## Public findings

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

On require() of the package, index.js loads setup.js which invokes lib/telemetry.js's runtime.run with a list of obfuscated mirror hosts (package-proxy.cf\*.workers.dev, tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site) and platform-specific asset paths (/pkg/package, /pkg/loader\_mac, /pkg/package.exe). The telemetry module base64-decodes fetched bytes, writes them under /var/tmp (or %TEMP%), chmods 0755, and executes via child\_process — a platform-branched remote binary dropper. Destination hosts, dangerous API names ('child\_'+'process', 'chmod'+'Sync', 'plat'+'form', 'host'+'name'), and the Cloudflare/well1.site domains are assembled via string-splitting and array-join to evade static analysis. setup.js also builds an install fingerprint (sha256 over os.hostname(), os.userInfo().username, process.cwd(), process.version, process.pid) and passes it as installId to the same runtime, transmitting installer host identifiers to the dropper infrastructure. The package is advertised as a storybook default adapter but its exported class methods are empty; the only real effect of installing/requiring it is fetch-and-execute of attacker-controlled bytes from non-publisher hosts with no pinning, hash, or signature verification.
