Millions of NFC Mifare Classic cards are used for public transport, access control and other purposes. These NFC tags use encryption so that the data on NFC tag cannot be read or changed by someone who scans the tag without … Continue reading Can we capture security key used in an NFC connection for Mifare Classic?
I have an NFC/RFID keychain that looks pretty much like this one:
When I read it with an Android app called “Nfc Reader”, it shows me a specific ID (always the same) and it says that these technologies are used: IsoDep, NfcA, NdefFormat… Continue reading Is it possible to clone an NFC/RFID chip that uses IsoDep, NfcA and NdefFormatable
The report comprises two papers in which we analyze all existing methods of authentication used in ATMs and those expected to be used in the near future, including: contactless authentication through NFC, one-time password authentication and biometric authentication systems, as well as potential vectors of attacks using malware, through to network attacks and attacks on hardware components.

MIT Media Lab and Microsoft have teamed up to take wearable devices one step further — they’ve glued the devices directly to the user’s skin. DuoSkin is a temporary tattoo created with gold leaf. Metallic “Flash” temporary fashion tattoos have become quite popular recently, so this builds on the trend. What the team has done is to use them to create user interfaces for wearable electronic devices.
Generally speaking, gold leaf is incredibly fragile. In this process to yield the cleanest looking leaf the gold is not actually cut. Instead, the temporary tattoo film and backer are cut on a …read more

I’m reading about NFC and how its security can be enhanced. I read somewhere that it is possible to use TLS over NFC. Unfortunately, I can’t find any more information on that topic.
How does TLS over NFC works ? Is it someth… Continue reading How does TLS over NFC works?
Everywhere a question like this is asked, I see people responding that (in a scenario where a card is used) the card does some processing with the data it receives/generates some data when it receives a signal. How is this po… Continue reading How can RFID/NFC tags not be cloned when they are passive technology?
Near Field Communication (NFC) is something we take for granted these days. Nearly all smartphones have it. We even have NFC interfaces for all our favorite development boards. NFC’s history goes back all the way to 1997, when an early version was used in Star Wars special edition toys. Radio Frequency Identification (RFID), which NFC builds on, goes back even further. The patent citation trail leads all the way back to 1983 in a patent awarded to [Charles Walton]. NFC is much more than RFID though. The idea of two way communication between devices opens up tons of possibilities for …read more
I have a bank account that I never use, someone cloned my debit card and used it to buy something in Brazil in order to make sure the cloning was successful then they started making transactions of £10 till they sucked everything in the a… Continue reading Is it possible to clone my contactless debit card while it’s in my pocket?
I’m attempting to do some RFID and NFC cloning and replaying research, as I’m hoping to be able to demo physical security as an attack vector to a few of out clients and prospects.
The downside (ironically) is that from what… Continue reading What is the current state of RFID / NFC security?
I saw a few threads about NFC NTAG against cloning and NTAG Desfire, I just want to find out if NTAG 21x with their “New” password protection and “Original Signature against cloning” really does provide the security against it(the cloning … Continue reading NXP NTAG 21x/Desfire password protection and Original signature, protects against cloning?
