To be sure I'm understanding correctly, you're saying your nuke config.php file was changed. Is that correct?

yes.was changend one parameter(1970 to 1979) in the config. a friendly attack.... see the ftp log file:

Mon Feb 22 02:48:28 2010 0 81.72.118.167 4475 /home/mysite/public_html/folder/config.php
Mon Feb 22 02:48:52 2010 0 81.72.118.167 4379 /home/mysite/public_html/folder/config.php

A friendly attack? Have you also examined your server error log to see how he got in? Or are those the only log entries for that IP?

hi raven.friendly because i think that he could make many damages if he want...... the problem is that the log file has tracked only this two trace:

Mon Feb 22 02:48:28 2010 0 81.72.118.167 4475 /home/mysite/public_html/folder/config.php
Mon Feb 22 02:48:52 2010 0 81.72.118.167 4379 /home/mysite/public_html/folder/config.php

how is possible to see without ftp password the exact folder where the config is located??

Do you have anonymous ftp ? If so check the settings for this maybe they have changed. I have been hacked through this and with the uploaded shell script its possible to read everything.

You need to check your folders for new unknown files e.g. mshell.php.
However its good practice to change all passwords and have you site under control I mean check it daily also the logs if possible.
I don´t know if the problem was caused through one of your user because I believe there are different ways. My issue was a changed anonymous ftp access.

Earlier when I used SPChat hackers used it's smileyupload.php to upload new index.php and config.php to my site, so the front page was changed.

hi.in this hour i've monitored the ftp logs and there aren't strange access.i think that the shell attack from one of the user that have the ftp access is the right reason, but there aren't file in the folder with strange name.is possible that the code is inside some common phpnuke file?thanks for reply

Could it be another site on a shared server being attacked by the shell script causing the problem?

I´ve found this very helpful:

However, its good you didn´t find this file on your server. Check the logs in the next time too. Maybe you can find some other interesting things and make sure everything is up-to-date. Also with a Nuke site you should always be prepared to restore your site.
