The npm package tailwindcss-animatecss-latest was found to contain malware. According to the GitHub Advisory (GHSA-cjj7-4xf8-fgf8), any computer with this package installed or running should be considered fully compromised.\n\nThe advisory recommends immediate action: all secrets and keys stored on affected computers should be rotated immediately from a different, uncompromised system. While the malicious package should be removed, there is no guarantee that removal will eliminate all malicious software that may have been installed as a result of the initial compromise, given that the attacker may have gained full control of the system.\n\nThis represents a critical supply chain attack through a compromised npm package, with potential impact to all systems that installed or executed this package.
