| Re: IPs From China
I was fed up with Asian port scans and ended up blocking IPs from 222.0.0.0 - 222.255.255.255 (I think is the majority of allocated Asian IPs)...
I dunno if it is the OPTIMAL thing to do, but it works.

Scans on the ephemeral ports beginning with 1025 are almost as common as scans of port 445. Unless you are really getting hammered (hundreds of scans per minute), it is just normal internet background noise and nothing to worry about since your firewall is blocking it.
My network typically receives hundreds of such scans daily, and thousands of port 445 scans. Many thanks to Bill Gates et al for exposing DCOM and SMB protocols to the world by default and making them such tempting targets for the evil dooers.

Post a sample of source IPs and the destination & source port numbers ... maybe that'll get some matches ! |

Redmond, WA | I have been recieving a large number of attacks from China in the last few days--I see IP addresses from China in my firewall logs.
Is anybody else seeing something similar? |
