Iklan Google Mendorong Malware ‘Tervirtualisasi’ yang Dibuat Untuk Penghindaran Antivirus

February 3, 2023 by Coffee Bean

KoiVM adalah plugin untuk pelindung ConfuserEx .NET yang mengaburkan opcode program sehingga mesin virtual hanya memahaminya. Kemudian, saat diluncurkan, mesin virtual menerjemahkan opcode kembali ke bentuk aslinya sehingga aplikasi dapat dijalankan.

“Kerangka kerja virtualisasi seperti KoiVM mengaburkan executable dengan mengganti kode asli, seperti instruksi NET Common Intermediate Language (CIL), dengan kode virtualisasi yang hanya dipahami oleh kerangka kerja virtualisasi,” jelas laporan baru oleh SentinelLabs.

Menyalahgunakan iklan pencarian Google
Selama sebulan terakhir, para peneliti telah melihat peningkatan penyalahgunaan iklan pencarian Google untuk mendistribusikan berbagai malware, termasuk RedLine Stealer, Gozi/Ursnif, Vidar, pencuri Rhadamanthys, IcedID, Raccoon Stealer, dan banyak lagi.

Dalam kampanye yang sedang berlangsung yang dilihat oleh SentinelLabs, pelaku ancaman mendorong pemuat MalVirt dalam iklan yang berpura-pura untuk perangkat lunak Blender 3D.
