Mirai OMG is a new variant of the Mirai malware that focuses on infecting IoT and networking equipment with the main purpose of turning these devices into a network of proxy servers used to relay malicious traffic. Fortinet claims this is the first Mirai variant that besides the DDoS function also includes a proxy feature as well. But sources in the infosec community say this may not be 100% true. In theory, it should not be any different from the regular type of traffic that malicious proxy networks have been relaying for years.
