  • delivery-ci-storybook

A malware-laden version of the npm package delivery-ci-storybook has been identified and published to the npm registry. According to the GitHub Advisory (GHSA-vjwx-6r34-p6jx), any computer with this package installed or running should be considered fully compromised.\n\nThe advisory recommends that all secrets and keys stored on affected computers be rotated immediately from a different, uncompromised system. While the package should be removed, the advisory notes that full control of the computer may have been given to an outside entity, meaning removal of the package alone may not eliminate all malicious software that resulted from the installation.\n\nThis is a critical supply chain attack affecting the npm ecosystem, with potential for widespread impact across development environments and CI/CD pipelines that may have incorporated this package.
