DoS Attack on Cisco Routers
Posted on 2014-01-14
I have just resubscribed to EE because the company I work for appears to be subject to DDoS attack.
The attack is coming from 79.173.X.X and it using port 1029 to attack port 4500 on our router. The application is identified as 'Solid Mux'. When I did some research I found the following statement:
“The port 1029 is a Registered port. It is one of the first of this kind after the Well Known ports. A user must have privileged access, such as administrator access, to open Well Known ports from 0 to 1023. The Registered ports can be opened by other programs and users. It is used by the Solid Mux Server. The port 1029 is vulnerable to worms, Trojans and other malicious software.”
Can someone please help with a access-list to block the ip the address?
