The FOCA is a network infrastructure mapping tool that can be used for OSINT. It can analyze metadata from various files, including doc, pdf and ppt files. FOCA can also enumerate users, folders, emails, software used, operating system, and other useful information. Customization options are also available in this OSINT tool. For more juicy information and details about insecure methods, there is a crawl option provided. The metadata can be extracted from a single file or from multiple files. The FOCA is thus a great tool in the reconnaissance phase, to extract information from the metadata.
