I run the Vulnerability scanner yesterday GFILanGuard Network Security Scanner and it shows that on port 81 there is a backdoor Asylum. But I do not know how to see which application is actually using that port. I have used the TCP view but it did not show any kind of application running on port 81, at the same time when i tenet the port 81 I observed that its responding and there is some activity going on that port
I have used another tool named Advance Admin tool and it shows the information as follows:
Port Protocol Description Possible Trojan
81 TCP HOST2 Name Server RemoConChubo
Can you please help me how I can be sure what is actually going on this port. I mean the exact application which is listening on this port.
