According to reports, last week's 'denial-of-service' (DoS) attack that disrupted the Twitter micro-blogging site, caused problems for Facebook and LiveJournal, abd affected millions of Internet users worldwide, was aimed at a Georgian blogger who goes by the name 'Cyxymu.'

Apparently, Cyxymu is the Cyrillic spelling of the town Sukhumi, the rebel center of Georgia's disentangled Black Sea region of Abkhazia. Reports say that the blogger, Georgy Jakhaia, is a 34-year-old economics professor, and a refugee from Sukhumi living in the Georgian capital Tbilisi. He is supposedly an active critic of Russsia's politics in the Caucasus region. 

Commenting on the target of the DoS attack, Twitter's co-founder, Biz Stone, said in a recent blog post: "The massively coordinated attacks on Twitter this week appear to have been geopolitical in motivation."

The attack, which hit the Twitter service last Thursday at 9:00 am ET, was targeted on the sole blogger, with 'Bots' taking over thousands of computers and reportedly pointed them all to Cyxymu's Twitter account. The crashed computers aggravated Twitter's overload problem and further spelled trouble for Facebook and LiveJournal. 

With the attack on one particular blogger leading to the disruption of service of a popular social networking site, affecting nearly 44 million users - raises fresh questions about a pertinent issue - cyber security, more so with countless banking, medical, and company statistics being regularly posted online!
