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?
