At the OHM2013 conference held last summer outside Amsterdam, J. M. Friedt discussed his use of GNURadio as a signal processing prototyping tool. He writes, “We demonstrate the use of this software environment for implementing new digial communication mode decoding algorithms, qualifying low frequency circuits by using the audio card as a network analyzer, all […]
In this presentation from DEFCON 21, Adam “Major Malfunction” Laurie and Zac Franken of Aperture Labs go hardcore with chip analysis. For some time it has been possible to discover the inner workings of microprocessors with the help of a microscope and some nasty chemicals such as fuming nitric acid. However, unless you have access […]
PHd student Karl Koscher and software engineer Eric Butler have teamed up to research phone SIM cards and how they are used to run small apps. At the DEFCON 21 conference they presented their methodology and results. “This talk, based on our experience building SIM apps for the Toorcamp GSM network, explains what (U)SIM Toolkit […]
Courtney Lancaster gave this talk at Shmoocon 2014 outlining the types of information available from vehicle infotainment systems “This talk will take an in-depth look at infotainment technologies and how to forensically acquire the data associated with the functionalities that exist across various manufacturers. Furthermore, we will cover the challenges of conducting digital forensics on […]
In this video from the 30th Chaos Communications Congress, Adrian Dabrowski lectured on RFID based access control systems which are becoming common in Europe. These systems debuted in 2006 and use RFID cards as a substitute for a previous mechanical key system to allow emergency service, delivery and other personnel unassisted access to the common […]
The NRF24L01+ is a popular wireless communications module from Nordic that interfaces well with MCU applications. In this detailed video tutorial, Kevin Darrah outlines how to use it with the Arduino. Source code is available from Kevin Darrah’s website.
Orthogonal frequency-division multiplexing or OFDM is a method of encoding digital data on multiple carrier frequencies. At this presentation from them recent FOSDEM 2014 conference in Brussels, Martin Braun explained the use of GNU Radio software and an SDR transceiver to explore OFDM block basics, how to set up links between nodes and how to […]
In this presentation from DEFCON21, Albert Garcia Illera and Javier Vazquez Vidal discuss the development and operation of an Arduino based device for controlling automotive functions in 2010 and newer model vehicles that use the K-Line protocol (although we’re told it could easily be modified with newer protocols.) Additionally they also cover basic forensic analysis […]
In this presentation from the 2013 Digital Communications Conference, Bruce Perens K6BP discusses FreeDV, CODEC2 and “The HT of the Future”. Bruce is active in advancing interest in open-source digital voice to Amateur Radio on both HF and VHF/UHF. Here he also discusses D-STAR and Yaesu’s controversial new proprietary VHF/UHF digital amateur radio communications protocol.
At the recent 30C3 conference in Hamburg, Germany, Andrew Reiter outlined his efforts in using inexpensive RTL-SDR dongles to build a distributed RF scanner array for monitoring and spectrum mapping. Software-Defined Radio (SDR) has increased in popularity in recent years due to the decrease in hardware costs and increase in processing power. One example of […]
In this presentation from the recent Chaos Communications Congress conference in Hamburg, Germany, Karsten Becker highlighted the Plain Simple Hardware Description Language (PSHDL) programming language for FPGAs. PSHDL is a new language that purports to have a much better syntax similar to C, making it easier for developers to learn. If you’ve tried to learn […]
In this talk from the 2013 Digital Communications Conference (DCC) co-sponsored by the ARRL and TAPR, developer Michael Ossmann discussed the origins and development of the HackRF Jawbreaker SDR transceiver. This is Michael’s first talk at an amateur radio oriented conference.
At the GrrCON 2013 conference last Fall, Philip Polstra presented on the use of the AirDeck Linux based aero mobile pen testing device. This presentation will introduce the AirDeck which is the latest extension to The Deck penetration testing and forensics program. The Deck made its US debut at GrrCON 2012. The Deck is a […]
Fabrice Muller writes informing of this recent efforts using the STM32F429 Discovery Board to run a Sega emulator: Yesterday I made this adaptation from the Alessandro Rocchegiani sega master system emulator. You can seen the original work here. After trying to adapt this emulator to my smt32 VGA output board I faced some problems with […]
Stephen A. Ridley gave this presentation at the recently concluded Chaos Communications Conference (30C3) in Hamburg, Germany. He outlines his recent research into practical ARM exploitation on Linux and Android (for embedded applications and mobile devices). He demonstrates these techniques and discusses how they were discovered using several custom built ARM hardware development platforms. He […]
This presentation on extracting keys from FPGAs, OTP Tokens and door locks is from the recent Chaos Communications Conference (CCC) in Hamburg, Germany. In it David briefly introduces implementation attacks and side-channel analysis (SCA) in particular, along with related methods to bypass security mechanisms and extract secret keys. “The main focus is on three case […]
In this video from the 2013 Maker Faire New York, Don Coleman takes the stage in New York to discuss Near Field Communication (NFC) using the Adafruit and Seeed Studio NFC shields on an Arduino. Coleman is a software developer and is co-authoring a book on NFC, PhoneGap and Arduino for O’Reilly. Via Make.
This presentation by Karsten Becker was given at this week’s 30C3 Chaos Communications Congress (CCC) conference in Hamburg, Germany. In this talk I want to show you around in the mysterious world of Field Programmable Gate Arrays, or short FPGAs. The aim is to enable you to get a rough understanding on what FPGAs are […]
Karsten Nohl gave this presentation at the 2013 BlackHat conference in Las Vegas. “The protection pretense of SIM cards is based on the understanding that they have never been exploited. This talk ends this myth of unbreakable SIM cards and illustrates that the cards — like any other computing system — are plagued by implementation […]
At the recent GRCon2013, SDR guru Balint Seeber delivered this presentation on using GNU Radio to create new blocks and prototype flowgraphs relating to FasTrak RFID (used in traffic toll collection system), MUltiple SIgnal Classification (MUSIC) Direction Finding, RADAR Detection and Multi-channel Decodings.
