GitHub secret-scanning catches the largest providers (AWS, Stripe, Google Cloud, GitHub itself) and revokes on push. That leaves a long tail of less-scanned credentials — CRM tokens, marketing platform keys, e-sign vendor keys, custom-built internal API keys — that stay live in public repositories for months. Bots harvest new public commits within minutes; live credentials get weaponized within hours.
## Why attackers exploit it
Even non-cloud API keys map to lateral-movement paths. A CRM key exposes the customer list. A marketing platform key exposes engagement analytics and can be abused to send authentic-looking phishing from a trusted sender. A helpdesk key opens ticket history that names internal systems and privileged users.
## Remediation direction
Continuous scanning of public GitHub for corporate domain mentions, employee handles, and known internal project names — combined with a fast-path secret rotation runbook (identify credential owner, rotate, audit access logs for the exposure window). Longer term: mandatory pre-commit secret scanning on every corporate laptop and contractor workstation.
