Nothing is 100% safe in digital world. Wallet can be hacked but you can prevent this hacking by taking necessary steps. Use strong password and do not share your wallet info to others.
I know we all aware of that certain things but I don't know why people still may just fall into hackers hands and letting them to used control of our keys. May just because some of us wanting easy money and quick returns without knowing that those are just a scam and could lead them into nothing but having their money out from their wallet.
