Sistem Pembajakan Malware KmsdBot Baru Crypto Mining dan Meluncurkan Serangan DDoS

November 15, 2022 by Eevee

Malware penghindar yang baru ditemukan memanfaatkan protokol kriptografi Secure Shell (SSH) untuk masuk ke sistem yang ditargetkan dengan tujuan menambang cryptocurrency dan melakukan serangan penolakan layanan (DDoS) terdistribusi.

Dijuluki KmsdBot oleh Akamai Security Intelligence Response Team (SIRT), malware berbasis Golang telah ditemukan menargetkan berbagai perusahaan mulai dari game hingga merek mobil mewah hingga perusahaan keamanan.

Malware mendapatkan namanya dari executable bernama “kmsd.exe” yang diunduh dari server jarak jauh setelah kompromi yang berhasil. Ini juga dirancang untuk mendukung banyak arsitektur, seperti Winx86, Arm64, mips64, dan x86_64.

KmsdBot hadir dengan kemampuan untuk melakukan operasi pemindaian dan menyebarkan dirinya sendiri dengan mengunduh daftar kombinasi nama pengguna dan kata sandi. Itu juga dilengkapi untuk mengontrol proses penambangan dan memperbarui malware.

Akamai mengatakan target pertama yang diamati dari malware adalah perusahaan game bernama FiveM, mod multipemain untuk Grand Theft Auto V yang memungkinkan pemain mengakses server permainan peran khusus.

Serangan DDoS yang diamati oleh perusahaan infrastruktur web termasuk serangan Layer 4 dan Layer 7, di mana banjir permintaan TCP, UDP, atau HTTP GET dikirim untuk membanjiri sumber daya server target dan menghambat kemampuannya untuk memproses dan merespons.

Temuan ini muncul karena perangkat lunak yang rentan semakin banyak digunakan untuk menyebarkan penambang cryptocurrency, melonjak dari 12% di Q1 2022 menjadi 17% di Q3, menurut data telemetri dari Kaspersky. Hampir setengah dari sampel perangkat lunak penambangan berbahaya yang dianalisis (48%) secara diam-diam menambang Monero (XMR).

“Menariknya, negara yang paling ditargetkan pada Q3 2022 adalah Ethiopia (2,38%), di mana penggunaan dan penambangan cryptocurrency ilegal,” kata perusahaan keamanan siber Rusia. “Kazakhstan (2,13%) dan Uzbekistan (2,01%) mengikuti di tempat kedua dan ketiga.”
