According to recent analysis by secure cloud company Zscaler, there has been a fivefold increase in IoT malware attacks since 2022. Cybersecurity firm Fortinet, in its 2022 IoT threat review identified “over 20 million successful brute force attacks” in 2022.
Most such attacks use compromised devices in a ‘botnet’ to execute a Distributed Denial of Service attack on a third party. New network architectures using techniques such as network slicing should make it possible to isolate compromised IoT devices from the wider Internet, even when the devices are tunning unpatched firmware with known security vulnerabilities.
