Sorry, but right now, that news story is totally unproven. I'm not even sure why it's getting reported everywhere.
According to Stevens, the credit card data is up on illegal forums and holds enough information for anyone wielding it to siphon money off the card holder. Although Stevens didn't provide a link to these forums for obvious reasons, he claims the credit card data peddled there includes card holder's names, addresses, phone numbers, email addresses, dates of birth and also the CVV2 numbers.
EDIT: from the man himself

So a guy saw something, somewhere that could possibly be or may not be...
