RFID Event:
Chaos Communication Congress 27th (27C3) 2010 Abstract: Popular contactless systems for physical access control still rely on obscurity. As we have shown, time and time again, proprietary encryption systems are weak and easy to break. In a follow-up to last year's presentation we will now demonstrate attacks on systems with 'proper' cryptographic algorithms. Since we broke the last of the big players on the market at 26C3, most vendors are now migrating to new systems which rectify our main point of concern: proprietary algorithms. All new technologies use AES or 3DES for encryption and/or authentication and vendors tirelessly tout the security of their systems and the use of these algorithms between card, reader and host. We will discuss the design of the successor to a system we attacked last year, and demonstrate how a system can be insecure despite the use of secure cryptoprimitives.

Chaos Communication Congress 27th (27C3) 2010 Abstract: Lightning talk on biohacking, complete with cyborg speaker, implant demonstrations, and knowledge of how to hack your own perception of electromagnetic radiation for approximately thirty Euros. A talk on what's become my specialty - biohacking, or meathacking, whatever you wanna call it. I've got a full set of home-brewed implants, a subdermal RFID, a sort of cult on the Internet plus things like proven designs for cheap EM sensory nodes, experimental verification of that shit I'm claiming, etc. I have videos of procedures, photos of what I've been doing and the like, and will happily make gory slides for all to see. Can do demos of the EM nodes and RFID chip as well. I want to talk about the grinder movement - underground biohacking - it's my life. Thus, my article in H+ Magazine: "A call to arms for biohackers".

Chaos Communication Congress 27th (27C3) 2010 Abstract: How to reverse engineer the data format of a real-world RFID based debit card system. One of Asia’s most popular electronic payment systems uses insecure technology. The EasyCard system, established in 2001, is the most popular stored-valued card in Taiwan. With more than 18 million issued cards, it is the predominant means of paying for public transportation services in the capital Taipei. In 2010, use of the EasyCard was extended beyond transportation. Card holders can now pay in all major convenience stores like 7eleven, coffe shops like Starbucks and and major retail companies like SOGO. Despite the large fraud potential, the EasyCard system uses the MIFARE Classic RFID technology, whose proprietary encryption cipher CRYPTO1 relied on obscurity and was first publicly broken several years ago at 24C3 This presentation analyzes the results of combining the practical attacks on the MIFARE Classic CRYPTO1 system in the context of the EasyCard payment system. It describes the process of reverse- engineering the actual content of the card to discover the public transportation transaction log, the account balance and how the daily spending limit work. Furthermore, the talk will present how fundamentally flawed the system is, and how easy it is to add or subtract monetary value to/from the card. Cards manipulated as described in the talk have been accepted by the payment system.

While young children have the tiny hands and fingers that most hackers/tinkerers wish they possessed from time to time, their fine motor skills aren’t always up to par when it comes to operating complicated electronics. People are always looking for ways to make their home entertainment systems accessible to their kids, and [Humpadilly] is no [...]

Here’s another audio playback hack that uses physical tokens to choose what you’re listening to. It uses Touchatag RFID hardware to control iTunes. The concept is very similar to the standalone Arduino jukebox we saw on Wednesday except this one interfaces with your computer and the tags select entire albums instead of just one song. [...]

[Dominik] built a fun musical toy for his daughter [Anna]. It’s a jukebox that lets her play her favorite tunes using RFID tags to select between them. The project is simple, yet robust. The enclosure is a wooden craft box that you can pick up for a couple of bucks. Inside there’s an Arduino with [...]

[Aaron] was looking for a cheap RFID reader that had some easy to follow documentation and a standardized interface.

RFID Event:
Ruxcon 2010 Abstract: RFID technology is the new cool. It’s the access pass around our neck, the overpriced contactless train ticket that goes “ping” and the payment card that doesn’t bother with two factor authentication. Even with issues with the underlying architecture, the majority of implementations out there haven’t quite thought things through (like getting rid of manufacturers keys and locking down the read/write access). We’re going to melt back the noooiiiice looking plastic on RFIDs and see what’s inside before the government starts using them as mind control devices.

PhreakNIC 11 Abstract: Last year's presentation was high level functionality and basic knowledge of what RFID is. The year they will present the low level technical specs on different communication types, the physics behind RFID reading and transmitting, and the actual circuitry of an RFID tag and what it takes to make them operate more consistently. The presentation will also cover actual tag data and coding schemes with standardization including EPC Gen 2 and other ISO standards such as PayPass RFID enabled credit cards. There will be reader/writer demonstrations as well as other proof of concept demonstrations.

Black Hat EU 2010 Abstract: With the transition to RFID enabled travel documents (including the ePassport and the eID) in Europe, a correct implementation of the authentication and verification of passport technologies is necessary. The complexity if the technology can cause a myriad of security issues in the identification. Our presentation examines the eMRTD security controls and suggests correct implementations to enable identification as a mechanism. We also examine the dangers of incorrect implementations and the resulting consequences.
