>Not if this is one of a few dozen or few hundred similar ongoing operations. The risk is always there, they have to expect some amount of failure.
That actually makes me think it's not happening at a larger scale, since we'd likely have heard of at least a few similarly elaborate cases being uncovered by now. If not during the attempt itself, then at least at some later point in time.
Either almost all of these operations remain undetected, because they are even more sophisticated and much of the world's software ecosystem has been secretly compromised for years or there aren't actually that many such operations.
