Ukrainian presidential website under attack

The website of the Ukrainian President Viktor Yushchenko has been suffering a prolonged distributed denial of service attack, according to a post on antivirus vendor F-Secure's blog.

According to F-Secure, Russian groups are being blamed for the attack, in a case which the company says has similarities to the attacks against Estonia in the spring.

Last week Mikhel Tammet, director of the Estonian communication and information technology department, told ZDNet .co.uk he believed forces within the Russian government may have initiated and sponsored attacks against his country's critical national infrastructure earlier this year.
