Abnormal Google Site Verification - Joomla! Forum - community, help and support

hi,

i had verified site @ goole file "google14bdc5fc69cc4c00.html" on site.
the file still on site , able verify site.

but site responds call www.mysite.com/google........html format.
in fact should respond :

www.mysite.com/google14bdc5fc69cc4c00.html

but responds call like:

www.mysite.com/google1234567890.html


i don't know causes security breach.
anybody can register site , verify now.
how can prevent ?

thanks.

it responding 404 header though, , not 200 header. there many tools check http responses, check http response , post here if getting 200 on random links instead of 404.
