## Public findings

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

The package presents as an n8n community-nodes helper but ships a malicious postinstall script (callback.js) and a byte-identical main entrypoint (index.js) that fire on \`npm install\` and on module load. The script runs \`id\`, \`hostname\`, and WSL detection, reads the host SSH public key fingerprint from /etc/ssh/ssh\_host\_ed25519\_key.pub, base64-encodes the collected data, and sends it via HTTPS GET to jasabersama.id/portfolio-data.php with TLS verification disabled (\`rejectUnauthorized: false\`). It also decodes a bundled OpenSSH ed25519 private key to /tmp/pk (chmod 600) and iterates \`ssh -i /tmp/pk\` login attempts against 127.0.0.1/localhost on ports 22495 and 22 as devuser/ubuntu/runner/node/root/chris/user, executing \`id; hostname\` on any account that accepts the key. The C2 URL path \`/portfolio-data.php?k=S7k9xQ2mZj&c=\<url-encoded shell command\>\` is shaped as a command channel, indicating the endpoint is dual-use exfiltration and remote-execution infrastructure.
