My thoughts exactly. A successful hack job or covert operation is one that you don't hear about. Non-detection is one of the goals and one of the criteria for defining success. So the ones that are found out, should be assumed to be the low end of the competency/success scale. Edit: Sort of a form of survivorship bias going on. The ones that "survive" (i.e. get found out) can't be used to draw conclusions about the others.
