[BOUNTY] Create Comprehensive Threat Model Document #19
Description
[BOUNTY] Create Comprehensive Threat Model Document
Description
Identify and document all potential security risks, attack vectors, and mitigations for the privacy pool system. This is critical for security audits and safe deployment.
Scope
Document Structure
Create docs/THREAT_MODEL.md:
1. System Overview
- Trust assumptions
- Security goals
- Threat actors
2. Attack Vectors
Cryptographic Attacks:
- Proof forgery attempts
- Commitment collision
- Nullifier prediction
- Merkle proof manipulation
Smart Contract Attacks:
- Reentrancy
- Front-running
- Griefing attacks
- Storage manipulation
- Admin key compromise
Privacy Attacks:
- Timing analysis
- Amount correlation
- Address clustering
- Transaction graph analysis
Economic Attacks:
- Denial of service
- Resource exhaustion
- Fee manipulation
3. Mitigations
- For each attack: current mitigation
- Residual risks
- Recommended improvements
4. Known Limitations
- Privacy set size requirements
- Trusted setup (if applicable)
- Admin privileges
- Upgrade mechanisms
5. Audit Recommendations
- Critical areas for review
- Testing requirements
- Formal verification targets
6. Incident Response
- Emergency procedures
- Pause mechanism
- Fund recovery
- Communication plan
Acceptance Criteria
- Complete THREAT_MODEL.md file
- At least 20 attack vectors identified
- Mitigations for each attack
- Residual risks documented
- Reviewed by security expert
- References to code
- Incident response plan
Technical Notes
- Use STRIDE methodology
- Reference similar systems (Tornado Cash, Aztec)
- Consider Protocol 25 specific risks
- Document assumptions
