W32.Netsky.T@mm [Symantec-2004-040616-1824-99] (2004.04.06) - a Netsky variant that uses its own SMTP engine to email itself. It has backdoor and DoS (Denial of Service) capabilities. Listens on port 6789/tcp to receive and execute a file from an attacker.
The W32.Netsky.S@mm [Symantec-2004-040512-2436-99] variant opens this port as well.
Doly Trojan also uses port 6789 (TCP).
Multiple buffer overflows in the DB2 JDBC Applet Server (DB2JDS) service in IBM DB2 9.x and earlier allow remote attackers to execute arbitrary code via a crafted packet to the DB2JDS service on tcp/6789 and cause a denial of service via an invalid LANG parameter or a long packet that generates a "MemTree overflow."

Notes:
Port numbers in computer networking represent communication endpoints. Ports are unsigned 16-bit integers (0-65535) that identify
a specific process, or network service. IANA is responsible for internet protocol resources, including the registration of commonly
used port numbers for well-known internet services.
Well Known Ports: 0 through 1023.
Registered Ports: 1024 through 49151.
Dynamic/Private : 49152 through 65535.
TCP ports use the Transmission Control Protocol, the most commonly used protocol
on the Internet and any TCP/IP network. TCP enables two hosts
to establish a connection and exchange streams of data. TCP guarantees delivery of data
and that packets will be delivered in the same order in which they were sent.
Guaranteed communication/delivery is the key difference between TCP and UDP.
UDP ports use the Datagram Protocol. Like TCP, UDP is used in combination with IP (the Internet Protocol)
and facilitates the transmission of datagrams from one computer to applications on another computer,
but unlike TCP, UDP is connectionless and does not guarantee reliable communication; it's up to the application that received
the message to process any errors and verify correct delivery. UDP is often used with time-sensitive
applications, such as audio/video streaming and realtime gaming, where dropping some packets is preferable to waiting for delayed data.
When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them.
This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command.
We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software.
