I went to check on my hosting site that I am working on getting up. And was shocked to see this: ( Check the site ) http://buynethosting.com/billing/ WHMCS was hacked by a group of Iranians. Anyone know how this may have happened?. How I can stop this from happening again and How I can fix this?
Did you implement any of these additional security steps for your WHMCS installation? http://wiki.whmcs.com/Furthur_Security_Steps
I just found out what they had done. And my friend fixed it. They had found an editable file and loaded it will all their crap.
Probably any file with Chmod 0777 when Apache's running as something like DSO or lower if you are running suexec/suPHP. Jay
