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.
Security for your coins so that others can not access your funds is the most important thing you want to know when holding on your bitcoin or other cryptocurrencies. strong paswords, clean computers, hardware devices, paperwallets, 2FA, secure internet access... all are important.
