There's a lot of intelligent individuals especially hackers now a days. For me, I think bitcoin assures the security of their users so they come up of having paper wallet etc. So in our part maybe we should think a strongest password and make sure to always logout and dont share personal info:) to prevent this kind of event.
That's basic internet security tips. I learned those things a long, long time ago and my children learned them in grade school. I don't think there are many people who don't have some kind of knowledge when it comes to these basics, but actually applying the knowledge is a completely different story. Most of the time it just comes down to not going to sketchy sites, have 2FA enabled and don't use online wallets if you really want to have dedicated security for your wallet. Cold storage will always beat any password or security system that you try to implant.
Bitcoin can potentially be broken by using a brute force attack, much like any other protection system based on keys. I believe that is still a long way away to happen.
