Delta Says Data Exposed for 'Several Hundred Thousand' Customers
Delta Air Lines Inc. said a cyber attack on a contractor potentially exposed the payment information of "several hundred thousand customers."
A data breach from Sept. 26 to Oct. 12 at a company called [24]7.ai allowed unauthorized access to customers' names, address, payment-card information, CVV numbers and expiration dates, Delta said in a statement Thursday. The vendor, which provides online chat services to Delta, notified the carrier and other clients last week.
[...] Delta said it wasn't yet able to say how many customers actually had their data stolen. The information was at risk if a customer entered data manually online to complete a payment transaction, Delta said. Data from customers who used a program called Delta Wallet weren't compromised.

Its a 3 digit number that is easy to get. Oh no doubt they should not keep it. But that is but a minor bump in the road to fraud. The security employed worked well in the dial up days. Now you can have thousands of computer in a bot do your bidding. It is why chip+pin is important. Good thing in the US we just have chip (eye roll).
