OSINT
The collection of information from public sources, useful to attackers and defenders alike.
OSINT (open source intelligence) consists of gathering freely accessible information: websites, social networks, public registers, old leaks. Attackers use it to prepare a credible targeted attack. Defenders use it to measure their own exposure and reduce what is needlessly lying around online.
