Известный ИБ-эксперт и сотрудник компании Emsisoft Фабиан Восар (Fabian Wosar) давно планировал заняться взломом малвари в прямом эфире. Читатели и коллеги Восара убедили его, что стрим, демонстрирующий реверс вредоноса – это интересно, и удобный случай вскоре представился. 16 февраля 2017 года специалист GData Картен Хан (Karsten Hahn) обнаружил нового шифровальщика Hermes, и Восар решил, что изучение малвари в прямом эфире станет хорошей темой для первого стрима.
Как выяснилось в процессе реверса, Hermes был несложен, более того, Восар сумел найти способ взлома шифрования вымогателя. Хотя декриптер еще не готов, зрители смогли наблюдать не только процесс анализа малвари, но и ее взлом. Полную версию записи стрима можно увидеть ниже.
Оказалось, что для обхода UAC (User Account Control) Hermes использует Eleven (Elevation by environment variable expansion). Фактически это позволяет файлу Shade.vbs обойти UAC и запуститься с повышенными привилегиями. После данный VBS-файл запустит файл Shade.bat, который избавится от всех теневых копий и бэкапов жертвы. Для этого шифровальщик прицельно ищет файлы .VHD, .bac, .bak, .wbcat, .bkf, Backup*.*, backup*.*, .set, .win, .dsk и удаляет их.
Проникнув на компьютер, Hermes копирует себя в C:\Users\Public\Reload.exe и выполняется. После этого запускается system_.bat, предназначенный для удаления оригинального загрузчика. Затем Hermes приступает к шифрованию пользовательской информации, используя алгоритм AES. Стоит отметить, что вредонос не изменят расширения файлов, как делают многие вымогатели, но добавляет маркер HERMES в конец каждого зашифрованного файла, как видно на скриншоте ниже.

If certifying users is a hush hush affair, Facebook’s temporary month long ban on users sending friend requests or messages to those it considers ‘strangers’ leaves many unanswered questions. The logic that an unconfirmed friend request or one sent to a user with nil or very few mutual friends, implies it was sent to a stranger, is flawed. What if the ‘befriended’ user is a new comer to Facebook and has no mutual friends? Or, if the user is inactive and does not see and therefore doesn’t confirm a friend request? What is the time frame within which a friend request must be accepted before Facebook jumps to the conclusion that it was sent to a stranger? Why can’t such information be put out in the public domain?. ray ban sunglasses
