Peretasan besar-besaran yang didanai negara China menghantam perusahaan di seluruh dunia, menurut laporan

November 21, 2020 by Winnie the Pooh

Peneliti telah menemukan kampanye peretasan besar-besaran yang menggunakan alat dan teknik canggih untuk menyusupi jaringan perusahaan di seluruh dunia. Para peretas, kemungkinan besar dari kelompok terkenal yang didanai oleh pemerintah China, dilengkapi dengan alat siap pakai dan alat yang dibuat khusus. Salah satu alat tersebut mengeksploitasi Zerologon, nama yang diberikan untuk kerentanan server Windows, yang ditambal pada bulan Agustus, yang dapat memberi penyerang hak istimewa administrator instan pada sistem yang rentan.

Symantec menggunakan nama kode Cicada untuk grup tersebut, yang diyakini secara luas didanai oleh pemerintah China dan juga membawa nama APT10, Stone Panda, dan Cloud Hopper dari organisasi penelitian lain. Grup, yang tidak memiliki hubungan atau afiliasi dengan perusahaan mana pun yang menggunakan nama Cicada, telah aktif dalam peretasan bergaya spionase setidaknya sejak 2009 dan hampir secara eksklusif menargetkan perusahaan yang terkait dengan Jepang. Meskipun perusahaan yang ditargetkan dalam kampanye baru-baru ini berlokasi di Amerika Serikat dan negara lain, semuanya memiliki hubungan dengan Jepang atau perusahaan Jepang.

Symantec menghubungkan serangan tersebut ke Cicada berdasarkan sidik jari digital yang ditemukan di malware dan kode serangan. Sidik jari termasuk obfuscation techniques dan kode shell yang terlibat dalam pemuatan samping DLL serta ciri-ciri berikut yang dicatat dalam laporan tahun 2019 ini dari perusahaan keamanan Cylance:
1. DLL tahap ketiga memiliki ekspor bernama “FuckYouAnti”
2. DLL tahap ketiga menggunakan teknik CppHostCLR untuk menginjeksi dan menjalankan rakitan loader .NET
3. .NET Loader dikaburkan dengan ConfuserEx v1.0.0
4. Muatan terakhir adalah QuasarRAT — backdoor open source yang digunakan oleh Cicada di masa lalu
