So, you want to automate your security assessment (beyond pentesting)…

Automatic Security Assessment of GitHub Actions Workflows (

After my last post, and the visit to the workshop at MDU, I realized that there are a few tools that can be used automatically already now. So, this paper presents one of them.

What is interesting about this tool is that it uses github workflows, so it’s compatible with many modern CI/CD pipelines. The tool analyzes worflows and looks for security vulnerabilities. For example, if you keep sensitive information in a plain text file that is used in the workflow (secrets), or checks if the workflow enforces the “least privilege” principle.

The implementation of the tool is OSS; can be found on github here: Mobile-IoT-Security-Lab/GHAST: GitHub Actions Security Tester

I need to test it as it looks very interesting. Maybe I can use this tool on some of the company’s workflows to test their exploitability score?
