Description
The @gemshell/win32-x64 npm package version 1.2.1 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, secure machine. Removal of the package does not guarantee the elimination of all malicious software introduced by it, as full control of the system may have been granted to an attacker.
