New Device Sold On The Dark Web Can Clone Up To 15 Contactless Cards Per Second (softpedia.com) 193
An anonymous reader writes from a report via Softpedia: "A criminal group going under the name of The CC Buddies is selling a hi-tech device on the Dark Web that's capable of copying details from contactless debit cards if held as close as eight centimeters away from a victim's card," reports Softpedia. The device, named Contactless Infusion X5, is extremely dangerous because it can copy up to 15 bank cards per second, something that may come in handy if a crook is going through a crowd at a concert or through a crowded subway cart. The device can collect data such as the card's number and expiration date. If the debit card's RFID chip stores information such as the card holder's name, home address, and a mini statement, X5 can steal that data as well. The X5 is sold on the Dark Web for only 1.2 Bitcoin (~$825), and its creators say that each buyer will receive the X5 device, a USB cable for charging and data transfers, and 20 blank plastic cards.

Well, what really happens is this.
When you read the card, you get the card number and expiry date. It's not good enough to actually do a chip/contact payment, but the information is enough to do a swipe transaction. If you can print a card, and have an old enough store that still uses a mechanical imprinter (the big thing that you put the card in, a slip and slide the slider back and forth that imprints the slip). Or of course, you use it for online shopping.
What happens then is up to the merchant and hits bank - if the bank is smart, they will realize the card used supports chip or contactless, and the terminal supports it, and rejects the transation wanting a chip or contactless.
Online stores and even in-person transactions often require the CVV if you swipe them, as well. (The CVV value is not stored on chip or in the magstripe - it's designed to verify that you have physical access to the card).
Actual payments require a challenge-response - the chip contains a secret only known to it and the bank which never leaves the card.
So you likely can use it for a few transactions which still do swipes and don't check CVVs, but that's about it.

All of the previous chips have so far been cracked after researchers studied the chip, and reverse engineered the encryption algorithm, which are then studied by cryptographers.
A huge part of the security is that no one except one company, actually knows the encryption algorithm and it's extremely difficult for anyone to figure it out, as they would have to somehow view and reverse engineer the silicon circuit by physical inspection.

Maybe. Maybe not.
Remember that these chips are extremely low power low speed.
They have to perform usually a cryptograhic hash of some input they are passed with their secret key. The algorithm used is not a fully secure algorithm like what would be used in https, it's not NIST approved etc. They are custom algorithms designed to be done by a very simple processor very quickly and are orders of magnitude easier than AES or SHA.
Incorrect. Card cryptograms are generated with either 3DES or AES. You can see full details here: https://www.emvco.com/specific... [emvco.com]. Specifically, you want to look at Annex A of EMV 4.3, Book 2, "Security and Key Management".
Note that many of the card issuing networks define their own variations on the EMV specifications, but they all comply with the general framework, algorithms, etc.
As for the nature of the processors, most contactless smart card chips today are 32-bit CPUs running at around 40 Mhz, w

To top that off, many modern security-oriented chips implement HMAC and AES in hardware, which uses even less power and is orders of magnitude faster still. Doing one complete round of AES3 takes thousands of cycles on a CPU but can be collapsed into a single step process in hardware using a fraction of the silicon of a 32bits CPU.

I actually mentioned the coprocessors :-)
Though... I'm not aware of any devices that have HMAC-SHA256 or similar in a coprocessor. That's part of the reason why many protocols use AES or 3DES for what amounts to hashing, because it's much, much faster.

"RFID/NFC blocking" wallets are all the rage these days. That is a far bigger scam than this product, which is simply far too late. The only contactless payment method I have is my phone now, after my last contactless card expired a few years ago. I haven't seen a PayPass or payWave card in years, but average people see the chip in their card and believe it doesn't require contact for some reason (My parents and some older doctors I know went full on tinfoil hat when they first got them before I corrected t

From the VISA Website "If your card is lost or stolen you should notify your bank as soon as possible. If anyone has fraudulently used your contactless card to make a payment, providing you take reasonable precautions to protect your card and let your bank know as soon as you realise it’s gone, you will not be responsible for any losses incurred (subject to your bank’s terms and conditions)."
In other words you are not responsible for any losses. Provided you report it lost as soon as you realis

Is there some reason we're now using this term? Maybe it's just me, but it really sounds entirely Hollywood.
Can we just say internet? Or web?
What we're seeing around here (Score:2)
Around here we have people that will walk into a mall with a scanner and just stick it on peoples wallet pocket or purse. When security is alerted, they just leave. Security says they weren't doing anything illegal.
As far as I know, any US vendor taking a fraudulent swipe or imprint transaction owns the loss as the bank/cc company won't stand behind a non chip transaction. This scanner won't help anyone make a chipped card. Its rare to have information like the card holders name be accessible in this ma

How can you arrange 15 cards on every second within a 8 cm radius?
When cell phones first came with Bluetooth, security required one to disable it.
It was possible to sit in a busy area of a mall and collect all the contacts of those with enabled bluetooth.
15 cards every second within a 8 cm radius, one would surely come across as supisious of doing something dubious.

it's impossible to read the secret keys over any interface of the card. So those cloning devices at most is reading what normally a contactless terminal can read from a card. meaning those cloned cards will fail all the offline and online CAM (card authentication method) since none of the relevant keys (ICC Private Key, nor the Application Cryptogram secret key) can be read.
Unlike traditional magnetic stripe cards, chip cards has robust security build-in, most of the security breach are not from counterfe
