Seatbelt
Seatbelt is a C# project that performs a number of security oriented host-survey "safety checks" relevant from both offensive and defensive security perspectives.
@andrewchiles' HostEnum.ps1 script and @tifkin_'s Get-HostProfile.ps1 provided inspiration for many of the artifacts to collect.
@harmj0y and @tifkin_ are the primary authors of this implementation.

Command Line Usage
Note: searches that target users will run for the current user if not-elevated and for ALL users if elevated.
A more detailed wiki is coming...
Command Groups
Note: many commands do some type of filtering by default. Supplying the -full argument prevents filtering output. Also, the command group all will run all current checks.
For example, the following command will run ALL checks and returns ALL output:
Seatbelt.exe -group=all -full
system
Runs checks that mine interesting data about the system.

Command Arguments
Command that accept arguments have it noted in their description. To pass an argument to a command, enclose the command an arguments in double quotes.
For example, the following command returns 4624 logon events for the last 30 days:
Seatbelt.exe "LogonEvents 30"
The following command queries a registry three levels deep, returning only keys/valueNames/values that match the regex .*defini.*, and ignoring any errors that occur.
Seatbelt.exe "reg \"HKLM\SOFTWARE\Microsoft\Windows Defender\" 3 .*defini.* true"
Output
Seatbelt can redirect its output to a file with the -outputfile="C:\Path\file.txt" argument. If the file path ends in .json, the output will be structured json.
For example, the following command will output the results of system checks to a txt file:
Seatbelt.exe -group=system -outputfile="C:\Temp\system.txt"
Remote Enumeration
Commands noted with a + in the help menu can be run remotely against another system. This is performed over WMI via queries for WMI classes and WMI's StdRegProv for registry enumeration.
To enumerate a remote system, supply -computername=COMPUTER.DOMAIN.COM - an alternate username and password can be specified with -username=DOMAIN\USER -password=PASSWORD
For example, the following command runs remote-focused checks against a remote system:
Seatbelt.exe -group=remote -computername=192.168.230.209 -username=THESHIRE\sam -password="yum \"po-ta-toes\""
Building Your Own Modules
Seatbelt's structure is completely modular, allowing for additional command modules to be dropped into the file structure and loaded up dynamically.
There is a commented command module template at .\Seatbelt\Commands\Template.cs for reference. Once built, drop the module in the logical file location, include it in the project in the Visual Studio Solution Explorer, and compile.
Compile Instructions
We are not planning on releasing binaries for Seatbelt, so you will have to compile yourself.
Seatbelt has been built against .NET 3.5 and 4.0 with C# 8.0 features and is compatible with Visual Studio Community Edition. Simply open up the project .sln, choose "release", and build. To change the target .NET framework version, modify the project's settings and rebuild the project.
