Given just the domain name and the knowledge that a public website with that address is hosted on AWS (by means of the IP address etc.), is there anyway of finding out any information about who is responsible for administering that site, i.e. whose AWS account it is?
Due to privacy reasons Amazon will not under any circumstances give out customer information like that even if you can demonstrate that the site is under your control. You could attempt to contact Amazon and ask them to forward an email from you to the account holder requesting that he make contact with you but i sincerely doubt that they will do that.
