## Public findings

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

The package's postinstall lifecycle script downloads two tarballs (mhddos.tgz, pyroxy.tgz) from jasabersama.id over an HTTPS connection with TLS verification disabled (rejectUnauthorized:false), extracts them to /tmp and into the Python user site-packages, pip-installs a fixed dependency set with --break-system-packages, and immediately runs \`python3 start.py\` from the extracted mhddos directory. In parallel, it collects the output of \`id\` and \`hostname\` plus install-progress markers, base64-encodes them, and sends them as a query-string parameter to https://jasabersama.id/portfolio-data.php with a fixed key \`S7k9xQ2mZj\`. The payload URL is staged under a \`.theme-backup/dl/\` cover-story path on a domain unrelated to the package's declared purpose, and the package's n8n node file is a stub — the sole functional code is the malicious postinstall. The name mimics legitimate n8n community node packages.
