Had a blast attending and presenting at @labscon_io for the second year in a row! If you are curious about BYOVD in UEFI, and how we at @binarly_io uncovered an incomplete patch for a Supermicro BMC bug, check out our talk slides below👇
Very excited for this CodeBlue talk, as the deeper insights into this bootkit will be explained with 40-min slides. Especially for Android bootkit but Windows rootkit also seems interesting as it uses many techniques that exisiting UEFI bootkits doesn't use (WOOT paper Table 1).
