Ok first, It's Not a duplicate question My Problem is different.
I recently searched my domain in google like site:mysite.com and I see a load of links to casinos that are not mine. The subdomain structure is www.mysite.com/bellagio
I never created a folder called bellagio and this subdomain(sry I don't know what we call it) is pointing directly to a casino site.
I am using wordpress on godaddy hosting and registered domain there too.
It is something like this question Phishing site uses subdomain that I never registered but not exactly the subdomains.
I tried actually creating a folder named bellagio and then clicking the link but yet it redirects to that spam site.
When I did some research not only me but hundereds on websites were hacked this way.(try searching The Bellagio - Why To Gamble At Bellagio)
I am using free ssl certificates from startssl, is that the cause ?
any help would be greatly appreciated, atleast tell me what and how to check ?
