I understand your concern, but it isn't something that you need to worry about. Yes there is a private/public key pair according to some cipher, but nobody is going to figure out your private key from your public key.
The biggest threat is people gaining access to your machine/private information through poor security practice (human's are usually the weak link in security). If somebody gets these details through poor security then all they need to do is walk straight through the door to your precious coins.
Stay safe

Yes, if you have an unencrypted wallet and somebody steals it that's a bummer. Even if encrypted and you use '12345' as a password still not good. I guess you're only as safe as your password is, right?
Cold storage is the solution.
But more than likely there is bad security practice, allowing the bad guy to walk straight in lol.
