## What it is
GadgetToJScript is a C# tool that generates .NET BinaryFormatter serialized gadget payloads embedded in JS/VBS/VBA/HTA scripts, triggering .NET assembly load and execution on deserialization. It is designed for red team weaponization of WSH scripts, including AMSI and .NET 4.8+ type-check bypasses.

## Use cases
- generate jscript payloads that execute a .NET assembly via BinaryFormatter deserialization
- weaponize WSH scripts for red team initial access
- bypass AMSI and .NET 4.8 assembly load controls in script payloads
- create VBA/VBS droppers that run shellcode loaders
- automate registration-free .NET COM activation in scripts

## When to choose
- you are a red teamer needing serialized .NET gadget payloads in JS/VBS/VBA scripts
- you need to bypass .NET 4.8+ ActivitySurrogateSelector type checks
- you target Windows environments with .NET Framework 3.5 through 4.8+

## When to avoid
- you need a general-purpose deserialization vulnerability scanner
- you want defensive detection tooling rather than offensive payload generation
- your targets are non-Windows or non-.NET environments

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: security, serialization, cryptography
- domain: security, penetration-testing, windows
- platform: windows, dotnet, cli
