Code Obfuscation / Deobfuscation

Obfuscation Techniques

1. Control flow flattening 鈥?transform if/while/for into switch-based dispatcher
2. String encryption 鈥?XOR/AES strings, decrypt at runtime
3. Instruction substitution 鈥?replace simple ops with complex equivalents
4. Opaque predicates 鈥?always-true/false conditions that look complex
5. Dead code insertion 鈥?unreachable blocks that confuse static analysis
6. Function splitting 鈥?break functions into fragments, reorder randomly
7. Constant obfuscation 鈥?MBA (Mixed Boolean-Arithmetic) expressions

Deobfuscation Techniques

1. Pattern matching 鈥?recognize standard flattening dispatch patterns
2. Symbolic execution 鈥?angr/MIAsM to recover original control flow
3. Dynamic analysis 鈥?trace execution, record actual path
4. Taint analysis 鈥?track obfuscated values to source
5. LLVM optimization passes 鈥?run -O3 on lifted IR

Execution

When triggered:

1. Analyze target for obfuscation indicators (entropy, CFG complexity)
2. Identify obfuscation type(s)
3. Apply matching deobfuscation technique
4. Or: apply obfuscation to protect sensitive code
5. Write result to disk
