Rotate your CircleCI secrets immediately
CircleCI has just announced a security breach: https://circleci.com/blog/january-4-2023-security-alert/
I’m seeing reports of people seeing cloud credentials being used from an unknown source.
A best practice is to use OIDC for your CI provider to connect to your cloud instead of static credentials. These short-lived tokens are far more secure, especially when these situations come up.
Something else you can choose to do is use a different secret store for your secrets. I’ve had some good success using AWS Secrets Manager with a GitHub action that pulled in secrets. The only thing that is exposed in GitHub Actions was the short-lived token from OIDC.
