Bah! Looks as though those of us who suspected Vladimir Putin of testing cyberwarfare techniques on plucky little Estonia were wrong. At any rate, this ArsTechnica report says that the DDoS attacks were the work of a single disaffected individual.
Last May, the web sites of a number of high-ranking Estonian politicians and businesses were attacked over a period of several weeks. At the time, relations between Russia and Estonia were chillier than usual, due in part to the Estonian government’s plans to move a World War II-era memorial known as the Bronze Soldier (pictured below at its original location) away from the center of the city and into a cemetery. The country’s plan was controversial, and led to protests that were often led by the country’s ethnic Russian minority. When the cyberattacks occurred, Estonia claimed that Russia was either directly or indirectly involved—an allegation that the Russian government denied. Almost a year later, the Russian government appears to have been telling the truth about its involvement (or lack thereof) in the attacks against Estonia. As InfoWorld reports, an Estonian youth has been arrested for the attacks, and current evidence suggests he was acting independently—prosecutors in Estonia have stated they have no other suspects. Because the attacks were botnet-driven and launched from servers all over the globe, however, it’s impossible to state definitively that only a single individual was involved…
Charles Arthur has a rueful post on this too.
