Back in early Google days...2000-2008ish, all you needed to do is type VISA*00000000 and lists of CC#'s with all the details of cardholder.
Don't try to Google your own CC# or the method above, Google WILL red flag your IP than contact your ISP and knock knock.
I remember Googling my CC# and my info came up, called the CC Company and they crapped themselves...it's numbers people, loopholes/backdoors will always be open...online shopping will never be secured nor will your personal information.

The search request was simple. Using a researcher's Visa debit card, we started with the first four numbers on the card and extended the span of possible number combinations. So we entered in the google.com search window: visa 4060000000000000..4060999999999999.
The result was a long list of Visa card numbers complete with name, address, phone number, expiration dates and a list of recent purchases. In less than two seconds, we found everything a cyber crook would need for one heck of a shopping spree or a fresh new identity.
