Microsoft Malware Protection Center: We’ve had reports of a new worm in the wild and that generates increased RDP traffic for our users on port 3389.

We see hints like these regularly – malware authors proposing names for their malicious creations or suggesting a place where a signature based detection would be suitable. Of course, such hints are ignored by us for detection but make us smile for a short time. ...
