Signal Hunter

Fox Hunt Challenge

The electromagnetic spectrum is a battlefield, and most people don't even know the war is happening. At the Ham Radio Fox Hunt, you'll step into the role of a signal hunter, using radio frequency triangulation to track down hidden transmitters buried somewhere in the grid. It's raw, hands-on, and completely analog in the most cyberpunk way possible. No GUIs. No dashboards. Just you, an antenna, and rogue signals that don't want to be found.

This isn't just a game. It's a crash course in the same principles that drive real-world cybersecurity. Unauthorized transmitters, rogue access points, and covert RF beacons are live threats in today's connected world. Learning to hunt a signal teaches you how adversaries hide, how to think spatially about detection, and how physical-layer attacks operate beneath the software stack. Whether you're a seasoned InfoSec pro or just breaking into the field, this experience will sharpen instincts that no CTF challenge can replicate.

Find the fox. Own the frequency. Every beacon you track is a lesson in how signals hide, and how defenders find them. The same instincts that win a fox hunt are the ones that catch a rogue device on a corporate network.

Grab your antenna. Hit the streets. The fox is running. The net waits for no one. 🦊📡
