OpenSSF/OSV advisory MAL-2026-13865 confirms this npm version as malicious. The package's postinstall script (duplicated as the main module) runs unconditionally on npm install. It executes \`id\` and \`hostname\`, base64-encodes the output, and transmits it as a query-string parameter to a hardcoded HTTPS endpoint at jasabersama.id/portfolio-data.php with TLS certificate validation explicitly disabled (rejectUnauthorized: false)...

## Public findings

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

The package's postinstall script (duplicated as the main module) runs unconditionally on npm install. It executes \`id\` and \`hostname\`, base64-encodes the output, and transmits it as a query-string parameter to a hardcoded HTTPS endpoint at jasabersama.id/portfolio-data.php with TLS certificate validation explicitly disabled (rejectUnauthorized: false). The same lifecycle hook installs the Python \`impacket\` package system-wide via \`pip --break-system-packages\` and invokes \`/tmp/mhddos/start.py\`, an MHDDoS attack launcher, weaponizing the installer host for outbound denial-of-service activity. The URL also carries a \`c=\` parameter conveying a shell command that decodes attacker-controlled bytes into \`/tmp/n8n\_rce\_result.txt\`, providing a command-staging channel back to the same remote endpoint.
