MAL-2026-10616 Malicious code in smb-portal-uikit (npm)

Package [email protected] declares a preinstall lifecycle hook that runs node index.js. On npm install, index.js invokes child_process.exec on whoami and id, reads os.hostname(), os.userInfo(), process.platform, and process.cwd(), and POSTs the collected host reconnaissance to a hardcoded attacker-controlled endpoint at https://a2dmzqok5w5seb3fac3w4kvcz35utohd.oastify.com (an oastify.com subdomain, a Burp Collaborator out-of-band interaction host commonly used as an exfiltration/beacon sink). The package ships no legitimate UI-toolkit functionality consistent with its name; the entire install-time behavior is reconnaissance and exfiltration.
