MySQL "Attacks"?

[TheBattleship]

Hi Guys,

I run a Windows 2003 Server (no flaming please – it’s part of the job!), which hosts various websites and forums.  Recently, I decided to install Cain and Able on it just to see what unencrypted traffic was being passed through (ie bad coding).  Unfortunately, this is what I discovered [next post].

I’m not overly concerned, because although I am running a MySQL server, the “root” account isn’t actually called “root”.  How can I stop this “attack” from happening and using up bandwidth and clock cycles?

Cheers,

Matt

Set a firewall to drop all traffic from that IP both in and out.

Done. By the looks of it, he's still trying(!)

I also identified the ISP and sent an abuse email to them.

i always wondered, do they ever check those abuse e-mails?

His ISP wont do crap. Just follow VaKo's advice.

A lot of these are from bot networks and random searches for vulnerable networks, so this is only a bandaid against one person. If there is a hole in your software, patch it, or you are just setting yourself up for more attacks. Check this article: http://isc.sans.org/diary.html?storyid=4294

Most of these attacks are automated, so the user has very little to do other than click a button to start the process rolling.

After various tests, I configured IPSec to drop packets to the port that MySQL was running on, if they came from the internet NIC (as the application that required MySQL didn't need to be accessed from outside the network.

Thanks for everyone's help!
