Description
The @ms-ows/logging npm package contains malicious code that compromises any computer on which it is installed or running. The compromise is severe enough that all secrets and keys stored on the affected system should be rotated immediately from a different, trusted machine. Simply removing the package does not guarantee removal of all malicious software or backdoors introduced by the package.
