Peringatan keamanan siber: Kelemahan Realtek membuat lusinan merek terkena serangan rantai pasokan

August 27, 2021 by Winnie the Pooh

Sebuah cacat baru-baru ini diungkapkan dalam chipset dari perusahaan semikonduktor Taiwan Realtek sedang ditargetkan oleh botnet berdasarkan malware IoT lama, Mirai.

Perusahaan keamanan Jerman IoT Inspector melaporkan bahwa bug Realtek, dilacak sebagai CVE-2021-35395, memengaruhi lebih dari 200 produk Wi-Fi dan router dari 65 vendor, termasuk Asus, Belkin, China Mobile, Compal, D-Link, LG, Logitec, Netgear, ZTE, dan Zyxel.

Cacat ini terletak di perangkat pengembang perangkat lunak Realtek (SDK) dan saat ini sedang diserang dari kelompok yang menggunakan varian malware IoT, Mirai, yang dirancang untuk berfungsi pada perangkat dengan budget prosesor dan sedikit memori.

Jika serangan berhasil, penyerang akan mendapatkan kontrol penuh atas modul Wi-Fi dan akses root ke sistem operasi perangkat.

Serangan tersebut menyoroti kerentanan dalam rantai pasokan perangkat lunak yang diharapkan oleh Presiden AS Joe Biden dapat ditambal dengan miliaran dolar yang dijanjikan minggu ini oleh Microsoft dan Google.

Sementara Mirai menimbulkan beberapa ancaman terhadap informasi yang disimpan di perangkat seperti router, kerusakan yang lebih besar disebabkan oleh serangan penolakan layanan terdistribusi (DDoS) bertenaga tinggi di situs web yang menggunakan perangkat yang disusupi.

Realtek telah merilis tambalan, tetapi merek perangkat (OEM) perlu mendistribusikannya ke pengguna akhir pada perangkat yang, sebagian besar, tidak memiliki antarmuka pengguna, dan oleh karena itu tidak dapat digunakan untuk mengomunikasikan bahwa tambalan tersedia. Vendor perlu menganalisis firmware mereka untuk memeriksa keberadaan kerentanan.
