Banking Trojan Cerberus Disebar Melalui Google Play

July 8, 2020 by Winnie the Pooh

Aplikasi Android berbahaya telah ditemukan di toko aplikasi Google Play yang mendistribusikan trojan perbankan, Cerberus. Aplikasi ini telah memiliki 10.000 unduhan.

Peneliti keamanan mengatakan bahwa trojan ini disebar melalui aplikasi konverter mata uang Spanyol bernama “Calculadora de Moneda”, yang telah tersedia untuk pengguna Android di Spanyol sejak Maret. Setelah dieksekusi, malware memiliki kemampuan untuk mencuri kredensial rekening bank korban dan memotong langkah-langkah keamanan, termasuk otentikasi dua faktor (2FA).

Ondrej David, Peneliti keamanan Avast, mengatakan dalam analisis nya “Yang tidak umum adalah trojan perbankan berhasil menyelinap ke Google Play Store.”

Pada beberapa minggu pertama saat tersedia di Google Play, Aplikasi ini bertindak secara normal sebagai konverter yang sah dan tidak mencuri data apa pun atau menyebabkan kerusakan apa pun. Pada pertengahan Juni, versi yang lebih baru dari konverter mata uang dirilis termasuk apa yang oleh peneliti keamanan disebut sebagai “kode dropper,” tetapi masih belum diaktifkan. Kemudian, pada 1 Juli, aplikasi melakukan tahap kedua di mana ia menjadi dropper.

Cerberus memiliki berbagai macam fungsi mata-mata dan pencurian kredensial. Trojan ini dapat duduk di atas aplikasi perbankan yang ada dan menunggu pengguna untuk login ke rekening bank mereka. Kemudian, trojan membuat lapisan baru di layar login korban, dan mencuri kredensial perbankan mereka. Selain itu, trojan memiliki kemampuan untuk mengakses pesan teks korban, artinya trojan dapat melihat kode otentikasi dua faktor (2FA) yang dikirim melalui pesan.

Para peneliti mengatakan bahwa server C2 dan muatan yang terkait dengan kampanye itu aktif hingga Senin pekan ini. Kemudian, pada Senin malam, server C2 menghilang dan konverter mata uang di Google Play tidak lagi berisi malware trojan.

David mengatakan bahwa pengguna Android dapat melindungi diri mereka sendiri dengan memperhatikan izin yang diminta aplikasi dan memeriksa peringkat pengguna suatu aplikasi. “Jika Anda merasa bahwa aplikasi tersebut meminta lebih dari yang dijanjikan, tandai ini sebagai red flags,” katanya.
