TeamFiltration is a cross-platform framework for enumerating, spraying, exfiltrating, and backdooring O365 AAD accounts. See the TeamFiltration wiki page for an introduction into how TeamFiltration works and the Quick Start Guide for how to get up and running!
This tool has been used internally since January 2021 and was publicly released in my talk Taking a Dumb In The Cloud during DefCON30.
You can download the latest precompiled release for Linux, Windows and MacOS
The releases are precompiled into a single application-dependent binary. The size go up, but you do not need NET or any other dependencies to run them.
