So, to emulate a Mifare Ultralight Card with Android Phone. Please note, comments must be approved before they are published. Mifare Classic in general is stated insecure, because its encryption protocol has been cracked. Interested in getting started with these tools? We've made the Pentester Pack that contains all the tools from this tutorial - and some extra Magic Mifare cards.īuying in a pack gives a massive saving of 66 Euros - check out the pack here.

A new generation MIFARE tag that resists classic attacks.

This attack is especially useful when we have: The first of these keys can be sniffed by the Chameleon Mini and easily decoded.Īrmed with this key, we are able to use LibNFC's mfoc tool with the SCL-3711, or the Proxmark 3 RDV2 to perform a nested / hardnested attack to successfully crack all keys and dump the card.

When a reader begins communication with a Mifare Tag, it will send a series of keys to attempt card decryption. Lab401's Chameleon Mini RevE Rebooted is a compact, highly capable tool typically used for 13.56MHz emulation (Mifare, Ultralight, etc). You can also configure reader in the way that it will read Identifier from the specified memory block of MIFARE Classic card that is protected with the same crypto key.LAB401 ACADEMY: Mifare Cracking: Reader Attack with Chameleon Mini RevE Rebooted INTRODUCTION: In order to protect MIFARE Classic 1K (4K) card it is enough to write Identifier (for example, a number that is 3 bytes length and that is send over Wiegand-26) to one of the memory blocks and block access to it by using the crypto key. MIFARE DESDismiss EV1 cards have the highest protection level and flexible file structure of memory. Authentification, exchange of data, work with memory is done by using AES.

This level of MIFARE Plus cards provides 100% compatibility with MIFARE Classic 1K (4K) cards. MIFARE Plus prox cards support 3 levels of security and can be upgraded from one level to another anytime: It uses AES cryptography which is impossible to crack. MIFARE Plus series of cards is designed to provide strong level of security. After that operator can “Flash” readers using the master-card but will not have access to keys and passwords.ĭifferent MIFARE chIP Stile main characteristicsĬryptosecurity that is build in MIFARE Classic chip is considered to be weak nowadays. A master-card is used for readers programming. It is necessary that the owner of the ACS or his representative will come up with passwords and keys and write them to cards and readers. Access cards can be easily copied when a third party has cryptographic keys. Reader will use only open UID of the card that can be easily copied.Ĭustomer / owner of the facility should pay careful attention to cryptoprotection - he must not entrust the processes of card creation, card cryptoprotection write operations to card and readers supplier, ACS mounter or anybody alse. MIFARE cards are brought from manufacturer without any protection.

MIFARE Ultralight cards (except MIFARE Ultralight C) don’t have copy protection and can be compared to traditional Proximity-cards. The following MIFARE cards can provide this : Classic, Plus, DESDismiss. It is necessary to use cards with copy protection function in order to arrange the access control system and be sure in its safety.
