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
