NFC Copy Cat

NFC Copy Cat, manufactured by Electronic Cats, is a small device that combines two powerful cybersecurity tools, NFCopy and MagSpoof. NFCopy works by reading or emulating an NFC card; depending on the necessities of the researcher. On the other hand, MagSpoof can wirelessly emulate/spoof any magnetic stripe card. So using NFC Copy Cat, the user will have a device capable of storing magnetic stripe data or NFC payment data to be replayed later — known in the cybersecurity world as a replay attack. 

To show the capabilities of NFC Copy Cat, the emulation example will use a Visa MSD protocol. So be aware that this type of transaction will not be accepted in some payment systems.

NFC Copy Cat combines a simple user interface that can be programmed using Arduino IDE. Adding a micro USB connection, 3.7V LiPo battery connector, antenna, two programmable buttons, LEDs and a reset button. The most important part, NFC Copy Cat is an open hardware project. So anyone could modify or redesign it on their own.

Devices like NFC Copy Cat are essential for researchers, students, teachers or anyone interested in payment systems. It will help to understand how the payment system works, the communications or the APDU protocol. 

Some of the code examples that will be available introduce different concepts. For example, how to detect a card reader, how to detect an NFC card, how to use MagSpoof using a button as a trigger to spoof, how to use NFC with a button to emulate, how to read a Visa card, how to emulate a Visa MSD card, how to generate challenges to extract card information or how to combine both tools: NFCopy and MagSpoof.

nfc-copy-cat's Issues

Hardware setup imformation

Hey can you send some info on how to hook up and program the board with arduino mega 2560. Also any pictures and basic hardware/hookup support would be appreciated.

Instructions to connect and setup

It will be nice if the wiki page is updatd with the details to setup the connection of NFC Copy Cat with NFC Module for the Begineers and student like me to follow through the examples. Appriciate the samples in the repo.

Is there a program or tutorial to decode the nfc tag data or msd data?

Is there any tutorials of sites with more info on decrypting nfc data and converting it to magstripe data. My main question is why is Magstripe data so important? How did Samy Kamkar figure out what parts of track 2 discretionary data needed to be changed in order to downgrade the service code from 201 to 101. Was his downgrade method simply using his algorithim to use a previous cards CVC3 or CVV2 on the magstripe and apply it to the new card?

Being helped by support, thank you

Help with PDOL challenge

Hello,

I’ve recently gotten a nfc copy cat and am struggling to understand how to run the read_replay_spoof .ino

could someone please clarify what “ Make a right format challenge using the card PDOL to extract more data(track 2)” means? And how I should go editing the ino?

ive successfully got my cards pdol with the acr122 and cardpeek what next?

bootloader

NFC Copy Cat is an interesting project. I made several PCBs. How can I burn the bootloader?
