The belated July 2025 recipient for the Great Scott Gadgets Free Stuff Program is Murat Sever, a professor from Turkey who teaches at TOBB ETU University and recently ran a workshop titled “Simple Replay Attack Demo with GNU Radio.” In this workshop, Murat utilized several open-source software and hardware tools to demonstrate how to receive and transmit RF signals. Workshop participants then used SDR and GNU Radio to perform replay attacks with the captured radio signals. We sent a handful of HackRF Ones to Murat for participants to learn and experiment with in this workshop. He has also informed us that the HackRF Ones will be put to use in the course he is teaching this fall on SDR applications! We are glad that we could continue to support Murat’s efforts to educate others about the capabilities of software defined radio and wish him and his students best of luck with their fall term!
