Ransomware Ragnar Locker Menyebar Sebagai Mesin Virtual Untuk Menghindari Deteksi Keamanan

May 26, 2020 by Winnie the Pooh

Metode serangan ransomware baru membawa penghindaran pertahanan (defense evasion) ke tingkat baru — disebarkan sebagai mesin virtual penuh pada setiap perangkat yang ditargetkan untuk menyembunyikan ransomware dari pandangan.

Dalam serangan yang baru-baru ini terdeteksi, ransomware Ragnar Locker dikerahkan di dalam mesin virtual Oracle VirtualBox Windows XP. Payload serangan adalah sebuah installer 122 MB dengan 282 MB image virtual di dalamnya — semua untuk menyembunyikan ransomware 49 kB yang dapat dieksekusi.

Aktor di belakang Ragnar Locker diketahui mencuri data dari jaringan yang ditargetkan sebelum meluncurkan ransomware, untuk memberi ancaman agar korban membayar.

Pada bulan April, para aktor di belakang Ragnar Locker menyerang jaringan Energias de Portugal (EDP) dan mengklaim telah mencuri 10 terabyte data perusahaan yang sensitif, menuntut pembayaran 1.580 Bitcoin (sekitar $ 11 juta AS) dan mengancam akan merilis data jika tebusan tidak dibayarkan.
