FindUncommonShares

The script FindUncommonShares.py is a Python equivalent of PowerView's Invoke-ShareFinder.ps1 allowing to quickly find uncommon shares in vast Windows Active Directory Domains.

Features

• Only requires a low privileges domain user account.
• Automatically gets the list of all computers from the domain controller's LDAP.
• Ignore the hidden shares (ending with $) with --ignore-hidden-shares.
• Multithreaded connections to discover SMB shares.
• JSON export of the found shares, with IP, name, comment, flags and UNC path with --json <file.json>.
• XLSX export of the found shares, with IP, name, comment, flags and UNC path with --xlsx <file.xlsx>.
• Iterate on LDAP result pages to get every computer of the domain, no matter the size.

Usage

$ ./FindUncommonShares.py -h
FindUncommonShares v2.2 - by @podalirius_

usage: FindUncommonShares.py [-h] [--use-ldaps] [-q] [--debug] [-no-colors] [-I] [-t THREADS] [--xlsx XLSX] [--json JSON] --dc-ip ip address [-d DOMAIN] [-u USER] [--no-pass | -p PASSWORD | -H [LMHASH:]NTHASH | --aes-key hex key] [-k]

Find uncommon SMB shares on remote machines.

optional arguments:
  -h, --help            show this help message and exit
  --use-ldaps           Use LDAPS instead of LDAP
  -q, --quiet           Show no information at all.
  --debug               Debug mode.
  -no-colors            Disables colored output mode
  -I, --ignore-hidden-shares
                        Ignores hidden shares (shares ending with $)
  -t THREADS, --threads THREADS
                        Number of threads (default: 20)

Output files:
  --xlsx XLSX           Output file to store the results in. (default: shares.xlsx)
  --json JSON           Output file to store the results in. (default: shares.json)

Authentication & connection:
  --dc-ip ip address    IP Address of the domain controller or KDC (Key Distribution Center) for Kerberos. If omitted it will use the domain part (FQDN) specified in the identity parameter
  -d DOMAIN, --domain DOMAIN
                        (FQDN) domain to authenticate to
  -u USER, --user USER  user to authenticate with

Credentials:
  --no-pass             Don't ask for password (useful for -k)
  -p PASSWORD, --password PASSWORD
                        Password to authenticate with
  -H [LMHASH:]NTHASH, --hashes [LMHASH:]NTHASH
                        NT/LM hashes, format is LMhash:NThash
  --aes-key hex key     AES key to use for Kerberos Authentication (128 or 256 bits)
  -k, --kerberos        Use Kerberos authentication. Grabs credentials from .ccache file (KRB5CCNAME) based on target parameters. If valid credentials cannot be found, it will use the ones specified in the command line

Examples :

$ ./FindUncommonShares.py -u 'Administrator' -d 'LAB.local' -p 'Admin123!' --dc-ip 192.168.2.1
FindUncommonShares v2.2 - by @podalirius_

[>] Extracting all computers ...
[+] Found 2 computers.

[>] Enumerating shares ...
[>] Found 'Users' on 'DC01.LAB.local'
[>] Found 'WeirdShare' on 'DC01.LAB.local' (comment: 'Test comment')
[>] Found 'AnotherShare' on 'PC01.LAB.local'
[>] Found 'Users' on 'PC01.LAB.local
$

Results are exported in JSON entries:

{"share": "Users", "uncpath": "\\\\192.168.2.1\\Users\\", "computer": "DC01.LAB.local", "comment": "", "type": {"stype_value": 0, "stype_flags": ["STYPE_DISKTREE", "STYPE_SPECIAL", "STYPE_TEMPORARY"]}}
{"share": "WeirdShare", "uncpath": "\\\\192.168.2.1\\WeirdShare\\", "computer": "DC01.LAB.local", "comment": "Test comment", "type": {"stype_value": 0, "stype_flags": ["STYPE_DISKTREE", "STYPE_SPECIAL", "STYPE_TEMPORARY"]}}
{"share": "AnotherShare", "uncpath": "\\\\192.168.2.11\\AnotherShare\\", "computer": "PC01.LAB.local", "comment": "", "type": {"stype_value": 0, "stype_flags": ["STYPE_DISKTREE", "STYPE_SPECIAL", "STYPE_TEMPORARY"]}}
{"share": "Users", "uncpath": "\\\\192.168.2.11\\Users\\", "computer": "PC01.LAB.local", "comment": "", "type": {"stype_value": 0, "stype_flags": ["STYPE_DISKTREE", "STYPE_SPECIAL", "STYPE_TEMPORARY"]}}

Each JSON entry looks like this:

{
  "share": "AnotherShare",
  "uncpath": "\\\\192.168.2.11\\AnotherShare\\",
  "computer": "PC01.LAB.local",
  "comment": "",
  "type": {
    "stype_value": 0,
    "stype_flags": [
      "STYPE_DISKTREE",
      "STYPE_SPECIAL",
      "STYPE_TEMPORARY"
    ]
  }
