My question is: How can the scammer still scan a user's data when the user registers their account on the legitimate site, after being redirected from the fake site?
So, suppose I go to homeaway-eu.com. I'm then redirected to homeaway.com. Now I search for a house and book it, after entering my data. How can the scammer get this information that I entered, such as my payment details and contact infos?
Edit: I think the answers below are coming from the point of view of the question that I linked above. My question is about the supposition that I wrote, not the exact case from Travel StackExchange.
