A critical malware incident was identified in the npm package tailwindcss-anim. According to the GitHub Advisory (GHSA-m326-xg22-g2fx), 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 supply chain compromise through a malicious package distribution in the npm ecosystem.
