getting attacked, what can I do

Post by frankoamiricano »

Some of my forums are really slow, I see so much traffic in the logs like this:

Code: Select all - - [24/Jan/2005:14:55:59 -0800] "GET /viewtopic.php?t=9121&highlight=%2527%252Esystem(chr(112)%252Echr(101)%252Echr(114)%252Echr(108)%252Echr(32)%252Echr(45)%252Echr(101)%252Echr(32)%252Echr(34)%252Echr(112)%252Echr(114)%252Echr(105)%252Echr(110)%252Echr(116)%252Echr(32)%252Echr(113)%252Echr(40)%252Echr(106)%252Echr(83)%252Echr(86)%252Echr(111)%252Echr(119)%252Echr(77)%252Echr(115)%252Echr(100)%252Echr(41)%252Echr(34))%252E%2527 HTTP/1.0" 200 23889 "-" "Mozilla/4.0"
What is this, and what can I do to block these and restore my server to normal. I am running the updated phpBB as well, so I dont think they are causing any hard other than stealing connections.

You should read the thread: Users Online Count High and amend your common.php file as advised there.

Hey... I'm getting hammered by the same attack. The easy .htaccess fix I found is to do the following (granted you can modify your .htaccess and you can use mod rewrite)

Code: Select all

RewriteEngine on

RewriteCond %{THE_REQUEST} .*/phpBB2/viewtopic.php.*highlight.*system.*
RewriteRule .* - [F]
That will give all requests to viewtopic.php with highlighting of the term system a 403 forbidden error.

Good luck!
