SDR Videos from DEFCON 29

Recently some videos from this years (mostly virtual) DEFCON 29 conference have been uploaded to YouTube. Defcon is a major yearly conference all about information security, and some of the talks deal with wireless and SDR topics. Some interesting talks that we've found from the main Defcon and Villages are posted below.

You can view all the talks directly as well as the many others via the main stage DEFCON YouTube channel, the ICS Village Channel, RF Village Channel and the Aerospace Village. There are also several talks from the Ham Radio Village recorded on Twitch. Did we miss any interesting talks? Please let us know in the comments.

Smart Meters: I'm Hacking Infrastructure and So Should You (Hash Salehi)

Why Smart Meters? This is a question Hash is often asked. There's no bitcoin or credit card numbers hiding inside, so he must want to steal power, right? Openly analyzing the technology running our critical infrastructure and publishing the findings is something Hash is passionate about. In the wake of the great Texas freeze of 2021, we can no longer "hope" those in power will make decisions that are in the people's best interest. This talk will present research on the Landis+Gyr GridStream series of smart meters used by Oncor, the largest energy provider in Texas.

Cyber attacks on Industrial Control Systems (ICS) differ in scope and impact based on a number of factors, including the adversary's intent, sophistication and capabilities, and familiarity with ICS and automated indutrial processes. In order to understand, identify and address the specific points that can prevent or stop an attack, a systematic model known as "Cyber Kill Chain" is detailed, a term that comes from the military environment and registered by the Lockheed Martin company. While most are familiar with terms and theoretical diagrams of how security should be implemented, in this talk we want to present live how an attack chain occurs from scratch to compromise industrial devices, the full kill chain, based in our experiences. The goal is to land these threats into the real world without the need to carry out these attacks with a nation-state budget.

DEF CON 29 - Paz Hameiri - TEMPEST Radio Station

TEMPEST is a cyber security term that refers to the use of electromagnetic energy emissions generated by electronic devices to leak data out of a target device. The attacks may be passive (where the attacker receives the emissions and recovers the data) or active (where the attacker uses dedicated malware to target and emit specific data).

In this talk I present a new side channel attack that uses GPU memory transfers to emit electromagnetic waves which are then received and processed by the attacker. Software developed for this work encodes audio on one computer and transmits it to the reception equipment positioned fifty feet away. The signals are received and processed and the audio is decoded and played. The maximum bit rate achieved was 33kbit/s and more than 99% of the packets were received.

Frequency selection not only enables maximization of signal quality over distance, but also enables the attacker to receive signals from a specific computer when several computers in the area are active. The software developed demonstrates audio packets transfers, but other types of digital data may be transmitted using the same technique.

DEF CON 29 RF Village - cemaxecuter - RF Propagation and Visualization with DragonOS

"Today's presentation will start with a brief history of DragonOS, where it started and where it's at today. After a short introduction, I'll dive into the subject of visualizing RF propagation with DragonOS. I'll be showing a fresh OS install and the necessary steps to generate a rough estimate of a transmitter based on SRTM-3 elevation data, as well as a new feature enabling visualization/calculations of the path between transmitter and receiver .

Topics and hands on (pre-recorded) demonstrations will include the following,

  • SPLAT! is an RF Signal Propagation, Loss, And Terrain analysis tool for the electromagnetic spectrum between 20 MHz and 20 GHz.
  • Signal Server Multi-threaded RF coverage calculator
  • Dr. Bill Walker's role
  • Signal Server and DragonOS integration
  • DF-Aggregator Developer / Modifications for visualization

I’ll conclude talking about future improvements to RF propagation and visualization tools."

SDRA2020 Online Conference Videos

The Software Defined Radio Academy is an organization that holds a conference within the yearly HAMRADIO fair in Friedrichshafen, Germany. This year due to the pandemic the conference was held online, and recently videos from the various talks have begun to slowly get uploaded to their YouTube channel.

The talks are typically very technical in nature, but if you're interested in cutting edge SDR research and applications then these are good talks to get caught up on. Currently there are seven videos that have been uploaded, but we are expecting that there are more to come since there are more talks listed in their programme. They appear to be uploading one video per day at the moment so get subscribed to their YouTube channel for the upcoming videos.

