In 2019, NSFOCUS Security Labs detected over 400,000 DDoS attacks launched via botnets, a sharp increase compared with 2018 (8323 DDoS attacks). According to our observation, the
botnets running on IoT devices were mainly Mirai and Gafgyt families. These two families were exploited to launch over 60% of DDoS attacks in the first half of 2019. The following figure shows the proportions of high-risk commands observed by NSFOCUS Security Labs in 2018 and 2019.
