The next iteration of DFF’s SPTM deep dive. This post aims to broaden the discussion and fill in the full picture of SPTM.
Our goal at DFF is to reveal any threats on mobile devices, and that requires us to keep up to date with every single version of Android and iOS, including the beta and "Developer Preview" phases.
