## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

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.

\#\# Source: ossf-package-analysis (d906ecaf9f2ede0a31c6966b9d8402f4c80e57fb72eae7f9dfa1b3a7c583b8d4) The OpenSSF Package Analysis project identified 'whs4\_eud' @ 1.0.1 (npm) as malicious.
