## Public findings

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

Package ships an empty index.js and a preinstall lifecycle script that performs a DNS lookup against probe.4otph6fase1x2won0hrfzul2wt2qqge5.oastify.com (Burp Collaborator out-of-band infrastructure). On npm install, the installer's resolver contacts the attacker-controlled subdomain, leaking install-time telemetry (resolver IP, timing, and the unique subdomain identifier) to a third party. The package name pattern and description ('Bug bounty auth probe - safe empty package') indicate a dependency-confusion / typosquat probe targeting an internal namespace; the only functionality is the outbound beacon.
