Thousands of ASUS WRT routers, mostly end-of-life or outdated devices, have been hijacked in a global campaign called Operation WrtHug that exploits six vulnerabilities.

Over the past six months, scanners looking for ASUS devices compromised in Operation WrtHug identified “roughly 50,000 unique IPs” around the globe.

Most of the compromised devices have IP addresses located in Taiwan, while others are distributed across Southeast Asia, Russia, Central Europe, and the United States.
