Participation of IoT Devices in DDoS Attacks
According to our observation, there were a total of more than 1,280,000 IP addresses of abnormal IoT devices around the world, accounting for 2.1% of all global IoT devices. Of all those abnormal IoT devices, 170,000 were involved in DDoS attacks, making up 13.08% of the total.
Geographical Distribution of IoT Devices Involved in DDoS Attacks
By analyzing the global distribution of IoT devices involved in DDoS attacks, we found that most of such devices were located in China, mainly because the data collection probes of IoT devices
deployed in China were more than those deployed overseas. China, Britain, Russia, the USA, and Vietnam were top 5 countries housing the most devices.
Distribution of IoT Devices Involved in DDoS Attacks by Type
Routers and cameras are the major sources of IoT device-based attacks. Regarding device types, the main types of IoT devices involved in DDoS attacks were routers and cameras, accounting for about 90%. This is consistent with the type distribution of IoT devices.
