Installation

To use Kerberos, ldeep needs to build native extensions and some headers could be required:

Debian:

sudo apt-get install -y libkrb5-dev krb5-config gcc python3-dev

ArchLinux:

sudo pacman -S krb5

Install from pypi (latest released version)

python -m pip install ldeep

Install from GitHub (current state of master branch)

python -m pip install git+https://github.com/franc-pentest/ldeep

Development

Clone the project and install the backend build system pdm:

python -m pip install pdm
git clone https://github.com/franc-pentest/ldeep && cd ldeep

Install an isolated version

Clone and install dependencies:

pdm install

Run locally:

pdm run ldeep

Install the package in your system

python -m pip install .

Build source and wheel distributions

python -m build

ldeep

Help is self-explanatory. Let's check it out:

$ ldeep -h
usage: ldeep [-h] [--version] [-o OUTFILE] [--security_desc] {ldap,cache} ...

options:
  -h, --help            show this help message and exit
  --version             show program's version number and exit
  -o OUTFILE, --outfile OUTFILE
                        Store the results in a file
  --security_desc       Enable the retrieval of security descriptors in ldeep results

Mode:
  Available modes

  {ldap,cache}          Backend engine to retrieve data

ldeep can either run against an Active Directory LDAP server or locally on saved files:

The the cache mode can be used to query some other information.

Usage with Kerberos config

For Kerberos, you will also need to configure the /etc/krb5.conf.:

[realms]
      CORP.LOCAL = {
              kdc = DC01.CORP.LOCAL
      }

Upcoming

  • Proper DNS zone enumeration
  • ADCS enumeration
  • Sites and subnets
  • Project tree
  • Useful Kerberos delegation information
  • Any ideas?
