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?
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
Running a memory dump tool from the operating system while the device is booted
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.
