Not sure if anyone has used these guys for whmcs integrations but I just got this email from them:
Unfortunately earlier this evening it would seem that our account (scriptinstallation.ca) was hacked. The person or persons who did the hacking may have had access to our whmcs support tickets and orders so if you have provided us with FTP access details in the past PLEASE CHANGE THESE IMMEDIATELY if you did not do so after your order.
At this time we do not think the hack was done through whmcs - possible using wordpress which we will no longer be using.
