Capture the Signal is a challenge-based CTF that focuses exclusively on the reverse engineering of radio signals.
This activity is also known as “blind signal analysis” as the specifications of the signal are not known to the attacker.
This contest is organized by Trend Micro’s researchers 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 next signal.
The game is hosted on site. The radio signals will be distributed via RF, and
“over IP” as an alternative. The use of IP eliminates the complexity of
deploying actual radios and transmitting RF over the air.
