A few years ago, we saw a project from a few researchers in Germany who built a device to. These contactless smart cards can be found in everything from subway cards to passports, and a tool to investigate and emulate these cards has exceptionally interesting implications. David and Tino, the researchers behind the first iteration of this hardware have been working on an improved version for a few years,.

They’re behind a Kickstarter campaign for the ChameleonMini, a device for NFC security analysis that can also clone and emulate contactless cards. While the original Chameleon smart card emulator could handle many of the contactless smart cards you could throw at it, there at a lot of different contactless protocols. The new card can emulate just about every contactless card that operates on 13.56 MHz. The board itself is mostly a PCB antenna, with the electronics based on an ATXMega128A4U microcontroller. This micro has AES and DES encryption engines, meaning if your contactless card has encryption and you have the cryptographic key, you can emulate that card with this device. They’re also making a more expensive version that also has a built-in reader that makes the ChameleonMini a one-stop card cloning tool. Posted in, Tagged, Post navigation.
Note: I’m not your lawyer, and I’m not giving any official legal advice. Actually, it is only illegal to possess lockpicks in one state (Tennessee) without a locksmith license. In four states lockpicks can be considered evidence of criminal intent, one of those states only if the picks are concealed. Even if they catch you in one of those states where it can be shown as criminal intent, you have a chance to counter prima facie evidence of intent.
The way burglary tools are defined, you could get in trouble with this in many states currently if they can prove intent to commit a crime. Perhaps:. On a regular basis, authentication systems should exchange a token with a carried RFID device, and in subsequent interactions, the list of the last X tokens be returned to the authentication system, so the system knows if it’s the same device that’s been responding. Flag devices whose previous contact transcripts don’t match for enhanced scrutiny.
Allow devices flagged for enhanced scrutiny to be cleared at an authorised/monitored point, at which point it would also update the card to have a new secret/keypair in addition to the old one. Flag attempts with the old key to security (policy on whether access is granted and monitored or denied dependent on security required). The period at which you set the transcript comms + enhanced scrutiny + key change, and how often the person uses the RFID device to authenticate would limit the window of opportunity to use the cloned device. This is slightly more sophisticated. You can log traffic and/or store loads of different cards on one smart card sized device. You can also start doing stuff like random uid and stuff like that.
I think this is overkill if you just want to play around with some basic nfc-fuzzing/public transport stuff – but once you get into the more startling details of how badly designed some of these systems really are – well I think this is the tool for those kinds of details. Also I’m buying one for keeping my dozen cards in one place. This was on my list of things to build and they even got it better than I imagined.
This seems like a completely natural development to me. Even with the highest standard of security, there will be ways to get around it.
Even an 256-bit AES encryption can be brute-forced within a matter of hours by renting cloud computing. Have a look at what happened with the iPhone – the FBI managed to break its security without Apple helping them out. If someone really wants to steal from you or hack you, they will find means to do so. Smart cards are still infinitely safer than mag stripe cards.
