The best use of QR codes

[tommysoda@lemmy.world]

I want a shirt that has a QR code that Rick rolls people.

All fun and games until you open your camera app and it's in selfie mode, instantly catching the QR code and bricks your own phone.

Not all Phones habe qr code detection in the camera mode

[bleistift2@sopuli.xyz]

I believe this should work. At least some German emergency vehicles now come with filming protection.

The linked web page reads, “Attention! Rubbernecking kills!”

[psythik@lemmy.world]

That makes no sense, cause why would you intentionally click on the link you inadvertently scanned to brick your own phone?

[blackn1ght@feddit.uk]

Because people are idiots and like to press buttons.

Wait until somebody actually makes brain implants!

But on the other hand, people have actively used memetic hazards for millennia. Want to star a nice, cozy witch hunt?

Strongly reminds me of Old MacDonald Had a Barcode, E-I-E-I CAR. Basically put a standard anti-virus test string into various sorts of barcode and see what breaks.

I'm not sure a pseudo QR code on the truck gives off the right message

I actually would really like to know, what it says and would make myself punishable by that
But I think, it looks so inviting to scan it...

Ah, the Basilisk Hack.

Wasn’t this almost the plot line of Snowcrash?

[easternlettuce@lemm.ee]

Name one released in the last five years that doesn’t

[jolteon@lemmy.zip]

I can't think of a single phone that automatically opens links that are in QR codes. The worst it would do is just show a link to malware, wish you would have to manually click in order to download the malware.

[tacosanonymous@lemm.ee]

Every smartphone I’ve had does but every one of them has also asked if I want to follow the link rather than just doing it.

[astralpath@lemmy.ca]

Is this theoretically possible?

[granitem@lemmy.world]

Getting closer to Snow Crash all the time.

[driving_crooner@lemmy.eco.br]

AIs need to read it, so it could be a way to inject prompts on AI models.

[craigers@lemmy.world]

Modern Day Medusa sounds like a cool band name

[littlewonder@lemmy.world]

Most do. It's the only reason they finally somewhat caught on after a rough start when users had to download an app in order to read the code.

[bugkilla@lemmy.world]

Well, yes. You could bury code or malicious data in an image, QR or otherwise, and leverage an exploit that during processing of the visual data within the camera subsystem or inter subsystem calls could hypothetically trigger an execution path that results in a different outcome than expected, all without user permission. There is a lot of sw and hw sec controls in play at internal system boundaries and it would be very very difficult to gain privilege enough to fist fuck a phone but not impossible.

With the outstanding level of FR, NFR and Sec testing that companies perform these days it is not likely to happen. It's not like they push out minimal viable products or something, right? /S
