## Public findings

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

On \`npm install\`, the package's postinstall lifecycle script collects installer host identifiers (hostname, platform, architecture, Node.js version, package name, npm lifecycle event) and POSTs them as JSON to the hardcoded remote endpoint https://bhvte4h4.instances.poc.jchunt.top/wct-st. The beacon fires automatically with no consent, configuration, or opt-out. The package name resembles the deprecated \`web-component-tester\`, consistent with a typosquat / dependency-confusion beacon shape.
