A relatively new malware family known as Hajime is worming its way through DVRs, CCTV systems, and other poorly-protected Internet of Things (IoT) devices. The malware is similar to Mirai in that it uses built-in username and password combinations to brute-force its way into unsecured devices with open Telnet ports. Hajime doesnt rely on a command and control server (C&C) but instead leverages a peer-to-peer network to send command modules to all its infected devices, which makes the malware more resistant to takedowns.”]
