NetSniffer: Context Menu OSINT is a Chrome add-on developed by PyKestrel. It is a free tool designed to help security researchers leverage OSINT (Open Source Intelligence) APIs directly from their Chrome context menu. With this tool, users can quickly access popular security tools, speeding up response and research times.

One of the main features of NetSniffer is the ability to research domains and IP addresses on Cisco Talos or Virus Total with just a right-click. This allows users to gather valuable information about potential threats or suspicious entities without leaving their browser.

In addition to the integration with Cisco Talos and Virus Total, NetSniffer also offers integration with other popular tools. The developers continue to update the tool, adding more functionality and expanding the list of supported integrations.

It's important to note that NetSniffer: Context Menu OSINT is designed for research purposes only. It provides security researchers with a convenient way to access OSINT APIs directly from their browser, enhancing their capabilities and efficiency.
