Description
The 'that-fetch' 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 computer should be rotated immediately from a different machine. Removing the package alone does not guarantee removal of all malicious software, as full control may have been given to an external attacker.
