It’s not really that simple, and it’s likely that these attacks would fail CVV/3DS/etc, so it’d be hard for a reasonable merchant to be tricked regardless.

- tyingq 4y ago"I also determined that the CSC (essentially behaves like a CID or CVV2 on the magstripe) for a lost or stolen card continues to work for a newer, predicted card. An attacker would be able to use a stolen card's CSC with the predicted card number and expiration to make actual purchases." Also...ask any merchant if they've ever NOT been left holding the bag for a fraudulent purchase. The only time that happened for me was when I could prove it was fraud by the actual cardholder, and even then, the banks would often deny the counterclaim anyway.
