Geng TA505 Kembali Dengan FlawedGrace RAT yang Baru

October 22, 2021 by Winnie the Pooh

Kelompok kejahatan dunia maya TA505 menghidupkan kembali mesin pembobol keuangannya, melemparkan malware ke berbagai industri dalam gelombang volume rendah yang awalnya dilihat oleh para peneliti meningkat akhir bulan lalu.

Mereka melakukan hal-hal buruk, tetapi mereka sangat rumit sehingga melacaknya sangat menyenangkan, kata Sherrod DeGrippo, wakil presiden, Riset dan Deteksi Ancaman di Proofpoint.

TA505, alias Hive0065, adalah sekelompok penjahat dunia maya yang terlibat dalam penipuan keuangan dan tindakan yang disponsori negara. Peneliti proofpoint menggambarkan grup tersebut sebagai “salah satu aktor yang lebih produktif” yang mereka lacak.

Yang ada di balik kampanye spam terbesar yang pernah dilihat perusahaan: yaitu, distribusi trojan perbankan Dridex. Proofpoint juga telah melacak geng yang mendistribusikan ransomware Locky dan Jaff, trojan perbankan Trick, dan lainnya “dalam volume yang sangat tinggi,” kata Proofpoint.

TA505, yang secara aktif menargetkan banyak industri – termasuk keuangan, ritel, dan restoran – telah aktif setidaknya sejak 2014. Mereka dikenal karena seringnya mengganti malware dan untuk mendorong tren global dalam distribusi malware kriminal.

Sesuai dengan bentuknya, kampanye terbaru geng didistribusikan di berbagai industri. Mereka juga muncul dengan perlengkapan baru, termasuk loader KiXtart yang telah ditingkatkan, loader MirrorBlast yang mengunduh pemecah skrip Rebol, RAT FlawedGrace yang diperbarui, dan lampiran Excel berbahaya yang diperbarui.

Para peneliti mencatat bahwa TA505 sekarang menggunakan beberapa pemuat perantara sebelum pengiriman RAT FlawedGrace, dan mereka dikodekan dalam bahasa skrip yang tidak umum – Rebol dan KiXtart.

Mengingat bahwa TA505 mengubah TTP dan bahwa mereka “dianggap sebagai trendsetter di dunia kejahatan dunia maya,” Proofpoint mengatakan TA505 tidak akan pergi dalam waktu dekat.
