It's an alarming new hi-tech war-fighting weapon. It was tried last year but the culprits have never been identified.
A three-week wave of massive cyber-attacks on the small Baltic country of Estonia is the first known incidence of such an assault on a state. The Western European Union will examine the consequences in Paris tomorrow.
There has been no love lost between Estonia and Russia since this small country gained independence. Last year the Russians were furious when a memorial to 'liberating' Russian Soldiers was removed from its prominent site in Tallinn.
Estonia was hit with a barrage of cyber warfare, disabling the websites of government ministries, political parties, newspapers, banks, and companies. Telephones, televisions, computers and the internet collapsed.
The crisis unleashed a wave of so-called DDoS, or Distributed Denial of Service, attacks, where websites are suddenly swamped by tens of thousands of visits, jamming and disabling them by overcrowding the bandwidths for the servers running the sites.
The attacks have been pouring in from all over the world, but Estonian officials and computer security experts say that, particularly in the early phase, some attackers were identified by their internet addresses - many of which were Russian, and some of which were from Russian state institutions.
"The cyber-attacks are from Russia. There is no question. It's political," said Merit Kopli, editor of Postimees, one of the two main newspapers in Estonia, whose website has been targeted and has been inaccessible to international visitors for a week.
If anything relations have deteriorated since last year between Russia and its former satellite states. This is just one tool in the armoury of cyber weapons that are almost certainly available to the major power
At present, Nato does not define cyber-attacks as a clear military action. This means that the provisions of NATO self-defence do not apply. A cyber attack is not defined as warfare.
Estonia is one of the most wired societies in Europe and a pioneer in the development of "e-government". Being highly dependent on computers, it is also highly vulnerable to cyber-attack.
The attacks came in three waves in April and May last year. It is believed that this was a minor attack even though it closed down the country for weeks. The effects on similar attacks on military equipment could be catastrophic in future conflicts.
Tomorrow we will have new worries but few new solutions.
To get from the first link on the chain to the final one took nine long months. While the soldiers were ready for action, the bureaucrats moved at a snail's pace through five European centres. There were 177 visits from Paris to Brussels. No electronic communications?
The mission was to provide peace keepers for Chad. The waiting soldiers were cursed with the bureaucratic nightmare. The report is a complacent one. It suggests as a remedy that a new sixth link be added to the chain.
It would be better, I was told today, because the sixth centre will be more 'rounded.' Huh? The chain will be even longer.
