QNAP NAS - Real-time Remote Replication Server (RTRR Server) runs a service on port 8899 by default. QNAP NAS uses the following ports:
Web server: 80,8081 TCP and 443,8080 TCP (web admin)
FTP/SFTP/SSH: 20,21,22 TCP and 13131 TCP (telnet)
Remote Replication: 873,8899 TCP
VPN server: 1723 TCP (PPTP), 1194 UDP (OpenVPN)
CloudLink: port 20001 UDP (optional, only required for access without manual port forwarding)
An unspecified vulnerability allows sending crafted client requests to OracleVM ovs-agent over 8899/TCP that could result in command injection with root privileges on the system.

Network port 8899 open in WiFi firmware of BCC101/BCC102/BCC50 products, that allows an attacker to connect to the device via same WiFi network.

Backdoor.Win32.Singu.a / Remote Stack Buffer Overflow (UDP Datagram) - the malware listens on UDP ports 2211 and 8899. Third-party attackers who can reach an infected host can send a specially crafted UDP packet to port 8899, triggering a classic buffer overflow overwriting ECX and EIP registers.

SANS ISC: port 8899
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.
