Systems that hide their firmware-- often deep in readout-protected flash or hidden in encrypted ROM chips-- have long stymied reverse engineers, who often have to resort to inventive methods to understand closed systems. To help reduce the effort needed to get a foothold into a new system, we present GlitchKit-- an open source hardware and firmware solution that significantly simplifies the process of fault-injecting your way into a new system -- and of fault-injecting firmware secrets out! This talk presents the development completed thus far, demonstrates the use of GlitchKit in simple attacks, and invites participation in the development of our open-source tools.
