PoshC2 is written in Python3 and developed and tested on Kali Linux. For this reason, it is recommended to run PoshC2 on Kali Linux to achieve the most stable results. Alternatively, Docker images are provided which allow PoshC2 to be run on any host that supports Docker.

If you are using a host Anti-Virus it is recommended that you add an exclusion on the folder or location of the PoshC2 install and its project directory.

An install script is provided for installing PoshC2:

*** PoshC2 Install script ***
./ -b <git branch> -p <Directory to clone PoshC2 to>

Defaults are master branch to /opt/PoshC2

Elevated privileges are required as the install script performs apt updates and installations.

A bash one-liner is provided which curls down this script and executes it:

curl -sSL | sudo bash

Alternatively the repository can be cloned down and the install script manually run.

sudo ./

You can manually set the PoshC2 installation directory by passing it to the script as the -p argument. The default is /opt/PoshC2:

curl -sSL | sudo bash -s -- -p /root/PoshC2

Cutting Edge Features

We want to keep the master branch stable to ensure that users are able to rely on it when required and for this reason changes can often be feature-complete but not yet present on master as they have not been tested completely and signed-off yet.

If you want to look at upcoming features in PoshC2 you can check out the dev branch, or any individual feature branches branched off of dev.

As features are tested before they are merged into dev this branch should still be fairly stable and operators can opt in to using this branch or a particular feature branch for their engagement. This does trade stablity for new features however so do it at your own discretion.

To use dev or a feature branch pass the branch name to the script as the -b argument:

curl -sSL | sudo bash -s -- -b dev

Note the URL includes the branch name also (here dev instead of master).


You can also run PoshC2 using Docker, this allows more stable and running and enables PoshC2 to easily run on other operating systems.

The Docker install does not clone PoshC2 as the PoshC2 images on Docker Hub are used, so only a minimal install of some dependencies and scripts are performed.

To start with, install Docker on the host and then add the PoshC2 projects directory to Docker as a shared directory if required for your OS. By default this is /var/poshc2 on *nix.

Linux based hosts

For *nix hosts, an install script is provided:

*** PoshC2 Install script for Docker ***
./ -b <git branch>

Default is the master branch

Elevated privileges are required as the install script performs script installations.

curl -sSL | sudo bash

To use the dev or feature branches with Docker curl down the on the appropriate branch and pass the branch name as an argument:

curl -sSL | sudo bash -s -- -b BRANCHNAME
