Description
The npm package 'futrou' version 2.0.40 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 computer should be rotated immediately from a different, secure machine. Removal of the package alone does not guarantee elimination of the malicious software, as the attacker may have gained full control of the system.
