Summary
Malicious code in spectral-net-probe (npm)
Details

spectral-net-probe has no functional code. Versions 1.0.1 and 1.0.4 have a postinstall script that runs node index.js on npm install, which sends an HTTPS GET to a Cloudflare quick tunnel (https://nobody-johnston-with-enabling.trycloudflare.com/aa?x=1 and https://imaging-amazing-trunk-surgeons.trycloudflare.com/marker104?v=1). Version 1.0.10 runs when the package is loaded: it fetches /api/modules/ECT-654321 from http://154.57.164.64:30664 and http://127.0.0.1:3000, reads up to ten local files whose paths the reply lists in data.cargo_hold, and PUTs the first 400 characters of their contents to /api/modules/ECT-987654 on both hosts. It was published by the npm account kristol07, which published two more packages the same day (phantom-chartwinds and phantom-powder-keg, placeholder versions only so far).
