Still not sure what to make of the current situation in Eastern Europe, where cyberattacks against Estonian infrastructure coincided with other political events across the country.

The Kremlin has denied any involvement in the cyberattacks, which began last month about the time Estonian officials removed a statue dedicated to Russian World War II victims of the Nazis from a town square.

According to this report in the Wall Street Journal, Estonia is an attractive target for cyberattackers because more than two-thirds of the population uses broadband and more than 80 percent files income taxes online.
