Abstract:
---------------
Embedded hardware is getting harder and harder to reverse. Leading manufacturers are getting better at disabling JTAG and UART. BGA chips, integrated packages, and encrypted firmware (both in updates and at rest) are making it harder to peek under the hood and see how these systems are built. Reverse engineering cannot begin without decrypted firmware.
This talk presents a Cryo-Mechanical RAM Content Extraction Robot we built to grab decrypted RAM contents off of DDR1|2|3 memory modules. It will talk through the challenges faced building the robot, as well as how we designed and built a robot that keeps RAM cool at -50 Celcius without breaking PCBs, shorting the board, or risking bodily harm. Finally, it will discuss the practical nuts and bolts of building such a robot within a thousand-dollar hardware budget.
