Evil Corp Kembali dengan Kampanye Phising “Dudear” menggunakan Teknik Baru

February 3, 2020 by Winnie the Pooh

Evil Corp atau yang dikenal dengan TA505 adalah grup peretas dari Rusia sedang menjalankan kampanye baru dan melibatkan Microsoft Excel sebagai alat pengiriman payload mereka. 

 

Pada January 30, 2020 kemarin, tim Microsoft Security Intelligence membuat tweet untuk memberi tahu pengguna bahwa Evil Corp telah kembali setelah hiatus pendek. Tim memperingatkan bahwa kampanye phishing baru “Dudear” sudah berjalan, masih menyebarkan Trojan pencuri informasi yang dikenal sebagai GraceWire tetapi Evil Corp melakukannya dengan menggunakan taktik tweak.

 

Tweet tersebut berisi:

“Kampanye baru ini menggunakan redirector HTML yang dilampirkan ke email. Saat dibuka, HTML mengarah ke unduhan Dudear, sebuah file Excel yang memuat makro jahat dan menjatuhkan payload. Sebaliknya, kampanye email Dudear sebelumnya membawa malware sebagai lampiran atau menggunakan URL jahat.”

 

“Ini adalah pertama kalinya Dudear diamati menggunakan redirector HTML. Penyerang menggunakan file HTML dalam berbagai bahasa. Khususnya, mereka juga menggunakan layanan traceback IP untuk melacak alamat IP mesin yang mengunduh file Excel berbahaya tersebut.”

 

Untuk membuat ini berhasil, harus ada campur tangan korban juga. Korban masih perlu membuka file Excel yang diunduh secara otomatis, dan mereka masih harus mengaktifkan suntingan dan konten agar dapat terinfeksi.

 

Cara untuk mencegah adalah jangan aktifkan suntingan file Excel yang tidak Anda minta, dan tentu saja jangan aktifkan konten.
