Sylvain Hajri is a leading voice in the field of Open Source Intelligence (OSINT), regularly invited by Europol, Interpol, and the Economic Warfare School to train and brief security professionals on emerging digital threats, including internal fraud, DPRK IT infiltration, and cybercrime.

Threat actors, from sophisticated DPRK IT worker cells to cunning insider threats and fraud rings, are in a constant state of evolution. Our investigative methods must evolve faster. In this session, Sylvain Hajri will move beyond conventional OSINT to reveal powerful, lesser-known techniques born from focused research and development.

Prepare to see the investigation unfold in real-time as Hajri demos Epieos, a specialized tool designed to meet these modern challenges head-on. He will showcase new, actionable capabilities that empower law enforcement and security professionals to cut through digital noise and expose complex criminal networks. This talk is not just a theoretical overview; it's a practical demonstration of next-generation tools and strategies that can be immediately applied to your most complex cases.

Since 2020, he has led the development of Epieos, an advanced OSINT solution trusted by U.S. agencies, Fortune 100 companies, and over 5 million users worldwide.
Epieos supports high-impact investigations into cybercrime, fraud, espionage, and terrorism, delivering actionable intelligence that has already contributed to the resolution of numerous cases.

He is also co-founder of OSINT-FR (18,000+ members) and organizer of the OSINT Village at leHack, one of Europe’s foremost hacking events.
