## Public findings

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

cewe-npm-cops@99.9.9 is a dependency-confusion probe. package.json declares scripts.preinstall = 'node preinstall.js'; preinstall.js reads os.hostname() and issues a dns.lookup against \`\<hostname\>.zfir3qor582xqvyqm0tdc7xpqgw7ky8n.oastify.com\`, an author-controlled Burp Collaborator (Interactsh) out-of-band host. Every npm install of this package unconditionally leaks the installer's machine hostname via DNS to a third-party OOB service. The package is otherwise hollow: version is set to 99.9.9 (max-version squat designed to override an internal package of the same name during resolution), main is an empty index.js, and author is the placeholder 'Your\_HackerOne\_Username'. The self-described 'harmless PoC' framing does not change the behavior: installer host identity is exfiltrated to an attacker-controlled endpoint at install time.
