block a root domain from refering to a page under my domain?

While looking through analytics data I found a root domain pointing to a page under my domain. Here it is:

The real page: http://sightofnic开发者_如何学运维k.com/phone/

The fake page: http://danielitollamar.tk

How do I stop this redirect or whatever it is?

It's just a frame. You can try a frame-buster, but they may break out a frame-buster-buster

A possible server-side solution is setting the new X-Frame-Options response header to SAMEORIGIN. However, this is only supported in recent browsers.
