# Security Disclosure Recommendation: Check for Anomalous GitHub Access

> This guide is part of Railway's response [to the security disclosure published on October 21, 2026](https://blog.railway.com/p/security-disclosure-wednesday-october-21st).

*If you connect GitHub to Railway, review your security log, authorized apps, and keys for access you didn't grant, then confirm nothing unexpected reached your deployments.*

If a GitHub token, SSH key, or password stored in Railway variables may have been exposed, or Railway deployed a commit you don't recognize, check for anomalous GitHub access. Work through the GitHub checks first, then the Railway checks. Revoke anything you don't recognize as you go.

## Review your personal account

GitHub logs security-relevant actions on your account for 90 days, and every integration or key.

1. Open your [security log](https://github.com/settings/security-log). Filter with `operation:authentication` for sign-ins and `operation:access` for resource access. The `oauth_authorization`, `public_key`, `personal_access_token`, and `repo` categories cover the common ways an attacker gains persistence. See [Reviewing your security log](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/reviewing-your-security-log).
2. Review [authorized OAuth apps](https://github.com/settings/applications) and [authorized GitHub Apps](https://github.com/settings/apps/authorizations). Revoke anything you don't recognize, and anything with private repository access that doesn't need it.
3. Review [SSH and GPG keys](https://github.com/settings/keys) and delete keys you didn't add.
4. Review [personal access tokens](https://github.com/settings/tokens), including fine-grained tokens. Delete tokens you don't recognize and regenerate all tokens

## Review your organization

Organization owners have a separate audit log that covers every member's actions on organization resources for 180 days.

1. Open the organization's **Settings**, expand **Logs**, and click **Audit log**. See [Reviewing the audit log for your organization](https://docs.github.com/en/organizations/keeping-your-organization-secure/managing-security-settings-for-your-organization/reviewing-the-audit-log-for-your-organization).
2. Export the filtered log as JSON or CSV before you revoke anything, so the evidence survives credential deletion.
3. Review **Third-party access** in the organization's settings for OAuth apps and GitHub Apps you didn't approve.
4. For each affected repository, review **Deploy keys**, **Secrets and variables**, **Webhooks**, and **Collaborators** under the repository's **Settings**. An attacker with push access can add a webhook or secret that outlives a password reset.
