Microsoft said Tuesday it has shut down another six websites created by hackers linked to Russia's military intelligence, with the newest targets the U.S. Senate and two conservative think tanks critical of Russia and President Trump, the Hudson Institute and the International Republican Institute. Microsoft won a court order last year to shut down fake web domains created by the hacking group it calls Strontium, also known as Fancy Bear and APT 28, and including the six just shuttered, the company has used this legal authority to shut down 84 fake Strontium-created sites. "We are now seeing another uptick in attacks," Microsoft President and chief legal officer Brad Smith told The New York Times on Monday.
