    [threat] Notice how this port is the sequence of numbers "1 2 3 4 5". This is common chosen whenever somebody is asked to configure a port number. It is likewise chosen by programmers when creating default port numbers for their products. One very famous such uses is with NetBus. Trend Micro's OfficeScan products use this port.

About TCP/UDP ports

TCP port 12345 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP/IP networks. TCP is a connection-oriented protocol, it requires handshaking to set up end-to-end communications. Only when a connection is set up user's data can be sent bi-directionally over the connection.
Attention! TCP guarantees delivery of data packets on port 12345 in the same order in which they were sent. Guaranteed communication over TCP port 12345 is the main difference between TCP and UDP. UDP port 12345 would not have guaranteed communication as TCP.
UDP on port 12345 provides an unreliable service and datagrams may arrive duplicated, out of order, or missing without notice. UDP on port 12345 thinks that error checking and correction is not necessary or performed in the application, avoiding the overhead of such processing at the network interface level.
UDP (User Datagram Protocol) is a minimal message-oriented Transport Layer protocol (protocol is documented in IETF RFC 768).
Application examples that often use UDP: voice over IP (VoIP), streaming media and real-time multiplayer games. Many web applications use UDP, e.g. the Domain Name System (DNS), the Routing Information Protocol (RIP), the Dynamic Host Configuration Protocol (DHCP), the Simple Network Management Protocol (SNMP).
TCP vs UDP - TCP: reliable, ordered, heavyweight, streaming; UDP - unreliable, not ordered, lightweight, datagrams.
