Devices infected by Mirai continuously scan the internet for the IP address of Internet of things (IoT) devices. Mirai includes a table of IP Address ranges that it will not infect. Mirai then identifies vulnerable IoT devices using a table of default usernames and passwords, and logs into them to infect them with the Mirai malware. There are thousands of IoT devices which use default settings which makes them vulnerable to infection.
Infected devices will continue to function normally, except being slight sluggishness and increased use of bandwidth. After a reboot, the device will be reinfected within minutes, identify other malware, remove them and block remote administration ports. Then the device will monitor a command and control server which indicates the target of an attack.
