Malware Multi Platform

Worm baru mengubah server Windows, Linux menjadi penambang Monero

December 31, 2020 by Winnie the Pooh

Sebuah Malware berbasis Golang yang baru ditemukan dan menyebar sendiri telah secara aktif menjatuhkan penambang cryptocurrency XMRig di server Windows dan Linux sejak awal Desember.

Malware multi-platform ini juga memiliki kemampuan worm yang memungkinkannya menyebar ke sistem lain dengan melakukan brute-forcing pada layanan publik (mis., MySQL, Tomcat, Jenkins, dan WebLogic) dengan sandi yang lemah seperti yang diungkapkan oleh peneliti keamanan Intezer Avigayil Mechtinger.

Para penyerang di balik kampanye ini telah secara aktif memperbarui kemampuan worm melalui server command-and-control (C2) sejak pertama kali terlihat yang mengisyaratkan malware yang dipelihara secara aktif.

Server C2 digunakan untuk meng-host skrip bash atau PowerShell dropper (tergantung pada platform yang ditargetkan), worm berbasis Golang, dan penambang XMRig dikerahkan untuk secara diam-diam menambang cryptocurrency Monero yang tidak dapat dilacak pada perangkat yang terinfeksi.

Malware secara otomatis akan mati sendiri jika mendeteksi bahwa sistem yang terinfeksi mendengarkan pada port 52013. Jika port tersebut tidak digunakan, worm akan membuka soket jaringannya sendiri.

Untuk bertahan dari serangan brute force yang diluncurkan oleh worm multi-platform baru ini, Anda harus membatasi login dan menggunakan sandi yang sulit ditebak pada semua layanan yang terpapar Internet, serta otentikasi dua faktor jika memungkinkan.
