FBI Rilis Master Key Ransomware GandCrab

Washington D.C., becabuilt.technology – Biro investigasi federal (FBI) Amerika Serikat secara resmi merilis master key ransomware GandCrab pada 15 Juli lalu. Berdasarkan master kunci dekripsi ini, siapapun bisa merilis decryptor GandCrab. Dokumen rilis FBI bisa diakses di https://www.documentcloud.org/documents/6199678-GandCrab-Master-Decryption-Keys-FLASH.html.
Pengungkapan master key ini terkait dengan kerjasama para penegak hukum di Eropa (Europol), FBI, dan Bitdefender merilis decryptor GandCrab pada pertengahan Juli lalu. Diduga, Bitdefender mendapatkan kunci tersebut setelah berhasil mengakses server command and control (C&C) GandCrab. Keberadaan kunci decryptor ini membuat kisah “sukses” GandCrab berakhir. Dan pembuatnya mengumumkan pensiun pada 31 Juni dan mengaku telah mengumpulkan uang pensiun senilai $2 miliar (hampir Rp 30 triliun).
GandCrab beroperasi dengan model bisnis ransomware-as-a-service (RaaS). Pembuatnya menjual hak mendistribusikan malware tersebut ke pihak lain dengan pembagian pendapatan 40% dari uang tebusan. Ransomware ini diketahui mulai beraksi pada Januari 2018 di Korea Selatan dan kemudian menyebar dengan cepat secara global, termasuk di Indonesia. Sampai medio 2018, GandCrab diperkirakan menguasai 50% pasar ransomware. Jumlah korbannya mencapai 500.000 orang dan menyebabkan kerugian melebihi $300 juta.
Berikut ini master key GandCrab. Analisis algoritma enkripsi malware ini bisa dibaca di: https://www.fortinet.com/blog/threat-research/gandcrab-v4-0-analysis–new-shell–same-old-menace.html
