Description
The npm package 'ethesjs' version 1.0.0 contains malicious multi-stage information-stealing code that executes upon installation. It opens a new terminal during execution and compromises the host computer, potentially exposing all stored secrets and keys. Removal of the package does not guarantee elimination of all malicious components, as the attacker may have gained full control.
