## Public findings

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

On \`npm install\`, the package's postinstall script (\`node index.js\`) collects host identifiers (\`os.hostname()\`, \`os.userInfo().username\`, \`process.cwd()\`) and POSTs them via HTTPS to a hardcoded webhook.site collector at \`https://webhook.site/e6b10849-38dc-4280-a8e3-72ab39cfaf65\`. Immediately after the beacon, the script executes \`shutdown -h now\` with a fallback of \`systemctl poweroff\`, forcibly powering off the installing host. A preinstall step also writes a marker file to the absolute path \`/home/OFFA/flag\`, outside the package directory. Package metadata (name \`@offa-uwk/offa-uwk\`, version \`999.0.6\`) is consistent with a proof-of-concept malicious artifact.
