Sounds like a pretty easy way to do a denial-of-service attack against a grocery store if you can just shut down a bunch of terminals with a barcode. I guess you'll stand out a fair bit if you move from PoS to PoS, scanning a barcode.

- flerchin 5y agoI suppose it would be considered vandalism. "but i just scanned a barcode" will not amuse the judge.

See: https://en.wikipedia.org/wiki/EICAR_test_file https://en.wikipedia.org/wiki/EICAR_test_file and this video https://www.youtube.com/watch?v=cIcbAMO6sxo https://www.youtube.com/watch?v=cIcbAMO6sxo where all the gates at a parking garage are rendered inoperable because someone scanned a QR code that encoded EICAR

- Maursault 5y agoThe barcode register attack was explored in a episode of The X-Files titled Duane Barry (2x05; 14 Oct 1994), when Special Agent Dana Scully scans a chip (that had been found implanted in her neck and subsequently removed) at a grocery store checkout scanner, and iirc all the registers went berserk. So this is definitely a thing.
- copperx 5y agoIt's amusing that you are using an X-Files episode as if it was factually true.
