New security flaw in credit card chips revealed

Another reason to use cash when you can.

 

These chip cards are useless in an age where many people buy things online and all the card detail, often including the CVS code, get placed on another computer system... Uhhh. Hello?

 

Thanks, Mark. Do you know of a way to avoid using a chip card at a location that insists on it? Thx

 

Also, sorry, I forgot, just how does the magnetic code rewrite happen? How do the bad guys do it? How do they get access to that strip, from the reader?

 

The strip is just a piece of cassette. Like how they storage music but instead an audio file of your information. And yes it does play a sound if u take the strip and play it on a cassette player.
Basic audio change to digital, just like how 56k Internet work, if u pick up the phone while someone was on the internet, it make a werid sounds.

So basically hackers and take that sound bit and just make a new tape and put it on a card. Doesn't even have to be a real card, a square cut out of cardboard could work too..

To access the strip of data, hackers use a card reader that's put on top or in front of a real card reader. For example an atm machine. While you stick your card in, it will read the hacker's card reader first, then the real one secord.



Ita like something like this. Also called card skimmer.

The chip card is encrypted. Making it harder for hackers to steal your information. The link posted only show the flaw of the magnetic strip, and how it can still be hack and make the card reader thinks that swiping the card is the only way.

Europe had this technology a long time ago. They already switch over making the United states the last big economic country to apply the chip card.

 

Also squeaking out what I know of computers, these cards generate a one time key which is a number that is about 255 characters long. once the chip generated this key it literally asks the Master server (Your card issuer) if they have a same key number for that specific transaction taking place now.

If both agree, then it's approved and that is discarded never to be used again electronically. The large number key.

I like them. But I keep them in Faraday cages now because some of the newer cards have ears inside and want to communicate with nearby devices that have ears also.

You can literally buy a laptop, put that in your backpack, and a 60 dollar sensor that will have you walk down say a cafeteria line inside a truckstop or a College eating place and harvest the cards off those which are calling for communication with other towers and devices to make a sale.

But you wont have that key and chances are you cannot use it.

There was a ... hack not long ago where Apple Phones uses a Infrared Heat Sensor on the camera lens so you hover over the keypad of the cash register in the walmart and notice via temperature differences in time the 4 digit pin of the person in front of you.

This is why I place my palm over the entire keypad to essentially heat it all up a moment and destroy any chance of harvesting the pin off me this way....

 

If you have a chip enabled card, you should use it where offered. The chip is still superior to the magnetic stripe.

This article makes some broad assumptions.

It is true that the implementation of chip-based cards has been haphazard at best.

Most US card issuers aren't requiring a PIN as part of the implementation of chipped cards either as the UK did.
