If the barcodes are randomised their systems need to have a way to know which barcode is correct as well as a way to randomise the barcodes
Hackers can just exploit that if they get access to it

Bingo. They want the hackers to think they have nothing, when in reality they’re crapping themselves to find the cheapest solution with little media attention. This is another reminder the business worlds focus on ever-increasing market value is a little like autoerotic asphyxiation. Once you start, you know eventually there’s only one way it will end for you.
If an app is used in client side it's relatively easy. They could literally just use the common OTP algorithm, but in reverse. Instead of refreshing ever 30s, set that to like hours or days. instead of generating 6 digits you generate enough for a barcode (like 12 or 13 or whatever is common). On refresh, stuff them in a database, so when a ticket is scanned you can quickly find the corresponding entry and identify it and mark it used.
I have no real idea how you'd do this with printable paper tickets...
I've not been to one of these things, but I'm assuming you have to use your phone tobshow the barcode if it's changing 'every few seconds'. From the description it sounds more akin to something like TOTP, where each person's code is derived from a secret key and the current time. The barcodes aren't random, but mathematically derived and only the current one works. If that is the case the hackers need the secret keys, not the barcodes, and they need to build an app to display the right one at the right time.
If they truly thought it was broken, they could change the process and reissue every single ticket.
It'd take time and effort but it's doable.
Good. I hope this burns their whole empire to the ground.
Among the biggest of asshole scumbags now expect us to believe them? Yeah, those barcodes are 100% legit and they tried to negotiate with those hackers the very second they found out.
