Developed by James Forshaw

This is a small suite of tools to test various properties of sandboxes on Windows. Many of the checking
tools take a -p flag which is used to specify the PID of a sandboxed process. The tool will impersonate
the token of that process and determine what access is allowed from that location. Also it's recommended
to run these tools as an administrator or local system to ensure the system can be appropriately enumerated.

CheckExeManifest: Check for specific executable manifest flags.
CheckNetworkAccess: Check access to network stack.
NewProcessFromToken: Create a new process based on existing token.
TokenView: View and manipulate various process token values.
NtApiDotNet: A basic managed library to access NT system calls and objects.
NtObjectManager: A powershell module which uses NtApiDotNet to expose the NT object manager.
ViewSecurityDescriptor: View the security descriptor from an SDDL string or an inherited object.

The tools can be built with Visual Studio 2017. It's possible to also build NtApiDotNet and NtObjectManager
with .NET Core 2.0 by building the specific project files.
