The npm package dl-pp-latm version 80.4.2 contains malicious code that executes automatically during installation. It runs preinstall and postinstall scripts that collect sensitive machine information such as hostnames, usernames, home directories, DNS servers, current working directory, and the full package.json file. This data is then transmitted to a third-party external server via HTTPS POST and DNS lookup. The package appears to be part of a dependency-confusion attack targeting internal or private package names, causing leakage of internal hostnames, usernames, and DNS configurations from developer workstations or CI systems without user interaction.
