Symbian encryption keys were once held for ransom, Nokia paid millions

Nokia’s smartphones were run by the Symbian operating system. In 2007, during the time when Nokia was offering devices like the E61i, and the N95, a blackmailer managed to acquire the encryption key to the operating system, a file only a few kilobytes in size.
Nokia paid the demanded ransom, for which the blackmailer promised that the keys would not be used improperly. Of course, the payment was made after the authorities were alerted, so when Nokia delivered the bag of cash in Tampere, Finland, law enforcement intended to follow whomever made the pick-up. Unfortunately, the perpetrator gave them the slip and escaped with the cash. The case is still open and unsolved.
