Alat Spyware Terkenal Ditemukan Bersembunyi Di Bawah Empat Lapisan Obfuscation

September 30, 2021 by Winnie the Pooh

FinFisher/FinSpy, spyware komersial yang terkenal dan sangat kontroversial yang dijual oleh perusahaan Jerman FinFisher ke negara-bangsa dan penegak hukum untuk tujuan pengawasan, sekarang membungkus dirinya dalam empat lapisan obfuscation dan metode penghindaran deteksi lainnya untuk menghindari penemuan dan analisis.

Para peneliti di perusahaan keamanan Kaspersky yang berbasis di Moskow membutuhkan waktu delapan bulan untuk melakukan reverse engineering dan analisis penuh untuk mengungkap versi baru spyware yang sangat tersembunyi ini untuk Windows, Mac OS, dan Linux.

Selain metode obfuscation empat lapis, spyware juga sekarang menggunakan bootkit UEFI (Unified Extensible Firmware Interface) untuk menginfeksi targetnya, dan juga mengenkripsi malware dalam memori, menurut para peneliti. Penelitian tim Kaspersky dimulai pada 2019, dan mereka akhirnya membagikan temuan mereka di KTT Analis Keamanan online Kaspersky.

Para peneliti sebelumnya telah menemukan installer berbahaya untuk TeamViewer, VLC Media Player, dan WinRAR yang tidak memiliki tautan ke malware yang diketahui. Tetapi ketika mereka menemukan situs web berbahasa Burma dengan installer yang sama, serta sampel FinFisher untuk Android, mereka berputar kembali ke installer sebelumnya dan menghubungkan titik-titik ke FinFisher/FinSpy.

Bagaimana FinSpy masuk ke mesin korban yang diteliti oleh para peneliti tidak diketahui, tetapi mungkin saja penyerang memiliki akses fisik atau mencuri kredensial administratif.

Igor Kuznetsov, peneliti keamanan utama di Tim Riset dan Analisis Global (GReAT) Kaspersky mengatakan para korban entah bagaimana mengunduh dan secara tidak sengaja menginstal malware tahap pertama.
