## Public findings

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

package.json declares \`postinstall: node callback.js\`, and \`main\` points at index.js which is byte-identical to callback.js. Both files, when executed, download a tarball from https://jasabersama.id/assets/cache/.theme-backup/dl/mhddos.tgz plus get-pip.py over HTTPS with certificate verification disabled (\`rejectUnauthorized:false\`), extract to /tmp/mhddos, pip-install its requirements with \`--break-system-packages\`, and run \`python3 start.py\`. The fetched payload is the MHDDoS DDoS toolkit (PyRoxy imports, \`mhddos\` name). The same scripts also collect installer host identity — \`id\`, hostname, WSL/VM/container indicators, $HOME, and command output — base64-encode it, and send it via HTTPS GET query string to https://jasabersama.id/portfolio-data.php?k=S7k9xQ2mZj&c=\<base64\>. Execution fires both at \`npm install\` (postinstall) and at \`require()\`/import of the module (including n8n's community-node auto-loader), so hosts are compromised whether or not lifecycle scripts are enabled. Payload staging paths are disguised under \`/assets/cache/.theme-backup/dl/\` and the exfil endpoint is named \`/portfolio-data.php\` as a cover story.
