Trojan perbankan SharkBot ditemukan di aplikasi antivirus Play Store

March 7, 2022 by Winnie the Pooh

Trojan perbankan akses jarak jauh, SharkBot, pertama kali terlihat pada Oktober 2021. Peneliti keamanan di Cleafy menemukannya dan menyimpulkan bahwa itu adalah satu-satunya, tanpa koneksi ke malware seperti TeaBot atau Xenomorph — dan memiliki beberapa fungsi yang sangat canggih dan berbahaya.

Satu, Sistem Transfer Otomatis (ATS), adalah fungsi baru di Android dan memungkinkan penyerang memindahkan uang secara otomatis dari rekening korban, tanpa perlu campur tangan manusia. Dan seperti yang ditemukan oleh peneliti keamanan TI Inggris, SharkBot yang diperbarui bersembunyi di dalam aplikasi antivirus yang tampak tidak bersalah yang masih tersedia di Google Play Store pada hari Sabtu.

Para peneliti dari NCC Group menerbitkan laporan awal pekan ini yang merinci cara kerja SharkBot dan bagaimana akhirnya melewati langkah-langkah keamanan Play Store.

Aplikasi berbahaya ini berfungsi seperti pil racun tiga lapis, dengan satu lapisan menyamar sebagai antivirus dan lapisan kedua sebagai versi SharkBot yang diperkecil yang kemudian diperbarui dengan mengunduh versi malware yang sepenuhnya berbahaya. Saat itulah ia bekerja menggunakan berbagai taktik untuk menjarah rekening bank korban.

Menurut NCC, SharkBot dapat melakukan “serangan overlay” saat mendeteksi aplikasi perbankan yang aktif. SharkBot memunculkan layar yang terlihat seperti bank yang dimaksud, bersiap untuk mendapatkan kredensial login yang Anda berikan. Malware ini bahkan dapat membajak notifikasi yang masuk dan mengirimkan pesan yang berasal dari perintah dan kontrol penyerang. Pada akhirnya, SharkBot dapat menggunakan metode ini untuk mengambil alih smartphone Android sepenuhnya.

Untungnya, aplikasi berbahaya ini belum menyebar lebih dari 1.000 unduhan — sejauh ini. Namun, jika Anda telah mengunduh “Antivirus, Super Cleaner” palsu dari Play Store, segera hapus dan pertimbangkan kemungkinan Anda perlu mereset ponsel Anda sepenuhnya.
