It was not the first iCloud hack in 2014, however, attack on iCloud in China was more complicated than this from September 2014, when naked celebrities’ photos leaked, because one of the vital reasons was low-level in cybersecurity caused by using "The Great Firewall" by Chinese government and other factors such as forcing less-protected technologies. It shows, how politics aspects can participate in daily life and safety of the biggest society at the world. Additionally, this incident shows that, even one of the biggest IT company can have a trouble with providing safety to their customers.
