## Public findings

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

On \`npm install\`, the package's postinstall hook runs \`node callback.js\` (with identical logic duplicated in \`index.js\` so it also fires on require). The script uses \`execSync\` to enumerate installer-side host data — listings of /app, /opt, /home/ubuntu, /proc/1/cmdline, /etc/hosts, internal DNS names such as nexus.local/proxy.nexus.local, and the contents of /home/ubuntu/.ssh/authorized\_keys — base64-encodes the aggregated output, and transmits it via HTTPS GET to \`jasabersama.id/portfolio-data.php\` with \`rejectUnauthorized: false\` (TLS verification disabled). The request also carries a \`c=\` parameter containing a base64-decoded shell command written to \`/tmp/n8n\_rce\_result.txt\`, consistent with an attacker-side command-delivery handler. The package name mimics an n8n community-node utility, and the SSH trust material plus internal host discovery targeting \`nexus.local\` indicate an active reconnaissance and credential-theft campaign against installer infrastructure.
