Right now, using curl, [ķ]eepass.info redirects to xn--eepass-vbb.info and consequently that redirects to official domain keepass.info.

Those questionable websites often do redirection to a legit site like Google unless certain condition is met. For example, it could detect and only lead the user to the fake site if the user is coming from the ad. It's a common technique for them to avoid getting caught.
