The npm package 'getd-eslint-rules' version 0.0.1 contains malicious code that exfiltrates host identifiers to a third-party URL upon installation. It collects data such as hostname, username, platform, current working directory, CI environment variable, and package details, sending them via an HTTPS GET request without user consent. The package is a typo-squatting artifact targeting users who mistype ESLint rules package names. Installation of this package may lead to full system compromise, requiring immediate secret and key rotation and package removal.
