Ok dude.Check your site.
The most sensible bug was that the catalog /admin had not been
protected from the remote access, but you have already fixed it.
Also, please check http://arizonamodeler.com/catalog/account.php file.
I have encrypted shell in it.
By the way, use another Shop, because the current one has too many
vulnerabilities! And check the updates on http://www.securityfocus.
com and/or http://www.securitylab.ru
I hope that you are not offended.
Contact me if you need any help.
Thank you
