How do API keys get exposed?

Pushed to GitHub, hardcoded in source, logged to console, stored in config files. GitHub scanning catches some, but many slip through.

Can hackers find my API keys on GitHub?

Yes—easily. Tools like GitHound, truffleHog scan GitHub 24/7. Harvested within minutes of exposure.

Cryptocurrency mining, spam, cloud resource theft, data exfiltration, credit card fraud. Costs can hit $50K+ quickly.

Environment variables in .env files (gitignored). Secret managers like AWS Secrets Manager for production.

Rotate immediately. Delete old key. Generate new one. Update apps. Check logs.

More secure than hardcoding, but not perfect. Still visible in process lists. Use secret managers for high-security scenarios.

Pre-commit hooks with truffleHog. CI/CD scanning. Regular repo audits for API_KEY, SECRET, TOKEN.
