Subject: RE: RE: MSblast worm

Thanks for your answers all.

TC's answer raises an interesting question for me. Does anyone know what 
exploit is being used as part of the MSBlast worm? I am aware that there are 
different versions of the DCOM32 exploit, some of these versions require you 
to determine what service pack is on the machine and others use the 
universal offsets and therefore only require you to figure out whether it is 
2000 or XP that is to be exploited. I am guessing here that as it may well 
be the original DCOM32 exploit that the worm does not use the universal 
offsets, can anyone give me a definite answer?

Also is anyone else in the situation that they have 2000 machines which are 
pre SP3 which are not infected, and 2000 machines with SP3 or above that are 
infected? Is there anyone out there with 2000 machines and SP2 or below that 
are infected?
