What is Mobile Phone Forensics? A Detailed Guide 2024

Part 1. Introduction to Mobile Phone Forensics

Mobile phone forensics is also known as mobile forensics. It is about getting information from mobile devices like tablets and smartphones. This can include things like app data, deleted files, GPS locations, text messages, call logs, photos, and videos.

This type of forensics is often used in criminal investigations to find evidence. Mobile forensic investigators need to ensure the data they get can be used in court.

Mobile device forensics has a connection with other digital forensics areas. For example, malware analysis, computer forensics, and network forensics. However, mobile forensics focuses on mobile devices.

That’s why mobile device forensic analysts need to know a lot about mobile devices. This includes knowledge of systems and how to get data out of them. They use various software and tools for this.

Part 2. Why is Mobile Phone Forensics Important?

Mobile phones carry a significant amount of information. The data can help to understand the full scope and picture of a digital attack. That’s why mobile forensics is extremely important.

In 2021, guess how many mobile devices were active worldwide? 15 million. That’s nearly two mobile devices per person. The amount of data stored across all these devices is astonishing.

One significant difference between traditional computer and cell phone forensics is that systems are interconnected now. Commonly used devices like cars, phones, cameras, and doorbells are no longer isolated. They can operate under one network.

You might be wondering how this process occurs. Let’s have a closer look at its steps.

Part 3. What Are the Steps of the Mobile Device Forensics Process?

Following are the general steps to follow during a forensic investigation.

Device Seizure:

First of all, the mobile phone is seized from its user. At this particular stage, forensic investigators should also start documenting the chain of custody. For example, the complete records of who and when handles the device. If the device is used in a criminal investigation, a search warrant is usually needed.

Device Acquisition:

Forensic investigators create a sector-level duplicate of the device. This process is known as imaging or acquisition. The original device and the original device are passed through a hashing function. Then, their outputs are compared to make sure that it is an exact copy. Next, cell phone forensic experts decide on the investigation’s proper goals and approach.

Device Analysis

Investigators start working on the device image. So they can confirm a search or hypothesis for hidden data. Then, investigators use specialized tools to find and recover information. Data may be located within the accessible deleted disk space, hard disk space, or the operating system cache.

Reporting:

After getting the data, forensic investigators store and analyze it to reconstruct a plausible version of events. A report is ready, which may be technical or non-technical. It depends on the audience.

Now, let’s discuss the next part of our discussion!

Part 4. What Are the Tools and Techniques Used in Mobile Phone Forensics?

Cell phone forensic experts use various tools and techniques to analyze devices. For instance, there are various ways to extract information from a mobile device.

Logical Extraction:

The mobile device is connected to a forensics workstation using a hardware cable or Bluetooth. This approach is relatively simple and quick. However, it is also the most limited. Logical extraction tools include XRY Logical and Oxygen Forensic Device Extractor.

Physical Extraction (Hex Dump):

During smartphone forensics, this involves copying the device’s flash memory bit by bit. This approach is the most common but technically complicated and dependent on the manufacturer. Physical extraction tools include XRY Physical and Cellebrite UFED Physical Pro.

Once investigators made a copy of the device, they used other tools to capture and analyze data.

Besides these traditional methods, Dr.Fone provides valuable tools in this domain. Its Phone Manager feature enables the export of data from both Android and iOS devices to a computer. This includes a variety of data types crucial for forensic phone analysis.
