An investigator obtains a custom-built device suspected of storing code on its embedded components. Which approach is most likely to produce comprehensive details for an in-depth review?
Running a memory dump tool from the operating system while the device is booted
Copying application logs and files to an external storage for offline inspection
Reinstalling the firmware before analyzing it with a software-based script
Attaching a hardware probe to the debug interface for a bit-by-bit memory acquisition
Accessing memory through a hardware debug interface provides full visibility into embedded system data, including volatile memory and hidden regions inaccessible to OS-level tools. This method avoids dependency on potentially compromised firmware and ensures a comprehensive snapshot. Relying on system utilities or logs risks incomplete data capture and omits critical forensic artifacts.
