Smurf Attacks?????

Prisoner6409

I have been having some issues with my Internet connection lately, slow downloads and some dropped lines, as I'm with Eircom and others here have reported similar issues from time to time I was not that concerned and other than a call to Eircom support I was going to do just that. In the meantime I checked the logs on my router/modem and I came across this in the Security Log on my Router/Modem:

When I googled it(smurf) I saw a lot about a smurf attack. Does the log indicate an attack on my system. I have seen it a few times in the last week since I began checking the log. The only other strange thing(to me) is sometimes the log will display 2 mac address entries for my PC, and another mac address with no description, like this:

ip=192.168.2.2 mac=00-04-4B-15-AB-A4 name=Gerrys-PC
ip=192.168.2.3 mac=00-04-4B-15-AB-A4 name=Gerrys-PC
ip=192.168.2.4 mac=00-1F-5B-6A-1C-E5

I'm not sure if anything is related here but am a bit concerned about the smurf issue as all I could find when I googled it was articles about attacks. Anyone know if the above is normal or is there something I should be doing about it. I have KIS 2010 installed and up to date and am using Kasperskys firewall not the windows one.

That is def a DOS attack.. I personally would be running malwarebytes and then a full AV scan..

It's a false alarm. 169.254.x.x is used by windows when it cant get an IP address. My guess is that you have a dodgy network cable or maybe
interference on your wireless network.

BTW. 00-1F-5B-6A-1C-E5 is from MAC address from an Apple device maybe an iphone.

Thanks guys. I'm leaning toward a dodgy line. I've noticed my SN Ratio which was never great(6db) is sometimes reading 0.5 db or even 0.0db. Time to ring Eircom I guess.
