| Threat | Mitigation | |--------|------------| | (e.g., backup file exposed) | Use EncryptedSharedPreferences for config; encrypt backup with user‑provided password; store backup in app‑specific external folder with noMedia flag. | | Brute‑force on PIN/Password | Enforce exponential back‑off after 3 failed attempts; optionally wipe local settings after 10 failures. | | Stealth mode discovery | Use a randomised launcher activity name; hide the real launcher entry in AndroidManifest with <category android:name="android.intent.category.DEFAULT" /> only. | | Unauthorized media retrieval | All media payloads are encrypted end‑to‑end; server stores only ciphertext; decryption keys derived from user session and optional per‑message secret. | | Background sync abuse | WorkManager constraints ensure sync only under allowed network conditions; respect Android’s Doze mode. | Zalo 1.0.44 Mod.apk BETTER
