r/HowToHack on Reddit: Can automatic credit card verification, where it checks before you even submit, be exploited?
May 11, 2024 -
I guess the question simplified is: can you do anything with just a cc number?
I assume I'm missing something obvious here. For example, I was ordering food online and when I went the website it would automatically check if the credit card number was valid or invalid as soon as you typed the last character. No cooldown.
I even messed around with it for a bit and ended up putting in random numbers and got a match. Is getting the name, cvv, etc nearly impossible without more information? Is the credit card number too large to keep checking it that way?

There isn't really anything to exploit. The numbers just have to match the algorithm. There are an unlimited number of credit card number generators online that can be used to generate mathematically valid numbers. The actual verification occurs when you submit the form and the service attempts to make payment. The chance that you can guess, or generate a CC number that is actually active, as well as the cards CVV number, valid expiry date for the card and actually have it work first time is virtually impossible. The number of combinations of date and CVV for a single CC number would be in the billions. It would take forever to cycle through them all on a payment service. Just to discover the card number wasn't active, and you start again with the next one. Was a different story back in the 90's though. Not all payment services were instant, so websites would accept payment so long as the CC number matched the algorithm. Generating numbers was an easy way to get software licences as the licence would be sent out almost straight away. By the time they got around to manually processing it, it was too late. Offline licensing was very common back then. So nothing they could do to stop you from using it.
