Title: Major Security Breach: Over 9,000 ASUS Routers Compromised by Botnet Attack
In a concerning development for internet security, more than 9,000 ASUS routers have fallen victim to a sophisticated botnet attack, known as “AyySSHush.” This alarming breach was uncovered in March 2025 by the cybersecurity firm GreyNoise, highlighting vulnerabilities in the authentication protocols of these devices.
The attack exploits inherent flaws in router security, taking advantage of legitimate functionalities to create a persistent SSH backdoor within the devices. What sets this incident apart is the backdoor’s placement in the router’s non-volatile memory (NVRAM). This strategic positioning ensures that, even with firmware updates or restarts, the infiltration remains intact, making traditional security measures ineffective.
As the digital landscape becomes increasingly complex, this breach underlines the critical importance of timely security updates and robust authentication mechanisms for all internet-connected devices. Users are strongly advised to secure their routers and monitor their network for any unusual activity to mitigate the risks associated with this ongoing threat.
