TinyCryptor

Geng ransomware menargetkan bisnis Rusia dalam serangan terkoordinasi yang jarang terjadi

September 25, 2020 by Winnie the Pooh

Perusahaan keamanan Group-IB mengatakan telah mengidentifikasi grup kejahatan siber baru yang, selama enam bulan terakhir, telah berulang kali dan dengan sengaja menargetkan bisnis Rusia dengan serangan malware dan ransomware.

Dinamakan OldGremlin, Group-IB mengatakan para peretas berada di balik serangan yang ditargetkan dengan ransomware strain baru yang disebut TinyCryptor (alias decr1pt).

“Mereka telah mencoba untuk menargetkan hanya perusahaan Rusia sejauh ini,” Oleg Skulkin, analis DFIR senior Grup-IB, mengatakan kepada ZDNet minggu ini.

“Ini sangat tidak biasa bagi geng berbahasa Rusia yang memiliki aturan tak terucapkan tentang tidak menargetkan Rusia dan negara-negara pasca-Soviet.”

Serangan OldGremlin biasanya dimulai dengan email spear-phishing yang membawa file ZIP yang mengandung malware, yang biasanya akan menginfeksi korban dengan trojan backdoor bernama TinyNode.

Ini memberi penyerang pijakan awal di jaringan perusahaan, di mana para peretas menyebar secara lateral ke sistem lain dan kemudian menyebarkan ransomware pada tahap akhir serangan mereka.

Setelah jaringan dienkripsi, kru OldGremlin biasanya meminta pembayaran tebusan sekitar $50.000 menggunakan pesan yang ditinggalkan di sistem yang terinfeksi dan mengarah kembali ke alamat ProtonMail.

Skulkin mengatakan Group-IB telah mengidentifikasi grup OldGremlin pada bulan Agustus, tetapi serangan grup tersebut dimulai pada bulan Maret, dengan email phishing mereka menggunakan berbagai macam umpan, mulai dari menyamar sebagai jurnalis yang mencari wawancara hingga menggunakan demonstrasi anti-pemerintah di Belarusia sebagai pembuka percakapan.
