Apple believes that the reason hackers can get so many photos is the result of long-term social workers. Login icloud System In addition to input account number, password, there are other means to login: correct input e-mail address, birthday and answer three security questions two.

However, just a day before the scandal, the Defcon conference in St Petersburg, Russia, revealed that the iphone and icloud were hackapp by two security experts from the company. The problem is not to limit the number of user logons and the simplistic security Code (only 4 digits). The conclusion is that this could lead to hackers breaking the intrusion system through brute force.

icloud system due to a number of security protection measures are imperfect, there is no limit to the number of user login attempts, as well as the security code too short and other hidden dangers, resulting in the icloud system was successfully cracked.

At the same time, a considerable number of people have always held this view: 1 cloud computing has never been advertised as completely safe; 2 cloud computing will continue to grow. Security is not a selling point, and features and prices are the selling points.
