DF WK 12 Mobile Device Forensics
What is mobile device forensics?
Mobile device forensics is the science of recovering digital evidence from a mobile device under forensically sound conditions.
What are the primary goals of mobile device forensics?
The primary goals are to recover, analyze, and preserve digital evidence from mobile devices to ensure it can be used in legal proceedings.
Name three types of data typically recovered during mobile device forensics.
Call logs, text messages (SMS/MMS), and app data (e.g., WhatsApp, social media).
What is the first step in the mobile device forensics process?
The first step is to secure the device to prevent any tampering or loss of data.
What does the term “chain of custody” mean in mobile device forensics
A Chain of custody refers to the documentation process that tracks the seizure, custody, control, transfer, analysis, and disposition of the evidence.
What is the importance of putting a mobile device in “Airplane Mode” during forensic analysis?
Airplane Mode disables all wireless communications, preventing remote wiping or data tampering while preserving the evidence on the device.
What is the difference between logical and physical extraction in mobile forensics?
Logical extraction retrieves active data like contacts and messages, while physical extraction can recover all data on the device, including deleted files.
Name a tool commonly used for mobile device forensics.
Cellebrite UFED is a commonly used tool for extracting data from mobile devices.
Why is it important to consider encryption in mobile device forensics?
Encryption can protect data on a mobile device, making it challenging to access without the correct decryption keys or techniques.
What is a SIM card’s role in mobile device forensics?
A SIM card stores subscriber information, call logs, text messages, and can be a vital source of evidence.
What is the significance of IMEI in mobile forensics?
The IMEI (International Mobile Equipment Identity) is a unique identifier for mobile devices, useful for tracking and identifying a device.
What is a “Faraday bag,” and why is it used in mobile device forensics?
A Faraday bag is a container that blocks radio signals, preventing a mobile device from sending or receiving data during forensic analysis.
What are “artifacts” in the context of mobile device forensics?
Artifacts are pieces of digital evidence such as logs, cached files, or remnants of deleted data that provide information about a user’s activity.
What is the role of metadata in mobile device forensics?
Metadata provides information about other data, such as timestamps, GPS locations, and file creation details, which can be crucial in an investigation.
Why is it important to document the forensic process in mobile device forensics?
Documentation is critical to ensuring the integrity of the evidence, enabling the forensic process to be replicated or reviewed in legal proceedings.
