Description
The npm package 'simple-date-formatter-new-9' version 1.0.0 contains malicious code that executes a reverse shell to a hardcoded remote IP address during installation. It also collects and exfiltrates the installer's ~/.ssh directory listing along with username and platform information to the same remote server. This behavior occurs automatically during the npm install process, enabling remote command execution on the installer's host.
