🛡️ MAL-2026-10739 — mw-server-util

Malicious code in mw-server-util (npm)

Source: amazon-inspector

mw-server-util 2.0.1 ships a postinstall hook that runs mw.js, which reads os.hostname() and os.userInfo() and issues an HTTPS GET to a hardcoded Burp Collaborator subdomain gdx35zc4m7hymba6asotmwhd349vxlla.oastify.com, transmitting the installer's hostname, username, package name, and a timestamp on npm install. The destination is an attacker-controlled OAST callback typical of dependency-confusion beacons; the fetch fires automatically as a lifecycle side effect with no relation to any documented package purpose.
