The Wall Street Journal reports that "Apple said in a statement on its website that it is aware of 'intermittent organized network attacks' aimed at obtaining user information from iCloud.com. The company added that the attacks don’t compromise the company’s iCloud servers and don’t affect iCloud sign-in on Apple devices running its iOS mobile software or Macs running OS X Yosemite using its Safari browser.

Apple said users should not sign into iCloud.com if they receive a warning from their browser that it is not a trusted site. This suggests that the user has been compromised. Apple did not mention China in its statement."  For more, read the full written report (Subscription Required).

CNBC is reporting that a "Chinese web monitoring group said hackers tried stealing user credentials on iCloud's storage and backup service in China. The Chinese non-profit watchdog site, Greatfire.org, alleged that Chinese government authorities may have been involved in the attacks."

In an earlier report, CNBC noted that China's Foreign Ministry's spokeswoman Hua Chunying told a daily news briefing that Beijing was "resolutely opposed" to hacking. She said the Chinese government itself was a major victim of such attacks.
