Description
The j4pe0w 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 machine should be rotated immediately from a different device. Removing the package alone does not guarantee removal of all resulting malicious software or control established by the attacker.
