This. Just, this.

@neurovagrant @cstross @unknownbinaries Woah! Anyone able to find a source in Europe?

[woozle@toot.cat]

@Angle @cstross Are there phones that will do that automatically? The most I've ever seen is where the camera automatically detects and interprets the QR code, but if it's a URL you have to tap on it in order to actually point a browser at it.

@cstross Every time I see something like this I think to myself, Monty Python‘s “The Killer Joke” seemed like such a silly idea at the time…

@neurovagrant @cstross @unknownbinaries I wish that provoked something stupider than a web search, though.

BTW please enjoy:

@anotherdaniel @neurovagrant @cstross @unknownbinaries could probably make one on any online print shop...as long as their systems don't try to read the QR code and then quarantine themselves!

[trainguyrom@techhub.social]

@nblr @cstross I'm guessing that's the pattern of yellow dots on US Currency to prevent scanning it?

[imsop@tech.lgbt]

@cstross I can't think how to search for it now, but I remember reading a while back someone went to a convention wearing makeup designed to defeat autofocus algorithms, and watched people frowning as they tried to take photos of it.

@cstross Shades of William Gibson's "Ugly t-shirt" from Zero History. Papers were written...

@cstross Max Gladstone wrote something similar in Empress of Forever... QR code face paint to hack a security camera

[scurra@mastodon.social]

@cstross I'm now wearing a badge on my coat that is a QR code which links to a page on my personal website that (currently) says "by photographing/filming me without permission, you agree to pay me an appearance fee of £100." It's obviously an empty threat, but hey, I felt like I needed to do something.

@neurovagrant @cstross @unknownbinaries How big a zip bomb can you get in one, anyway? And can you fit the EICAR string in an unpleasantly long way in?...

[spiritualtechie@weirder.earth]

@moira @cstross Use a traditional camera for recording at that point. But then again given how good some cameras are for zooming, that should always be the option.

[werebooks@mastodon.social]

@cstross It's ironic that an idea from an earlier, more innocent era has caught on now that no sane person would blindly go to an obscured URL.

[klassika@mastodon.social]

@cstross
Reminds me of https://www.wired.com/2011/10/qr-malware-arrives/

[gerardthornley@hachyderm.io]

@nblr @cstross That's a shame. I've been meaning to make one of those for years.

@trainguyrom @nblr @cstross
Not just America.

[meltedcheese@c.im]

@cstross Brilliant

[radiocarbann@mastodon.social]

@cstross yeah but then the ICE Gestapo would start wearing them

[midgephoto@photog.social]

@Scurra@mastodon.social @cstross
Which jurisdiction?
