AtlasCTF
A collection of OSINT and geolocation challenges
AtlasCTF is an open, growing archive of OSINT challenges focused on geolocation, with difficulties ranging from beginner to expert.
There’s no start or finish date, so you can jump in anytime and work through the challenges at your own pace.
Play your way
Solve on your own or team up with others. AI, scripts, maps, search engines and any other tools that help you solve a challenge are welcome. Experimenting and learning are part of the fun.
A heads-up about writeups
Some challenges may already have writeups or solutions posted online. Try to avoid those while solving so you can work through the clues and make the discoveries yourself.
Learning comes first
AtlasCTF is about learning and sharing knowledge. It’s not an official competition, and the scoreboard is simply there for motivation and to help you track your progress.
The collection started with contributions through the Hacktoria community and its 24/7 OSINT challenges.
