Open Source Intelligence (OSINT)

Open-source intelligence (OSINT) involves gathering and analyzing publicly available information to uncover useful insights. A social media post, restaurant review, or career profile may seem harmless on its own, but together these details can reveal someone’s routines, relationships, location, and more. Oversharing can make it easier for others to craft convincing scams, guess account recovery answers, or discover private details.

In this challenge, investigate a fictional person across several example sites to see how scattered clues connect. As you explore, consider: What does your own digital footprint reveal, and what could you choose to keep private?
