Ransomware AustraliaNewVarian ESXiArgs Baru Muncul Setelah CISA Merilis Alat Decryptor

February 13, 2023 by Flamango

Setelah Cybersecurity and Infrastructure Security Agency (CISA) AS merilis dekripsi untuk korban yang terkena dampak untuk pulih dari serangan ransomware ESXiArgs, pelaku ancaman telah bangkit kembali dengan versi terbaru yang mengenkripsi lebih banyak data.

Dilaporkan oleh administrator sistem di forum online, varian baru ini memiliki file yang lebih besar dari 128MB akan memiliki 50% data terenkripsi, membuat proses pemulihan lebih menantang.

Perubahan penting lainnya adalah penghapusan alamat Bitcoin dari catatan tebusan. Penyerang mendesak korban untuk menghubungi mereka di Tox untuk mendapatkan informasi wallet.

Saatv peneliti sedang melacak pembayaran dan mungkin telah mengetahui sebelum merilis ransomware bahwa proses enkripsi dalam varian asli relatif mudah untuk dielakkan, pelaku ancaman mengetahui itu.

Sebanyak 1.252 server telah terinfeksi oleh versi baru ESXiArgs per 9 Februari 2023, 1.168 di antaranya adalah infeksi ulang. Dan lebih dari 3.800 host unik telah disusupi.

Sebagian besar infeksi berlokasi di Prancis, AS, Jerman, Kanada, Inggris, Belanda, Finlandia, Turki, Polandia, dan Taiwan.

Aspek penting yang membedakan ESXiArgs dari keluarga ransomware lainnya adalah tidak adanya situs kebocoran data, yang menunjukkan bahwa itu tidak berjalan di model ransomware-as-a-service (RaaS).
