The npm package node-core-libs was found to contain malware. According to the GitHub Advisory (GHSA-6vr2-5hpq-589c), 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 represents a critical supply chain compromise affecting the npm ecosystem.
