DEFCON 16: Toying with Barcodes

The airport thing could get you through security, but you would never get on a plane. At the gate they have a list over all the booked passengers and when you scan the ticket barcode the system simply marks your name as boarded. If your name is not on the list, it would tell the gate staff that the scanned name is not on the list. The gate staff will probably check your booking number, but you do not have a valid one, so you will be denied on the plane. Barcodes in this case is mostly used for making the boarding process quicker, in the way that the gate staff don't have to write your boarding number every time. A barcode is useless if the printed information does not match the information in the system.

It's not that the code itself was vulnerable, it's that the code was used to store level data and the level data format was exploitable.

Indeed, I think the vulnerability was kinda similar to what they later did by encoding exploits in very long Unicode names for audio files. Nintendo Audio did not appreciate that.

[@jackkraken3888]

Interesting fact: One of the earliest forms of barcodes were in the shape of a bull's eye. Also the barcode was actually inspired by someone overhearing a conversation of a retail company wanting to find a way to speed up the checkout process , but it would take years for it to be used in retail.

[@error.418]

"One of the earliest forms of barcodes were in the shape of a bull's eye." The guy who invented the first barcodes just thought it would be easier to scan if you could do it in any direction. So he made a linear version and a radial version, which I guess you could say looks like a bullseye. Also, the "bullseye" style code proved to have a serious problem; the printers would sometimes smear ink, rendering the code unreadable in most orientations. However, a linear code was printed in the direction of the stripes, so extra ink would simply makes the code "taller" while remaining readable. So that's why the linear code won in the end.

[@jackkraken3888]

Yes. :)

[@Gunbudder]

Fortunately, my local airport JUST got a new system that links your luggage to your ticket through a network, and not through tthe barcode. In fact, if you don't check a bag, and someone tries to check a bag for you, they will see an error. Vice versa, if you check a bag, then decide you do not want to check after all, they will stop you at the security checkpoint saying you need go either check a bag, or remove the checked bag from your ticket. none of this uses the barcode (finally)

Funny statement about the can recycling... we have deposits for cans here but no machines. The return process is much worse than simply feeding them into a machine. You have to show up when the grocery store is taking returns, place your bottles and cans into a cardboard flat at the grocery store, then an employee counts them, then dumps them into a bin and you get your five cents :/

[@error.418]

that actually sounds much easier... you hand them to someone else who counts them and gives you money. feeding them in one at a time is such a hassle that I would just throw my shit away instead of recycling it.

[@dnb5661]

Where I live, you dump the container into a carousel thing, that lifts containers to the top. It has some sort of system to automatically determine what type of bottle it is. An attendant watches over the machine as you put your containers into it. The attendant manually tallies glass containers.

[@desolderingpump2010]

"...they can make luggage illegal ..." (2011). Now in 2017, you can't bring your laptop ... :P

You can bring it, but it must be scanned separately. Reason is, that it is really hard to distinguish between laptops and bombs, or laptops and laptops with bombs inside them, or batteries in laptops and bombs inside the battery compartment of a laptop. It is a technical limitation of image quality in x-ray scanners.

Hi, I’m from 2020 and I wonder whether at least California is still catching up on the beer bottle recycling

[@marc-andreservant201]

Another possible scam is bottle returns in adjacent jurisdictions: grab non-refund bottles or cans from random garbage bins in the jurisdiction with no bottle return laws, stick on a barcode with a UPC number that does qualify for a refund, then cross the bridge and stick the bottles/cans into the recycling machine. It doesn't matter if the receipt is digitally signed, because the crusher ate a piece of metal shaped like a can with a UPC code for a refundable deposit matching the weight of the empty can, so it will sign off on your cash register slip. This may or may not be fraud, because you took something that was in someone's garbage bin (legal: abandoned property) and sold it to a recycler who will get paid per kilogram on returned cans, so they don't lose money. Also, what may have ended up in a landfill is now being recycled instead. Depending on your jurisdiction, the deposit may be worth more than the metal content (this is the case in Quebec), so they charge you 20¢ extra at the cash register when you buy a full beer can, and then refund the 20¢ when you return an empty beer can. If the metal value is less than 20¢, you are defrauding the government and it would be illegal.

[@TheGoodChap]

UPS uses only MAXICODE. Sometimes our scanners won't be synced to the terminal (terminal computer is attached to a belt we wear and log into, when we scan packages the scanner on our hand sends data to the terminal via bluetooth, the scanner is wifi I think which sends the data to the server). If it's not synced you go to a configuration menu that displays a barcode on the screen we scan to get the two working. It's pretty interesting how it all works, I've always been curious how it all works.

how would you just slip the forged barcode under your 6 pack to get scanned without the cashier noticing? Wouldn't the cashier notice that something was scanned?

Am I missing something here, obviously theyre going to look at the register and be like "oh it says that I owe you money for recycling but i didn't see any recycling barcode paper, where is it?"

[@HenryLoenwind]

The idea is to replace the original product barcode with a fake deposit barcode and not be so greedy that the total of all you buy is weirdly low.

have you ever seen an oral presentation? Was it also filled with angry rhetorical questions? Do you enjoy this style of communication? Is everything, except beer, shit?

[@Maestro-xc4mm]

Is it just me or is he starting out sentences at a normal volume and ending them in a higher tone, kinda like Brian's girlfriend from Family Guy?
