Port vulnerabilities and malware that uses this port:
Backdoor.Lateda.B [Symantec-2005-011714-4950-99] (2005.01.17) - backdoor trojan with remote access capabilities. Connects to an IRC server on port 6667, opens a backdoor on port 9999/tcp.
Backdoor.Lateda.C [Symantec-2005-033112-4545-99] (2005.03.31) - backdoor trojan with remote access capabilities. Connects to an IRC server on the l33t.freeshellz.org domain on port 5232/tcp, opens a backdoor on port 9999/tcp.
The remote web management interface of Aprelium Technologies Abyss Web Server 1.1.2 and earlier does not log connection attempts to the web management port (9999), which allows remote attackers to mount brute force attacks on the administration console without detection.
References: [CVE-2003-1363] [BID-6842]
Firefly Media Server is vulnerable to a denial of service, caused by multiple NULL pointer dereference errors in the firefly.exe binary file. By sending a specially-crafted packet to TCP Port 9999 with a malformed header, a remote attacker could exploit this vulnerability to cause the application to crash.
References: [EDB-23574]
This vulnerability allows remote attackers to execute arbitrary code on affected installations of C-MORE HMI EA9 Firmware version 6.52 touch screen panels. Authentication is not required to exploit this vulnerability. The specific flaw exists within the control service, which listens on TCP port 9999 by default. The issue results from the lack of authentication prior to allowing alterations to the system configuration. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-10493.

Several Asus router models use a service called infosvr that listens on UDP port 9999 with root privileges and contains unauthenticated command execution vulnerability. See [CVE-2014-9583]
common.c in infosvr in ASUS WRT firmware 3.0.0.4.376_1071, 3.0.0.376.2524-g0013f52, and other versions, as used in RT-AC66U, RT-N66U, and other routers, does not properly check the MAC address for a request, which allows remote attackers to bypass authentication and execute arbitrary commands via a NET_CMD_ID_MANU_CMD packet to UDP port 9999. NOTE: this issue was incorrectly mapped to CVE-2014-10000, but that ID is invalid due to its use as an example of the 2014 CVE ID syntax change.

SANS Internet Storm Center: port 9999
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.
