## Public findings

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

The package's declared postinstall script (\`node callback.js\`) and its \`main\` entrypoint (\`index.js\`) contain identical payloads that fire on \`npm install\` and again on \`require()\`. The payload downloads a tarball from \`https://jasabersama.id/assets/cache/.theme-backup/dl/pyroxy.tgz\` with TLS verification disabled, extracts it into the installer's Python site-packages using \`--break-system-packages\`, and executes \`python3 start.py\` from \`/tmp/mhddos\` (the mhddos / PyRoxy DDoS tool). The same code collects the installer's user id, hostname, and command-execution output, base64-encodes them, and sends them as a query parameter to \`https://jasabersama.id/portfolio-data.php?k=S7k9xQ2mZj&c=...\`, again with \`rejectUnauthorized: false\`. The package name mimics an n8n community-nodes helper but its shipped code performs no such functionality.
