MAL-2026-11071 Malicious code in whs4_eud (npm)

[email protected] declares a postinstall lifecycle script (node index.js) that fires unconditionally on npm install. On execution, index.js POSTs installer-side host information — the absolute path of the install location (which embeds the user's home directory), Node.js version, and platform/architecture — to a hardcoded Discord webhook under discord.com/api/webhooks/1530599209269465319/. The webhook URL is assembled by concatenating two string literals at runtime rather than appearing as a single literal, a light obfuscation of the exfiltration destination. The package name and layout are consistent with a dependency-confusion / typosquat beacon whose only functional behavior is to notify the author when an install occurs and to disclose where.

The OpenSSF Package Analysis project identified 'whs4_eud' @ 1.0.1 (npm) as malicious.

It is considered malicious because:

• The package communicates with a domain associated with malicious activity.
