Apple CEO Tim Cook has been in recent discussions with a top Chinese government official concerning security, Reuters reports. The meeting comes following a report that Apple users in China have been targeted in a “sophisticated and widespread” attack by hackers looking to access private user data stored in iCloud. The report was released by Chinese web monitoring group Greatfire.org, which has also claimed that the Chinese government is involved in the hack—a claim strongly refuted by the Chinese government. Cook and Vice Premier Ma Kai met Wednesday in Zhongnanhai to discuss “protection of users’ information” and “strengthening cooperation and in information and communication fields,” according to the official Xinhua news agency. Apple also appears to have rerouted user data on Tuesday to circumvent the hack, Greatfire told Reuters.
