When their privacy guru website got hacked… =))
Quote from http://blogs.zdnet.com/security/?p=617
IdentityBlog.com, a Web site run by Microsoft’s chief architect of identity and access, has been hacked and defaced.
The site, which is used by Microsoft’s Kim Cameron to promote discussion around privacy, access and security issues, now contains an “owned by me” message and a link to a third-party site (see screenshot).
The last entry at IdentityBlog.com (Google cache) is dated October 27, 2007, which suggests the site hijack occurred over the weekend.
