Threat update

A newly documented malware family named KATARU is hijacking internet-facing Linux devices, including routers and other IoT equipment, by guessing weak or default Telnet passwords. Once inside, it takes root-level control, embeds itself so it survives reboots, and enlists the device in a Mirai-style botnet used for large-scale DDoS attacks. Any organization with connected devices that are exposed to the internet, unpatched, or protected by default credentials should review its exposure now.
