# Contractors Secure GitHub Actions Credentials

Wiz Research reports that the Gheist campaign compromised more than 850 GitHub accounts and created over 13,500 malicious branches to expose repository, environment, and potentially self-hosted-runner credentials. Government contractors and other organizations using GitHub Actions may face risks to development systems and connected cloud environments. The report identifies no contract award or procurement opportunity, but the incident is relevant to contractor cybersecurity and supply-chain risk management.

- Organizations using GitHub Actions should inspect for the branch and workflow indicators identified in the report, revoke exposed tokens, and rotate accessible secrets.
- Review cloud audit logs for signs that exposed credentials were used; this can help assess whether development-system access extended to connected environments.
- Procurement and security teams can use the incident to assess how contractors protect source-code workflows, credentials, and self-hosted runners in their delivery environments.
