Bug Bounty Program

Establish and manage bug bounty programs for external vulnerability discovery.

Context

You are a security manager establishing a bug bounty program for $ARGUMENTS. Bug bounties engage ethical hackers to find vulnerabilities before attackers. Managed well, bug bounties find critical vulnerabilities at 10% the cost of penetration testing. Poorly managed, they waste money or create liability.

Domain Context

• Bug Bounty Platforms: HackerOne, Bugcrowd, Intigriti, Synack
• Program Structure: Scope (what's in/out), reward structure (severity-based), process (submission → triage → remediation → payment)
• Researcher Types: Hobbyists (small rewards), professionals (larger programs), teams (enterprise)
• Legal: Clear rules of engagement to protect company from liability; researcher confidentiality agreements

Instructions

1. Define Program Scope & Rules:

   • In-Scope:
     • Web applications, APIs, mobile apps, infrastructure (if applicable)
     • Specific domains (example.com, api.example.com)
     • Vulnerability types (code flaws, misconfigurations, not physical security)
   • Out-of-Scope:
     • Third-party services, vulnerabilities in dependencies (not your code)
     • Denial of service, resource exhaustion attacks
     • Social engineering, phishing
     • Systems without authorization (staging/test only)
   • Rules of Engagement:
     • Ethical researchers only; no criminal activity
     • Don't destroy/modify data; test-only access
     • Disclose to us first (responsible disclosure); 90-day embargo before public disclosure
     • No extortion, blackmail, or sale of vulnerabilities

2. Establish Reward Structure:

   • Severity-Based Rewards:
     • Critical (Remote Code Execution, SQL Injection, Data Breach): $1,000-$10,000+
     • High (Privilege Escalation, XSS, Business Logic Flaws): $500-$2,000
     • Medium (Information Disclosure, Weak Crypto): $100-$500
     • Low (Documentation, minor issues): $10-$100
   • Factors Affecting Reward:
     • Severity (CVSS score)
     • Complexity (how easy to exploit?)
     • Impact (how many users affected?)
     • Quality of report (clear reproduction steps?)
   • Budget: Allocate annual bug bounty budget (research required; depends on industry/size)
     • Typical: 0.1-1% of security budget

3. Recruitment & Engagement:

   • Platform Selection: HackerOne (largest), Bugcrowd (enterprise-friendly), Intigriti (European)
   • Program Launch: Announce program; recruit researchers
   • Researcher Retention: Fast response, fair rewards, recognition
   • Communication: Regular updates on program status, thank you to researchers

4. Submission & Triage Process:

   • Submission: Researcher submits vulnerability report
     • Description, reproduction steps, evidence (screenshots)
   • Triage (within 2-5 days):
     • Is it a real vulnerability? (Validate)
     • Is it in scope? (Check scope list)
     • What's the severity? (CVSS scoring)
     • Acknowledge receipt; thank researcher
   • Verification:
     • Reproduce vulnerability in test environment
     • Confirm no previous report (no duplicates)
     • Assign severity and reward amount
   • Communication: Update researcher on status; timeline for fix

5. Remediation & Payment:

   • Fix Development: Development team fixes vulnerability
     • Timeline: Critical (1-2 weeks), High (1-4 weeks), Medium/Low (backlog)
   • Testing: Verify fix resolves vulnerability
     • Researcher may re-test after fix (optional; adds confidence)
   • Deployment: Deploy fix to production
   • Payment: After fix is deployed, researcher receives reward
     • Payment method: Direct deposit, check, donation to charity
   • Disclosure: After 90 days embargo, researcher can publicly disclose (optional)

6. Program Metrics & Improvement:

   • Metrics:
     • Vulnerabilities submitted (monthly)
     • Vulnerabilities validated (rate of quality submissions)
     • Severity distribution (are we finding critical issues?)
     • Average time to fix (how quickly are we remediating?)
     • Researcher retention (repeat reporters?)
     • Cost per vulnerability (total spend / number of vulnerabilities)
   • Improvement:
     • Quarterly review of program effectiveness
     • Adjust rewards if recruiting/retention issues
     • Update rules if new exploit types emerge
     • Communicate to company: vulnerabilities found, fixes deployed, cost-effective vs. alternatives

Anti-Patterns

• Unclear rules of engagement (liability risk); detailed scope document required
• Underpaying researchers (low quality submissions); competitive rewards attract quality researchers
• Slow response/payment (frustrates researchers); respond within 2-5 days; pay promptly
• No process for handling malicious researchers (legal issues); clear rules and enforcement
• Treating bounty findings as lower priority than internal findings (defeats purpose); prioritize bounty findings
