Talk: Introduction to Flipper Zero app development with @MrDerekJamison (YouTube) jamisonderek (Github) !!

Flipper Zero is a pocket-sized multi-tool for hacking digital systems. It originally gained traction on Kickstarter in 2020, and now it’s available from several vendors, including the Hacker Warehouse booth at DEF CON. As a fully open-source platform, Flipper Zero gives you the freedom to create your own apps or modify its firmware to suit your needs.

In today’s talk, we’ll dive into setting up a development environment for Flipper Zero applications, which is applicable to Windows, Linux, and macOS. We’ll walk through the code of a simple, single-screen app written in C, and then show you how to modify it to create your own custom application.

By writing your own apps, you’ll unlock a whole new world of possibilities with Flipper Zero—whether it’s interacting with hardware (UART, I2C, SPI, 1-Wire, bit-banging, etc.) or sending and receiving infrared and sub-GHz signals.

Talk: What I Learned From Building A Tabletop Security Exercise! with Dwayne McDaniel

Bio: Dwayne has been working as a Developer Advocate since 2014 and has been involved in tech communities since 2005. His entire mission is to “help people figure stuff out.” He loves sharing his knowledge, and he has done so by giving talks at hundreds of events worldwide. He has been fortunate enough to speak at institutions like MIT and Stanford and internationally in Paris and Iceland. Dwayne currently lives in Chicago. Outside of tech, he loves karaoke, live music, and crochet. On LinkedIn at https://www.linkedin.com/in/dwaynemcdaniel/

Abstract: At DEFCON 32, my team taught over 160 people the limitations of manual code review to solve secrets sprawl. We did not use new tech. We did not use computers or anything that needed electricity. We used paper cards. What we learned along the way was eye-opening and changed the way I think about security.

This talk is a quick recap of the surprising findings we unexpectedly gathered and the power of getting away from the keyboard. I will reveal my new theory on driving better conversations across teams and roles to actually try and improve security, and not just show how clever we are.

Talk: From Noise to Knowledge: Demystifying RF Signals with Ty Purcell !!!

Abstract: The expansion of wireless technologies has introduced a diverse range of hardware, protocols, and radio frequencies. When a large mix of acronyms and names like LoRa, BTLE, ZigBee, RFID and Wi-Fi are thrown-in, one can easily get confused and overwhelmed.

This presentation offers a comprehensive introduction to the RF spectrum for those new to wireless security that will also provide value for experienced practitioners. By taking a broad, big-picture approach, we’ll begin by exploring the electromagnetic spectrum, covering familiar technologies and concepts like infrared, visible light, and x-rays, before narrowing our focus to the portion dedicated to radio frequencies. Key concepts such as wavelength, frequency, and modulation will be explained along the way.

We’ll then delve into the specific wireless frequencies and protocols security professionals are likely to encounter, providing practical examples and tools for detecting, analyzing, and testing these devices and signals.
