Hundreds of Thousands of Realtek-based Devices Under Attack from IoT Botnet

A dangerous vulnerability in Realtek chipsets used in hundreds of thousands of smart devices from at least 65 vendors is currently under attack from a notorious DDoS botnet gang. From a report: The attacks started last week, according to a report from IoT security firm SAM, and began just three days after fellow security firm IoT Inspector published details about the vulnerability on its blog. Tracked as CVE-2021-35395, the vulnerability is part of four issues IoT Inspector researchers found in the software development kit (SDK) that ships with multiple Realtek chipsets (SoCs). These chips are manufactured by Realtek but are shipped to other companies, which then use them as the basic System-on-Chip (SoC) board for their own devices, with the Realtek SDK serving as a configurator and starting point for their own firmware. IoT Inspector said they found more than 200 different device models from at least 65 different vendors that had been built around these chips and were using the vulnerable SDK.
