CYBERWARFARE: When Estonian authorities decided to take down a Soviet war memorial, they might have expected a few protests from the Baltic country’s ethnic Russian minority. An all-out cyberwar seemed less likely. Yet since the end of April, more than 100 separate attacks have hit Estonia’s computer systems. Estonia, known as E-stonia because of its sophisticated use of the Internet, has accused Russia of orchestrating the strikes. The Kremlin has denied any involvement.
