A CLI tool to interact with the BloodHound CE API.
BloodHound by SpecterOps is the tool to work with Active Directory attack paths, taking advantage of modeling security-relevant relationships in a graph with nodes and edges.
Once filled with data, the BloodHound database is also a great source of information useful beyond the BloodHound GUI.
A lot of information you typically dump from LDAP is already available in BloodHound.
bhcli makes this information accessible on the commandline.
Retrieve lists of user names for further processing, grep in the description field, or even run custom Cypher queries.
bhcli can also mark a bunch of objects as owned, import/export your custom queries and might perform an audit to search for interesting permissions.
Check the help message below for all features.
This tool is not published on PyPi yet, but as with any Python tool, just fetch the repository and install it.
For example using a virtualenv and pip:
$ git clone https://github.com/exploide/bloodhound-cli.git
$ cd bloodhound-cli
$ python3 -m venv venv
$ source venv/bin/activate
$ pip install .Or using pipx which handles the virtualenv automatically:
$ git clone https://github.com/exploide/bloodhound-cli.git
$ cd bloodhound-cli
$ pipx install .Thanks to the Click framework, you can get tab completion for the bhcli command for free.
At least if your shell is bash, zsh or fish.
See the click documentation if you want to enable this feature.

APPSRV02.CONTOSO.COMThe mark subcommand allows to mark a bunch of user and computer objects as belonging to an asset group.
BloodHound comes with the asset groups owned and admin_tier_0 by default, but custom groups can be created, too.
$ bhcli mark owned --file successful_password_spraying.txt
INFO: Marked 6 objects as owned.The queries subcommand allows to import and export custom Cypher queries.
The import file must either be in the format that the --save option produces or in the legacy Bloodhound's customqueries.json format.
Note that not everything from the latter might be compatible.
$ bhcli queries my-bloodhound-queries.json
INFO: Imported 12 custom queries.The cypher subcommand lets you directly run a Cypher query against the database.
It outputs JSON data which can be further processed, e.g. with jq.
$ bhcli cypher 'MATCH (c:Computer) RETURN c' | jq -c '.nodes[].properties | [.name, .haslaps]'
["WEB06.DEV.CONTOSO.COM",true]
["DC02.DEV.CONTOSO.COM",false]
