Aktor FIN7 mengirim drive USB Berbahaya ke perusahaan AS dengan ransomware

January 9, 2022 by Søren

FBI telah mengidentifikasi perangkat USB berbahaya yang dikirim ke perusahaan AS dalam beberapa bulan terakhir dengan motif untuk menginfeksi jaringan perusahaan dengan malware dan penurunan muatan lebih lanjut.

Kelompok di balik operasi USB berbahaya ini diketahui sebagai aktor FIN7, yang berada di balik ransomware BlackMatter dan Darkside.

Sesuai laporan FBI, beberapa paket dengan drive USB telah dikirim ke perusahaan AS termasuk industri pertahanan, asuransi, dan transportasi.

Pengiriman dilakukan melalui United Parcel Service dan United States Postal Service. Paket datang dalam dua varian, satu dengan nama Departemen Kesehatan dan Layanan Kemanusiaan AS, dengan beberapa pedoman COVID-19 dan drive USB.

Yang lainnya disamarkan sebagai Paket Amazon dengan dekorasi hadiah, pesan terima kasih, kartu hadiah, dan drive USB. Satu hal yang umum di antara kedua paket ini adalah bahwa drive USB berasal dari merek LilyGo.

Setelah penerima menyambungkan drive USB ini ke perangkat mereka, serangan BadUSB dimulai.

Serangan BadUSB adalah serangan keamanan yang menginfeksi perangkat dengan memprogram ulang drive USB dengan perangkat lunak berbahaya.

Dengan program jahat ini, para aktor dapat mengunduh banyak muatan ke dalam perangkat dan menjadikannya sebagai pintu belakang untuk penyusupan lebih lanjut.

Setelah aktor mendapatkan hak istimewa admin untuk sistem, mereka melanjutkan serangan mereka dengan menyebarkan malware secara lateral di seluruh jaringan yang memengaruhi perangkat rekan lainnya.

Setelah distribusi lateral yang sukses, aktor FIN7 menggunakan beberapa alat untuk menyebarkan ransomware REvil dan BlackMatter. Alat-alat tersebut antara lain Cobalt Strike, Metasploit, Carbanak, TIRION, DICELOADER, GRIFFON, dan Carbanak.
