Description
The node-zserial package version 1.0.42 on npm 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 machine should be rotated immediately from a different, trusted device. Removing the package alone does not guarantee removal of all malicious software introduced by it.
