GasMask strives to be an all-in-one Information Gathering (OSINT) tool.


It is an Open-Source Intelligence (OSINT) tool that helps you effectively gather information from publicly available sources.

GasMask is useful for Penetration Testers and Red Teams that wish to collect as much information as possible about a target client.

Information gathering is the most critical step to discover preliminary information about the systems, their software and the people involved with the target.

You can download the GasMask tool from TwelveSec’s github page.
