| Threat | Attack Vector | Mitigation |
|--------|---------------|------------|
| Data Leakage | Malicious app reads the encrypted SharedPreferences. | Keys stored in Android Keystore (hardware‑backed where available); encryption uses AES‑256 GCM. |
| Man‑in‑the‑Middle (MITM) | Intercepting API calls over Wi‑Fi. | TLS 1.3 + certificate pinning; HSTS enforced on all endpoints. |
| Replay Attacks | Re‑using old OAuth tokens. | Short‑lived access tokens (15 min) with refresh token rotation; server validates iat claim. |
| Device Tampering | Running on rooted device to extract secrets. | Play Integrity API + SafetyNet attestation; app disables private collections on compromised devices. |
| Unauthorized Media Access | Exporting cached images from /data/data/.../cache. | Cache files stored in Context.MODE_PRIVATE; encrypted at rest using per‑file keys derived from the user’s passphrase. |
| Social Engineering | Phishing login screen mimicking Jizztagram. | OAuth flow redirects to Instagram’s official login page; no credentials are ever entered inside the app. |
