I don't see why MBrains can't engage in stealth and mobility as part of their defense. Also, I would presume were MBrains feasible and there were these kinds of deceptive, dispersed threats, there would likely to be repair mechanisms. One might, say, nuke part of an MBrain, but that might be the equivelent of taking out a few nodes of gigantic network. The only problem then would be preventing a catastrophic failure from either the sheer number or nodes or uberconnected nodes from being taken out. I'm sure, if they're feasible and likely, that this problem will be solved simply because "natural" disasters might have similar impact and thus the sort of defense and repair or immune system response will have to evolve in them.
