Toolkit de relais Kerberos et d'abus de délégation non contrainte
Boîte à outils pour abuser de Kerberos. Nécessite impacket, ldap3 et dnspython pour fonctionner. Il est recommandé d'installer impacket directement depuis git pour disposer de la dernière version disponible.
Plus d'informations sur cette boîte à outils disponibles dans mon blog https://dirkjanm.io/krbrelayx-unconstrained-delegation-abuse-toolkit/. Des informations sur le relais Kerberos dans le blog de suivi https://dirkjanm.io/relaying-kerberos-over-dns-with-krbrelayx-and-mitm6/.

Outil simple pour déclencher le bug SpoolService via un backconnect RPC. Similaire à dementor.py. Merci à @agsolino pour avoir implémenté ces appels RPC.
usage: printerbug.py [-h] [-target-file file] [-port [destination port]]
[-hashes LMHASH:NTHASH] [-no-pass]
target attackerhost
positional arguments:
target [[domain/]username[:password]@]<targetName or address>
attackerhost hostname to connect to
optional arguments:
-h, --help show this help message and exit
connection:
-target-file file Use the targets in the specified file instead of the
one on the command line (you must still specify
something as target name)
-port [destination port]
Destination port to connect to SMB Server
authentication:
-hashes LMHASH:NTHASH
NTLM hashes, format is LMHASH:NTHASH
-no-pass don't ask for password (useful when proxying through
ntlmrelayx)
-k 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
-dc-ip ip address IP Address of the domain controller. If omitted it will use the domain part (FQDN) specified in the target
parameter
-target-ip ip address
IP Address of the target machine. If omitted it will use whatever was specified as target. This is useful
when target is the NetBIOS name or Kerberos name and you cannot resolve it

[-v TARGET]
Kerberos relay and unconstrained delegation abuse tool. By @_dirkjan / dirkjanm.io
Main options:
-h, --help show this help message and exit
-debug Turn DEBUG output ON
-t TARGET, --target TARGET
Target to attack, since this is Kerberos, only HOSTNAMES are valid. Example: smb://server:445 If
unspecified, will store tickets for later use.
-tf TARGETSFILE File that contains targets by hostname or full URL, one per line
-w Watch the target file for changes and update target list automatically (only valid with -tf)
-ip INTERFACE_IP, --interface-ip INTERFACE_IP

-r SMBSERVER Redirect HTTP requests to a file:// path on SMBSERVER
-l LOOTDIR, --lootdir LOOTDIR
Loot directory in which gathered loot (TGTs or dumps) will be stored (default: current directory).
-f {ccache,kirbi}, --format {ccache,kirbi}
Format to store tickets in. Valid: ccache (Impacket) or kirbi (Mimikatz format) default: ccache
-codec CODEC Sets encoding used (codec) from the target's output (default "utf-8"). If errors are detected, run
chcp.com at the target, map the result with https://docs.python.org/2.4/lib/standard-encodings.html and
then execute ntlmrelayx.py again with -codec and the corresponding codec
-no-smb2support Disable SMB2 Support
-wh WPAD_HOST, --wpad-host WPAD_HOST
Enable serving a WPAD file for Proxy Authentication attack, setting the proxy host to the one supplied.
-wa WPAD_AUTH_NUM, --wpad-auth-num WPAD_AUTH_NUM
Prompt for authentication N times for clients without MS16-077 installed before serving a WPAD file.
-6, --ipv6 Listen on both IPv6 and IPv4
Kerberos Keys (of your account with unconstrained delegation):
-p PASSWORD, --krbpass PASSWORD
Account password
-hp HEXPASSWORD, --krbhexpass HEXPASSWORD
Hex-encoded password
-s USERNAME, --krbsalt USERNAME
Case sensitive (!) salt. Used to calculate Kerberos keys.Only required if specifying password instead
of keys.
-hashes LMHASH:NTHASH
NTLM hashes, format is LMHASH:NTHASH
-aesKey hex key AES key to use for Kerberos Authentication (128 or 256 bits)
-dc-ip ip address IP Address of the domain controller. If ommited it use the domain part (FQDN) specified in the target
parameter
SMB attack options:
-e FILE File to execute on the target system. If not specified, hashes will be dumped (secretsdump.py must be
in the same directory)
-c COMMAND Command to execute on target system. If not specified, hashes will be dumped (secretsdump.py must be in
the same directory).
--enum-local-admins If relayed user is not admin, attempt SAMR lookup to see who is (only works pre Win 10 Anniversary)
LDAP attack options:
--no-dump Do not attempt to dump LDAP information
--no-da Do not attempt to add a Domain Admin
--no-acl Disable ACL attacks
--no-validate-privs Do not attempt to enumerate privileges, assume permissions are granted to escalate a user via ACL
attacks
--escalate-user ESCALATE_USER

--delegate-access Delegate access on relayed computer account to the specified account
AD CS attack options:
--adcs Enable AD CS relay attack
--template TEMPLATE AD CS template. Defaults to Machine or User whether relayed account name ends with `$`. Relaying a DC
should require specifying `DomainController`
-v TARGET, --victim TARGET
Victim username or computername$, to request the correct certificate name.
