Kerentanan Log4j sekarang digunakan oleh peretas yang didukung negara

December 16, 2021 by Winnie the Pooh

Seperti yang diharapkan, peretas negara-bangsa dari semua jenis telah mengambil kesempatan untuk mengeksploitasi kerentanan kritis yang baru-baru ini diungkapkan (CVE-2021-44228) di library logging berbasis Java Apache Log4j.

Juga dikenal sebagai Log4Shell atau LogJam, kerentanan sekarang digunakan oleh pelaku ancaman yang memiliki kaitan dengan pemerintah di Cina, Iran, Korea Utara, dan Turki, serta broker akses yang digunakan oleh geng ransomware.

Di antara aktor ancaman pertama yang memanfaatkan Log4Shell untuk menjatuhkan muatan adalah grup penambangan cryptocurrency dan botnet, yang mulai menyerang segera setelah kode eksploitasi proof-of-concept tersedia.

Salah satu pelakunya adalah kelompok ancaman Iran Fosfor – juga dilacak sebagai Charming Kitten, APT 35, yang diamati Microsoft “memperoleh dan membuat modifikasi” pada eksploitasi Log4Shell.

Aktor ancaman negara-bangsa lain yang memanfaatkan bug Log4Shell adalah Hafnium, grup peretas yang terkait dengan China.

Microsoft mengatakan bahwa Hafnium sekarang menggunakan Log4Shell dalam serangan terhadap infrastruktur virtualisasi “untuk memperluas penargetan tipikal mereka”.

Terlepas dari aktor negara-bangsa, Microsoft telah mengkonfirmasi bahwa broker yang menyediakan akses jaringan awal ke berbagai kelompok, sebagian besar bermotivasi finansial juga mulai mengeksploitasi kelemahan Log4j.

Broker akses awal biasanya bekerja dengan operasi ransomware-as-a-service (RaaS), di mana mereka menjual akses ke jaringan perusahaan yang disusupi.

Log4Shell juga telah digunakan dalam serangan ransomware dari aktor baru bernama Khonsari, sebuah laporan dari Bitdefender menunjukkan.

Mengingat kerusakan yang dapat disebabkan oleh bug ini, Badan Keamanan Infrastruktur Keamanan Siber (CISA) telah memerintahkan lembaga federal untuk segera menambal sistem yang terpengaruh.
