I will answer questions.
IMB: Unfortunately detecting novel malware is very hard. I would suspect that a lot of the NSA malware doesn’t even live on disk: when you can reinfect someone so easily, you have it only exist in memory.
But, really, don’t worry about the NSA. The problem is the precedent they set: if you do anything of international economic significance, there is now a UN full of possible attackers.
Oh, minor nit, I’m a researcher at the International Computer Science Institute (in Berkeley) and a visiting researcher at UCSD. All opinions are my own.
