Will this work with malicious tags as well? I.e. tags that are designed to not communicate with a given phone but with other devices nearby? Can that be detected? My understanding is that regular tags will communicate with all phones, but maybe there’s a way to differentiate who to respond to or change identity for every ping? Not familiar with the exact protocol but basically many different tags near a phone wouldn’t trigger the warning, so if a tag can produce multiple identifiers that the adversary controls it could still evade detection?
