FBI mengirimkan peringatan pertamanya tentang ‘afiliasi ransomware’

August 24, 2021 by Winnie the Pooh

Biro Investigasi Federal AS hari ini telah menerbitkan nasihat publik pertamanya yang merinci modus operandi “afiliasi ransomware.”

Istilah yang relatif baru, afiliasi ransomware mengacu pada orang atau kelompok yang menyewa akses ke platform Ransomware-as-a-Service (RaaS), mengatur intrusi ke dalam jaringan perusahaan, mengenkripsi file dengan “ransomware sewaan”, dan kemudian mendapatkan komisi dari pemerasan yang berhasil.

Dengan nama OnePercent Group, FBI mengatakan hari ini aktor ancaman ini telah aktif setidaknya sejak November 2020.

Menurut laporan FBI, secara historis, kelompok tersebut terutama mengandalkan taktik berikut untuk serangannya:

  • Menggunakan kampanye email phishing untuk menginfeksi korban dengan trojan IcedID.
  • Menggunakan trojan IcedID untuk menyebarkan muatan tambahan pada jaringan yang terinfeksi.
  • Menggunakan penetration testing framework Cobalt Strike untuk bergerak secara lateral melintasi jaringan korban.
  • Menggunakan RClone untuk mengekstrak data sensitif dari server korban.
  • Data terenkripsi dan meminta tebusan.
  • Menelepon atau mengirim email kepada korban untuk mengancam akan menjual data curian mereka di web gelap jika mereka tidak membayar tepat waktu.

Meskipun FBI tidak secara spesifik menyebut grup tersebut sebagai afiliasi ransomware, sumber di industri keamanan siber mengatakan kepada The Record bahwa OnePercent telah lama berkolaborasi dengan pencipta dan operator ransomware REvil (Sodinokibi) dan juga bekerja dengan operasi Maze dan Egregor.
