Peneliti Mengungkap APT Baru “Metador ” yang Menargetkan Telco, ISP, dan Universitas

September 25, 2022 by Søren

Seorang aktor ancaman yang sebelumnya tidak terdokumentasi dengan asal tidak diketahui telah dikaitkan dengan serangan yang menargetkan telekomunikasi, penyedia layanan internet, dan universitas di berbagai negara di Timur Tengah dan Afrika.

“Operator sangat menyadari keamanan operasi, mengelola infrastruktur yang tersegmentasi dengan hati-hati per korban, dan dengan cepat menerapkan tindakan pencegahan yang rumit dengan adanya solusi keamanan,” kata peneliti dari SentinelOne dalam sebuah laporan baru.

Perusahaan keamanan siber menamai grup Metador dengan mengacu pada string “Saya meta” di salah satu sampel malware mereka dan karena respons bahasa Spanyol dari server command-and-control (C2).

Aktor ancaman dikatakan telah terutama berfokus pada pengembangan malware lintas platform dalam mengejar tujuan spionase. Keunggulan lain dari kampanye ini adalah jumlah gangguan yang terbatas dan akses jangka panjang ke target.

Ini termasuk dua platform malware Windows yang berbeda yang disebut metaMain dan Mafalda yang secara tegas dirancang untuk beroperasi di dalam memori dan menghindari deteksi. metaMain juga bertindak sebagai saluran untuk menyebarkan Mafalda, implan interaktif fleksibel yang mendukung 67 perintah.

metaMain, pada bagiannya, kaya fitur sendiri, memungkinkan musuh untuk mempertahankan akses jangka panjang, mencatat penekanan tombol, mengunduh dan mengunggah file arbitrer, dan mengeksekusi shellcode.

Sebagai tanda bahwa Mafalda secara aktif dikelola oleh pengembangnya, malware tersebut memperoleh dukungan untuk 13 perintah baru antara dua varian yang dikompilasi pada bulan April dan Desember 2021, menambahkan opsi untuk pencurian kredensial, pengintaian jaringan, dan manipulasi sistem file.
