RF Hackers CTF

Do you have what it takes to hack WiFi, Bluetooth, and Software Defined Radio (SDR)?

RF Hackers Sanctuary (the group formerly known as Wireless Village) is once again holding the Radio Frequency Capture the Flag (RFCTF) at Circle City Con 2022.  RFHS runs this game to teach security concepts and to give people a safe and legal way to practice attacks against new and old wireless technologies. 

RF Hackers Sanctuary Logo

We cater to both those who are new to radio communications as well as to those who have been playing for a long time. We are looking for inexperienced players on up to the SIGINT secret squirrels to play our games. The RFCTF can be played with a little knowledge, a pen tester’s determination, and $0 to $$$$$ worth of special equipment.  Our new virtual RFCTF can be played completely remotely without needing any specialized equipment at all, just using your web browser!  The key is to read the clues, determine the goal of each challenge, and have fun learning.


There will be clues everywhere, and we will provide periodic updates via discord and twitter. Make sure you pay attention to what’s happening at the RFCTF desk, #rfctf on our discord, on Twitter @rf_ctf, @rfhackers, and the interwebz, etc. If you have a question – ASK! We may or may not answer, at our discretion.



Our virtual RFCTF environment is played remotely over ssh or through a web browser.  It may help to have additional tools installed on your local machine, but it isn’t required.

To score you will need to submit flags which will range from decoding transmissions in the spectrum, passphrases used to gain access to wireless access points, or even files located on servers. Once you capture the flag, submit it to the scoreboard right away, if you are confident it is worth *positive* points.  Some flags will be worth more points the earlier they are submitted, and others will be negative. Offense and defense are fully in play by the participants, the RFCTF organizers, and the Conference itself. Play nice, and we might also play nice.
