I don't see how any standard private key could get hacked in today's world.
I mean, in the future when quantum computing comes around we will definitely need to take that into consideration, but in the meanwhile there is not much to worry about if you use the standard private keys.
Even a quantum computer CAN'T get a private key from a bitcoin address because sha256 hash algorithm is quantum resistant.
However a quantum computer can get the private key from the public key, which is visible if you use bitcoin incorrectly and re-use your address. Public key becomes visible, when you have made a single spend action from your address.
All keys are "standard" private keys. Some of them can be weak. eg. "1", or any key that is too simple. If you generate a key truly randomly, then you can get a weak or a strong key.
