Upaya Kedua Hacker Tim Tonto Tiongkok untuk Menargetkan Grup Perusahaan Keamanan Siber-IB Gagal

February 15, 2023 by Flamango

Pelaku ancaman persisten tingkat lanjut (APT), dikenal sebagai Tim Tonto, melakukan serangan yang gagal terhadap perusahaan keamanan siber Group-IB pada Juni 2022.

Perusahaan tersebut mendeteksi dan memblokir email phishing berbahaya yang berasal dari grup yang menargetkan karyawannya. Ini merupakan serangan kedua yang ditujukan ke Grup-IB, yang pertama terjadi pada Maret 2021.

Disebut Bronze Huntley, Cactus Pete, Earth Akhlut, Karma Panda, dan UAC-0018, Tim Tonto adalah kelompok peretas Cina yang diduga telah dikaitkan dengan serangan yang menargetkan berbagai organisasi di Asia dan Eropa Timur.

Aktor ini diketahui aktif setidaknya sejak tahun 2009 dan dikatakan memiliki hubungan dengan Departemen Ketiga (3PLA) Shenyang TRB Tentara Pembebasan Rakyat (Unit 65016).

Rantai serangan melibatkan umpan spear-phishing yang berisi lampiran berbahaya yang dibuat menggunakan perangkat eksploitasi Royal Road Rich Text Format (RTF) untuk menjatuhkan backdoor seperti Bisonal, Dexbia, dan ShadowPad.

Trend Micro pada tahun 2020 mengungkap bahwa metode sedikit berbeda yang digunakan oleh pelaku ancaman di alam liar adalah penggunaan alamat email perusahaan yang sah, kemungkinan besar diperoleh dengan phishing, untuk mengirim email ke pengguna lain.
