Yes of course, there are so many cases of hackers hacks an individual's wallet. And I think the main reason why it happened is that because they are not so careful about their private things, or they got into a site and click a link in which they are unaware that it is a bomb that will explode once it is been click. The way of hackers to get into you is through different kind of techniques, using viruses, key logger, etc.. So we always need to be careful.
