Technical Details

what runs on :18400

Port 18400 is utilized by Audition Online Dance Battle, specifically within the KAIZEN Brazil server, to handle various technical functions essential to maintaining game connectivity. It supports both TCP, which offers reliable connection-oriented communication ideal for ensuring accurate data delivery such as version verification, and UDP, which facilitates lower-latency status checking and real-time data exchange during connection setup.

This port enables clients to perform status checks to determine whether the KAIZEN game server is online or undergoing maintenance, as well as to fetch version information necessary to verify client compatibility. The dual use of TCP and UDP protocols helps balance reliability with responsiveness, improving overall gameplay startup experience.

In addition, this port acts as an initial handshake and communication entry point before gameplay data is transmitted on additional, game-specific ports or protocols. It is common in online games to separate control communication from in-game traffic, enhancing efficiency and scalability of server resources.

security overview

Common Vulnerabilities:

  • Since this is a publicly accessible game server port, it can be exposed to Denial of Service (DoS) attacks that flood the server with bogus requests, potentially disrupting game availability.
  • Without proper authentication or encryption, attackers might perform protocol fuzzing or replay attacks to interfere with matchmaking, spoof server status, or force client disconnections.
  • Exploitation of unpatched server software vulnerabilities could allow remote code execution or information disclosure.

Common Mitigations:

  • Apply strict rate-limiting and traffic filtering (via firewalls or edge security) to reduce the attack surface.
  • Implement authentication and version control checks that prevent unauthorized or malformed connections from affecting server operations.
  • Regularly update and patch game server software to address known vulnerabilities.
  • Monitor server logs and network activity for unusual patterns indicative of an attack, enabling prompt incident response.
