Moscow’s Federation Tower is not particularly famous outside Russia, yet thousands of ransomware victims across the world might have an unwelcome connection to some of the companies operating from within its shimmering glass walls.

It’s no secret that the sums demanded by ransomware extortionists have become more outrageous over the last three years. Ransomware started out as a crime against home users, with ransoms in the tens to hundreds of dollars at most.
