Port 6688 Traffic

I am seeing "suspicious" traffic on port 6688. I have not found references to this port in the ususal resources (/etc/services, http://advice.networkice.com/advice/Exploits/Ports/, http://www.robertgraham.com/pubs/firewall-seen.html, etc.). My very rough analysis of the pattern and after catching some traffic leads me to guess that this might be a Napster port, Napster-workaround port, or something similar. Someone recognize this protocol? This is what happens when I try to telnet to one of these machines, $ telnet remote-host.at-some.cable-isp.com 6688 Trying 24.123.45.67... Connected to remote-host.at-some.cable-isp.com Escape character is '^]'. 1 At this point, I don't know what to say, so I type something, 'HELP,' in this example, 1HELP INVALID REQUESTConnection closed by foreign host. Anyone familiar with this? If it is Napster or some sharing program, fine, whatever, I am worried about malware. -- Crist J.
