What does the term "logical extraction" refer to in mobile forensics?

Logical extraction in mobile forensics refers to the process of extracting data that is accessible through the device's interface, such as files, contacts, messages, and application data which are viewable without needing to access the deeper, more complex file systems of the device. This method typically uses the device's operating system to retrieve information, leveraging its built-in features and APIs to access data that is not protected by encryption or other barriers.

The focus on extracting only what is readily accessible through the user interface allows for a quicker and often easier retrieval process compared to other methods that may require more intensive resources or technical skills. Logical extraction can yield a good amount of relevant evidence for investigations, especially when data integrity and preservation are of utmost concern.

On the other hand, methods like cloning the entire device or recovering deleted files would fall under different processes in mobile forensics, such as physical extraction or file recovery techniques, which are not focused solely on accessible data. Accessing hidden data would typically require a more invasive approach and specific tools, while cloning encompasses copying all data, not just accessible content.
