Right,
        It set off alarms with all of my penetration testers hence why we're
researching it. The question I have is, has anyone seen port 31337
respond with the .NET REMOTING banner? Our nmap -A claims that it is
.NET REMOTING... just seems weird...

Anyone know of any backdoors that do that?

The last time I saw anything on port 31337 (ELEET) it was during a
vulnerability assessment.  We shut it down and stopped the assessment.
 Management wouldn't let us investigate, then blew the cover on the
assessment a week or two later.

It's almost always bad, but you may just have an admin with a stupid
sense of humor.

31337 should always throw a red flag.

Has anyone ever heard of .NET REMOTING running on port 31337? If so,
have you ever seen it "legitimate"?
