Malware sekarang menggunakan sertifikat penandatanganan kode NVIDIA yang dicuri

March 6, 2022 by Søren

Pelaku ancaman menggunakan sertifikat penandatanganan kode NVIDIA yang dicuri untuk menandatangani malware agar tampak tepercaya dan memungkinkan driver jahat dimuat di Windows.

Minggu ini, NVIDIA mengonfirmasi bahwa mereka mengalami serangan siber yang memungkinkan pelaku ancaman mencuri kredensial karyawan dan data kepemilikan.

Kelompok pemerasan, yang dikenal sebagai Lapsus$, menyatakan bahwa mereka mencuri 1TB data selama serangan dan mulai membocorkan data secara online setelah NVIDIA menolak untuk bernegosiasi dengan mereka.

Setelah Lapsus$ membocorkan sertifikat penandatanganan kode NVIDIA, peneliti keamanan dengan cepat menemukan bahwa sertifikat tersebut digunakan untuk menandatangani malware dan alat lain yang digunakan oleh pelaku ancaman.

Menurut sampel yang diunggah ke layanan pemindaian malware VirusTotal, sertifikat yang dicuri digunakan untuk menandatangani berbagai malware dan alat peretasan, seperti suar Cobalt Strike, Mimikatz, pintu belakang, dan trojan akses jarak jauh.

Misalnya, satu aktor ancaman menggunakan sertifikat untuk menandatangani trojan akses jarak jauh Quasar [VirusTotal], sementara orang lain menggunakan sertifikat untuk menandatangani driver Windows [VirusTotal].
