Port 8881 is commonly associated with Atlasz Informatics Research Ltd.'s Secure Application Server, a platform intended to facilitate secure application deployment and communications, primarily over TCP. While its utilization isn't standardized or well documented, it often serves proprietary secure communication processes or remote management interfaces that demand careful access control and monitoring due to elevated security implications.

Which one is on your host

ask the machine, not the registry

The registry says what 8881 is registered to. What is listening on it right now is decided by the host, and only the host can be asked. Each of these prints the process behind the socket.

linux
ss -ltnp | grep ':8881\b'
macos
lsof -nP -iTCP:8881 -sTCP:LISTEN
windows
netstat -ano | findstr :8881

On Linux and Windows the process name comes back with the socket; on macOS lsof needs sudo to name a process that isn't yours. Match what it prints against the 2 entries above.

A port number is not a service. Anything may listen on 8881 — what you actually met is decided by the host, not the registry. If a service is missing here, it belongs in the registry.
