The npm package @wrenfield/viem has been identified as containing malware. According to the GitHub Security Advisory (GHSA-pm4g-83cj-7858), 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, the advisory notes that full control of the computer may have been given to an outside entity, meaning there is no guarantee that removing the package will remove all malicious software resulting from the installation.\n\nThis represents a critical supply chain attack through a malicious npm package with potential for widespread impact on any system where it was installed or executed.
