MIFARE Classic

Here are the steps to follow in order to read your cards. Your goal is to find as many keys as possible. The keys unlock sections of your card for the Flipper to read them - you must have a card. Once you read enough sections, you can use an emulated or cloned card at the original card reader to unlock it (sometimes even without finding all of the keys!).

Reading the card

Steps:

1. Dictionary attack: Try to scan your MIFARE Classic card with NFC -> Read. It will try a dictionary attack of default keys to unlock your card, as well as any keys you may have found through other methods. Do not interrupt the dictionary attack, it may take a while! If it finds 32/32 keys (or 80/80) with 16/16 sectors (or 40/40), congratulations and proceed to "Emulation". If not, continue to step 2.
2. Mfkey32 attack (): If you have only a few keys found or no keys found, you can get mor

libnfc supports UUID writable cards and even has some dedicated tools for them.

However it doesn't work with some of the cards found on eBay that are even simpler to use. Sector 0 is unlocked and can be written without any additional commands. libnfc requires a small patch to get it working.

Following has been tested under ArchLinux with modified libnfc 1.5.1, mfoc 0.10.2 and a SCL3711 dongle.

Patch & recompile libnfc

The patch is fairly simple, open libnfc-1.5.1/utils/nfc-mfclassic.c and comment 2 lines (it was lines 384 and 385 for me):
