There was a fascinating story in yesterday's Guardian about how the Russian government has been accused of orchestrating a major cyber-attack on Estonia over the last three weeks.
Although similar cyber-wars have been allegedly staged between country pairs such as Indian and Pakistan, plus Taiwan and China in the past, this is the first instance of it happening in Europe.
And, as you might expect, the NATO bigwigs are in a tizzy about it.
The simmering row between the two countries started escalating last month when the Estonian government removed the Bronze Soldier Soviet war memorial in central Tallinn.
