my website has been hacked several times. The informations from hosting said the mass spam e-mails were being sent from my account through different script every time. And one is point into fishing site.
I was asked to secure all mailing scripts to prevent any exploitation by cross scripting hacks to avoid unwanted mail being sent from your account and remove the offended script which is sending spam emails. Also, upgrade the PHP script to the latest version and change the password of your account to the strong value.
I would like find a specilist of Oscommerce to help me with this.
