Pleas delete this link asap, its not serving anybody, report this type of things directly to staff.
What’s the point of this, are you seeking public support?
Your probably acting in anger and trying to damage CGtrader but its not serving anyone, except maybe competitors where eventually same things happen. Do not connect to the internet or upload any content to it if you want to avoid getting exposed to its vulnerability's.
What your doing right now is promoting/advertising a pirate website on the public CGtrader forum and while your add it giving them some extra traffic and potentially up-ranking that link above your own payed product in Google so your doing yourself more damage.
Track the source of the link on that website and contact the host with a request to remove the file.
Also keep in mind that in this case the vulnerability that was exploited is probably one in the credit-card payment system.
