Summary
Malicious code in whs4_eud (npm)
Details
whs4_eud@1.0.1 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.
