Information Gathering Using TheHarvester In Kali Linux


Information Gathering Using TheHarvester In Kali Linux

Today we will learn about Information Gathering using theHarvester in Kali Linux. Good information gathering can make the difference between a successful penetration test and one that has failed to provide maximum benefit to the client.

TheHarvester has been developed in Python by Christian Martorella. It is a tool which provides us information about e-mail accounts, user names and hostnames/subdomains from different public sources like search engines and PGP key server.
This tool is designed to help the penetration tester on an earlier stage; it is an effective, simple and easy to use. The sources supported are:
Google – emails, subdomains
Google profiles – Employee names
Bing search – emails, subdomains/hostnames, virtual hosts
Pgp servers – emails, subdomains/hostnames
LinkedIn – Employee names
Exalead – emails, subdomain/hostnames
New features:
Time delays between requests
XML results export
Search a domain in all sources

Virtual host verifier
