Yesterday, I found my Evernote application was not working. I immediately changed my password of Evernote.
Actually, Evernote had been hacked and 50 million passwords were stolen.

Network security is a very important matter now. We are highly dependent on internet connection. If the internet were crippled during one day, a lot of people would be critically damaged.
Needless to say, most companies are taking measures against network cracking. However, I experienced some surprising cases recently.
For example, Sony was hacked and had to stop the service of PlayStation Network for a few months occurred in 2011.

The cracker has not been clarified. Some members Anonymous were arrested to be released soon because of lack of evidence.
I cannot imagine the loss of Sony caused by the case. Cost for check and maintain of system, civil action and compensation and chance loss of sales are almost incalculable.
On the other hand, I do not know the merit for the cracker.
In general, goal of the professional crackers is to acquire personal information of customers. I heard some providers buy lists of personal information from crackers. But Sony or Evernote is too big to be dealt with. How much is the cost of the list of customers of Sony?
Nowadays, big data including personal information is growing more and more. At the same time, security risk and the scale of the accident are greater than they ever have been. We face great risk in exchange for convenience.
