Peretas Mendistribusikan Alat Pembobol Kata Sandi untuk PLC dan HMI untuk Menargetkan Sistem Industri

July 19, 2022 by Eevee

Insinyur dan operator industri menjadi target kampanye baru yang memanfaatkan perangkat lunak pembobol kata sandi untuk menguasai Programmable Logic Controllers (PLC) dan mengkooptasi mesin ke botnet.

Perangkat lunak itu “mengeksploitasi kerentanan dalam firmware yang memungkinkannya mengambil kata sandi sesuai perintah,” kata peneliti keamanan Dragos, Sam Hanson. “Selanjutnya, perangkat lunak itu adalah penetes malware, menginfeksi mesin dengan malware Sality dan mengubah host menjadi rekan di botnet peer-to-peer Sality.”

Perusahaan industri keamanan siber mengatakan bahwa eksploitasi pengambilan kata sandi yang tertanam dalam penetes malware dirancang untuk memulihkan kredensial yang terkait dengan Automation Direct DirectLOGIC 06 PLC.

Eksploitasi, dilacak sebagai CVE-2022-2003 (skor CVSS: 7,7), telah digambarkan sebagai kasus transmisi teks yang jelas dari data sensitif yang dapat menyebabkan pengungkapan informasi dan perubahan yang tidak sah. Masalah ini telah diatasi dalam firmware Versi 2.72 yang dirilis bulan lalu.

Infeksi memuncak dalam penyebaran malware Sality untuk melakukan tugas-tugas seperti penambangan cryptocurrency dan peretasan kata sandi secara terdistribusi, sementara juga mengambil langkah-langkah untuk tetap tidak terdeteksi dengan menghentikan perangkat lunak keamanan yang berjalan di workstation yang disusupi.

Terlebih lagi, artefak yang digali oleh Dragos menjatuhkan muatan crypto-clipper yang mencuri cryptocurrency selama transaksi dengan mengganti alamat dompet asli yang disimpan di clipboard dengan alamat dompet penyerang.

Automation Direct bukan satu-satunya vendor yang terkena dampak karena alat tersebut mengklaim mencakup beberapa PLC, human-machine interfaces (HMI), dan file proyek yang mencakup Omron, Siemens, ABB Codesys, Delta Automation, Fuji Electric, Mitsubishi Electric, Pro-face Schneider Electric , Vigor PLC, Weintek, Allen-Bradley dari Rockwell Automation, Panasonic, Fatek, IDEC Corporation, dan LG.

Ini jauh dari pertama kalinya perangkat lunak trojan memilih jaringan teknologi operasional (OT). Pada Oktober 2021, Mandiant mengungkapkan bagaimana binari executable portabel yang sah dikompromikan oleh berbagai malware seperti Sality, Virus, dan Ramnit, antara lain.
