How are these system getting compromised? Why don't you have this patch
deployed yet? Why are these systems reachable from the Internet over
port
445?

For someone who knows nothing about his network, you sure are willing
to make a lot of assumptions. You admit you don't know how the systems
were compromised and you don't know what compromised them, yet you
castigate him for leaving port 445 open and not patching and you
assume this happened *remotely*?



        [SNIP]

You're right, I made an assumption that the systems were being
compromised remotely rather than being deliberately and maliciously
hacked by insiders. Would this somehow be less of a problem? Having
systems with routable addresses reachable through port 445 is the most
likely avenue of compromise, if this is not the case then Josh would be
well advised to determine exactly what is going on with his network.


Agreed here, anyone sitting with exposed windows specific ports on the
insecure Internet <e.g. 445, 135-139, udp as well as tcp, etc> is pretty
much deserving of what hits them these days.  Without tackling that
side of the coin, it's going to be pretty hard for these folks to
determine if the troubles they are facing is internal or not.
Without control of the perimiter choke point, how can one even
think to start to look at controls of the whole danged wire inside?
Perhaps we need to adapt  personal firewall day to a monthly thing for
the next 5 years or more to help these clueless souls.

OK, so you're a Ph.D.  Just don't touch anything.
