Open-Source Intelligence (OSINT) refers to the collection and analysis of any information about an individual or organization that can be legally gathered from free, public sources.
While much of the information comes from the internet and can include usernames, social networks profiles, IP addresses, and public records, it also includes data found in images, videos, webinars and public speeches. OSINT operations require no specialized skills and can be conducted by anyone including IT and security teams or attackers who use a variety of techniques to sift through visible data to find the opening they need.
