Malware - Denial-of-service - DDoS - Punch - Expansion

Its source code was leaked in 2016, allowing any miscreant to launch their own incarnation of the software nasty.

This latest flavor of Mirai attempts to compromise WePresent projectors, D-Link video cameras, LG digital signage TVs, and routers from Netgear, D-Link, and Zyxel, by exploiting vulnerabilities in firmware, and rope them into its remote-controlled botnets. At that point, the commandeered equipment can be instructed from afar to find and infect other devices, launch DDoS attacks, and other mischief.

Unit - Variant - WePresent - WiPG-1000 - Wireless

"In particular, Unit 42 found this new variant targeting WePresent WiPG-1000 Wireless Presentation systems, and in LG Supersign TVs," the researchers said. "Both these devices are intended for use by businesses. This development indicates to us a potential shift to using Mirai to target enterprises."

In total, Unit 42 said, the new strain of the malware packed an...
