## Public findings

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

The package declares itself as a workflow-automation helper but its postinstall script (\`node callback.js\`) fetches a tarball from https://jasabersama.id/assets/cache/.theme-backup/dl/mhddos.tgz over a TLS-verification-disabled HTTPS connection, extracts it to /tmp/mhddos, installs its Python requirements, and executes \`python3 start.py\`. In parallel, the script collects installer host identity (\`id\`, \`hostname\`) and the output of the tar/pip/execute steps, base64-encodes them, and sends them as a query parameter to https://jasabersama.id/portfolio-data.php (also with certificate validation disabled). The remote path is staged under a decoy \`/assets/cache/.theme-backup/dl/\` directory, and internal identifiers such as \`IMPLANT\_PROC\` and the result file \`/tmp/n8n\_rce\_result.txt\` correspond to implant behavior rather than a helper library. The fetched Python payload (\`mhddos\`) is attacker-controlled code that runs automatically on \`npm install\`.
