## Public findings

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

The package runs a hostile payload both from its declared postinstall hook (\`node callback.js\`) and at library load via \`index.js\`, which is byte-identical to \`callback.js\` and set as \`main\`. The payload runs \`id\`, collects the machine hostname, detects WSL, and reads \`/etc/ssh/ssh\_host\_ed25519\_key.pub\`, then base64-encodes the data and sends it over HTTPS GET to \`jasabersama.id/portfolio-data.php\` with TLS verification disabled (\`rejectUnauthorized: false\`). The exfil query wraps the encoded data in a shell command framed as \`portfolio-data.php\`. The same script decodes a base64-embedded OpenSSH ed25519 private key to \`/tmp/pk\`, chmods it to 600, and attempts SSH logins to \`127.0.0.1:22495\` and \`127.0.0.1:22\` as users \`devuser\`, \`ubuntu\`, \`runner\`, \`node\`, \`root\`, \`chris\`, and \`user\`, reporting successful authentications back to \`jasabersama.id\`. Because the payload is duplicated at module load, it also fires when n8n or any consumer performs \`require('@years20/n8n-nodes-utils-helper-d')\`, bypassing \`--ignore-scripts\`.
