In August 2022, I gave my presentation "Taking a dump in the cloud" at the world's largest security conference, DEF CON, in Las Vegas. The presentation was an introduction to the tool TeamFiltration, which was publicly launched on the same day. TeamFiltration is an open-source framework for attacking Microsoft O365 environments. In this presentation, we talked about typical attack flows using the tool, tips, tricks, and hidden undocumented features built into TeamFiltration. The presentation built on what was presented in Vegas but took it several steps further. If you own and/or regularly perform attacks against Microsoft O365, this is a presentation you definitely don't want to miss.
