How it takes just six seconds to hack a credit card

Mohammed explains: "Most hackers will have got hold of valid card numbers as a starting point but even without that it's relatively easy to generate variations of card numbers and automatically send them out across numerous websites to validate them.

"The next step is the expiry date. Banks typically issue cards that are valid for 60 months so guessing the date takes at most 60 attempts.

"The CVV is your last barrier and theoretically only the card holder has that piece of information — it isn't stored anywhere else.

"But guessing this three-digit number takes fewer than 1,000 attempts. Spread this out over 1,000 websites and one will come back verified within a couple of seconds. And there you have it — all the data you need to hack the account."

Никогда бы не подумал, что кредитные карты взламывают методом перебора, причем за считанные секунды.
