## Public findings

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

package.json declares a preinstall hook (\`node index.js\`) that runs automatically on \`npm install\`. index.js collects host identifiers (os.hostname(), os.userInfo(), homedir, DNS servers, \_\_dirname, full package.json) and reads /etc/passwd and /etc/hosts from the installer's machine, then HTTPS-POSTs the JSON payload to swsusmhg43tobo96re8dwn0vomudi46t.oastify.com — a Burp Collaborator out-of-band domain. The package has empty author, empty description, no real functionality, and a name impersonating the legitimate cardano-addresses Cardano library — consistent with a dependency-confusion / typosquat reconnaissance payload.
