Kampanye Spyware Massal ‘PseudoManuscrypt’ Menargetkan 35K Sistem

December 18, 2021 by Søren

Para peneliti telah melacak spyware baru – dijuluki “PseudoManuscrypt” karena mirip dengan malware “Manuscrypt” dari kelompok ancaman persisten lanjutan (APT) Lazarus – yang mencoba mencoret-coret dirinya sendiri di lebih dari 35.000 komputer yang ditargetkan di 195 negara.

Peneliti Kaspersky mengatakan dalam laporan Kamis bahwa dari 20 Januari hingga 10 November, aktor di balik kampanye besar-besaran menargetkan organisasi pemerintah dan sistem kontrol industri (ICS) di berbagai industri, termasuk teknik, otomatisasi bangunan, energi, manufaktur, konstruksi, utilitas dan pengelolaan air.

Manuscrypt, alias NukeSped, adalah keluarga alat malware yang telah digunakan dalam kampanye spionase di masa lalu. Salah satunya adalah kampanye spear-phishing Februari yang terkait dengan Lazarus – APT Korea Utara yang produktif – yang menggunakan kluster alat ‘ThreatNeedle’ keluarga malware Manuscrypt untuk menyerang perusahaan pertahanan.

Tim ICS-CERT Kasperskiy pertama kali mendeteksi rangkaian serangan PseudoManuscrypt pada bulan Juni, ketika malware memicu deteksi antivirus yang dirancang untuk mendeteksi aktivitas Lazarus. Namun, gambaran lengkapnya tidak mengarah ke Lazarus, mengingat cipratan puluhan ribu serangan yang tidak biasa dan tidak bertarget.

Namun, Kaspersky kemudian menemukan kesamaan antara PseudoManuscrypt baru dan malware Manuscrypt Lazarus.

Malware PseudoManuscrypt memuat muatannya dari registri sistem dan mendekripsinya, para peneliti menjelaskan, dengan muatan menggunakan lokasi registri yang unik untuk setiap sistem yang terinfeksi.

“Kedua program jahat memuat muatan dari registri sistem dan mendekripsinya; dalam kedua kasus, nilai khusus dalam format CLSID digunakan untuk menentukan lokasi muatan di registri,” kata mereka. “File yang dapat dieksekusi dari kedua program jahat memiliki tabel ekspor yang hampir identik.”
