🛡️ Ethical Investigation Guidelines

  • Authorization: Only search data for which you have explicit permission or are conducting authorized penetration testing.
  • Avoid PII Exposure: Never store, process, or disseminate Personally Identifiable Information (PII) discovered in leaks.
  • Reporting: If you discover a significant breach involving sensitive data, follow responsible disclosure practices.
  • Operational Security (OPSEC): Never perform searches for leaked credentials using your own actual email addresses or passwords. Use sanitized environments.

🔍 Investigative Methodology

  1. Indicator Analysis: Start by identifying identifiers (email, username, domain, hash).
  2. Contextual Search: Use intelligence platforms to determine the scope of the breach and the nature of the exposed data.
  3. Pattern Identification: Look for password reuse patterns, common naming conventions, or associated secondary email accounts.
  4. Verification: Validate findings against legitimate data sources. Do not assume leaked data is current or accurate.

📝 Researcher's Checklist

  • Is my investigative environment isolated (VM/Docker)?
  • Have I confirmed my legal/ethical authorization to access this data?
  • Am I using non-identifiable test accounts for initial searches?
  • Have I sanitized any notes to ensure no PII is saved locally?
