There's a lot of intelligent individuals especially hackers now a days. For me, I think bitcoin assures the security of their users so they come up of having paper wallet etc. So in our part maybe we should think a strongest password and make sure to always logout and dont share personal info:) to prevent this kind of event.
This is pretty much a general rule for everything you do on the internet. Bitcoin can be hacked, but, not in the in way you meant. People can be hacked, that's you wanted to say.
