[Dshield] New Variant of Linkbot

It's a hardly-ever used registered port.

It's registered to: Cliff Neuman's Prospero Directory Service

I'm sure it's not related but here's the scoop on Prospero:
   Cliff Neuman described Prospero. It follows a file system model, rather
   than the hypertext model. It is built on UDP for speed. It has the
   notion of a Directory which contains links to other objects (other
   directories or files). It returns the link to the information object and
   then automatically retrieves the file by another mechanism by the
   appropriate access method (Archie, WAIS, nntp, WWW - soon!, NFS, ftp
   etc.) It has been used very successfully to access the archie database.
   Cliff stated that he expected to be able to use X.500 to translate
   between the document ID and how to get the document.

   With Prospero the user has his own view of the global information base
   (or has a view built for him). Cliff thought there should be multiple
   name spaces - but the difficulty would be that these would need
   representing near the top of the directory tree. With multiple user
   chosen views - this would be difficult to manage. Also two users might
   refer to an object by different handles which would be relative to their
   individual name spaces - difficult when passing references (say in a
   mail message) from one person to the other.

More on the virus.  I'll get a compressed, protected version as soon as I
can.  I've done more evaluation on our Firewall and it seems that this may
have been a timebomb - I have records of several machines starting to talk
to at appx. the same time.  Maybe we've had the virus
banging around for some time.
