Why can’t a barcode/qr code store an executable virus?
Barcodes, whether one or two dimensional, are rarely used for more than a few hundred bytes. It would be difficult to place malicious code in such a space, and that code would have to exploit a weakness in a particular scanning application, which could be patched relatively quickly.
The Short Answer
Barcodes, whether one or two dimensional, are rarely used for more than a few hundred bytes. It would be difficult to place malicious code in such a space, and that code would have to exploit a weakness in a particular scanning application, which could be patched relatively quickly.
