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.
The truth is that the btc wallet security is very high however I have seen fake emails fooling you into offering you keystore files or anything that could open your wallet, beware. Also your account on the forum is very easy to be stolen.
