GitHub Push Secret Scan to Auto-Revoke and Page

Watches GitHub push events for committed credentials, immediately revokes the leaked AWS key, and pages on-call with the offending commit and author.

What it does

Catches secrets the moment they land in a GitHub repo, kills the credential before it can be abused, and gets a human on it. It turns a silent leak into a contained, tracked incident within seconds of the push.

When to use it

Use it on any repo where developers can push directly and a leaked AWS access key would be an emergency. Best paired with GitHub secret scanning push protection as a backstop rather than the only line of defense.

How it works

  1. 1A GitHub push webhook fires with the new commits and diffs.
  2. 2A scan step inspects added lines for AWS key patterns (AKIA-prefixed IDs plus a paired secret).
  3. 3A logic gate decides: if a high-confidence match is found, continue to revocation; otherwise exit quietly.
  4. 4The matched IAM access key is deactivated through the AWS API so it can no longer authenticate.
  5. 5PagerDuty raises a high-urgency incident tagged with the repo, commit SHA, and author.
  6. 6A Slack alert posts to the security channel with a remediation checklist and links back to the commit.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect GitHubRepos, issues, pull requests, actions.
  2. 2
    Connect AWS S3Buckets, objects, signed URLs.
  3. 3
    Connect PagerDutyIncidents, on-call, escalations.
  4. 4
    Connect SlackChannels, DMs, threads, mentions.
  5. 5
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  6. 6
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  7. 7
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
