Analysis Summary

A new variant of Mirai exploiting a large number of vulnerabilities. This variant leveraged 13 different vulnerabilities targeting routers, surveillance products, and other IoT devices. Though all of these vulnerabilities have been seen in various Mirai variants, this is the first variant containing exploits for all 13.
