Mirai attempts to connect to IoT devices using telnet protocol with the help of default or weak passwords to take control of the device. Reaper, on the other hand, is more sophisticated in its attack, and uses exploitations on unpatched devices to overpower. The firm further explains that the botnet can continue growing, and connect to all types of criminal activities. It has been already proliferating among multiple devices connected to million others. It has already been found taking control of IoT devices including routers and IP cameras, from companies such as D-Link, TP-Link, Netgear, and Linksys.

To keep IoT botnet, or any botnet attacks at bay, organizations should regularly monitor the performance of their network for any suspicious behavior. It is utmost important to ensure all software are running up to date with latest security patches. For employees, it is essential to avoid accessing insecure content on the connect devices or the network that could put the ecosystem at risk. These include phishing emails, downloading unknown attachments or clicking insecure links.
If the network is running at risk of botnet attack, there are some anti-botnet tools such as firewalls and antivirus software which can aid in detection and removal of malicious software. Lastly, if the device falls victim to the attack, it requires shutting down of the control and command (C&C) server that controls the botnet.
