## Detection Methodology

### Heuristic Analysis

1. **Memory Layout Analysis**
   - RWX region detection
   - Memory gap analysis
   - Region size anomalies

2. **Behavioral Patterns**
   - Thread creation patterns
   - Hook installation monitoring
   - Process lifecycle anomalies

3. **Signature Matching**
   - Known shellcode patterns
   - Malware family signatures
   - API usage fingerprints

### Confidence Scoring

- **0.9-1.0**: Very High - Multiple strong indicators
- **0.7-0.8**: High - Clear malicious patterns
- **0.5-0.6**: Medium - Suspicious but may be legitimate
- **0.3-0.4**: Low - Anomalous but likely false positive
- **0.0-0.2**: Very Low - Minimal suspicious activity
