The TruffleHog Credential Leak Scanner skill uses TruffleHog by Truffle Security to scan for leaked secrets across a wide range of sources. Unlike simple regex-based scanners, TruffleHog combines pattern matching with active verification—it logs in with discovered credentials to confirm whether they are still live, providing a clear signal of present danger versus historical exposure.
What this skill actually does
TruffleHog classifies over 800 distinct secret types, including AWS access keys, Stripe API keys, database passwords, SSH private keys, OAuth tokens, and cloud provider credentials. For approximately 20 of the most commonly leaked credential types, TruffleHog goes beyond simple verification to perform full analysis: determining who created the secret, what resources it can access, and what permissions it holds. This transforms a raw finding into an actionable remediation ticket.
The scanner operates on Git repositories (scanning the full commit history, not just the current tree), GitHub and GitLab organizations, Docker images, S3 buckets, GCS buckets, Slack workspaces, Jira instances, Confluence spaces, local filesystems, and stdin. This breadth means the agent can audit not just source code but also the collaboration and infrastructure surfaces where secrets commonly leak.
TruffleHog outputs findings in JSON format with structured fields including the secret type, verification status (verified/unverified), source location, commit metadata, and for analyzed secrets, the full permission and resource inventory. In CI/CD pipelines, the official GitHub Action integrates with pull request checks. The tool supports baseline files to track known issues and avoid alert fatigue on accepted risks.
TruffleHog is written in Go, distributed via Homebrew, Docker, and direct binary download, and licensed under AGPL-3.0. It has active GitHub adoption, active weekly releases, and an engaged community on Slack and Discord. For teams managing any cloud infrastructure, this skill provides the detection layer that catches credential leaks before attackers do.
