Peretas China, “LuoYu”, Menggunakan Serangan Man-on-the-Side untuk Menyebarkan Backdoor WinDealer

June 4, 2022 by Søren

Seorang aktor ancaman persisten (APT) canggih berbahasa China yang “sangat canggih” yang dijuluki LuoYu telah diamati menggunakan alat Windows berbahaya yang disebut WinDealer yang dikirimkan melalui serangan man-on-the-side.

“Pengembangan terobosan ini memungkinkan aktor untuk memodifikasi lalu lintas jaringan dalam perjalanan untuk memasukkan muatan berbahaya,” kata perusahaan keamanan siber Rusia Kaspersky dalam sebuah laporan baru. “Serangan seperti itu sangat berbahaya dan menghancurkan karena tidak memerlukan interaksi apa pun dengan target untuk mengarah pada infeksi yang berhasil.”

Dikenal aktif sejak 2008, organisasi yang ditargetkan oleh LuoYu sebagian besar adalah organisasi diplomatik asing yang didirikan di Tiongkok dan anggota komunitas akademik serta perusahaan keuangan, pertahanan, logistik, dan telekomunikasi.

Penggunaan WinDealer oleh LuoYu pertama kali didokumentasikan oleh perusahaan keamanan siber Taiwan TeamT5 pada Konferensi Analis Keamanan Jepang (JSAC) pada Januari 2021. Kampanye serangan berikutnya telah menggunakan malware untuk menargetkan entitas Jepang, dengan infeksi terisolasi dilaporkan di Austria, Jerman, India, Rusia, dan AS

Alat lain yang menonjol di gudang malware musuh yang kurang dikenal termasuk PlugX dan penerusnya ShadowPad, keduanya telah digunakan oleh berbagai pelaku ancaman China untuk mengaktifkan tujuan strategis mereka. Selain itu, aktor tersebut diketahui menargetkan perangkat Linux, macOS, dan Android.

WinDealer, pada bagiannya, telah dikirimkan di masa lalu melalui situs web yang bertindak sebagai lubang berair dan dalam bentuk aplikasi trojan yang menyamar sebagai pesan instan dan layanan hosting video seperti Tencent QQ dan Youku.
