This case was quite interesting. We received this strange broken flash drive that used an eMMC chip as its storage chip, what was more strange, is that the USB drive also contained an external controller. This type of configuration is unique, this is due to the fact that the eMMC chip already comes with an embedded controller, and the external controller was either redundant or was there for a different reason.
After some investigation, we discovered that the controller had a purpose and it was to act as a USB 3.0 bridge and to encrypt the data between the eMMC and the host.
Watch our video below and see how we managed to save thousands of encrypted documents by using a donor flash drive.
