The npm package 'sleek-pretty' version 1.0.0 contains malicious code that compromises any computer on which it is installed or running. This compromise allows an attacker full control over the affected system, potentially exposing all stored secrets and keys. Immediate removal of the package is advised, but due to the extent of the compromise, removing the package alone may not eliminate all malicious software. Secrets and keys should be rotated from a different, uncompromised machine.
