This plugin will allow you to run operations on Windows hosts only.
To use this plugin, you must have a Mongo database installed and running locally. Detailed MongoDB Server installation instructions can be found here: https://docs.mongodb.com/manual/installation/#mongodb-community-edition-installation-tutorials
If installing/using this plugin offline, make sure to download the necessary dependencies:
pip download -r caldera/plugins/adversary/requirements.txt --dest /caldera/python_depsPlease note, this plugin also requires that you load the GUI plugin with it.
Operations run through the Adversary Plugin generate logs in the BRAWL Shared Format (BSF). More information about this format can be found here. Please note that CALDERA's BSF download produces an ordered collection of BSF objects (other header information, such as 'game_id' and 'bsf_version', is handled elsewhere). Excerpts from an example CALDERA generated BSF log are documented here as an example of how to read and reference the format.

]In order for Adversary Mode to move laterally through the network and successfully leverage PowerSploit tools, several security features of Windows 10 must be turned off. We have provided a simple powershell script below to disable those features; it has been tested on Windows 10 (up to 1904) and Server 2012. This script will do a couple things:
This script has been tested on limited Windows distributions (but it should work on most versions). THIS WILL DISABLE CRITICAL SECURITY FEATURES ON WINDOWS - USE AT YOUR OWN RISK.
