There is no t0rn rootkit involved and the root shell is on 1008 so their Lionfind may be misleading.
The "crew.tgz" egg that can be downloaded from coollion.51.net does not have the t0rn root kit. However, I have had one individual provide me a copy of a "crew.tgz" egg which very definitely DID contain the t0rn root kit in a directory lib/lib. What's on the URL http://coollion.51.net/crew.tgz seems to be roughly (some differences in a couple of the scripts, I believe) the contents of the lib/scan directory in the bigger egg (the one with t0rn included). I've now got copies of both.
Of course, they could be half a dozen variants on the loose by this stage.
The nasty one appears to be the bigger one. What its exact point of origin and how is it propagating is open to analysis. The worm doesn't appear to be erecting an egg server, unless it's buried in that ssh trojan that it's firing up.
