While monitoring the server I can see that the “named” service is using high CPU usage. I have found lots of questions are sent from multiple IP’s. This seems a DNS amplification attack. This attack is a type of distributed denial of service (DDos) attack that takes advantage of the fact that a small DNS question can generate a much larger response. When combined with source address spoofing, an attacker can direct a large volume of network traffic to a target system by initiating relatively small DNS questions.

here are the ip's and where they are coming from

192.126.118.105
174.139.237.142
70.39.67.110
199.115.102.83
173.234.39.133


hccforums.nl
ietf.org

When SOH is down, you can find information at www.sim-outhouse.net (http://www.sim-outhouse.net). The .net is not apart of the .com so it is often fine.

Ickie,

Do you know about the WHOIS at arin.net? For example, with arin.net I can see the IP address 70.39.67.110 belongs to an ISP named Sharknet Colorado USA. Using the IP address in this way could be a clear violation of USA law. You could at least report the IP address to the ISP.

And 174.139.237.142 is from an ISP in California.

The two sites are on different servers running different software (Linux and Windows Server) and the member info is non-transferable between the two so you will need to re-register at the .net site in order to access it fully.

I need to check my home IP. When I went to log on on sat. I got an "Account Disabled" notice come up. If one of those IP's is me, then mine, or my wife's laptops may have been compromised! It may explain why the whole home system seems to slow to a crawl about 50% of the time. (sent from work computer)

True but you can read on the .net with out re-registering.

Your forthrightness is truly refreshing, sir. I suggest you and Ickie chat about scrubbing up your laptops and trying again. I wish you luck in finding the problem files on your machines. If nothing else, a good scan of those laptops should improve their performance for you.

When you do the scan and repair, keep the logs so they can be analyzed for which miserable malware is likely to be at fault. Others of us can then be able to go after it (them) on our own machines.

I'm still having a thorough scrub through though - I'm normally fairly careful about these things, but, you never know........drop your guard for a second and whammo!

these new attacks only last a few hours, if you look at my link (http://www.digitalattackmap.com/#anim=1&color=0&country=ALL&time=16111&view=map )
you will see a lot of resources being used up to control the internet.
I'm afraid "it's the end of our internet as we know it"
we need to band together as the WORLD USERS and demand a stop to this, much of it is at the hands of governments.

I have gone through the dns logs and also monitored the server and found that this is one of the DNS amplification attack over/through our server. In this weekend attack, somebody is trying to use our DNS server to flood somebody else. In this case it will be “denied” packet and it will still go to the flood target, not to mention flooding of our syslog messages log and steal bandwidth from our server.

In order to lock down such attack I disabled the recursion, that is set allow-recursion to "none;" on the server.
I will see what happens tomorrow.

no because it started 4-5 months ago with new tactics, it is a shame my country is doing this to other countries, and they are fighting back, than others got into the fight to prove they can too.
I say enough is enough, it is time to ban all ip's connected with this bull crap.
Go to a new system where we the user has to buy their IP and it is held responsible for their actions.

Glad your staying frosty as usual, Ron, thanks... but be advised: things are acting "funny" here this day. Have been unable to log out for several minutes, though was immediately able to log out from gmail & other sites during the "lock-up". Software change adjustment/attack/bug? Unsure, but am assuring you it is so. 'Preciate you being on top of things, you're better at it than most, in my estimation.
