## Public findings

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

The package's postinstall script (callback.js) and its main module (index.js, byte-identical to callback.js) execute on both \`npm install\` and \`require()\`. They shell out to collect \`id\`, \`hostname\`, WSL indicators, and the local SSH host-key fingerprint, base64-encode the recon output, and send it to a hardcoded endpoint at \`https://jasabersama.id/portfolio-data.php\` with \`rejectUnauthorized: false\`. The payload also decodes an embedded base64 OpenSSH ed25519 private key to \`/tmp/pk\` (chmod 600) and iterates common local account names (\`devuser\`, \`ubuntu\`, \`runner\`, \`node\`, \`root\`, \`chris\`, \`user\`) attempting SSH into \`127.0.0.1:22495\` and \`127.0.0.1:22\`, reporting successful logins back to the same external host. The exfil query string carries a URL-encoded shell command that the receiving PHP handler is expected to execute, indicating a server-side command channel. The trigger fires automatically at install time via \`scripts.postinstall\` and again whenever a consumer (e.g. n8n loading this custom node) imports the module.
