U.S. President Barack Obama
The U.S. government was subjected to a massive, unprecedented hack that is being referred to as the biggest in the nation's history. The hack swiped the information of federal employees, which experts believe can be used to blackmail them into subversive activities against the U.S. government. News reports have stated the U.S. government believes the Chinese government is behind the hack. For many years, the U.S. government has engaged in spying activities against the Chinese government, which also includes hacks.
The Chinese government has not stated they were behind the hacks. The U.S. government recently admitted the North Korean government was behind the widespread hack of Sony in America. The U.S. government stated they know it is the North Korean government, due to the fact the U.S. government has been actively hacking the computers of the North Korean government. So basically, what you have here is world governments spying on other world governments.
