Mobile Forensic Examiners – How to Preserve Forensic Evidence

A mobile forensic examination is often necessary for a criminal or civil case. The data contained in a mobile device can make all the difference in a case. It is important to work with prosecutors and forensic examiners in advance to establish standard operating procedures and best practices. The purpose of a mobile CSI investigation is to preserve the data on a mobile device for future investigations. This is a critical part of the CSI investigation.

Forensic storage ensures that evidence is admissible and prevents the deletion of important information. With the constant changes in the form factors of mobile devices, operating systems, and peripherals, data can be easily deleted. Fortunately, mobile forensic examinations can retrieve deleted information with legal tools. However, the process is complex and expensive, so only the most experienced forensic investigators should attempt it. Whether you need to recover a phone or a computer is another matter entirely.

There are three basic methods of data acquisition from mobile devices. One of the most popular is the hex dump. This method uses a device’s memory to extract a raw image in binary format. During a hex dump, the forensic examiner connects the device to a forensic workstation and pushes a boot-ladder into the device. This method reveals more information than a traditional hex dump. In addition to hex dumps, mobile forensic specialists can also perform chip-off, which is a method of data extraction directly from the flash memory of a mobile device. This method is the most complicated and requires experience and skill, and can be prone to errors and biases.
