The hack and steal information from the chip is supposed to cut down on credit card fraud, and it has to some extent. But CNN's Laurie Seagal found out how it, too, can be hacked when she spoke with employees of a company that aims to protect people and organizations from digital crime chip cards they take forever. On the bright side, they're also more secure. They're supposed to stop criminals from stealing our information. But the very thing that makes them take longer may also make them vulnerable on an old fashioned credit card. The data that's sent to the register s static. It never changes on a chip card. The data's randomized, which means it's only good for one transaction. Normally, information that expires after just a minute would be useless. But if hackers could steal it and use it all before it switches again, they're in business. And new research shows that might actually be possible if hackers can crack open a store register and add something called a skimmer. Maybe they're friends with the cashier. Maybe they own the store themselves. Whatever the case, the hackers wait for you to insert your card and then they're minute begins. Here's how it works. During that minute, the hacked register is stealing all of your cards information and wirelessly transmitting it to another device the hackers have set up elsewhere like a smartphone ready to make a mobile purchase Or in this case, ah, hacked a T m. That's confusing the data for your physical banking card. And first of all, wow, What did we do? See? Can you explain what just went down? The date on the card is getting transmitted to a device that's inside this false front here on that, then in turn, is starting to punch in all the data 20 in the pen, asking for $200 hitting with there's little this'll robot hands that are actually putting the pin numbers. In there. You have the skill that enables you to hack in a team and make money just kind of flow out. Yet you want to use this skill for good. A lot of people wouldn't take the money and run So what is it about you that makes you want to use this power for good?
