Russian hackers blamed for cyber attack that leaked Obama's schedule

A recent cyber-attack on the State Department was reportedly carried out by high-level Russia hackers who also penetrated restricted parts of the White House computer system, such as the president's private schedule.

CNN reported Tuesday, citing US officials briefed on the months-long investigation conducted by the FBI and Secret Service, that the hackers were able to access real-time, non-public schedule of President Obama, which is regarded as highly sensitive information that is sought after by foreign intelligence agencies.

In October 2014, the White House acknowledged that there had been suspicious activity on its unclassified network serving the executive office, prompting system shutdowns and security upgrades.
