Brickerbot, vigilante software aiming to kill malicious botnets by killing IoT devices The last few months has seen escalating botnet activity on the Internet. The botnet operators are targeting non-existent security in certain Internet of Things devices. Some devices, like wireless security cameras or baby monitors, are not only connected to the Internet, but have gaping security holes. Using those holes, botnet operators have ammassed vast flotillas of Internet devices that can be commanded to attack targets on the Internet. Last fall several attacks, larger than any previously seen, attacked several large sites and even brought down critical Internet infrastructure on a few instances. The Brickerbot appears to be a Botnet purposed with destroying those malicious botnets. One hopes the cure is better than the illness.
Hidden Cobra - North Korea's DDoS Botnet infrastructure

The Department of Homeland Security and the FBI have jointly announced detection of a "BOTNET" operated by "cyber actors" of the North Korean government. They are targeting the media, aerospace, financial, and critical infrastructure sectors. They've identified IP addresses associated with a distributed malware system called DeltaCharlie, that manages North Korea’s distributed denial-of-service (DDoS) botnet infrastructure.

The HIDDEN COBRA group primarily targets computers running older, unsupported, versions of Microsoft Windows. They also target Adobe's Flash Player. The vulnerabilities exploited are known, so the simple cure is to update your system to later versions of Windows or to apply security patches.
