Background

Open-Source Intelligence Tools and Resources

A curated list of Open-Source Intelligence tools and resources. Open-Source Intelligence (OSINT) is intelligence collected from publicly available sources. In the intelligence community (IC), the term “open” refers to overt, publicly available sources (as opposed to covert or clandestine sources)

Credits: This list and tools are sourced and grouped from various locations and public collections on the web. Feel free to "search engine" the tool or resource to find the original owner. Without contributors, we would not have toolkits for our line of work. Nevertheless, the usual security precautions apply: always experiment on a dedicated desktop or laptop PC, and be sure to firewall any devices you use for research and investigative purposes.
