de4dot is an open-source .NET deobfuscator and unpacker written in C# that restores packed and obfuscated .NET assemblies to near-original form. It supports many commercial obfuscators, decrypting strings, resources, and methods, removing anti-tamper code, and cleaning control flow.

Use cases

  • deobfuscate an obfuscated .NET assembly
  • unpack a packed .NET executable
  • decrypt strings in an obfuscated .NET app
  • analyze a .NET malware sample
  • remove anti-debug and tamper protection from an assembly
  • convert a wrapped PE exe back to a .NET exe
  • clean up spaghetti IL control flow for decompilation

When to choose

  • you need to reverse-engineer or audit an obfuscated .NET assembly
  • you want to restore readable code from assemblies packed with supported obfuscators like .NET Reactor or Dotfuscator
  • you do malware analysis of .NET binaries

When to avoid

  • you need to recover original symbol names - they are usually unrecoverable
  • you need support or updates for the latest obfuscator versions - the project has no support and releases stopped in 2020
  • you are working with non-.NET binaries
