This guy was able to fit an entire snake game on a QR code. The QR bar
contains the whole game code compiled to a machine code which decodes
into an executable (it's NOT just some kind of high level interpreted
code that would rely on code hidden in the interpreter).

This means that you could actually fit an entire malware code on a QR
bar as well, not just link to it.

They have putting malware in qr codes forever now, it's even apart of
S.E.T. for years now.

How much you can do probably depends on quality of the camera on a
device.  Couldn't there be a way around this such as make a QR code
reader not respond to those kind of requests by stopping the scanning
once it realizes what type of data is in the QR code?

You need an AV database, and then maybe if you're luckey it'll
possibly find it.

but is it effective though? it seems like qr code readers are pretty
safe, at least the smartphone ones

That's one way but I was talking about blocking out anything that
isn't just a link, phone number, or email address.

As one guy at defcon said (I don;t remember who): go to an area of
your city that's full of hipsters and place a malicious qr, you'll get
thousands of hits

What about placing something non malicious just a hit counter and find
out?
