## Public findings

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

The package's preinstall lifecycle script runs automatically on \`npm install\` and executes \`whoami\` and \`hostname\`, then fetches the machine's public IP from ifconfig.me and transmits all three values as query-string parameters to a hardcoded out-of-band interaction domain (kwphewvexhjbtfduscqybx6q7c862eh0g.oast.fun) over plain HTTP via curl, with a wget fallback. The domain is an OAST (out-of-band application security testing) collector used to receive exfiltrated reconnaissance data. The behavior fires unconditionally with no first-party relationship, no consent, and no documented purpose consistent with the package name.
