DETECT SECRETS IN GITLAB CI LOGS USING GGSHIELD AND BRING YOUR OWN SOURCE

Summary from the TLDR InfoSec newsletter

GitGuardian demonstrates how to automatically scan GitLab CI/CD pipeline logs for secrets using ggshield and their Bring Your Own Source initiative, addressing a critical but often overlooked attack vector where sensitive data like environment variables, API responses, and temporary credentials are exposed in build logs. The solution involves creating a custom Docker image with enhanced ggshield capabilities, configuring secure token storage via HashiCorp Vault, and implementing an automated scanning script that processes all pipeline job logs and creates incidents in the GitGuardian dashboard. This approach provides comprehensive secrets detection across the entire DevOps lifecycle, catching runtime secrets that traditional source code scanning misses while maintaining zero friction for developers.
