What is seatbelt?

Seatbelt is a security tool that scans a Windows computer and quickly gathers a detailed snapshot of what's happening on that machine. It collects information about the system's configuration, network connections, running programs, and stored user credentials, presenting it all in one place. This is useful for both security teams trying to defend a network and offensive security professionals trying to find weak spots. The tool works by running a series of targeted checks that pull data from various corners of the Windows operating system. For example, it can look up basic system information, list all network connections, check which programs are set to launch automatically when the computer starts, or find saved cloud credential files. You can run it in broad modes, like asking it to check the "system" or the "user", or you can ask it to run very specific checks based on the exact information you need. When run with elevated or administrator-level permissions, it can pull even deeper data, such as security configurations from other user accounts on the same computer. Security professionals and system administrators are the primary users of this tool. A penetration tester (someone hired to break into a network to test its defenses) might run it right after gaining access to a machine to figure out what other systems they can reach or what sensitive files are stored locally. On the defensive side, an incident responder could use it to investigate a suspected compromise, checking what programs were recently running, what network connections were active, or what credentials an attacker might have accessed. The project is written in C# and built to run on the .NET framework, meaning it is designed specifically for Windows environments. The creators intentionally do not distribute pre-compiled versions of the software. Instead, anyone who wants to use it must compile or build the program themselves from the provided source code, which is a common practice in the security community to prevent attackers from hiding malware inside pre-packaged tools.
