Generating card numbers that pass the mod10 (Luhn) check is easy. He figured out how to pass the 3 digit code check. Given that it’s only three or four digits, and that plenty of breached cards are available to hackers, it’s probably not super hard to crack.
I suspect that test cards we get from processors work on a lot of production systems, in case you’re interested in starting a career in criminality.
With a big enough training set of cards I wonder if an ML would have any luck with the CVV.
- acidoverride 4y ago3 digit code check can not be cracked, with or without ML. You need other methods to verify if the code is working for a particular card number, most of which require trial(and error) payments. Furthermore, it is plausible that a credit card fraudster keeps notes on, well..., credit cards. Guy could have been old school skimming the card numbers and CVV from purchases at his newspaper stand.
