 260+ Neo4j Cyphers For BloodHound Data Sets ~ Hacking

A Python3 terminal application that contains 260+ Neo4j cyphers for BloodHound data sets.

Why?

BloodHound is a staple tool for every red teamer. However, there are some negative side effects based on its design. I will cover the biggest pain points I've experienced and what this tool aims to address:

My tools think in lists - until my tools parse exported JSON graphs, I need graph results in a line-by-line format .txt file
Copy/pasting graph results - this plays into the first but do we need to explain this one?
Graphs can be too large to draw - the information contained in any graph can aid our goals as the attacker and we need to be able to view all data efficiently
Manually running custom cyphers is time-consuming - let's automate it :)

This tool can also help blue teams to reveal detailed information about their Active Directory environments as well.

Features

Take back control of your BloodHound data with cypherhound!

264 cyphers as of date
- Set cyphers to search based on user input (user, group, and computer-specific)
- User-defined regex cyphers
User-defined exporting of all results
- Default export will be just end object to be used as target list with tools
- Raw export option available in grep/cut/awk-friendly format

Installation

Make sure to have python3 installed and run:

python3 -m pip install -r requirements.txt

Usage

Start the program with: python3 cypherhound.py -u <neo4j_username> -p <neo4j_password>

Commands

The full command menu is shown below:

Command Menu
set - used to set search parameters for cyphers, double/single quotes not required for any sub-commands
    sub-commands
        user - the user to use in user-specific cyphers (MUST include @domain.name)
        group - the group to use in group-specific cyphers (MUST include @domain.name)
        computer - the computer to use in computer-specific cyphers (SHOULD include .domain.name or @domain.name)
        regex - the regex to use in regex-specific cyphers
    example
        set user svc-test@domain.local
        set group domain admins@domain.local
        set computer dc01.domain.local
        set regex .*((?i)web).*
run - used to run cyphers
    parameters
        cypher number - the number of the cypher to run
    example
        run 7
export - used to export cypher results to txt files
    parameters
        cypher number - the number of the cypher to run and then export   
        output filename - the number of the output file, extension not needed
        raw - write raw output or just end object (optional)
    example
        export 31 results
        export 42 results2 raw
list - used to show a list of cyphers
    parameters
        list type - the type of cyphers to list (general, user, group, computer, regex, all)
    example
        list general
        list user
        list group
        list computer
        list regex
        list all
q, quit, exit - used to exit the program
clear - used to clear the terminal
help, ? - used to display this help menu

Important Notes

The program is configured to use the default Neo4j database and URI
Built for BloodHound 4.2.0, certain edges will not work for previous versions
Windows users must run pip3 install pyreadline3
Shortest paths exports are all the same (raw or not) due to their unpredictable number of nodes

Future Goals

Add cyphers for Azure edges

Issues and Support
