Is anyone actually surprised? Even military has USCYBERCOM. What do you think their type of 'weapons' are? My only surprise it that this has leaked.
Not to mention that before Obama left office he made intel sharing between these agencies and domestic agencies even easier. So this can't easily be dismissed as 'not surprising that spy agencies are hacking foreign entities'.
This just provides further insight into how widespread these powerful tools are within the US government.
Whether it's surprising or not is not really the only relevant question.
