Реверс-инжиниринг Xiaomi Smart Band 10

У носимых устройств есть парадокс: браслет измеряет ваши пульс, сон и активность, но готового открытого API для интеграции этих данных в сторонние системы (например, домашний мониторинг или локальную БД) производитель не предоставляет. Официальное приложение Xiaomi Mi Fitness показывает красивые графики, но данные остаются «запертыми» внутри мобильной экосистемы. Изначальная задача была чисто прикладной: настроить автоматический сбор данных о здоровье в локальную SQLite-базу и выводить отчеты в семейный Telegram-бот. Поскольку браслет синхронизируется с приложением, а то в свою очередь с облаком Xiaomi, данные гарантированно передаются по сети. Нужно было понять, в каком формате они передаются и как их забрать. Эта статья - технический разбор пути от анализа сетевого трафика и настройки доверия к собственному CA до реверс-инжиниринга RC4-протокола Xiaomi, расшифровки AES/CBC-объектов из хранилища FDS и парсинга проприетарного бинарного формата сна.

It remains a difficult phenomenon to truly understand: #opensource or #digitalcommons are often kept out with great conviction, justified by claims of immature #security and unacceptable risk.

Yet that same conviction is rarely seen when consensus relies on decades-old security components that have caused harm for over 30 years.

Security, then, seems less a principle than a convenient argument used when it suits other interests.

Cryptohack. Решение Oh SNAP. Атака Флюрера-Мантина-Шамира (Fluhrer, Mantin, Shamir)

Приветствую, Хабр! В нескольких предыдущих статьях я рассматривал различные режимы шифрования для блочных шифров, постепенно сдвигаясь в сторону режимов, превращающих блочные шифры в потоковые. В новой статье в фокусе будет чисто потоковый шифр - RC4. Я расскажу о самом шифре, а также об атаке FMS и применении её для решения задачи Oh, SNAP с платформы Cryptohack.
