Google's blogging tool, Blogger, is suffering from a severe case of hackeritis. Hundreds of blogs were updated with short posts containing links to virus-laden downloads that either mine hard drives for personal data or turn the PC into a zombie to help propagate the attacks. Google is mum on the attack, and security experts haven't determined whether the hackers discovered a security flaw in Blogger or simply set up false blogs. It's apparently impossible to make the distinction, which should tell you something about the quality of most of the posts on Blogger.
