Update: Three hours of sleep is not your friend. I had a very old Slashdot posting. (Thanks, Anil.)

According to BBC News, Blogger has been hacked.

Google’s Blogger site is being used by malicious hackers who are posting fake entries to some blogs.

The fake entries contain weblinks that lead to booby-trapped downloads that could infect a Windows PC.

Infected computers are being hijacked by the gang behind the attacks and either mined for saleable data or used for other attacks.

Update from Eric at Blogger (see comments).

Blogger was not compromised. Instead, the blog posts are from users whose machines were compromised by a virus. These users had their mail2blogger addresses in their computers’ address books (a perfectly legitimate use case), which the virus then spammed with its content.
