Versi Ransomware Zeoticus 2.0 yang baru menjalankan muatan tanpa konektivitas atau perintah jarak jauh

February 8, 2021 by Winnie the Pooh

Rilis versi yang lebih fleksibel dan efektif dari ransomware Zeoticus telah menggarisbawahi semakin pentingnya pencegahan serangan, seorang peneliti keamanan menyimpulkan.

Tidak seperti pendahulunya, Zeoticus 2.0 dapat mengeksekusi muatan tanpa konektivitas atau perintah jarak jauh, menurut analisis malware yang dilakukan oleh SentinelOne.

Jenis ransomware, yang pertama kali muncul pada awal 2020, “akan dijalankan sepenuhnya secara offline, tanpa ketergantungan pada C2 (Command & Control)”, tulis Jim Walter, peneliti ancaman senior di vendor keamanan siber, dalam sebuah posting blog.

Sebagian besar peningkatan Zeoticus 2.0 “berfokus pada kecepatan dan efisiensi”, seperti penggunaan algoritme enkripsi cepat, yang mencakup algoritme XChaCha20 simetris dan, di sisi asimetris, Poly1305, XSalsa20, dan Curve25519.

Kumpulan dan permukaan serangan yang dapat dieksploitasi dari target potensial telah meluas juga, dengan malware sekarang dapat menemukan dan menginfeksi drive jarak jauh yang kompatibel dengan semua lini OS Windows dan bahkan mungkin dapat “berjalan di Windows XP dan sebelumnya”.

“Infeksi ransomware aktif semakin sulit dikendalikan, ditahan, dan dimitigasi,” kata Walter. Hal ini membuat pencegahan infeksi “lebih penting daripada sebelumnya mengingat sulitnya pemulihan dari serangan ransomware yang dahsyat”.

Pengguna juga harus dididik tentang metode penyerang dan didorong untuk melaporkan aktivitas yang mencurigakan, lanjut peneliti.
