Exposed Cloud Credentials in Code Repositories: How Attackers Find Them and How to Stop Them

Developers frequently commit API keys, cloud credentials, or private keys into code repositories, where automated tools can detect them within minutes. Attackers use secret scanners, GitHub search queries, and mass-scanning services to locate these exposed secrets. Compromised credentials can lead to data theft, unauthorized cloud spending, lateral movement into internal systems, and service impersonation. Recommended defenses include keeping secrets out of source code, using pre-commit and CI secret scanning, and storing production secrets in a vault. If a secret leaks, it should be revoked and rotated immediately, and the repository history must be scrubbed because deleting the file alone is insufficient.
