I'd be flattered if someone actually wanted to film me with their phone. :(

[-] Jolteon@lemmy.zip 31 points 1 day ago

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.

[-] smeg@feddit.uk 3 points 20 hours ago

This was a few years ago (so I hope there have been patches since then) but I watched a video which was trying to make an entire game within a QR code: they don't have to just be links, they can be binaries that some devices will immediately run without question!

[-] themoonisacheese@sh.itjust.works 7 points 19 hours ago

Quite the opposite. That video by mattkc (iirc) repeatedly and unequivocally says that to make this work, he made his pc save the binary and explicitly run it using a python script, because doing it natively would be fucking insane

[-] smeg@feddit.uk 1 points 3 hours ago

You're right, I must have been thinking of something else. Happily I can't find any chatter about actual malware in QR codes (it's all redirecting to malicious websites), though obviously there's always the possibility of a new exploit being discovered.

The 3DS used to be hacked using a QR code that was scanned using the game cubic ninja (it used QR codes as a medium for sharing levels). The interpreter had a basic memory safety bug, so you could trigger a ROP chain using a malformed QR code to get ACE. This was of course voluntary by the user (and cubic ninja was hard to get because it was not a commercial success) but that qualifies, I guess.

Then they found out the 3ds browser uses a WebKit version from 2003 and nowadays you just go to a website lol

ACE on a WiiU is just as easy, at least with the Wii you had to use a game!

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

Modern Day Medusa sounds like a cool band name

[-] bleistift2@sopuli.xyz 51 points 1 day ago

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

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

[-] naeap@sopuli.xyz 14 points 1 day ago

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...

[-] bleistift2@sopuli.xyz 3 points 18 hours ago

The way I see it there are two options:

  1. You’re in a car and driving past that vehicle. If you don’t have your phone ready already, you won’t get it out in time and won’t be able to scan the code. You didn’t read the code and didn’t need to (because you weren’t rubbernecking).

  2. You’re in a car with your phone already out (because you’re expecting a crash) or you’re a pedestrian who takes out their phone to film the crash site. You do read the code and you should see it, because you’re rubbernecking.

[-] naeap@sopuli.xyz 1 points 18 hours ago* (last edited 18 hours ago)

I was more thinking about not driving the car myself, but being driven as a passenger

Although it's obviously a safety issue, when people turn away their focus to checkout a crash - no discussion about that - I was more thinking about the ethical issue of gaffing at injured people

[-] blackn1ght@feddit.uk 35 points 1 day ago

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.

[-] Psythik@lemmy.world 19 points 1 day ago

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

[-] blackn1ght@feddit.uk 21 points 1 day ago

Because people are idiots and like to press buttons.

Finally, we can build memetic hazards in real life

[-] marcos@lemmy.world 8 points 1 day ago

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?

[-] Amputret@lemmy.dbzer0.com 4 points 1 day ago* (last edited 1 day ago)

Ah, the Basilisk Hack.

(Nothing to do with Roko, btw.)

[-] GraniteM@lemmy.world 2 points 1 day ago

Getting closer to Snow Crash all the time.

[-] Anticorp@lemmy.world -1 points 17 hours ago

So... Everything is a meme now? Screenshots of random text posts are memes?

[-] TommySoda@lemmy.world 16 points 1 day ago

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

[-] AstralPath@lemmy.ca 5 points 1 day ago

Is this theoretically possible?

[-] perviouslyiner@lemmy.world 1 points 17 hours ago
[-] ChaoticNeutralCzech@feddit.org 1 points 1 hour ago

So what? That only prevents people from editing the photo in certain programs like Adobe Photoshop.

[-] BugKilla@lemmy.world 7 points 1 day ago

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

[-] kevincox@lemmy.ml 9 points 1 day ago

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.

[-] AtariDump@lemmy.world 3 points 1 day ago

Wasn’t this almost the plot line of Snowcrash?

[-] MIXEDUNIVERS@discuss.tchncs.de 3 points 1 day ago

Not all Phones habe qr code detection in the camera mode

[-] littlewonder@lemmy.world 3 points 1 day ago

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.

[-] tacosanonymous@lemm.ee 3 points 1 day ago

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.

[-] EasternLettuce@lemm.ee 2 points 1 day ago

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

[-] MIXEDUNIVERS@discuss.tchncs.de 0 points 23 hours ago

Idk I use a Pixel with GrapheneOS Camera App

[-] TheOakTree@lemm.ee 3 points 17 hours ago* (last edited 17 hours ago)

That's custom software on custom firmware, which is very extraneous to the average consumer...

It's also not a "released" phone in the sense that Google isn't selling it in that state.

[-] FaceDeer@fedia.io 1 points 1 day ago

And those that do don't download and run code willy-nilly.
