OSINT

======

Here are some quizzes for working on your OSINT skills.

There are two great CTF quizzes produced by @cybersoc at Cardiff University: Cyber detective and Cyber investigator.

There are also the ongoing @quiztime geolocation puzzles on Twitter, some challenges from @OSINTDOJO and several quizzes from @Sector035 that run over email: 2019 and 2020 (and the fiendishly difficult 2017 quiz).

There’s also this series of challenges at sourcing.games.
