according to my opinion everything that is made by people also can be break by people so everything is possible and the only solution is to keep yourinformation for yourself and do not give more chances to the hackers.
Yes, you are right with your statement. Hackers now are really clever and can do all things over the internet. The best thing to do now is always keeps our wallet safe and secured.
Hackers only hack because we give them a chance to hack our bitcoin, if we will not give them opportunity to hack our account then they will not be able to hack it, so to avoid this kind of problem, we all should use the safe bitcoin wallet and never invest in scamming site, before investing do research and use wallets specially the blockchain to save our bitcoin for long time, never share your private key with anyone.
