finduncommonshares's Introduction

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.
GitHub release (latest by date) YouTube Channel Subscribers

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.
  • Export results in JSON with IP, name, comment, flags and UNC path with --export-json <file.json>.
  • Export results in XLSX with IP, name, comment, flags and UNC path with --export-xlsx <file.xlsx>.
  • Export results in SQLITE3 with IP, name, comment, flags and UNC path with --export-sqlite <file.db>.
  • Iterate on LDAP result pages to get every computer of the domain, no matter the size.

Demonstration

Quick win commands

  • List all shares where your current user has WRITE access:

    ./FindUncommonShares.py -u user -p 'Podalirius123!' -d DOMAIN --dc-ip 192.168.1.71 --writable
    
  • Export list of shares in the domain to an Excel file for the client:

    ./FindUncommonShares.py -u user -p 'Podalirius123!' -d DOMAIN --dc-ip 192.168.1.71 --export-xlsx ./examples/results.xlsx
    
  • List all shares with access rights for your current user:

    ./FindUncommonShares.py -u user -p 'Podalirius123!' -d DOMAIN --dc-ip 192.168.1.71 --check-user-access
    

Usage

$ ./FindUncommonShares.py -h
FindUncommonShares v3.0 - by @podalirius_

usage: FindUncommonShares.py [-h] [-v] [--use-ldaps] [-q] [--debug] [-no-colors] [-t THREADS] [-l LDAP_QUERY] [-ns NAMESERVER]
                             [--check-user-access] [--readable] [--writable] [-I] [-i IGNORED_SHARES] [-s ACCEPTED_SHARES]

                             address [-d DOMAIN] [-u USER] [--no-pass | -p PASSWORD | -H [LMHASH:]NTHASH | --aes-key hex key] [-k]

Find uncommon SMB shares on remote machines.

options:
  -h, --help            show this help message and exit
  -v, --verbose         Verbose mode. (default: False).
  --use-ldaps           Use LDAPS instead of LDAP.
  -q, --quiet           Show no information at all.
  --debug               Debug mode. (default: False).
  -no-colors            Disables colored output mode.
  -t THREADS, --threads THREADS
                        Number of threads (default: 20).
  -l LDAP_QUERY, --ldap-query LDAP_QUERY
                        LDAP query to use to extract computers from the domain.
  -ns NAMESERVER, --nameserver NAMESERVER
                        IP of the DNS server to use, instead of the --dc-ip.
  --check-user-access   Check if current user can access the share.
  --readable            Only list shares that current user has READ access to.
  --writable            Only list shares that current user has WRITE access to.
  -I, --ignore-hidden-shares
                        Ignores hidden shares (shares ending with $)
  -i IGNORED_SHARES, --ignore-share IGNORED_SHARES
                        Specify shares to ignore explicitly. (e.g., --ignore-share 'C$' --ignore-share 'Backup')
  -s ACCEPTED_SHARES, --show-share ACCEPTED_SHARES
                        Specify shares to show explicitly. (e.g., --show-share 'C$' --show-share 'Backup')

Output files:
  --export-xlsx EXPORT_XLSX
                        Output XLSX file to store the results in.
  --export-json EXPORT_JSON
                        Output JSON file to store the results in.
  --export-sqlite EXPORT_SQLITE
                        Output SQLITE3 file to store the results in.

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

Exported results

Each JSON entry looks like this:

{
    "computer": {
        "fqdn": "TDC01.DOMAIN.local",
        "ip": "192.168.1.71"
    },
    "share": {
        "name": "IPC$",
        "comment": "Remote IPC",
        "hidden": true,
        "uncpath": "\\\\192.168.1.71\\IPC$\\",
        "type": {
            "stype_value": 2147483651,
            "stype_flags": [
                "STYPE_IPC",
                "STYPE_TEMPORARY"
            ]
        },
        "access_rights": {
            "readable": true,
            "writable": false
        }
