Infrastructure & Network Reconnaissance
SpiderFoot
Automates threat-intel and reconnaissance gathering.
SpiderFoot is an open-source intelligence automation tool that aggregates data from numerous public sources to map out an entity's digital footprint. It is commonly used by security professionals and researchers to conduct automated reconnaissance on domains, IP addresses, and email addresses for threat intelligence and vulnerability assessment purposes.
Dual-use tool. This is capable of legitimate research (journalism, security, due diligence) and of harassment or stalking. Listing it here is not an endorsement of either use.
