OSINT Reconnaissance Mapper

Open-Source Intelligence (OSINT) is the methodology of building a profile of an organization entirely from publicly available information, without ever making direct contact with its systems. This simulator visualizes four real passive-reconnaissance sources — DNS/subdomain enumeration, document metadata, employee social-media profiles, and public Certificate Transparency logs — as they each contribute fragments of information that merge into a single attack-surface map around a central target node. Because every source is public and no request ever reaches the target, this activity is undetectable to the organization being profiled, which is exactly why defenders run it against their own infrastructure first: to see what an outside observer would see before an attacker does.
