Major Cybersecurity Breach: Over 9,000 ASUS Routers Compromised by Persistent Botnet
In a troubling development for internet security, more than 9,000 ASUS routers have fallen victim to a sophisticated cyberattack involving a botnet known as “AyySSHush.” Revealed by the cybersecurity firm GreyNoise in March 2025, this alarming incident takes advantage of vulnerabilities in router authentication mechanisms.
The malicious attack is particularly concerning because it employs legitimate features of the routers to create a lasting SSH backdoor. What sets this breach apart is the backdoor’s placement within the router’s non-volatile memory (NVRAM). This means that even after firmware updates or device reboots, the malicious access point remains intact and functional, thwarting conventional recovery methods.
For users relying on ASUS routers, it is imperative to stay alert and consider checking their devices for potential vulnerabilities. Regular updates and vigilance are essential in the fight against such persistent threats. As technology becomes increasingly integrated into our daily lives, the importance of cybersecurity cannot be overstated. Always ensure that your home network is secure and ready to defend against the evolving landscape of cyber attacks.
