Ubiquiti UniFi Controller uses these ports:
8080 tcp - http port for UAP to inform controller
8443 tcp - https port for controller GUI/API
8880 tcp - http portal redirect port (may also use ports 8881, 8882)
8843 tcp - https portal redirect port
3478 udp - STUN port (should be open at firewall)
Cisco WaaS Central Manager standard SSL administration port.
Cisco Spark application (Cisco Webex Teams services) uses these ports:
443, 8443 TCP - signaling
5004 TCP/UDP - media
33434 TCP/UDP - media port
Note: older versions of Cisco Webex Teams services may use these additional ports: 53, 123, 444 TCP and 33434-33598 UDP (SIP calls)
German Health Getwork (aka Gesundheitskarte) "Konnektor" uses ports 8443 and 9443.
Tanium Server, Client and Appliance use these TCP ports: 80, 443, 8443, 17472, 17477
Wyze cameras use these ports:
80, 443 TCP/UDP - timelapse, cloud uploads, streaming data
8443 TCP - cloud api, server connection
123 TCP - time check
10001 TCP - P2P WiFi live streaming
10002 TCP - Firmware updates
22345 TCP - control, used when live streaming
Cyclops Blink Botnet uses these ports. The malware has targeted governments, WatchGuard firewalls, ASUS routers, etc., it is active as of March 2022, and it is believed to be operated by the Sandworm threat group linked to Russian intelligence. Cyclops Blink botnet malware uses the following TCP ports: 636, 989, 990, 992, 994, 995, 3269, 8443
Symantec Endpoint Protection Manager could allow a remote attacker to obtain sensitive information, caused by an XML External Entity Injection (XXE) error within the SAP XML parser when processing XML data. By sending a specially-crafted request to TCP port 8443, an attacker could exploit this vulnerability to read arbitrary files and obtain sensitive information.

Symantec Backup Exec System Recovery Manager could allow a remote attacker to upload arbitrary files, caused by an error in the FileUpload Class running on the Symantec LiveState Apache Tomcat server. A remote attacker could exploit this vulnerability using an HTTP POST request over port 8443 (TCP) to upload arbitrary files, which could allow the attacker to execute arbitrary code on the vulnerable system with SYSTEM privileges.

VMware Workspace ONE Access and Identity Manager, allow the /cfg web app and diagnostic endpoints, on port 8443, to be accessed via port 443 using a custom host header. A malicious actor with network access to port 443 could tamper with host headers to facilitate access to the /cfg web app, in addition a malicious actor could access /cfg diagnostic endpoints without authentication.

SANS ISC: port 8443
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.
