Malware Android Firestarter Menyalahgunakan Google Firebase Cloud Messaging

November 2, 2020 by Winnie the Pooh

Grup APT memulai serangan dengan loader malware Android baru, yang menggunakan layanan perpesanan Google yang sah untuk melewati deteksi.

Malware, yang dijuluki “Firestarter”, digunakan oleh grup ancaman APT yang disebut “DoNot”. DoNot menggunakan Firebase Cloud Messaging (FCM), yang merupakan solusi cloud lintas platform untuk pesan dan notifikasi untuk aplikasi Android, iOS, dan web. Layanan ini disediakan oleh Firebase, anak perusahaan Google, dan sebelumnya juga telah dimanfaatkan oleh penjahat siber.

Dalam hal ini, loader menggunakannya sebagai mekanisme komunikasi untuk terhubung dengan server perintah-dan-kontrol (C2) DoNot, membantu aktivitas grup menghindari deteksi.

“Penelitian kami mengungkapkan bahwa DoNot telah bereksperimen dengan teknik baru untuk menjaga pijakan pada mesin korban mereka,” menurut peneliti dengan Cisco Talos dalam analisis hari Kamis. “Eksperimen ini, yang dibuktikan dengan loader Firestarter, adalah tanda betapa bertekadnya mereka untuk tetap menjalankan operasi meskipun terekspos, yang menjadikan mereka aktor yang sangat berbahaya yang beroperasi di area spionase.”

Tim DoNot terus berfokus pada India dan Pakistan, dan dikenal karena menargetkan pejabat pemerintah Pakistan dan organisasi nirlaba Kashmir (Kashmir adalah kelompok etnis Dardik yang berasal dari Lembah Kashmir yang disengketakan).

Pengguna dibujuk untuk memasang aplikasi berbahaya di perangkat seluler mereka, kemungkinan dilakukan melalui pesan langsung yang memanfaatkan rekayasa sosial, kata peneliti. Nama file aplikasi Android ini (kashmir_sample.apk atau Kashmir_Voice_v4.8.apk) menunjukkan minat yang berkelanjutan di India, Pakistan, dan krisis Kashmir.
