Microsoft digital certificate stolen

From an MSNBC story: "Microsoft Corp. issued a warning Thursday to all its customers that a computer criminal has obtained a digital certificate with the company's name and authority. The equivalent of a royal seal, digital certificates prove software code was written by a particular company and is safe. Microsoft said the criminal tricked Verisign Inc. into issuing two of the certificates. The software giant is warning users to be suspicious of any program that arrives with a certificate claiming Microsoft's authority."

Update: Thanks to the many readers who pointed out the presumably unintended irony in the last sentence of the quote. :)
