Open-source intelligence (OSINT) involves gathering information from publicly available sources. There is information available on businesses, organizations, people, and website domains. Here are some techniques that can be used:

• Google Dorks: This technique uses advanced search operators to find specific information on the web. For example:
  • site: example.com “search term” to search within a specific site.
  • filetype: pdf “search term” to find PDF documents containing the search term.
• Social Media Analysis: You can gather a lot of information from social media profiles. Look for public posts, comments, likes, and shared content. Tools like Social Searcher can help you search across multiple platforms.
• Public Records: Many government websites provide access to public records, such as property records, court records, and business registrations. Websites like the local county clerk’s office or state business registry can be useful.
• Reverse Image Search: Use tools like Google Images or TinEye to find where an image has been posted online. This can help verify the authenticity of photos or find more information about them.
• WHOIS Lookup: This tool allows you to find information about the ownership of a domain name. Websites like WHOIS.net can provide details about the domain registrant.
• People Search Engines: Websites like Pipl, Spokeo, or Whitepages can help you find information about individuals, such as contact details, addresses, and social media profiles.

OSINT techniques can help you gather a wide range of information from publicly available sources. Always remember to use this information ethically and respect privacy laws. One common use case of OSINT is discovering what information about yourself is available. These techniques help you learn just how much information you are allowing into public sources.
