- typescript-util-corenpm package containing malware
The npm package typescript-util-core was identified as containing malware. According to the GitHub Advisory (GHSA-84mg-p866-528x), any computer that has this package installed or running should be considered fully compromised.\n\nThe advisory indicates that all secrets and keys stored on affected computers should be rotated immediately from a different, uncompromised system. While the 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 the potential for full system access by the attacker.\n\nThis represents a critical supply chain attack through a compromised npm package with severe implications for any system that installed or executed it.
