Re: QR codes as an attack vector anyone?
At my local* beach they have removed all the QR codes to avoid the 'risk' of miscreants overlaying dodgy QR Codes on the posters.
So now we have people walking up to the Ticket Machine, reading the URL off the poster and 'switching off all external sensors while trying to complete the 'Parking App' process'.
This means that the Ticket machine is blocked by people (plural) tapping away on their phone, completely oblivious to the people who are trying to get close enough to the Ticket machine to actually use it by swiping their 'National Trust' card. !!!
Literally, the people walk up to the Ticket machine, read the URL and stop dead wherever they are standing, usually within 2 feet of the machine Display then 'flat lining' while they use the 'Parking App' !!!
This is young & old alike ... a complete lack of thought for anyone else who has just parked and is trying to be law abiding by getting a parking Ticket/voucher.
