DEFCON 31 Talk Schedule

Hack-A-Sat 4 is quite simply the world's first CTF in space. Now in its 4th year, the Hack-A-Sat competition series aims to enable security researchers of all levels to focus their skills and creativity on solving cyber security challenges on space systems and incentivize innovation in securing these systems. Stop by and witness the 5 finalist teams compete for $100K in prizes, learn more about the history of Hack-A-Sat, and the Moonlighter satellite hosting this year's competition. Competition updates will be presented on the AV stage both Friday and Saturday morning at 11 am PT

Weather balloons’ radiosondes measure and transmit weather data. Besides weather models and forecasts, radiosondes are also important for gathering weather data for satellite launches and human spaceflights. I’ll present a simulation framework for the most popular radiosonde model and present simulations of a jamming attack and a spoofing attack on a receiver. I'll talk about the shortcomings of the military variant of the radiosonde model and suggest a simple way to cope with spoofing attacks.

Will demonstrate how to use SPARTA to develop attack chains against space systems. This presentation will present pre-existing attack chains (e.g., CySat 2023, Hack-a-Sat 3, etc.) that have been performed as well as new attack chains leveraging the SPARTA TTPs. The presentation will include a demonstration of at least one attack chain using a digital twin simulation.

In 2022, aviation tracking privacy (or the lack thereof) has truly entered the global mainstream, with operational security and climate shaming of private jets suddenly discussed all over the world. Following up on previous work presented at the Aerospace Village, we will conduct a deep dive into how we arrived in this position, why nothing has worked so far, and how we need to change our thinking in order to achieve any meaningful privacy in aviation.

Over the past 10 years, armasusisse Science + Technology has been successfully conducting open security research with real avionics hardware, working closely with industry and regulators. The talk will cover our technical results as well as our approach to building trust with regulators and the industry by working as responsibly as possible while still maintaining the openness required to obtain the necessary results and drive change in the wider ecosystem.

The Aeronautics Cyber Range performs penetration testing on DoD aviation weapons systems. Since becoming operational in 2019, the team has accumulated many lessons learned and best practices to support testing of aerospace embedded systems. This talk details how to deal with fundamental challenges of operating this type of facility. Brace yourselves for an incredible journey filled with the obstacles we encountered and the strategies and tactics you can use to avoid our growing pains.

Many US interests heavily depend on space assets. With the rapid development of space technology, security is often overlooked. This talk covers a range of space-based attack scenarios, developed via extensive threat modeling efforts (attack trees, PnGs, etc). The paper being produced from this research effort will be presented to the National Space Council. By addressing these issues, the US can strengthen its resilience in space and ensure the security of critical space-based infrastructures.

In January 2023, Attack Research was invited to perform an on-wing penetration test of a Boeing 737NG that was being decommissioned. Come, listen, and be taken on a journey through this little-explored realm of aviation security. Discover some of our secrets from the decades of combined experience working on in-flight entertainment systems and various aircraft as well as the reasons why airlines and OEMs are urged to open their minds to external expertise and embrace the insights presented.

Join Pete Cooper in a fireside chat with Chris Roberts about his role as the CISO for Boom Supersonic and how he is approaching the challenges of securing a flying platform from the ground up using everything from digital twins to AI. It will also be a chance to discuss what he has learnt across his career and his advice for the next generation coming through.

This is the 5th year of the Aerospace Village and the landscape now is totally different to what it was at the start. This is the story of how a diverse bunch of hackers, engineers, pilots, policy leaders and more from across both the public and private sectors founded and built the Aerospace Village to promote safe, reliable, and trustworthy aviation and space operations.
