Likely not. Anything is possible in the world of computers but honestly 80% of hackers wouldn’t be able to. Most monitoring/hacking activity has to actuated by the user, in plain terms if you don’t download something or turn something on remotely, there isn’t much of a way for them to do it. But the way I look at is, anyone who has the expertise to hack without a user there wouldn’t waste their time. You have to think about what they might want and if it’s worth it for them. So long story short anyone who could, wouldn't, because they know that the average person wouldn’t have anything worth their while as far as effort over profit goes, they would spend a lot of work and time, for little pay out.
