Background
nodetokyo is an npm package designed to provide a 'Stealth Assistant' functionality. It is intended to assist users in various tasks while remaining unobtrusive. However, this package has been found to contain malicious code that compromises user privacy by capturing sensitive information from the clipboard and screen.
