Piotr Esden-TempskiHey everyone! The second Black Magic Debug V2.0.0-rc2 Firmware major stable release candidate is out! We have addressed a bunch of issues in the previous release candidate! Please give this release a try and report any issues you may find! See release notes for details for this release.

HabrGigaVulnerability: обход механизмов защиты микроконтроллеров GigaDevice GD32При разработке аппаратных решений на базе микроконтроллеров производители хотят защитить свою прошивку от попадания в руки злоумышленников, так как в ней могут содержаться чувствительная информация, ключи шифрования, уникальные алгоритмы, представляющие ценность, и др. Для этого в большинстве микроконтроллеров реализованы технологии защиты от считывания (readout protection) встроенной флеш-памяти. Но так ли хорошо они защищают? К сожалению, не все технологии Readout Protection работают так, как задумывалось. Для обхода защиты могут быть использованы уязвимости отладочных интерфейсов, нетривиальные атаки типа fault-injection и даже инвазивное вмешательство. Мы в Positive Labs занимаемся исследованиями безопасности различного «железа». Поэтому, когда в наши руки попало устройство на базе микроконтроллера семейства GD32 компании GigaDevice, мы сами не заметили, как начали исследовать применяющиеся в этих микроконтроллерах технологии защиты. Данные микроконтроллеры довольно популярны и используются повсеместно, в том числе в качестве замены микроконтроллеров STM32, т.к. зачастую совместимы с ними по выводам и даже по карте адресного пространства. Исследование оказалось довольно увлекательным, а результаты — впечатляющими!
