Malware Emotet sekarang mencuri kartu kredit dari pengguna Google Chrome

June 11, 2022 by Søren

Botnet Emotet sekarang mencoba menginfeksi calon korban dengan modul pencuri kartu kredit yang dirancang untuk mengumpulkan informasi kartu kredit yang disimpan di profil pengguna Google Chrome.

Setelah mencuri info kartu kredit (yaitu, nama, bulan dan tahun kedaluwarsa, nomor kartu), malware akan mengirimkannya ke server command-and-control (C2) yang berbeda dari yang digunakan modul pencuri kartu Emotet.

“Pada 6 Juni, Proofpoint mengamati modul Emotet baru dijatuhkan oleh botnet E4,” kata tim Proofpoint Threat Insights.

“Yang mengejutkan kami, itu adalah pencuri kartu kredit yang hanya menargetkan browser Chrome. Setelah detail kartu dikumpulkan, mereka dipindahkan ke server C2 yang berbeda dari pemuat modul.”

Perubahan perilaku ini terjadi setelah peningkatan aktivitas selama bulan April dan peralihan ke modul 64-bit, seperti yang terlihat oleh kelompok riset keamanan Cryptolaemus.

Satu minggu kemudian, Emotet mulai menggunakan file pintasan Windows (.LNK) untuk menjalankan perintah PowerShell untuk menginfeksi perangkat korban, menjauh dari makro Microsoft Office yang sekarang dinonaktifkan secara default mulai awal April 2022.

Malware Emotet dikembangkan dan disebarkan dalam serangan sebagai trojan perbankan pada tahun 2014. Malware Emotet telah berkembang menjadi botnet yang digunakan kelompok ancaman TA542 (alias Mummy Spider) untuk mengirimkan muatan tahap kedua.

Ini juga memungkinkan operatornya untuk mencuri data pengguna, melakukan pengintaian pada jaringan yang dilanggar, dan bergerak secara lateral ke perangkat yang rentan.

Emotet dikenal karena menjatuhkan muatan trojan malware Qbot dan Trickbot pada komputer korban yang disusupi, yang digunakan untuk menyebarkan malware tambahan, termasuk suar Cobalt Strike dan ransomware seperti Ryuk dan Conti.
