Control Flow Obfuscation Algorithm

The Control Flow obfuscation algorithm transforms the Intermediate Language (IL) code within an assembly. It distorts and reorders the code, inserting decoy branch instructions. This alters the code's structure while preserving its semantics.

Applying this algorithm expands the size of the resulting assembly. It effectively converts assembly method implementations into "spaghetti code," making analysis significantly more challenging for humans and decompilation tools.

Purpose of Control Flow Obfuscation

Control Flow obfuscation aims to prevent decompilers and deobfuscators from accurately interpreting the code. It hinders reverse engineering by scrambling the code of .NET methods (functions and procedures).

Considerations for Use

If a high level of code protection is unnecessary, consider disabling this feature to minimize the output executable size.

Infringement Prevention

Infringement can occur through various means, including:

- Unauthorized use of copyrighted or trademarked material
- Creation of unauthorized derivatives or inferior versions of original products
- Exploitation of a company's brand for promotion or sales
- Misappropriation of trade secrets

To prevent infringement, clearly establish intellectual property rights by issuing cease-and-desist requests to infringing parties. These requests should serve as warning notices, asserting ownership and demanding cessation of unauthorized activities related to the reproduction or use of the infringed property.
