.._one_ way of using this knowledge, is keep a few sacrifical Wintendos
in a "lan" tarpit, and pose as "one of them", e.g. "about to fall over"
to try get the bad guys to try save their catch, and buy you time to
evade them.

..the best way is have people look for weird behavior, you don't
need to know how to read kernel source or what to look for, to
recognise new "weird shit it didn't do before yesterday", even
WWI security skills will work fine here, and that means, say,
7 billion eyes watching.
