Spying on each other is the meat and potatoes of all national intelligence agencies. We do it, the Russians do it, the Chinese, etc.. Nothing earth shattering here. I suspect that both (all) sides are thoroughly infiltrated and with supplemental technical means there are very few real secrets to be found. Only the sheer quantity of such material offers at least temporary confidentiality.
