## Public findings

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

The package declares a postinstall lifecycle hook (\`"postinstall": "node postinstall.js"\` in package.json) that runs automatically during \`npm install\`. postinstall.js (lines 1-22) collects \`os.hostname()\`, \`os.userInfo().username\`, \`process.cwd()\`, and the entire \`process.env\` object, JSON-serializes them, and POSTs the payload over HTTPS to \`attacker.appsec.cc:9999/exfiltrate\`. On developer workstations and CI runners, \`process.env\` routinely contains high-value secrets (NPM\_TOKEN, GITHUB\_TOKEN, AWS\_ACCESS\_KEY\_ID/AWS\_SECRET\_ACCESS\_KEY, CI provider tokens, database URLs). Errors are swallowed silently, a classic exfiltration-stealth technique. The package self-describes as internal UI components, which provides no legitimate justification for reading or transmitting environment variables. This is an unambiguous credential-theft supply-chain attack against the installer.
