usage: FindUncommonShares.py [-h] [-ts] [--use-ldaps] [-q] [-debug] [-t THREADS] [-o OUTPUT_FILE] --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
  -ts                   Adds timestamp to every logging output

  -debug                Debug mode
  -t THREADS, --threads THREADS
                        Number of threads (default: 5)
  -o OUTPUT_FILE, --output-file OUTPUT_FILE
                        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

  --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

Results are exported in JSON entries:

{"sharename": "Users", "uncpath": "\\\\192.168.2.1\\Users\\", "computer": "DC01.LAB.local", "comment": "", "type": {"stype_value": 0, "stype_flags": ["STYPE_DISKTREE", "STYPE_SPECIAL", "STYPE_TEMPORARY"]}}
{"sharename": "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"]}}
