The distributed denial of service attack on Thursday that targeted Twitter, Facebook, LiveJournal and several Google sites may have been politically motivated.

The reported target of these attacks was a blogger named Cyxymu from the Eastern European country of Georgia who is an outspoken supporter of his country. Facebook’s chief security officer, Max Kelly has said the attack was coordinated to “keep his [Cxymu's] voice from being heard,” according to Cnet.

If Kelly is right, then the cyber attack may have been coordinated by Russian hackers or those with Russian sympathies. Tensions have been heightened between Russia and Georgia since last year’s brief war between the two countries over the contested region of South Ossetia. There is no clear evidence as to who perpetrated yesterday’s cyber attack, but Cxyxmu earlier today suggested the attack was perpetrated by the KGB–the now-defunct security agency for the former Soviet Union.

Although yesterday’s DoS attack targeted a wide range of social network and blogging sites, it was only Twitter that suffered a significant outage. Facebook and LiveJournal suffered slowdowns as a result of the attack, while Google users were not significantly impacted. Kelly reportedly told Cnet that it was able to maintain access to Cxymu’s profile for users in the Georgian region, but the Facebook profile was inaccessible in other parts of the world.
