But if you treat well funded actors as essentially omnipotent entities, you might just as well lie down and give up. The reality is that although we don't know everything, there cannot be all that much activity, either, or we would see many more installations of well crafted exploits and rootkits than what currently gets reported. And I would expect blackhats to go for some reliable 0 day hack with small code size rather than relying on a complex attack that first needs to read memory locations in a roundabout way to get anywhere.
