We worked with @_dirkjan to get this as an exclusive into Outflank Security Tooling with a new tool called ROADtune. ROADtune allows red teamers to: - bypass CAP by faking device compliance registration - loot secrets from applications pushed to compliant devices Cool stuff!

For anyone who's badge I managed to "Pwnz0rz111" today at RedTreat, you can revert back to the "original" FW by booting the badge, and once my spooky purge face shows up, press the middle button (the up button) and then the top button (the select button). The image just overlays a hidden menu option, so you're just selecting "Unpwn Badge" in the background which switches the badge over to OTA0 (original files). Thanks to @max__grim and @c3c for the awesome badges, and to @MDSecLabs and @OutflankNL for the amazing CON!
