The npm package calmora was identified as containing malware. According to the GitHub Security Advisory, any computer that has 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 resulting from the installation.\n\nThis represents a critical supply chain compromise affecting the npm ecosystem.
