Otoritas AS dan Bulgaria mengganggu operasi ransomware NetWalker

January 28, 2021 by Winnie the Pooh

Badan penegak hukum dari Bulgaria dan AS telah mengganggu infrastruktur NetWalker minggu ini, salah satu geng ransomware paling aktif tahun 2020.

Pejabat Bulgaria menyita server yang digunakan untuk menghosting portal web gelap untuk geng NetWalker, sementara pejabat di AS menuntut seorang warga negara Kanada yang diduga menghasilkan setidaknya $ 27,6 juta dari perusahaan yang menginfeksi dengan ransomware NetWalker.

Server yang disita digunakan untuk menghosting halaman tempat korban serangan NetWalker diarahkan untuk berkomunikasi dengan penyerang dan menegosiasikan tuntutan tebusan.

Server yang sama juga menjadi tuan rumah bagian blog tempat geng NetWalker membocorkan data yang mereka curi dari perusahaan yang diretas, dan yang menolak untuk membayar permintaan tebusan – sebagai bentuk balas dendam dan mempermalukan publik.

Rincian tentang warga negara Kanada yang didakwa hari ini belum tersedia selain nama dan tempat tinggalnya – Sebastien Vachon-Desjardins, dari Gatineau.

Vachon-Desjardins saat ini diyakini sebagai “afiliasi”, seseorang yang menyewa kode ransomware dari pencipta NetWalker.

Jenis bisnis ini disebut Ransomware-as-a-Service, atau RaaS, dan merupakan pengaturan umum yang digunakan oleh banyak geng ransomware saat ini.

Sebelum penghapusan hari ini, NetWalker beroperasi melalui topik yang diposting di beberapa forum bawah tanah oleh pengguna bernama Bugatti. Pengguna ini mengiklankan fitur ransomware dan mencari “mitra” (alias afiliasi) yang akan melanggar jaringan perusahaan, mencuri data untuk digunakan sebagai pengungkit selama negosiasi, dan menginstal ransomware untuk mengenkripsi file.

Jika korban membayar, Bugatti dan afiliasinya akan membagi pembayaran tebusan sesuai dengan perjanjian yang telah dinegosiasikan sebelumnya.

Menurut otoritas AS, NetWalker telah memengaruhi setidaknya 305 korban dari 27 negara berbeda, termasuk 203 di AS.
