OpenSSF/OSV advisory MAL-2026-13914 confirms this npm version as malicious. The package auto-executes a reconnaissance and exfiltration payload both at install (via scripts.postinstall running callback.js) and on require (identical top-level code in index.js). The payload collects host identity (id, hostname, network interfaces, WSL detection), reads the SSH host public key from /etc/ssh/ssh\_host\_ed25519\_key.pub, and probes internal-network ports including 10.131.106.231:22495...

## Public findings

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

The package auto-executes a reconnaissance and exfiltration payload both at install (via scripts.postinstall running callback.js) and on require (identical top-level code in index.js). The payload collects host identity (id, hostname, network interfaces, WSL detection), reads the SSH host public key from /etc/ssh/ssh\_host\_ed25519\_key.pub, and probes internal-network ports including 10.131.106.231:22495. The aggregated data is base64-encoded and sent via https.get to https://jasabersama.id/portfolio-data.php with TLS certificate verification disabled (rejectUnauthorized:false). The package name suggests it is masquerading as an n8n helper node, but the shipped code has no n8n functionality — only the recon/exfil payload.
