This. Just, this.

@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?

@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.

@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.

@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?

@mack505 @cstross https://www.johanniter.de/johanniter-unfall-hilfe/gaffen-toetet-ein-design-das-leben-retten-kann/?utm_campaign=gaffen-toetet&utm_content=bg&utm_medium=redirect is the background to the German ambulances with QR code.

[gulfie@mastodonapp.uk]

@neurovagrant @cstross @unknownbinaries I have that as a QR code on the underside of my laptop…

[mainec@fromm.social]

@cstross not a QR code, but human readable. Not a malware, but legal language, so arguably worse than malware:

Refers to German privacy laws related to photographing people.

[voxel@infosec.space]

@cstross Didn't expect to see this again, could you provide the original source?

[heppycat@mastodon.social]

@cstross @stefan an EICAR test code would be a good start
