The Solution

Regenerate API keys immediately if exposed, use OAuth for integrations, implement IP whitelisting, and never commit .netrc files.

Best Practices

  • Use Encrypted Storage: Never store credentials in plain text. Use zero-knowledge encryption like CloakBin.
  • Rotate Keys Regularly: Change API keys and passwords frequently, especially after incidents.
  • Limit Access: Use environment variables and secrets managers. Never hardcode credentials.
  • Monitor for Leaks: Use GitHub secret scanning and other monitoring tools.
