They are all using a PN532 NFC Controller chip and a ST7 microcontroler unit. This product is made by Advanced Card Systems Limited and seems to be available in different layouts but hardware doesn't differ so much. The USB reader works at 13.56MHz (High Frequency RFID) and has a readout distance of about 4 cm (1 inch) when used with the Touchatag RFID tags. Touchatag is ACS ACR122(U) NFC Reader USB RFID reader.

Chosen ingredients: Backtrack | Touchatag starter package Tested on: BackTrack 4 R2, BackTrack 5 Final, (32bit) Dependencies apt-get install flex libpcsclite-dev libusb-dev checkinstall 0x01 - Hardware Touchatag - ACR122U This cookbook is proof of concept how easy that can be done. After cracking all keys, hackers are able to change name, students university number, expiration date. At least one sector is always encrypted with default key. Anyone with 50 € reader can use this weakness against your infrastructure. There is no protection against cloning or modifications.

Uses 13.56 Mhz contactless smartcard standard, proprietary CRYPTO1 with 48 bits keys. Mifare Classic is a inexpensive, entry-level chip, based on ISO/IEC 14443 Type A, 1kB or 4kB. By some estimates, there are 500 million MIFARE cards deployed worldwide, and the majority of them are MIFARE Classic cards. The MIFARE Classic card is used in physical access control systems (PACS) and contact less payment systems (including tollway and public transportation systems). Some of you may have read that the proprietary symmetric key cryptographic algorithm of the MIFARE Classic card has been broken. We made this two cents just for fun and because we love BackTrack. All the research and implementation was made by other people and communities and is publicly available.

NOT to be used in illegal circumstances (for example to abuse, hack or trick a system which the reader does not have specific authorizations to such as ticketing systems, public transport, University/ISIC cards, building access systems or whatsoever systems using Mifare Classic as core technology).As-is without any warranty, support or liability - any damages or consequences obtained as a result of consulting this information if purely on the side of the reader.For informational use only as part of academic or research study, especially in the field of informational security, cryptography and secure systems.But looks like some organizations have preferred using the older cards thus putting their customers at risk.DISCLAIMER: The information and reference implementation is provided: These cards have been discontinued a long time ago, because of the risks mentioned. Once the keys have been leaked the card can be manipulated to any extent according to the attackers wishes.

The cryptosystems in these cards can leak information, leading to the full keys leaking out in around 7 hours. The other two use MIFARE DESFire, which in turn are vulnerable to side-channel attacks. The card in question in the dining card uses MIFARE Classic card, which is known to be easy to manipulate. The social security card has approximately seven million users. The researchers stated that there were at least three vulnerable cards, a social security card with banking service, a payment card for transportation and shopping, and a dining card.

Once that was done, the card was cloned and the data on it rewritten through the android app.Īttacks on other kinds of MIFARE cards (specifically, MIFARE DESFire and MIFARE Ultralight) are known to exist.

Using tools available in abundance, the attacker managed to crack theauthentication of the cards. This is however restricted to only these specific cards because of the format restrictions. This particular app can rewrite data on the card for example, increasing the balance left on it to 10,000 Chilean pesos (approximately 15 US dollars). Trend researchers, after inspecting the app have found that the app could read and write onto the smart cards through any phone equipped with NFC.

Manufacturer and memory content of a MIFARE Classic card Working Trend Micro researchers have given the instance of recent hacking of BIP. An attacker is able to clone or modify a MIFARE Classic card in under 10 seconds, and the equipment (such as the Proxmark3), together with any needed support, is sold online.

MIFARE refers to a family of chips widely used in contactless smart cards and proximity cards.) series of cards (MIFARE Classic), which is known to have multiple security problems.
