Capture the Signal takes part at Hardwear.io Virtual Con!
Hardwear.io Virtual Con!
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.
GNURadio natively supports the tunneling of signals via ZeroMQ, so that the players can focus on the real challenge: reverse engineer the protocols without bothering the distribution of the signals. For the same reason, we provide ready-to-use scripts to remotely access the radio streams, as setting up the GNURadio toolchain is time consuming and is not relevant to the core of the challenge.
We also provide a VM image with all needed software to reverse engineer the signals. Of course, participants are welcome in using their own setup.
