Malware Baru Mencuri Kata Sandi Mac dan Mengirimkannya Dengan Telegram

March 29, 2023 by Flamango

Malware baru, MacStealer, ditemukan menginfeksi Intel dan Apple Silicon Mac, serta mencuri kata sandi, info kartu kredit, dan data pribadi lainnya.

MacStealer memiliki kemampuan untuk mengambil dokumen, cookie browser, dan informasi login dari Mac target. Secara khusus juga berfungsi pada Mac yang menjalankan macOS Catalina atau lebih baru, berjalan pada chip Intel atau Apple Silicon.

Perangkat lunak mengambil kredensial dan cookie dari browser Firefox, Google Chrome, dan Brave, mengekstrak database Keychain, dan mencoba untuk mengamankan berbagai jenis file.

Meskipun menarik Keychain tampak seperti bahaya besar bagi pengguna, serangan tersebut melibatkan pengambilan Keychain secara grosir, tanpa mengakses data di dalamnya. Basis data diambil dan dikirim ke penyerang oleh Telegram, tetapi masih dienkripsi.

Pelaku ancaman yang menjual akses ke MacStealer seharga $100 per build mengatakan bahwa Keychain yang diekstraksi hampir tidak mungkin diakses tanpa kata sandi utama.

Item lain dalam daftar “fitur yang akan datang” termasuk pengurasan cryptowallets, alat untuk menghasilkan build baru, shell terbalik, pengunggah khusus, dan panel kontrol.

Pada saat yang sama mengambil file dan data, MacStealer menggunakan Telegram untuk mengirimkan informasi pilihan ke saluran tertentu. Kompilasi ZIP terpisah kemudian dibagikan ke bot Telegram yang dikendalikan oleh peretas.

Mencoba membuka file akan memunculkan permintaan kata sandi macOS palsu, yang kemudian digunakan alat tersebut untuk mengakses file lain di sistem.

Uptycs merekomendasikan agar pengguna memperbarui sistem Mac dengan tambalan dan pembaruan, serta disarankan untuk hanya mengizinkan penginstalan file dari sumber terpercaya.
