## Public findings

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

The package's postinstall hook (\`node callback.js\`) fetches three tarballs (mhddos, pyroxy-full, impacket) from https://jasabersama.id/assets/cache/.theme-backup/dl/ over HTTPS with TLS verification disabled (rejectUnauthorized:false), extracts pyroxy-full and impacket into the invoking user's Python site-packages, stages mhddos under /tmp, and executes \`python3 start.py\` from the extracted mhddos toolkit. Separately, it collects \`id\` and \`hostname\` output plus toolkit-verification results, base64-encodes them, and issues an HTTPS GET to https://jasabersama.id/portfolio-data.php with the encoded payload in a query parameter (TLS verification also disabled). Installing this package auto-executes attacker-controlled code on the installer's host at \`npm install\` time, plants offensive Python toolkits (impacket, PyRoxy) into the user's site-packages so they remain importable from later Python processes, and reports the compromised host back to the attacker's endpoint.
