I think that you will not return what you lost. The security issue is very important, more attention needs to be paid to this.
Once you lost it, there is no other way to return it, a hacker wont ever return what he gets from other crypto users. Making sure of the security of our wallet is our own responsibility, we should be careful everytime and taking care of it should be the priority. It is the holder of our coins we should never leaked any information of it.
