Today, Ralph Nguyen wrote a post on "The IoT Botnet Wars: How to Harden Linux Devices from DoS Attacks" on Electronicdesign.com.
While fighting botnets like Mirai and BrickerBot with another botnet, Hajime, may help prevent denial-of-service attacks on the IoT, the best defense is a basic system security-hardening plan.
An ongoing battle being waged is leveraging insecure Linux-based Internet of Things (IoT) devices. BrickerBot (see "Beware BrickerBot, the IoT Killer") is a recent malware strain attacking connected devices and causing them to “brick,” making an electronic device completely useless in a permanent denial-of-service (PDoS) attack. It may be a case of grey hat hacking and a direct response to the Mirai botnet distributed denial-of-service (DDoS) attack that enslaved IoT devices
