Chaff Box

  • An app to confuse wifi MAC trackers by picking up announced MAC addresses from passing phones, then spoofing a list of those MAC addresses in AP polling packets, ruining the location tracking.
  • Multiple Chaff Boxes will tend to exchange MAC addresses, spreading the confusion.
  • A Raspberry PiZW could do it with a patch for monitor mode, but a phone app would be more useful.
