Botnet Dark_nexus Melampaui Botnet Lain Dengan Fitur Baru yang Kuat

April 13, 2020 by Winnie the Pooh

Pada hari Rabu, peneliti dari perusahaan cybersecurity Bitdefender mengatakan bahwa botnet baru yang dijuluki “dark_nexus” mengemas berbagai fitur dan kemampuan yang melampaui botnet yang biasanya ditemukan saat ini.

Dark_nexus memiliki tautan kode ke Mirai dan Qbot, tetapi tim mengatakan sebagian besar fungsi botnet ini asli atau original dari botnet tersebut.

“Meskipun ada beberapa kesamaan fitur dengan botnet IoT yang sebelumnya, bagaimana beberapa modulnya yang telah dikembangkan membuatnya secara signifikan lebih ampuh dan kuat,” kata Bitdefender.

Dark_nexus telah ada selama tiga bulan dan selama waktu ini, tiga versi berbeda telah dirilis. Honeypots telah mengungkapkan bahwa setidaknya ada 1.372 bot yang terhubung ke botnet, dengan mayoritas berada di Cina, Republik Korea, Thailand, dan Brasil.

Serangan yang diluncurkan oleh botnet agak tipikal, dengan satu pengecualian – perintah browser_http_req. Bitdefender mengatakan elemen ini “sangat kompleks dan dapat dikonfigurasi,” dan “itu mencoba untuk menyamarkan lalu lintas sebagai lalu lintas tidak berbahaya yang bisa dihasilkan oleh browser.”

Fitur yang menarik dari botnet ini adalah upaya untuk mencegah perangkat melakukan reboot. Layanan cron dikompromikan dan dihentikan, sementara izin juga dihapus dari executable yang bisa me-restart mesin.

Pengembang botnet diyakini adalah orang Yunani. Helios, penulis botnet terkenal yang telah dan masih menjual layanan DDoS di forum bawah tanah selama beberapa tahun terakhir.
