The Finnish National Bureau of Investigation has not been able to figure out who did it. "The blackmailer had gotten hold of the Symbian encryption key used for signing. The code is a few kilobytes in size. Had the key been leaked, Nokia would not have been able to ensure that the phones accept only applications approved by the company."
