Mobile Forensics Investigation using Cellebrite UFED

The manifold increase in the mobile penetration amongst the world population has interested people from all works of life namely mobile manufactures, service providers, application developers and more to this industry. Thequantum jump inthe user base and its usage of mobile has even caught the eye of Forensic Experts.

In this article we will conduct a mobile investigation of ONE Plus mobile model by applying Cellebrite UFED software.

As a preliminary process, adjustments need to be undertaken on the mobile model under surveillance. The investigator attaches the mobile to his/her laptop through the phone cable.The investigator needs to open the ‘About Phone’ section under Setting and scroll down the various options till he reaches the ‘Build Option’, he needs to tap the ‘Build Option’ seven (7) times which opens a new section – the ‘Developer Option’. Before commencing Cellebrite software, the investigator must check whether the mobile commands ‘Stay Awake’ and Debugging (USB debugging) are ON.

After completing the following steps, the investigator inserts the licensed Cellebrite USB Key in the laptop which displays five choices namely- Mobile device, SIM Card, USB device or Memory Card, UFED Camera and Device Tool.

We choose ONE Plus mobile model to demonstrate the Cellebrite software. After configuration the software on the laptop, the software displayed seven ONE Plus models to select our model.

Since our mobile is ONE Plus 3 A3003 model, we put it for the forensic investigation. In order to gather information, the Cellebrite software provided us with five ‘Extraction’ choices ranging from Logical Extraction, File System Extraction, Physical Extraction (Root), Capture Images, Capture Screen Shots which are easy to understand and implement.

It is recommended that the investigator must click on Logical Extraction followed by Physical Extraction to gather information.

For our demonstration, we selected the Logical Extraction and selected three types of information from the Phone Memory likePhone (Phone Book), SIM (Phone Book) and Phone (Content) and press Next.

The Logical Extraction gave a further choice to select the type of information from the Phone Memory namely Contacts, SMS, MMS, Calendar, Apps Data, Pictures, Audio/Music, Videos, Ringtones and Call Logs. 

The software sends a ‘pop up’ message and in order to move further the investigator needs to click on YES. 

From the Contacts account we extracted contacts from Gmail, Face book messenger and Whatsapp as displayed below.

The Cellebrite software provides the investigator with source instructions to proceed further on the case by just clicking on the ‘How to?’

The Logical Phone Extraction was completed successfully. The details of the number of information gathered from Phonebook, SMS, and Call Logs from the mobile under forensic investigation is highlighted.

The software displays another pop up ‘PA Evidence Collection.ufdx’ along with the Logical 01 folder for the investigator

The UFED Physical Analyzer report of the mobile phone was captured by Cellebrite. The analyser  captured content of the mobile model information ranging from the model name, IMEI, ICCID, MSISDN, IMSI  to name a few.

Before making the final report, a case management form needs to be filled up by the investigator which provides –the case number, name, evidence number, examiner name, department, location, notes, name of the report, document details, project name as well as format. The report will be submitted in PDF or word or any other format. The final report is generated by pressing Next command.

3 Ways to Mount a RAW Image in Windows

In Forensic, to investigate a hard drive or disks we always make a forensic image. A Forensic Image is a forensically sound and complete copy of a hard drive or other digital media, generally intended for use as evidence. Copies include unallocated space, slack space, and boot record.  Many computer forensic programs, especially the all-in-one suites, use their own file formats to store information. These images are stored in a format of RAW file or AFF or E01.

RAW Image Format: This format is a RAW bit-by-bit copy of the original. It is often accompanied by Meta data stored in separate formats. This Image Format is most common used and is read by every Forensic tool in the industry.

Once the RAW image is created, it can’t be read unless it is mounted by a tool. Mount is the process that will take the raw logical image and mount it onto a specified directory of choice to be able to examine the contents of that image. The image has to include be a recognizable file system as a partition. This makes invocation of the command interesting as the raw image is a physical disk image and not a specific partition of a file system.
