Major Cybersecurity Breach: Over 9,000 ASUS Routers Compromised by Resilient Botnet Attack
In a concerning development for home network security, a sophisticated botnet attack has compromised more than 9,000 ASUS routers. Identified as “AyySSHush,” this threat was brought to light in March 2025 by the cybersecurity experts at GreyNoise, who uncovered its alarming mechanics.
The attack takes advantage of authentication vulnerabilities inherent in the routers, allowing perpetrators to exploit legitimate features of the devices. Once infiltrated, the routers are subjected to a persistent SSH backdoor, a malicious access point that remains lodged in the router’s non-volatile memory (NVRAM). This means that even if users attempt to update their firmware or restart their devices, the backdoor remains operational—thwarting traditional remediation strategies.
As the implications of this breach unfold, users of affected ASUS routers are urged to take immediate precautionary measures. It’s vital to monitor network activity closely and consider implementing additional security protocols to safeguard personal data. This incident underscores the importance of robust cybersecurity practices, especially in an era where more devices are connected to home networks than ever before.
Stay vigilant and ensure your network security is stronger than ever.