The currently uploaded talks include:

  • A Keynote interview with N1UL Dr. Ulrich Rohde
  • Laurence Barker G8NJJ: Using Xilinx Vivado for SDR Development
  • Edwin Richter DC9OE, Crt Valentincic S56GYK: Usage of higher order Nyquist Zones with Direct Sampling Devices
  • Prof. Dr. Michael Hartje DK5HH: Signalprocessing in the man made noise measurement system ENAMS
  • Bart Somers PE1RIK: Long term spectrum monitoring using GNUradio and Python

We are looking forward to the upcoming talks like the one by Dr. Bastian Bloessl DF1BBL that discusses the GNU Radio on Android implementation.

DEF CON 27 SDR Talks: Antennas for Surveillance, Ford Keyfob Hack, Smart TV Wireless Side Channel Attack

Talks from this years DEF CON 27 conference which was held back in August are now available on YouTube. DEFCON is a yearly conference that a focuses on information security topics and often includes talks about SDRs and other wireless radio topics too. In particular we wanted to highlight the the DEF CON 27 Wireless Village playlist which contains numerous talks related to wireless, radio and SDRs.

Most talks from the wireless village relate to WiFi, but one talk with some very useful information that we really enjoyed was "Antennas for Surveillance" by Alex Zakhorov. 

We will cover the various kinds of antennas available to optimized your SDR radio for different types of spectrum monitoring. We will also explain why RF filters are necessary on most SDR's and when Low Noise Amplifiers help, and when Low Noise Amplifiers hurt reception.

Another interest talk was called "The Ford Hack Raptor Captor video" by Dale Wooden (Woody) where he shows how he used an RTL-SDR and HackRF to hack a Ford car key fob. If you're interested we wrote about the Hak5 videos on this hack in a previous post.

This talk will show flaws with development of security protocols in New Ford key fobs. This will exploit several areas. The ability for a denial of service to the keyfob WITHOUT jamming. How to trick the vehicle into resetting its rolling code count. How to lock, unlock, start, stop, and open the trunk of ford vehicles using a replay attacked after resetting rolling code count. How to find the master access code for Fords keypad to bypass security. This talk will also demonstrate how to reset your key fobs if they are attacked by a deauth attack. We will also demonstrate gnu-radio script to automate RF collection of Ford key fobs. As seen on HAK5 episodes 2523-2525

Outside of the Wireless village there were also some interesting SDR topics including this talk titled "SDR Against Smart TVs URL Channel Injection Attacks" by Pedro Cabrera Camara. If you're interested we also wrote about Pedro's work in a previous post.

Software-defined-radio has revolutionized the state of the art in IoT security and especially one of the most widespread devices: Smart TV. This presentation will show in detail the HbbTV platform of Smart TV, to understand and demonstrate two attacks on these televisions using low cost SDR devices: TV channel and HbbTV server impersonation (channel and URL injection). This last attack will allow more sophisticated remote attacks: social engineering, keylogging, crypto-mining, and browser vulnerability assessment.

Talks from GNU Radio Days 2019

GNU Radio Days 2019 was a workshop held back in June. Within the last week recordings of the talks have been uploaded to YouTube by the Software Defined Radio Academy channel. The talks cover a wide range of cutting edge SDR research topics and projects. Many of the presenters have also made use of RTL-SDR dongles, as well as other higher end SDRs in their research.

All the talks are combined into two 3 hour long videos from the morning and day sessions from day one. Day two also has two videos that consist of recordings from the tutorial sessions which make use of the PlutoSDR. Finally there is also the keynote speech from Marcus Müller where he dives into the internal workings of GNU Radio.

Below we list the talks with timestamps for the YouTube video. Short text abstracts for each of the talks can also be found in the conference book. We note that not all the abstracts appear to have been presented in the videos, so it may be worth checking out the book for missed talks about passive radar, a 60 GHz link, embedded GNU Radio on a PlutoSDR, an SDR 802.11 infrared transmission system, PHY-MAC layer prototyping in dense IoT networks and hacking the DSMx Drone RC protocol.
