Varian Baru Malware Joker di Android

July 16, 2020 by Winnie the Pooh

Analis dari Check Point Research menemukan sejumlah aplikasi yang menggunakan apa yang peneliti deskripsikan sebagai varian baru dari malware Joker dan yang bersembunyi di Google Play Store dalam “aplikasi yang tampaknya sah.”

“Kami menemukan bahwa versi Joker yang diperbarui ini dapat mengunduh malware tambahan ke perangkat, yang membuat pengguna berlangganan ke layanan premium tanpa sepengetahuan atau persetujuan mereka,” tulis tim Check Point dalam ringkasan temuan mereka. Laporan itu memberikan nama paket untuk 11 aplikasi (salah satunya terdaftar dua kali), sehingga Anda dapat menggunakan ini untuk melihat apakah salah satu dari mereka mungkin ada di ponsel Anda tetapi dengan identitas yang berbeda:

com.imagecompress.android
com.contact.withme.texts
com.hmvoice.friendsms
com.relax.relaxation.androidsms
com.cheery.message.sendsms
com.cheery.message.sendsms
com.peason.lovinglovemessage
com.file.recovefiles
com.LPlocker.lockapps
com.remindme.alram
com.training.memorygame

Untuk membuat orang berlangganan ke layanan premium tanpa mereka sadari, malware Joker tampaknya menggunakan layanan Notification Listener aplikasi asli, serta file dex dinamis yang dimuat oleh server perintah dan kontrol untuk melakukan pendaftaran pengguna yang sebenarnya. Check Point mengatakan itu adalah teknik umum bagi pengembang malware PC Windows untuk mengaburkan “sidik jari” kode mereka dengan menyembunyikan file dex sambil tetap memastikannya dapat memuat.

Google telah menghapus aplikasi di atas dari Play Store, tetapi Aviran Hazum dari Check Point mengatakan kepada salah satu outlet berita bahwa malware Joker kemungkinan akan kembali lagi dalam beberapa bentuk. “Malware Joker sulit dideteksi, meskipun ada investasi Google dalam menambahkan perlindungan Play Store. Meskipun Google menghapus aplikasi jahat dari Play Store, kami sepenuhnya dapat beranggapan bahwa Joker bisa beradaptasi lagi.”
