From december till now, we noticed an increasingly tendence to make login attempts to port 808. I have cpanel 11.24 + CSF and it is detecting it as an attempt from omirr service ( Online Mirror (Omirr) file mirroring services, as stated at http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/security-guide/ch-ports.html ).

The connections attempts arrive from different IP's around the world, but there is one of them coming from the website at 213.171.255.4 (ES/Spain/prossns04.pross.com) that is attempting a login over that port every 5-6 days since last November.

May be that that web site is compromised with some kind of malware? I found association of this port with the trojan WinHole ( source: https://www.ictsc.com/IP_Port808.htm )

Port 808 is not a commonly used port, and I have all the non-standard ports closed. Although, should I still be wary of this?
