Probing for Passwords -- Privacy Implications of SSIDs in Probe Requests. (arXiv:2206.03745v2 [cs.CR] UPDATED)

Probe requests help mobile devices discover active Wi-Fi networks. They often
contain a multitude of data that can be used to identify and track devices and
thereby their users. The past years have been a cat-and-mouse game of improving
