Metagoofil is a tool for extracting metadata of public documents (pdf,doc,xls,ppt,etc) availables in the target websites.This information could be useful because you can get valid usernames, people names, for using later in brute force password attacks (vpn, ftp, webapps), the tool will also extracts interesting “paths” of the documents, where we can get shared resources names, server names, etc.
The tool first perform a query in Google requesting different file types that can have useful metadata (pdf, doc, xls,ppt,etc), then will download those documents to the disk and extracts the metadata of the file using specific libraries for parsing different file types (Hachoir, Pdfminer, etc)
