Nebula.NET — CLI (nebula)

Nebula.NET is an IL-level obfuscator and hardening tool for .NET assemblies, by Delta-1 Labs. It rewrites compiled .dll/.exe files to make reverse engineering harder while keeping the output behaviorally identical to the input.

This package installs the cross-platform command-line tool nebula as a .NET global/local tool. It runs on Windows, Linux, and macOS (.NET 8+), so it fits CI/CD pipelines and containers as well as the desktop.

Obfuscation raises the cost of reverse engineering; it is deterrence, not an unbreakable guarantee. Nebula.NET's design priority is that protected assemblies keep behaving exactly like the originals.

Install

dotnet tool install --global Delta1Labs.Nebula.Tool

(The package ID is Delta1Labs.Nebula.Tool; the installed command is nebula.)

Then:

nebula --version
nebula protect MyApp.dll --config nebula.json

What it does

  • Renaming of namespaces, types and members, with public-API preservation and reflection/serialization auto-detection.
  • Control-flow obfuscation, string/constant encryption, resource encryption, and whole-method encryption (anti-dump).
  • Reference (proxy-call) obfuscation to hide the call graph, built to resist automated deobfuscators such as de4dot.
  • Anti-debug / anti-tamper, environment & tampering-tool detection, metadata hardening, and strong-name / Authenticode signing (Authenticode is Windows-only).
  • Targets .NET Framework 4.8 → .NET 10 and .NET Standard 2.0/2.1 without changing the target framework.
