wmiexec-RegOut - Modify Version Of Impacket Wmiexec.Py, Get Output(Data,Response) From Registry, Don'T Need SMB Connection, Also Bypassing Antivirus-Software In Lateral Movement Like WMIHACKER

Modify version of impacket wmiexec.py,wmipersist.py. Got output(data,response) from registry, don't need SMB connection, but I'm in the bad code :(

Specially Thanks to:

@rootclay, wechat: _xiangshan

Overview

In original wmiexec.py, it get response from smb connection (port 445,139). Unfortunately, some antivirus software are monitoring these ports as high risk.
In this case, I drop smb connection function and use others method to execute command.

wmiexec-reg-sch-UnderNT6-wip.py: Executed command by using win32-scheduledjob class. According to xiangshan, win32-scheduledjob class only works under windows NT6 (windows-server 2003).
BTW, win32_scheduledjob has been disabled by default after windows NT6. Here is the way how to enable it.

wmipersist-wip.py (Highly recommend, !!!only works on impacket v0.9.24!!!): A Python version of WMIHACKER, which I picked the vbs template from it. Attacker can use it to do lateral movement safety under antivirus-software running.

wmiexec-regOut.py: Just a simple Win32_Process.create method example .

How it works?

wmiexec-wip.py workflow:

Step 1:

WMIC authenticated remotly

Step 2:

Use win32process class and call create method to execute command. Then, write down the result into C:\windows\temp directory named [uuid].txt

Step 3:

Encode the file content to base64 strings (need to wait a few seconds)

Step 4:

Add the converted base64 string into registry, and key name call [uuid]

Step 5:

Get the base64 strings remotly and decode it locally.

wmipersist-wip.py workflow:

Step 1:

Add custom vbs script into ActiveScriptEventConsumer class.

Step 2:

Creating an Event Filter.

Step 3:

Trigger FilterToConsumerBinding class to PWNED!

Requirements

Generally, you just need to install official impacket.

Portal

Usage

wmiexec-wip.py usage:

With cleartext password

With NTLM hashes

wmipersist-wip.py usage (Default is no output):

With cleartext password (without output)

With NTLM hashes

With output

Under Huorong antivirus-software (Using WMIHACKER VBS template!!!)

Cheatsheet

Do not forget to clean up temp directory after run command with out put.
Command: del /q /f /s C:\windows\temp\*

Command include double quotes.
Make double quotes inside single quotes wevtutil cl '"security"'

Todo

Optimize code (In bad code now.) Add more functions
