Ekstensi berbahaya memungkinkan penyerang mengontrol Google Chrome dari jarak jauh

November 9, 2022 by Coffee Bean

Botnet browser Cloud9 secara efektif merupakan trojan akses jarak jauh (RAT) untuk browser web Chromium, termasuk Google Chrome dan Microsoft Edge, yang memungkinkan pelaku ancaman untuk mengeksekusi perintah dari jarak jauh.

Ekstensi Chrome berbahaya diedarkan melalui saluran alternatif, seperti situs web yang mendorong pembaruan Adobe Flash Player palsu.

Menginfeksi browser Anda
Cloud9 adalah ekstensi browser berbahaya yang membuka pintu belakang browser Chromium untuk melakukan daftar ekstensif fungsi dan kemampuan berbahaya.

Ekstensi terdiri dari tiga file JavaScript untuk mengumpulkan informasi sistem, menambang cryptocurrency menggunakan sumber daya host, melakukan serangan DDoS, dan menyuntikkan skrip yang menjalankan eksploitasi browser.

Zimperium memperhatikan pemuatan eksploit untuk kerentanan CVE-2019-11708 dan CVE-2019-9810 di Firefox, CVE-2014-6332 dan CVE-2016-0189 untuk Internet Explorer, dan CVE-2016-7200 untuk Edge.

Kerentanan ini digunakan untuk menginstal dan mengeksekusi malware Windows secara otomatis di host, memungkinkan penyerang untuk melakukan kompromi sistem yang lebih signifikan.

Modul “clipper” juga hadir dalam ekstensi, terus memantau clipboard sistem untuk kata sandi atau kartu kredit yang disalin.

Cloud9 juga dapat menyuntikkan iklan dengan memuat halaman web secara diam-diam untuk menghasilkan tayangan iklan dan, dengan demikian, pendapatan bagi operatornya.

Terakhir, malware dapat meminta daya tembak host untuk melakukan serangan DDoS layer 7 melalui permintaan HTTP POST ke domain target.

Operator dan target
Peretas di balik Cloud9 diyakini memiliki hubungan dengan grup malware Keksec karena domain C2 yang digunakan dalam kampanye baru-baru ini terlihat dalam serangan Keksec sebelumnya.

Keksec bertanggung jawab untuk mengembangkan dan menjalankan beberapa proyek botnet, termasuk EnemyBot, Tsunamy, Gafgyt, DarkHTTP, DarkIRC, dan Necro.

Korban Cloud9 tersebar di seluruh dunia, dan tangkapan layar yang diposting oleh aktor ancaman di forum menunjukkan bahwa mereka menargetkan berbagai browser.
