theHarvester : Gather e-mail addresses, Open ports, and more

theHarvester is an open-source tool developed in python. the objective of this tool is to gather emails, subdomains, hosts, employee names, open ports, and banners from different sources like search engines (Google, bing, duckduckgo, …)

this tool was made to help penetration testers in the early stage understand the customer footprint on the internet. this tool is also useful for anyone to know what an attacker can see about their organization.
