Running a Software Defined Radio CTF using challengectl
Explains how the RF Village Capture the Flag team designs wireless challenges and automates over-the-air signal transmission using challengectl.
Summary
The Evolution of RF Capture the Flag Competitions
Software-Defined Radio (SDR) has become a central discipline in cybersecurity competitions, challenging participants to capture, demodulate, and reverse-engineer novel RF signals in real time.
Designing Engaging and Educational RF Challenges
Dan Perret outlines the design philosophy behind RF Village CTF challenges, spanning basic analog modulation, digital telemetry decoding, satellite downlink decoding, and hidden signal steganography.
Automated Signal Transmission with challengectl
RF Hackers Sanctuary engineers developed challengectl, an open-source orchestration tool that schedules, modulates, and transmits multiple concurrent challenge signals across SDR transmitters.
Empowering Communities to Host Wireless Competitions
Releasing open-source CTF transmission software enables schools, hacker conferences, and radio clubs to easily organize their own hands-on wireless security competitions.
