# targetedKerberoast



targetedKerberoast is a Python script that can, like many others (e.g. [GetUserSPNs.py](https://github.com/SecureAuthCorp/impacket/blob/master/examples/GetUserSPNs.py)), print "kerberoast" hashes for user accounts that have a SPN set. 

This tool brings the following additional feature: for each user without SPNs, it tries to set one (abuse of a write permission on the `servicePrincipalName` attribute), print the "kerberoast" hash, and delete the temporary SPN set for that operation. This is called targeted Kerberoasting.

This tool can be used against all users of a domain, or supplied in a list, or one user supplied in the CLI.

# Usage



This tool supports the following authentications

 - (NTLM) Cleartext password

 - (NTLM) [Pass-the-hash](https://www.thehacker.recipes/active-directory-domain-services/movement/lm-and-ntlm/pass-the-hash)

 - (Kerberos) Cleartext password

 - (Kerberos) [Pass-the-key](https://www.thehacker.recipes/ad/movement/kerberos/ptk) / [Overpass-the-hash](https://www.thehacker.recipes/ad/movement/kerberos/opth)

 - (Kerberos) [Pass-the-cache](https://www.thehacker.recipes/ad/movement/kerberos/ptc) (type of [Pass-the-ticket](https://www.thehacker.recipes/ad/movement/kerberos/ptt))



Among other things, targetedKerberoast supports multi-level verbosity, just append `-v`, `-vv`, ... to the command :)



```

usage: targetedKerberoast.py [-h] [-v] [-q] [-D TARGET_DOMAIN] [-U USERS_FILE] [--request-user username] [-o OUTPUT_FILE] [--use-ldaps] [--only-abuse] [--no-abuse] [--dc-ip ip address] [-d DOMAIN] [-u USER]

                             [-k] [--no-pass | -p PASSWORD | -H [LMHASH:]NTHASH | --aes-key hex key]



Queries target domain for SPNs that are running under a user account and operate targeted Kerberoasting



optional arguments:

  -h, --help            show this help message and exit

  -v, --verbose         verbosity level (-v for verbose, -vv for debug)

  -q, --quiet           show no information at all

  -D TARGET_DOMAIN, --target-domain TARGET_DOMAIN

                        Domain to query/request if different than the domain of the user. Allows for Kerberoasting across trusts.

  -U USERS_FILE, --users-file USERS_FILE

                        File with user per line to test

  --request-user username

                        Requests TGS for the SPN associated to the user specified (just the username, no domain needed)

  -o OUTPUT_FILE, --output-file OUTPUT_FILE

                        Output filename to write ciphers in JtR/hashcat format

  --use-ldaps           Use LDAPS instead of LDAP

  --only-abuse          Ignore accounts that already have an SPN and focus on targeted Kerberoasting

  --no-abuse            Don't attempt targeted Kerberoasting



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



secrets:

  -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

  --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)

```



Below is an example what the tool can do.
