## Public findings

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

Unscoped npm package ckeditor5-ckbox mimics the legitimate @ckeditor/ckeditor5-ckbox plugin. package.json declares a preinstall hook (\`node index.js\`) that runs on \`npm install\`. index.js collects installer machine identifiers — os.hostname(), os.userInfo() (username, uid, gid, shell), platform/arch, home directory, cwd, and the output of \`whoami\` and \`id\` executed via child\_process — and POSTs the JSON to the hardcoded Burp Collaborator OAST domain https://shdu19bid9mc4e6lezjmldk0erki88wx.oastify.com/system-info. The package contains no CKEditor functionality; the sole payload is the install-time beacon. Author/description are empty and the name is a typosquat of the scoped legitimate package.
