True, hackers never rest, they always try to exploit something exploitable and even resort to some dirty strategies.  They have lots of way to hack our account.  Just for example some phishing email that mimic the original site of a reputable website, the only difference is the address but if you are not keen on observation, you will not notice it.  I had received lots of these in my email and almost made me click the link but I noticed that it was not the original sites link.
