XLoader

Malware XLoader mencuri login dari sistem macOS dan Windows

July 22, 2021 by Winnie the Pooh

Malware yang sangat populer untuk mencuri informasi dari sistem Windows telah dimodifikasi menjadi jenis baru yang disebut XLoader, yang juga dapat menargetkan sistem macOS.

XLoader saat ini ditawarkan di forum bawah tanah sebagai layanan pemuat botnet yang dapat “memulihkan” kata sandi dari web browser dan beberapa klien email (Chrome, Firefox, Opera, Edge, IE, Outlook, Thunderbird, Foxmail).

Berasal dari pencuri info Formbook untuk Windows, XLoader muncul Februari lalu dan semakin populer, diiklankan sebagai botnet lintas platform (Windows dan macOS) tanpa dependency.

Hubungan antara dua bagian malware dikonfirmasi setelah anggota komunitas XLoader merekayasa balik dan menemukan bahwa itu memiliki executable yang sama dengan Formbook.

Pengiklan menjelaskan bahwa pengembang Formbook berkontribusi banyak dalam pembuatan XLoader, dan kedua malware tersebut memiliki fungsi yang serupa (mencuri kredensial login, menangkap tangkapan layar, mencatat penekanan tombol, dan mengeksekusi file berbahaya).

Pelanggan dapat menyewa versi malware macOS seharga $49 (satu bulan) dan mendapatkan akses ke server yang disediakan penjual. Dengan menjaga infrastruktur komando dan kontrol terpusat, penulis dapat mengontrol bagaimana klien menggunakan malware.

Versi Windows lebih mahal karena penjual meminta $59 untuk lisensi satu bulan dan $129 untuk tiga bulan.

Peneliti Check Point mengatakan bahwa XLoader cukup tersembunyi sehingga sulit bagi pengguna non-teknis biasa untuk menemukannya.

Mereka merekomendasikan penggunaan Autorun macOS untuk memeriksa nama pengguna di OS dan untuk melihat ke folder LaunchAgents [/Users/[username]/Library/LaunchAgents] dan menghapus entri dengan nama file yang mencurigakan (nama yang tampak acak).
