Microsoft this weekend unleashed its wrath on the National Security Agency, alleging it was responsible for the ransomware attack that began last week and has spread to thousands of corporate, government and individual computer systems around the world. Microsoft Chief Legal Officer Brad Smith launched a blistering attack on the NSA and governments worldwide, equating the ransomware attack with the U.S. military allowing the theft of a Tomahawk missile cache. "This is an emerging pattern in 2017," Smith wrote Sunday in an online post.
