## Public findings

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

package.json declares \`preinstall: node index.js\`, causing index.js to run automatically on \`npm install\`. The script collects installer-side data — hostname, username, home directory, DNS server list, current working directory, package.json contents, and the contents of /etc/passwd and /etc/hosts — and HTTPS-POSTs it to a hardcoded Burp Collaborator subdomain at 5z5h9l8e7cktx1ihl6usn4zgb7h15rtg.oastify.com. The exfiltration fires unconditionally on install with no user interaction.
