This. Just, this.

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

Not just America.

@cstross Brilliant

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

@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:

@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

[nblr@chaos.social]

@mbirth @cstross We tried. To no avail. Will have to try another iteration with an endless pattern fabric/print. So it is presented in multiple and different orientations.

@cstross AI data centers are this at scale. Only, they are reducing the whole planet to a useless brick.

@cstross it should be called the Medusa virus.

Bonus points for bricking facial-recognition cameras.

@neurovagrant @cstross @unknownbinaries anyone nosey enough to scan it deserves all they get

[stevendbrewer@wandering.shop]

@cstross just remember not to take any selfies, amirite?

[ireneista@adhd.irenes.space]

@cstross oh, but this exists. someone on here did a small batch of sew-on patches a few years ago that were QR codes of the EICAR test file. we have a couple...

[ireneista@adhd.irenes.space]

@cstross it isn't technically a virus, it's a file that virus scanners per their spec are supposed to treat as if it's a virus. so, for example, if a badly-written surveillance camera decodes the QR code and stores it in a way that a virus scanner can see (which is not what it should do, but...), then the virus scanner will quarantine the file which may break the camera

@flippac @neurovagrant @cstross @unknownbinaries if you're executing arbitrary code from a QR code, I think a zip bomb is the least of your worries.

[ireneista@adhd.irenes.space]

@cstross that said, to know whether it actually works and when would require a lot of testing, which to our knowledge nobody has done
