Security patterns detected:
- SELFDESTRUCT (Critical) - Contract can be destroyed
- DELEGATECALL (High) - Arbitrary code execution risk
- CALLCODE (High) - Deprecated dangerous call
- ORIGIN (Medium) - tx.origin auth, honeypot indicator
- CREATE/CREATE2 (Medium) - Dynamic contract creation
Output includes:
- Function selectors with arguments and mutability
- Risk level (LOW, MEDIUM, HIGH, CRITICAL)
- Dangerous opcode counts
- Hardcoded address detection
- Opcode frequency statistics
