1 x PN532 NFC/RFID controller breakout board = 39.95 USD.

1 x FTDI Serial TTL-232 USB Cable = 17.95 USD.

Then you will be less frustrated if you've made the "wrong choice".

I'd recommend trying to build the software before committing to a hardware purchase. I've personally bought all three of these devices, and after buying the Proxmark3 I don't use my PN532 kits much anymore. If you're interested in more experimentation with RFID technology, buy this device. It's easy to get the software built, but it's a significant investment to buy the hardware. Proxmark3 is the "expensive, powerful and quick" option.

If your time isn't valuable to you, and you're comfortable patching specific git versions of software, go this way. It's a pain to get the code required built, and it only works on Linux. PN532 is the "cheap, basic and slow" option, which uses the software packages described below.

However, you can always still sideload card dumps onto your phone or the emulator to read them.

If your phone doesn't support MIFARE Classic, or you don't have an Android device, this exercise is pretty much pointless. You can verify MIFARE Classic support in Metrodroid's about screen. In order to read MIFARE Classic cards with your phone, you'll also need an Android phone with an NXP NFC chipset. However, if you're using the proxmark3 you can also run on non-Linux systems. You'll also need to be familiar with compiling software on Linux, and fetching specific git versions of things. In order to continue, you'll need a Linux computer with a libnfc-compatible NFC device. On some of the transit card pages, there may be a way to check based on the appearance of the card - but these are specific to each agency. Unfortunately, there's not always an easy way to tell what card you have, so at worst you may be out some money if you buy the wrong hardware. Most of them don't implement countermeasures against cracking, some of them implement Crypto-1 poorly (eg: weak RNG), or have backdoors.

It has less security flaws (in MFC mode), but can still be cracked if you know at least 1 key (eg: sniffed from a reader).Ĭlone cards: there are many manufacturers of "clone" cards, most of them are not licensed by the manufacturer. MIFARE Classic EV1 / MIFARE Plus: newer revisions, which can emulate a MIFARE Classic card.

MIFARE Classic: the original card, which can be cracked even if you don't know any keys.

Touch_n_Go (key diversification algorithm is known, see tng2json.py).

Cubic Nextfare MFC including Go (SEQ), Transit Access Card and MspGoto.

No two cards of the same type have any of the same keys, so you'll need to extract it from a reader.

Umarsh cards (but static keys are different per deployment)Įvery card only uses keys that are unique to that card.

ERG MFC, including Manly Fast Ferry and Metrocard (Christchurch).

Some keys are unique per-card (and you need to crack them), but at least 1 is common to every card, and therefore can be cracked offline.

RKF (but exact keys differ per deployment)Ĭards that use partially-diversified keys.

Zolotaya Korona (but exact keys differ per deployment).

These cards use the same key on every card in that network (ie: every CharlieCard has the same keys). These cards use a "default" key, eg: all- FF, all- 00, the MIFARE Application Directory (MAD) or NDEF keys.Ĭards that have the same keys on every card Key usage by transit card Cards that use "default" keys

Mifare cracking install#

You need to install keys for your card, which you get by cracking it. Even when "supported", this will always come up as a "fully locked card". Metrodroid does not include any agency-specific keys, even static ones. Practical attacks against Crypto-1 (the encryption and authentication algorithm used by MIFARE Classic) have been publicly known since at least 2008, and the manufacturer no longer recommends using these cards in "any security relevant application" since 2015. MIFARE Classic (MFC) is used by many older public transit smartcard systems. It is not possible to crack a card with just your Android phone, as it does not permit low level access to the NFC hardware.

I can't give email support about this process either, or do a crack-by-mail service. Please don't file GitHub issues about this. This information is intended to help give some pointers about the actual cracking process of cards, so you can load keys to use with Metrodroid.
