Recently, CodeShip, a CI/CD service, reported a security incident: a database containing their production data had been exposed for over a year. CodeShip requests its customers to reset all keys, deployment credentials, and authorization tokens that may have been exposed.
Although Healthchecks.io is not using CodeShip directly, CodeShip had access to a Bitbucket source code repository containing various secrets that the Healthchecks.io production environment uses. While there are no signs of any unauthorized access, we have taken several precautions: the secrets have been reset to new values, the secrets are now being stored in an encrypted form, and CodeShip's access to the Bitbucket repository has been revoked.
