This poster serves as a supplement to the Operational Evaluation Division (OED) Cyber Lab breakout session “Adversaries and Airwaves: An Introduction to Wifi / Radio Frequency Hacking.” This poster presentation was prepared for the DATAWorks 2022 Conference held April 26-28. A software defined radio (SDR) is a radio system where components traditionally implemented with dedicated or analog hardware instead are implemented in software. This allows these devices to have incredible flexibility in the types of signals, protocols and applications a single piece of hardware can support. This poster presents several hands-on demonstrations using SDRs that DATAWorks attendees can experiment with as they chat with members of the OED Cyber Lab. The goal is to provide attendees the opportunity to experiment with hardware and software they may not be familiar with and to demonstrate the wide breadth of applications these ubiquitous, affordable devices can support.
