Bagaimana Memverifikasi Keaslian APK?
Check File Size
Official APK fatcai99 v5.2.1 memiliki file size exactly 42.1 MB. Jika size berbeda (misalnya 35MB, 50MB, atau 89MB), itu adalah fake atau modified APK.
Cara check: Right-click file APK → Properties → Check "Size" field. Harus menunjukkan 44,141,568 bytes (42.1 MB).
Verify SHA-256 Checksum
Setiap official APK memiliki unique SHA-256 hash. Ini adalah digital fingerprint yang membuktikan file tidak dimodifikasi.
Official SHA-256 Hash untuk v5.2.1:
Cara verify di Windows: Install HashTab → Right-click APK → Properties → File Hashes tab → Compare SHA-256 dengan hash di atas.
Cara verify di Linux/Mac: Open Terminal → Run command:
sha256sum fatcai99_v5.2.1.apk
Scan dengan Antivirus
Official fatcai99 APK adalah 100% malware-free dan akan pass semua antivirus scans dengan 0 detections.
VirusTotal Scan Result: Upload APK ke VirusTotal.com → Official APK akan menunjukkan 0/67 detections.
Jika scan menunjukkan any detections (even 1/67), DO NOT INSTALL - it's fake atau infected.
Check Developer Certificate
Official APK signed dengan developer certificate dari Android Research Institute. Check ini setelah install.
Cara check: Settings → Apps → fatcai99 → Advanced → App Details → Certificate info → Verify "Issued to" shows "Android Research Institute".
Jika certificate shows nama lain atau unsigned, uninstall immediately - itu bukan official app.
