In his battle with the United States, Vladimir Putin has a new target — Microsoft.
The Kremlin is backing a plan to rid government offices and state-controlled companies of all foreign software, starting with Moscow city government replacing Microsoft products with Russian ones, according to a senior U.S. intelligence official.
This week, Russia also blocked LinkedIn, the U.S.-based networking site that Microsoft is in the process of buying.
The intelligence official said Putin is going after Microsoft because it is the biggest American name in information technology and because it's easy to convince Russians that the company works with the U.S. intelligence community.
A sensitive U.S. Homeland Security document obtained by NBC News confirms that a Microsoft Office attachment was used by Russian hackers to shut down the Ukraine electrical grid last year.
