Hi again folks! I've had some mild success at poking inside the virus using
Sun's trace command on a Sun 3/50 running SunOS4.0. YP had to be shutdown
for this to be usefull and of course all routes were deleted so it couldn't
propagate anywhere outside the machine. This machine had a relatively small
/etc/hosts and /etc/passwd file so it did its thing pretty quickly. To
really see what it's doing the best scenario would be to run it on a network
with a very small number of other machines (and no gateways to other nets!)
to give it a chance to actually connect to something. What I did get was
interesting though it only tells only a partial story. Keeping up with it
was tricky since it would fork occasionally and exit, so I'd have to start
trace up and attach to that new process pretty quickly to see anything
happen. In this run it didn't look for individual .rhosts files (though it
looked at .forward files). My feeling is that it would look at .rhosts after
it's cracked the password for that person. It's not clear from this where
password cracking would happen either since a lot of that doesn't require
system calls. We have a disassembly of the thing as well and it's got a few
of its own routines to do password cracking (replacements for stuff allready
resident in UNIX). So here are some excerpts from trace with some redunancy
edited out and some comments embedded comments. Enjoy!!
