What about QR Codes?
Scanning a QR code should never be automatic, think first. QR code capacity can range from 72 to 16,568 bits — more than enough to carry significant information about a malicious instruction for your mobile device, you may think it is just a simple redirect to a website. Nothing is as it seems, hackers and others use this tech as an excellent way to gather user information… it feeds the Digital AI Beast.
Official looking stickers in a retail space or a bank are suspicious enough never mind a crooked sticker at the front of a gas pump or stuck to a table in a resturant? Scan it? That’s a Hard NO. Treating QR codes as you would any other bit of electronic kit is important because that’s exactly what they are: mechanisms for carrying and delivering code to a device.
Random stickers stuck to walls and doors should be treated with suspicion since they’re in far too public a set of locations, even if you could trust QR Codes.
Just because they’re made of ink and paper rather than silicon and gallium arsenide doesn’t mean they’re any less effective — or dangerous.
