Might be just my public education, but I don’t get it.
How SLOW does one have to drive to ‘...accidentally collected emails and other personal data...’
Even in my area, where there exists multiple SSIDs (all secure, so the little icon says), taking the strongest signal available; you’re still talking seconds to ‘handshake’, more still to snoop and more still to receive...all at the end/edge of these connections/from the street/etc before the signal drops ala range??
They just capture random packets that could have anything in them as they pass by. Those random packets are likely stored on a hard drive along with the GPS location and processed at a later point to try to extract the SSID and whether it is encrypted or not.
So that captured packet could well have “personal” information in it which is what this uproar is about.
I get the sense that this is from wide open connections. Everybody on your street is smart about it or has a newer router which encourages encryption.
