Evolusi ransomware JSWorm

May 26, 2021 by Winnie the Pooh

Keluarga JSWorm telah berkembang selama dua tahun dan selama waktu ini telah mengubah model distribusi dan Trojan telah mengalami beberapa pengembangan ulang lengkap.

Sejak kemunculan awal pada tahun 2019, ini telah berubah dari ancaman ransomware skala massal yang memengaruhi sebagian besar pengguna individu menjadi ancaman ransomware pemburu game besar yang menyerang target profil tinggi dan menuntut pembayaran tebusan besar-besaran.

Seperti ancaman ransomware bertarget lainnya saat ini, kunci untuk mencegah insiden infeksi JSWorm adalah pendekatan kompleks untuk mengamankan jaringan organisasi. Kelemahan apa pun dapat menjadi titik masuk bagi pelaku ancaman, baik itu versi perangkat lunak sisi server yang rentan, karyawan yang mengklik tautan berbahaya, kata sandi yang lemah untuk sistem kendali jarak jauh, dan sebagainya.

Untuk meningkatkan pertahanan terhadap ransomware pemburu game besar, sebaiknya lakukan audit keamanan jaringan Anda untuk menemukan dan secara proaktif memperbaiki kelemahan keamanan apa pun.

Rekomendasi lain untuk memaksimalkan keamanan organisasi Anda:

  • Jangan memaparkan layanan desktop jarak jauh (seperti RDP) ke jaringan publik kecuali benar-benar diperlukan dan selalu gunakan kata sandi yang kuat untuk mereka.
  • Pastikan solusi VPN komersial dan perangkat lunak sisi server lainnya selalu diperbarui karena eksploitasi perangkat lunak jenis ini adalah vektor infeksi umum untuk ransomware. Selalu perbarui aplikasi sisi klien.
  • Fokuskan strategi pertahanan Anda untuk mendeteksi pergerakan lateral dan eksfiltrasi data ke internet. Berikan perhatian khusus pada lalu lintas keluar untuk mendeteksi koneksi penjahat dunia maya. Cadangkan data secara teratur. Pastikan Anda dapat mengaksesnya dengan cepat dalam keadaan darurat saat dibutuhkan. Gunakan informasi Threat Intelligence terbaru untuk tetap mengetahui TTP aktual yang digunakan oleh pelaku ancaman.
