CC numbers are everywhere

This article from slashdot is very good. It's funny to see how easy it is to obtain credit card numbers. PCI still have a long way on securing this information, if this can be done after all. From the article:

"Some "script kiddie" tricks still work after all: Take the first 8 digits of a standard 16-digit credit card number. Search for them on Google in "nnnn nnnn" form. Since the 8-digit prefix of a given card number is often shared with many other cards, about 1/4 of credit card numbers in my random test, turned up pages that included other credit card numbers, and about 1 in 10 turned up a "treasure trove" of card numbers that were exposed through someone's sloppily written Web app. If the numbers were displayed along with people's names and phone numbers, sometimes I would call the users to tell them that I'd found their cards on the Internet, and many of them said that the cards were still active and that this was the first they'd heard that the numbers had been compromised."
