Thousands of home and small office routers manufactured by Asus are being infected with a stealthy backdoor that can survive reboots and firmware updates in an attack by a nation-state or another well-resourced threat actor, researchers said.
The unknown attackers gain access to the devices by exploiting now-patched vulnerabilities, some of which have never been tracked through the internationally recognized CVE system. After gaining unauthorized administrative control of the devices, the threat actor installs a public encryption key for access to the device through SSH. From then on, anyone with the private key can automatically log in to the device with administrative system rights.
Durable control
“The attacker’s access survives both reboots and firmware updates, giving them durable control over affected devices,” researchers from security firm GreyNoise reported Wednesday. “The attacker maintains long-term access without dropping malware or leaving obvious traces by chaining authentication bypasses, exploiting a known vulnerability, and abusing legitimate configuration features.”

Those “backdoors” are called RJ-45 jacks. That’s where the bits get in and out.
My ports are on the front of the router. No backdoors for me, checkmate Atheists.
You have to fill them with both ends of a cable or the bits leak on the floor
