Raleigh2016 / FindUncommonShares

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

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.
• 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.

  --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:
  --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

Examples :

$ ./FindUncommonShares.py -u 'user1' -d 'LAB.local' -p 'P@ssw0rd!' --dc-ip 192.168.2.1
FindUncommonShares v2.3 - 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
$

Each JSON entry looks like this:

{
    "computer": {
        "fqdn": "DC01.LAB.local",
        "ip": "192.168.1.1"
    },
    "share": {
        "name": "ADMIN$",
        "comment": "Remote Admin",
        "hidden": true,
        "uncpath": "\\\\192.168.1.46\\ADMIN$\\",
        "type": {

                "STYPE_TEMPORARY"
            ]
