## ๐ฏ Purpose & Scope
Establish a comprehensive threat model for the Black Trigram Korean martial arts combat simulator. This systematic threat analysis integrates multiple threat modeling frameworks to ensure proactive security through structured analysis of the frontend-only educational gaming platform.
### **๐ Transparency Commitment**
This threat model demonstrates **๐ก๏ธ cybersecurity consulting expertise** through public documentation of advanced threat assessment methodologies for browser-based gaming platforms, showcasing our **๐ competitive advantage** via systematic risk management and **๐ค customer trust** through transparent security practices.
_โ Based on Hack23 AB's commitment to security through transparency and excellence_
### **๐ Framework Integration**
- **๐ญ STRIDE per architecture element:** Systematic threat categorization for frontend components
- **๐๏ธ MITRE ATT&CK mapping:** Client-side attack technique integration
- **๐๏ธ Asset-centric analysis:** Educational content and user experience protection
- **๐ฏ Scenario-centric modeling:** Real-world gaming platform attack simulation
- **โ๏ธ Risk-centric assessment:** Educational value and cultural sensitivity impact
### **๐ฏ Multi-Strategy Threat Modeling Integration**
This threat model implements all five strategies defined in [Hack23 AB Threat Modeling Policy ยง4](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Threat_Modeling.md#threat-modeling-strategies):

### **๐ Kill Chain Disruption Analysis**
Following [Hack23 AB Threat Modeling Policy ยง4.1.4](https://github.com/Hack23/ISMS-PUBLIC/blob/main/Threat_Modeling.md) โ mapping defensive controls to each Cyber Kill Chain phase for the frontend-only architecture:
| Kill Chain Phase | Black Trigram Attack Vector | Defensive Control | Detection Mechanism | Disruption Effectiveness |
|---|---|---|---|---|
| **1. Reconnaissance** | Scanning for frontend vulnerabilities, technology fingerprinting | Minimize exposed metadata, generic error pages, security headers | Web analytics anomaly detection, CDN access logs | [](https://github.com/Hack23/ISMS-PUBLIC/blob/main/CLASSIFICATION.md) |
| **2. Weaponization** | Crafting XSS payloads, malicious asset packages, supply chain exploits | N/A โ occurs externally; mitigate via proactive dependency monitoring | Threat intelligence feeds, CVE monitoring, GitHub Security Advisories | [](https://github.com/Hack23/ISMS-PUBLIC/blob/main/CLASSIFICATION.md) |
| **3. Delivery** | Compromised CDN assets, malicious NPM packages, phishing links | CSP headers, SRI validation, dependency pinning, SLSA attestations | Dependency scanning (Dependabot), SRI mismatch alerts, CDN integrity monitoring | [](https://github.com/Hack23/ISMS-PUBLIC/blob/main/CLASSIFICATION.md) |
| **4. Exploitation** | XSS execution, DOM manipulation, WebGL/Canvas exploits | React security patterns, strict CSP, input sanitization, Three.js security context | CSP violation reporting, error boundary triggers, performance anomaly detection | [](https://github.com/Hack23/ISMS-PUBLIC/blob/main/CLASSIFICATION.md) |
| **5. Installation** | Persistent browser storage manipulation, service worker hijacking | Session-only design, no persistent data, minimal browser API permissions | Storage quota monitoring, service worker integrity validation | [](https://github.com/Hack23/ISMS-PUBLIC/blob/main/CLASSIFICATION.md) |
| **6. Command & Control** | Exfiltration via DNS tunneling, WebSocket abuse, beacon injection | No outbound data channels by design, strict CORS, no telemetry collection | Network monitoring (CDN logs), CORS violation alerts | [](https://github.com/Hack23/ISMS-PUBLIC/blob/main/CLASSIFICATION.md) |
| **7. Actions on Objectives** | Content defacement, cultural misrepresentation, user device exploitation | Content integrity validation, cultural review process, browser sandbox | Content monitoring, community reporting, performance budget alerts | [](https://github.com/Hack23/ISMS-PUBLIC/blob/main/CLASSIFICATION.md) |
**Key Insight:** Black Trigram's frontend-only architecture provides natural kill chain disruption at phases 5-6, as there is no persistent installation vector and no command & control channel by design. The primary attack surface is concentrated at phases 3-4 (delivery and exploitation), where CSP, SRI, and supply chain security controls provide strong defense.
