Rosbank68 Banker (provisional)

Rosbank68 Banker (provisional) is a Russian-targeted Android bank trojan (final payload package ru.rosbank68.official, impersonating Rosbank) delivered behind a four-layer custom packer: an InMemoryDexClassLoader stub → AES-128-GCM asset (HKDF-derived key) → AES-128-CBC inner APK → a second AES-128-GCM layer → the banker dex, all statically recoverable. The banker reads content://sms, registers the device and receives commands over OkHttp against a C2 base URL stored in a string resource; endpoints: /api/v2/register, /api/v2/sms, /api/v2/cmd/, /api/v2/notify, /api/v2/ping, /api/v2/alert, /api/v2/broadcast-response, /api/cfg/. Permissions include READ/RECEIVE/SEND_SMS, READ_CONTACTS, READ_PHONE_STATE/NUMBERS and CALL_PHONE.
