sherlock <username>

Search for a username across hundreds of social networks and services with Sherlock, mapping the target's online presence.

Run it in the OSINT phase when you want to map a user's presence: Sherlock queries services (social networks, forums, platforms) with the username and reports existing profiles — with the URL of each one. It's the reference username OSINT tool (from Sherlock Project): the target's online presence in one sweep. In reconnaissance (and red teaming), Sherlock gives the map of the target's accounts — the surface for targeted phishing, platform enumeration, and cross-referencing with leaked data.

Don't use it as identity verification: a username's presence on a service doesn't confirm it's the same person — homonyms and fake profiles generate false positives; verify each finding (content, dates, cross-references). The sweep generates traffic to services (and some block it): space out mass queries. And watch out: the tool depends on the maintenance of the site list (service selectors change): keep the version up to date. For cross-referencing with leaked data (breaches), use breach search tools; Sherlock is current presence.
