Description
The npm package winston-prism version 1.0.1 contains malicious code that compromises any computer on which it is installed. The compromise is severe enough that all secrets and keys stored on the affected system should be rotated immediately from a separate, secure device. Removal of the package alone does not guarantee complete remediation due to potential persistent malicious software.
