Peretas Tiongkok Menargetkan Lembaga Keuangan Taiwan dengan Pintu Belakang Tersembunyi yang baru

February 8, 2022 by Eevee

Sebuah kelompok ancaman persisten lanjutan (APT) China telah menargetkan lembaga keuangan Taiwan sebagai bagian dari “kampanye gigih” yang berlangsung setidaknya selama 18 bulan.

Penyusupantersebut bertujuan pionase, mengakibatkan penyebaran pintu belakang yang disebut xPack, yang memberikan kontrol ekstensif kepada musuh atas mesin yang disusupi, kata Symantec milik Broadcom dalam sebuah laporan yang diterbitkan minggu lalu.

Apa yang penting dari kampanye ini adalah jumlah waktu aktor ancaman mengintai di jaringan korban, memberikan operator banyak kesempatan untuk pengintaian rinci dan menggali informasi yang berpotensi sensitif yang berkaitan dengan kontak bisnis dan investasi tanpa menaikkan bendera merah apapun.

Di salah satu organisasi keuangan yang tidak disebutkan namanya, para penyerang menghabiskan hampir 250 hari antara Desember 2020 dan Agustus 2021, sementara entitas manufaktur memiliki jaringannya di bawah pengawasan mereka selama sekitar 175 hari.

Meskipun vektor akses awal yang digunakan untuk menembus target masih belum jelas, diduga Antlion memanfaatkan kelemahan aplikasi web untuk mendapatkan pijakan dan menjatuhkan pintu belakang khusus xPack, yang digunakan untuk menjalankan perintah sistem, menghapus malware dan alat berikutnya, dan tahap data untuk eksfiltrasi.

Selain itu, aktor ancaman menggunakan pemuat kustom berbasis C++ serta kombinasi alat yang sah seperti AnyDesk dan teknik living-off-the-land (LotL) untuk mendapatkan akses jarak jauh, membuang kredensial, dan mengeksekusi arbitrer perintah.

Temuan ini menambah daftar kelompok negara-bangsa terkait China yang telah menargetkan Taiwan dalam beberapa bulan terakhir, dengan aktivitas siber jahat yang dipasang oleh aktor ancaman yang dilacak saat Tropic Trooper dan Earth Lusca menyerang lembaga pemerintah, perawatan kesehatan, transportasi, dan pendidikan di negara.
