MFOC is an open source implementation of “offline nested” attack by Nethemba. It allows to recover authentication keys from MIFARE Classic card.

In conclusion, we’ve identified how to use a few basic NFC and MIFARE commands to read and detect a tag. With the few more MFOC commands we were able to crack a generic NFC key. Eventually, we dump the content of the tag’s memory if it was using default keys. This makes up more than 75% of the tags I have tried so far. May 11, 2019 It turned out they were using a Mifare Classic card. This type of card can easily be hacked as the encryption keys protecting the data are vulnerable to several exploits. Since then, a lot of public exploits to crack MIFARE Classic tags have been developed. We are going to use one of them for this project. Cracking the card To perform this attack, you will need a computer running Kali Linux, a PN532 NFC/RFID controller breakout board and a USB to TTL Serial Cable. You can use any other Linux distribution than.

Mifare Crack

1. Connect PN532 to Linux, macOS, Windows or Android Devices.

2. Open a terminal and read the card type with the cmd nfc-list.

3. Start to crack keys with the command mfoc -O card.mfd.

4. Then we get the mifare classic dump file – card.mfd.

5. Open dump file vim card.mfd and read as HEX type:%!xxd

Tips

1. MFOC is useful if it exist known key of one sector.
2. MFOC is only for recover keys for Mifare Classic type card.
3. The speed of cracking is depending on the sectors that encrypted.
4. The mfd file can be used to clone to another card.
