Working out the card number, expiry date and security code of any Visa credit or debit card can take as little as six seconds and uses nothing more than guesswork, new research has shown.

Exposing the flaws in the VISA payment system, the team from Newcastle University, UK, found neither the network nor the banks were able to detect attackers making multiple, invalid attempts to get payment card data. By automatically and systematically generating different variations of the cards security data and firing it at multiple websites, within seconds hackers are able to get a 'hit' and verify all the necessary security data.

Investigators believe this guessing attack method is likely to have been used in the recent Tesco cyberattack which the Newcastle team describe as "frighteningly easy if you have a laptop and an internet connection. And they say the risk is greatest at this time of year when so many of us are purchasing Christmas presents online. This allows unlimited guesses on each card data field, using up to the allowed number of attempts - typically 10 or 20 guesses - on each website.

This means it's quite easy to build up the information and piece it together like a jigsaw. If the hits are spread across enough websites then a positive response to each question can be received within two seconds - just like any online payment. To obtain card details, the attack uses online payment websites to guess the data and the reply to the transaction will confirm whether or not the guess was right.

Because the current online system does not detect multiple invalid payment requests on the same card from different websites, unlimited guesses can be made by distributing the guesses over many websites. At the same time, because different online merchants ask for different information, it allows the guessing attack to obtain the information one field at a time. 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.

Banks typically issue cards that are valid for 60 months so guessing the date takes at most 60 attempts. Spread this out over 1, 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. An online payment - or "card not present" transaction - is dependent on the customer providing data that only the owner of the card could know. But unless all merchants ask for the same information then, says the team, jigsaw identification across websites is simple. For example, use just one card for online payments and keep the spending limit on that account as low as possible. In data breach situations, credit card companies generally offer affected customers fraud monitoring services at no cost -- and customers aren't on the hook for any fraudulent charges.

Someone further up the chain -- the card issuer, or sometimes the merchant -- is responsible for those costs. The Cybercrime Economy. Print Comment. Did Apple save Dr. Dre and Jimmy Iovine just in time? How to make good TV for the web, according to Amazon. Tech Jobs. See all jobs.
