Bug Bounty Program Setup

Immunefi Program Structure

program:
  name: "Protocol Name"
  website: "https://protocol.xyz"

  assets:
    smart_contracts:
      - type: "Smart Contract"
        target: "0x..."
        severity: "Critical"

    websites:
      - type: "Web Application"
        target: "https://app.protocol.xyz"
        severity: "High"

  severity_levels:
    critical:
      range: "$100,000 - $1,000,000"
      description: "Direct theft of funds, permanent freezing"
    high:
      range: "$10,000 - $100,000"
      description: "Theft requiring user action, temporary freezing"
    medium:
      range: "$1,000 - $10,000"
      description: "Griefing, DoS with medium impact"
    low:
      range: "$100 - $1,000"
      description: "Minor issues, informational"

  exclusions:
    - "Issues in test files"
    - "Third-party dependencies"
    - "Issues requiring admin key compromise"
    - "Front-running issues without significant impact"

Severity Classification

Vulnerability Triage Workflow

1. Initial Assessment

## Triage Checklist

- [ ] Report is within program scope
- [ ] Vulnerability is reproducible
- [ ] Impact assessment is accurate
- [ ] No duplicate of existing report
- [ ] Not a known issue or design decision

## Initial Classification

| Field | Value |
|-------|-------|
| Report ID | BB-2024-XXX |
| Submission Date | YYYY-MM-DD |
| Reporter | @handle |
| Asset Affected | Contract/​URL |
| Initial Severity | Critical/​High/​Medium/​Low |
| Status | Triaging |

2. Validation Process

# Clone and setup test environment
git clone <protocol-repo>
cd protocol

# Create PoC test
forge test --match-test test_VulnerabilityPoC -vvvv

# Run against mainnet fork
forge test --fork-url $MAINNET_RPC --match-test test_VulnerabilityPoC

3. Severity Adjustment

Consider:

• Likelihood: How likely is exploitation?
• Impact: What is the maximum damage?
• Complexity: What resources are needed?
• User Interaction: Does it require victim action?

Final Severity = Base Impact - Mitigating Factors + Aggravating Factors

Responsible Disclosure Process

Timeline

Day 0:    Report received
Day 1-3:  Initial triage and acknowledgment
Day 3-7:  Validation and severity confirmation
Day 7-14: Fix development
Day 14-21: Fix review and testing
Day 21-30: Coordinated disclosure preparation
Day 30+:  Public disclosure (if agreed)

Communication Templates

Acknowledgment:

Subject: [BB-XXXX] Report Acknowledged

Dear Security Researcher,

Thank you for your submission to our bug bounty program. We have received
your report and assigned it reference number BB-XXXX.

Our security team is currently reviewing your submission. We will provide
an initial assessment within 3 business days.

Timeline:
- Initial response: 24-72 hours
- Severity assessment: 3-7 days
- Fix timeline: TBD based on severity

Best regards,
Security Team

Severity Confirmation:

Subject: [BB-XXXX] Severity Assessment Complete

Dear Security Researcher,

After thorough review, we have assessed your vulnerability report:

Severity: [CRITICAL/​HIGH/​MEDIUM/​LOW]
Bounty Range: $X - $Y
Fix Timeline: X days

[Details of assessment]

Next Steps:
1. Fix development (ETA: X days)
2. Fix verification with your input
3. Coordinated disclosure discussion

Best regards,
Security Team

Bounty Calculation

Factors

const bountyCalculation = {
  baseBounty: getSeverityBase(severity), // Based on tier

  adjustments: {
    qualityOfReport: 1.0 - 1.5,    // Well-documented PoC
    impactAccuracy: 0.8 - 1.2,     // Accurate impact assessment
    firstReporter: 1.0,            // First to report
    duplicatePartial: 0.0 - 0.5,   // Partial duplicate
    responsibleBehavior: 1.0 - 1.2 // No public disclosure
  },

  calculate() {
    return this.baseBounty *
           this.adjustments.qualityOfReport *
           this.adjustments.impactAccuracy *
           this.adjustments.responsibleBehavior;
  }
};

Payment Process

1. Verify Identity: KYC requirements for large bounties
2. Payment Method: Crypto (USDC, ETH) or fiat
3. Tax Documentation: W-9 (US) or W-8BEN (non-US)
4. Confirmation: Receipt and acknowledgment
