Dr Hans-Jakob Schindler and Alexander Ritzmann are joined by Elena Martynova to explore how Open-Source Intelligence (OSINT) has reshaped the fight against extremism—revealing hidden networks, exposing propaganda, and bringing new information to conflict zones. Yet the same open data—and now artificial intelligence—that empowers investigators is increasingly being weaponized by extremist actors. Together, they unpack how OSINT has become both a vital tool and a contested battleground. Elena is an EU GLOCTER PhD Candidate on secondment to CEP.

This discussion is based on Elena's blog series for CEP on various aspects of OSINT.
