I run a website at https://fastslots.co. I just discovered that I am getting requests from the URL https://canadaehtees.com/ that I have no affiliation with. When I load canadaehtees.com in my browser I get a warning about an invalid SSL certificate. If I proceed anyway, the site that is displayed looks and behaves exactly like fastslots.co and all requests made there go to my server. However, the URL stays at canadaehtees.com.
My site is written in Node.js, and I am not using a proxy. I am redirecting all requests that use HTTP or that start with www to my site using HTTPS.
I am not sure what the best thing to do is. Obviously I can just return an error page if I get a request where the URL does not match fastslots.co. Still I am worried about what is going on here. Does anyone know?
[Edit: I am now redirecting all requests to fastslots.co that have an unknown host (such as canadaehtees.com for example). Is this not a good idea?]
