Hacking master card

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.

If it's a bank card then keep ready funds to a minimum and transfer over money as you need it.

We wanted to show what we are capable of! It's like home Wi-Fi. If you buy a home Wi-Fi router, it's up to you to change the default passcode. Retailers should be securing their own machines.

And machine resellers should be helping them do it. Trustwave, which helps protect retailers from hackers, said that keeping credit card machines safe is low on a store's list of priorities. This problem reinforces the conclusion made in a recent Verizon cybersecurity report: that retailers get hacked because they're lazy. The default password thing is a serious issue. Retail computer networks get exposed to computer viruses all the time. Consider one case Henderson investigated recently.

A nasty keystroke-logging spy software ended up on the computer a store uses to process credit card transactions. It turns out employees had rigged it to play a pirated version of Guitar Hero, and accidentally downloaded the malware.
