In this six-hour Open Source Intelligence (OSINT) workshop, taught by a passionate social engineer and DerbyCon black badge recipient with a proven OSINT track record, you will obtain a fundamental understanding of OSINT. The legal and ethical considerations of collection and destruction of OSINT data will be discussed. From there, you will learn the offensive and defensive applications of OSINT information. In the next modules, "People OSINT" and "Business OSINT" as they relate to offensive attacks will be discussed. The workshop will wrap up with a two-hour "capture the flag."
