| Observation | Evidence | |-------------|----------| | | Wireshark capture shows HTTPS POST to https://ads.trkserver.net/collect every 5 min, payload: "uid":"<hashed‑android‑id>", "imei":"<masked>", "loc":"lat":..., "lon":..., "app_version":"1.2.3-repack" . | | Remote code execution | After the first beacon, the app downloads payload.dex (≈ 250 KB). The dex contains a class com.ygd.malicious.CommandExecutor with a method run(String cmd) . The app invokes it with a command string received from the C2 ( "cmd":"rm -rf /data/data/com.ygd.carbluetooth/*" ). | | Ad overlay display | At app launch, a full‑screen WebView appears for 3 seconds, showing an HTML banner from https://ads.trkserver.net/banner?id=<uid> . The overlay can be dismissed via the close button, but the app logs each dismissal. | | Audio injection | While streaming music from the phone to the car’s Bluetooth audio, a short 2‑second “sponsored jingle” is mixed into the audio stream (verified by listening to the car’s speaker). | | System‑alert usage | The overlay is drawn using the SYSTEM_ALERT_WINDOW permission, which places the ad above all other UI – a typical ad‑injector technique. | | Anti‑debug / anti‑emulation | Calls android.os.Build.FINGERPRINT.contains("generic") and Runtime.getRuntime().exec("ps | grep frida") . If any check fails, the app terminates with System.exit(0) . |
