We’d like to present a story about hacking a 14 years old Toshiba laptop in order to create a keygen for their BIOS password recovery mechanism. As an unexpected bonus we’ve obtained the EC firmware signing keys. This allows us to plant a stealth and persistent rootkit on the laptop. We will also have a look about how this relates to their newest laptop models.
