They infiltrated the Vatican
Tech is like a new religion to many.
And if many nations tell the Antivirus companies don't find our hacker shit, then you can get an idea of if they would stack the decks elsewhere. and i would not cost that much as they would earn $ from their job.
It wasn't long ago that 2IC in Linux Kernel team was spitting chips about all the interference. I always thought the spooks would be lurking there, building in the next hole, in case some nation tries to develop an independent operating system.
Problems arise when Tech is over commercialised and people are complacent, not just spooks.
but "sleepers', those that are totally unaware to the effect of what they do and those that just don't care.
