You may or may not have picked up the news that Estonia came under cyber-attack in early May. … The almost unanswerable question is whether it was the Russian government that launched the attack or whether it was Russian hackers. Estonia, it seems, provoked the attack when the Estonian government removed a statue (in Tallinn) that commemorates Soviet troops who were killed fighting the Nazis. Estonian officials claim some of the attacking computers had Kremlin IP addresses, but – and I’m sure the Russians would suggest this – such computers could have been infected by viruses and used as bots by Russian hackers. That’s what you call plausible deniability.
