pyldapsearch 0.2.0

Tool for issuing manual LDAP queries which offers bofhound compatible output

pyldapsearch

This is designed to be a python "port" of the ldapsearch BOF by TrustedSec, which is a part of this repo.

pyldapsearch allows you to execute LDAP queries from Linux in a fashion similar to that of the aforementioned BOF. Its output format closely mimics that of the BOF and all query output will automatically be logged to the user's home directory in .pyldapsearch/logs, which can ingested by bofhound.

Why would I ever use this?

Great question. pyldapsearch was built for a scenario where the operator is utilizing Linux and is attempting to issue LDAP queries while flying under the radar (BloodHound will be too loud, expensive LDAP queries are alerted on, etc). When pyldapsearch is combined with bofhound, you can still obtain BloodHound compatible data that allows for AD visualization and identification of ACL-based attack paths, which are otherwise difficult to identify through manually querying LDAP.

Outside of usage during detection-conscious and bofhound-related situations, pyldapsearch can be useful for issuing targeted, one-off LDAP queries during generic engagements.

Installation

Use uv

curl -LsSf https://astral.sh/uv/install.sh | sh

# Install pyldapsearch 
git clone https://github.com/Tw1sm/pyldapserach
cd pyldapserach
uv sync
uv run pyldapserach --help

Examples

Query all the data - if you intend to do this, just run BloodHound :)

pyldapsearch ez.lab/administrator:pass '(objectClass=*)'

Query only the name, memberOf and ObjectSID of the user matt

pyldapsearch ez.lab/administrator:pass '(sAMAccountName=matt)' -attributes name,memberof,objectsid

Query all attributes for all user objects, but only return 3 results

pyldapsearch ez.lab/administrator:pass '(objectClass=user)' -limit 3

Query all attributes of the user matt, specifying the IP of the DC to query

pyldapsearch ez.lab/administrator:pass '(&(objectClass=user)(name=matt))' -dc-ip 10.4.2.20

Query all objects, specifying the search base to use

pyldapsearch ez.lab/administrator:pass '(objectClass=*)' -base-dn 'CN=Users,DC=EZ,DC=LAB'

Execute a query without displaying query results to the console (results will still be logged)

pyldapsearch ez.lab/administrator:pass '(objectClass=*)' -silent

Perform a query using an anonymous bind

pyldapsearch 'ez.lab'/'':'' '(objectClass=*)'

Perform a query across a domain trust

pyldapsearch ez.lab/administrator:pass '(objectClass=*)' -base-dn 'DC=otherdomain,DC=local' -dc-ip 10.1.4.20
