SpiderFoot is a free, open-source footprinting tool, enabling you to perform various scans against a given domain name in order to obtain information such as sub-domains, e-mail addresses, owned netblocks, web server versions and so on. The main objective of SpiderFoot is to automate the footprinting process to the greatest extent possible, freeing up a penetration tester’s time to focus their efforts on the security testing itself. SpiderFoot has written in Python and runs on Linux, *BSD and Windows. Download: SpiderFoot - Browse Files at SourceForge.net
