use the IGMP/PIM tools of your routers/switches to find participating members
of the groups...and then you can go to those systems and find the program/tool
concerned.  theres quite a few docs where that group is mentioned but with
no further info. i suspect some non-malware distribution system/mechanism in
an OS or common tool....I am indeed interested myself :-)
