Capture the Signal takes part at Hardwear.io USA Conference 2021!

Capture the Signal (CTS) is a new challenge-based CTF that focuses exclusively on the reverse engineering of radio signals. This activity is also known as "blind signal analysis" as the signals' specification are unknown to the attacker. This contest is organized by renowned community radio-hackers for researchers, hackers, and practitioners in the field!

Contestants should use their RF-hacking kung-fu and tools like GNURadio, GQRX, URH, Python, C, anything, to examine a series of increasingly complex radio signals to extract key information leading them to the final, exit signal.The game runs virtually, over Internet. The radio signals will be distributed "over IP". The use of IP eliminates the complexity of deploying actual radios and transmitting RF over the air. We use GNURadio for that.
