Sputnik is a free web extension available for the Chrome platform. Developed by Mitchell Moser, this extension falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory.

Sputnik is designed to provide users with a convenient way to search for information using free Open Source Intelligence (OSINT) resources. With this extension, users can quickly and easily search for IPs, Domains, File Hashes, and URLs.

The usage of Sputnik is simple and intuitive. Users can select the artifact they wish to search, such as text or links, and right-click to access the extension's features. For text artifacts, a right-click will present various OSINT tools to choose from, and in most cases, users will be redirected straight to the results. For tools that require user interaction, such as captchas, the highlighted artifact will be saved to the clipboard and users will be directed to the submission page.

Sputnik is a valuable tool for individuals who rely on OSINT resources for their research or investigative work. With its ease of use and wide range of supported artifacts, this web extension is a must-have for anyone in need of efficient and effective OSINT searches.
