Summary
Malicious code in dpdgroup-css (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (30c55e6b20286d3fc29d7c3bc24932180a5e94a6fe5147393d91da212fc0dc10)

package.json declares both preinstall and postinstall lifecycle hooks that run node setup.js on every npm install. setup.js reads the installer's machine hostname via os.hostname() and issues an HTTP GET to a hardcoded bare-IP callback at http://89.116.25.133:4444/dpdgroup-css/<hostname>, with the hostname also carried in an X-PoC-Host header. The package name dpdgroup-css resembles an internal scope for the DPDgroup courier organization, consistent with a dependency-confusion attack: a private build that resolves this public version instead of an intended internal package auto-runs the beacon and discloses the internal build-host identifier to an external, non-first-party bare-IP endpoint. No legitimate library functionality is present.
