In-depth ldap enumeration utility

Project description

LDEEP

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

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

optional arguments:
    -h, --help            show this help message and exit
    -o OUTFILE, --outfile OUTFILE
                      Store the results in a file
    --security_desc   Enable the retrieval of security descriptors in ldeep
                      results


Modes:
    Available modes

    {ldap,cache}          Mode to query

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

$ ldeep ldap -u Administrator -p 'password' -d winlab -s ldap://10.0.0.1 all backup/winlab

These two modes have different options:

INSTALL

ldeep is Python3 only.:

pip3 install git+https://github.com/franc-pentest/ldeep

USAGE

Listing users without verbosity:

$ ldeep ldap -u Administrator -p 'password' -d winlab.local -s ldap://10.0.0.1 users
userspn2
userspn1
gobobo
test
krbtgt
DefaultAccount
Guest
Administrator

Listing users with reversible password encryption enable and with verbosity:

$ ldeep ldap -u Administrator -p 'password' -d winlab.local -s ldap://10.0.0.1 users reversible -v

Listing GPOs:

$ ldeep -u Administrator -p 'password' -d winlab.local -s ldap://10.0.0.1 gpo
{6AC1786C-016F-11D2-945F-00C04fB984F9}: Default Domain Controllers Policy
{31B2F340-016D-11D2-945F-00C04FB984F9}: Default Domain Policy

Getting all things:

$ ldeep ldap -u Administrator -p 'password' -d winlab.local -s ldap://10.0.0.1 all /tmp/winlab.local_dump
[+] Retrieving computers output
[+] Retrieving domain_policy output

[+] Retrieving groups output
[+] Retrieving groups verbose output
[+] Retrieving ou output
[+] Retrieving pso output
[+] Retrieving trusts output
[+] Retrieving users output
[+] Retrieving users verbose output
[+] Retrieving zones output
[+] Retrieving zones verbose output

Using this last command line switch, you have persistent output in both verbose and non-verbose mode saved:

$ ls winlab.local_dump_*
winlab.local_dump_computers.lst      winlab.local_dump_groups.json  winlab.local_dump_pso.lst     winlab.local_dump_users.lst
winlab.local_dump_domain_policy.lst  winlab.local_dump_groups.lst   winlab.local_dump_trusts.lst  winlab.local_dump_zones.json
winlab.local_dump_gpo.lst            winlab.local_dump_ou.lst       winlab.local_dump_users.json  winlab.local_dump_zones.lst

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

Upcoming

  • Proper DNS zone enumeration

  • ADCS enumeration

  • Sites and subnets

  • Project tree

  • Python package

  • Useful Kerberos delegation information

  • Any ideas?
