Code Watermark

Obfuz injects special metadata and specific instruction sequences into obfuscated assembly metadata to form identifiable watermark features.

Goals of Code Watermarking​

  • Copyright identification: Prove that the code was generated or authorized for release by you.
  • Source tracing: Used to mark code generated by different users or different authorization parties, so the source can be traced if leaked.
  • Anti-obfuscation resistance: Even if the code undergoes re-obfuscation or partial restoration, the watermark can still be preserved to some extent.

Settings​

ObfuzSettings.WatermarkSettings contains related settings, detailed documentation can be found in Configuration.

Watermark Identification Categories​

Inject the following special watermark identifiers:

  • Inject watermark hash signatures into rva data
  • Generate types, functions, and fields with special rules
  • Inject specific instruction sequences into code bodies
