Description
The b20miner npm package version 0.3.1 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, uncompromised computer. Removal of the package alone may not eliminate all malicious software introduced by its installation.
