Everyone,

This morning I received a notice from PayPal that one of our sites got
hacked and was spoofing a PayPal web site. 

When I checked the the site, I was surprised to find they were correct.
About 5 days a go we had a server that got hacked and somehow the file
paypal.com.tar got uploaded to our server and then stored in a a
subdirectory of /var/www/.

I had previously started a mysqld server and planned on using it for web
authorizations.  I had not been able to work on it, but left it in
place.  I looked like the hacker downloaded his paypal spoof files into
a subdirectory of /var/www/phpmyadmin.

I am running 5.3 with all current updates.

I do not have telnet or ftp active on this server, and have password
authentication of sshd turned off.  

I have tried to obtain dialog with PayPal about this but they have not
responded to my queries.  If any of you have had some experience with
this I would be interested in knowing how this may have happened.  I
have shutdown the mysqld server as well as removed access in httpd.conf
of the /var/www/phpmyadmin directory in order to shutdown the spoofing
site.

If any of you have a leg up on this I would appreciate your help.
