Welcome to the Geocaching Capture The Flag (CTF) Challenge Page!

This series of caches is designed to educate geocachers in computer security basics, basic cryptography, malware recognition, and more to come. To complete a cache, you must complete the online exercises on this site. There is a resource page with information to help you. The challenges will be beginner level, but it is recommended you complete the caches in order, as some knowledge will build upon itself as the series progresses. Once you have successfully completed the exercises, you will be given coordinates to where the physical container is located. All containers are placed in a location with a relevant cybersecurity location nearby based on the cache. Some caches in this series have a field puzzle that you will need to complete in the field that are related to the exercises you completed on the site. You will need to complete the field puzzle in order to access the contents of the cache.


Congrats to VW_WLFZBRG for all three FTFs, three days in a row! Nice work!
