## Public findings

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

package.json declares scripts.preinstall = 'node index.js', so npm install auto-executes index.js. The script collects hostname, username, home directory, local IPv4, INIT\_CWD, and the public egress IP (queried from api.ipify.org, icanhazip.com, and ifconfig.me), and reads the consuming project's package.json (INIT\_CWD/package.json) to extract name, author, repository, and homepage — identifying which internal package name resolved to this public package. The payload is transmitted to the hardcoded collector da51rv0hb2uc72tg4gvgdepinjcallbk1.oast.fun via HTTPS POST to /poc/\<uuid\> and, in parallel, hex-encoded and chunked into DNS labels (\`\<idx\>-\<chunk\>.u-\<uuid\>.\<callback\>\`) resolved via dns.resolve, providing a fallback exfiltration channel when outbound HTTP is filtered. The package's self-description as a dependency-confusion research PoC does not change the behavior: installer host and parent-project identifiers are shipped to a third-party Interactsh collector without installer consent.
