Mobile Forensic Investigation Awareness

Smartphones nowadays can handle tasks that used to need a computer just a few years ago. In reality, the situation has flipped. Many apps are exclusively available on mobile devices, with developers opting out of cross-platform development for PCs completely. While you may use your computer at work and at other times during the day. You do not have continual access to it as you do to your cell phone.

Cell phones are used for everything from making phone calls and sending text messages to moving money and storing sensitive information. Millions of data records are stored on cell phones in the form of emails, messages, images, location data, financial information, and dozens of other types of information. Even if the data has been erased, most of it may be retrieved.

Cell Phone Forensics Analyze Process

Digital evidence is perishable and unreliable. The evidence on a mobile phone may be tampered with or destroyed if it is handled incorrectly. Furthermore, if the mobile phone is not treated according to digital forensics best practices, it may be hard to tell what data was altered and whether the modifications were deliberate or inadvertent. Mobile devices must be evaluated by a skilled expert utilizing mobile device forensic tools to secure the evidence and avoid spoilage.

Identification, collection, acquisition, and preservation are the four steps in the early treatment of digital evidence.

Awareness

The aim and scope of the identification phase are to locate relevant digital evidence for the case. This evidence may be spread over various devices, systems, servers, and cloud accounts. The data on a mobile phone isn’t exclusive to the device itself. The information on the device may be backed up to a PC or synchronized to cloud storage or another mobile device.

Identification needs thorough documentation as well. Documentation is essential throughout the investigation, but particularly at the start since any errors might taint the evidence. The collection step provides us with a flawless picture in time (forensic copy) of the data as it now exists. Because identification comes first and before the acquisition, any errors committed here are carried over to the rest of the process.

Collection

Physical devices, such as smartphones and other mobile devices, are gathered during the collecting phase. Collecting digital evidence may be more difficult than safeguarding conventional forensic evidence since it might span several devices, systems, and servers. There are critical duties that must be carried out in order to safeguard the evidence.

Isolating Device Users

Apart from ensuring that all relevant electronic things are gathered. The major purpose of the collecting procedure is to safeguard digital evidence from contamination. This may be done in a variety of ways, such as separating devices from their users until forensic capture of the mobile device is available. Before the forensic acquisition (a precise picture in time of the mobile phone data) is accomplished, the user might remove, create, or update data while in their possession. They might also do a factory reset or wipe on the device. And erasing part or all of the data on it permanently.

Isolating Devices

We must also separate the gadget itself, in addition to separating the phone from the user. Even when charging overnight on the bedside table, mobile phones are continually sending and receiving data since they are meant for communication. Even if no one physically touches the phone, data may be lost, modified, or destroyed if it is sent.

All types of data transmission, including the cellular network, Bluetooth, wireless networks, and infrared connections, are disabled to establish device isolation. By disconnecting the phone from all networks, it is prohibited from obtaining any new data that might overwrite or remove existing data.

Acquisition

A Mobile forensic Investigator obtains, or forensically copies, data from a mobile device utilizing a number of ways throughout the collection process.

Logical Extraction

Logical data extraction from a mobile phone captures all of the files and directories on the device while leaving no unallocated space. While erased space on a phone cannot be retrieved, deleted data on a phone may be recovered by logical extraction using forensic tools and procedures. This information is stored in a variety of database files, most notably SQLite. Messages, images, video, music, contacts, application data, certain location data, internet history, search history, social media, and other types of data are often acquired using logical extraction.

Extraction of the File System

A logical extraction may be extended to include a file system extraction. It gathers most of the same information as a logical extraction, as well as additional file system information. The forensic tool accesses the internal memory of the mobile phone during a file system extraction. This means that it may gather system files, logs, and database files from the device that a logical acquisition cannot.

On a mobile phone, most programs save their data in database files. More lost data, such as database files and data relating to programs used on the device, may be retrieved using a file system extraction since it recovers more of these database files.

Extraction Through Physical Means

The whole contents of a mobile phone are recorded when it is physically retrieved, including all files, user content, deleted data, and unallocated space. While this is the most comprehensive extraction approach, it is also the least well-supported. A physical extraction, like forensic imaging of a computer hard disk, generates a bit-by-bit replica of the mobile phone’s full contents.

The logical and file system contents, as well as unallocated space, are restored via a bit-by-bit copy. This extraction approach enables forensic examiners to retrieve deleted data such as location information, email, messages, videos, images, music, programs, and nearly any other data stored on a mobile phone that would otherwise be unreachable.

Files to Back Up

A file is created when you connect your mobile phone to a computer to make a backup of your device. This file may be fed into cell phone forensics software and evaluated similarly to a forensic phone extraction. Even if the data on the phone has been destroyed or the phone has gone missing, there is always hope. The evidence you need in the case may still be in the backup file.

Cloud Data

Companies that specialize in mobile phone forensics have created solutions that enable users to access and acquire data stored in the cloud. Cellebrite, the leading vendor of mobile phone forensic tools, can capture cloud data from both cloud backups and cloud-based apps. While a forensic photograph of a mobile phone may be a treasure mine of information. The ability to utilize that information to uncover even more evidence in the cloud is a substantial force multiplier.

Preservation

To guarantee that evidence is acceptable in court. The integrity of the mobile phone and the data on it must be verified.

Chain of Custody

The purpose of evidence preservation is to prevent tampering with digital evidence. First responders, detectives, crime scene technicians, digital forensic specialists, and everyone else who comes into contact with the device must ensure that it is handled correctly. Throughout the life cycle of a case, a chain of custody must be maintained.

Hashing Algorithm for Mathematicians

Because data is extracted from the device rather than an exact bit-for-bit replica of the evidence item. The forensic data collecting method from the mobile device is best referred to as “forensics extraction.” The forensic program cannot access specific regions of data when the phone is turned on. Data that is inaccessible because the mobile device is turned on, on the other hand, is frequently of little to no value. The hashing procedure happens after the forensic copying. A mathematical process is used to the duplicated data, yielding a one-of-a-kind hash value. This hash value may be compared to a digital fingerprint since it uniquely identifies the duplicated evidence as it exists at the moment.

Reporting

A report of the data on the mobile device will be created if the customer requests it. Our examiners may find it more convenient to export all of the data from a mobile phone for counsel’s perusal. We formatted this export to make it as accessible as possible, with the option to search and filter the information.

A more detail to report may be required when dates, data kinds, or sorts of specific forensic artifacts must discuss in order to convey the narrative of what transpired in a case.

Expert Testimony

Everything that goes into a mobile forensic investigator culminates in expert testimony. It is critical to choose an expert with the necessary technical knowledge and experience. It’s also crucial that the expert can explain technical ideas, forensic techniques, and digital artifacts in simple English. Since jargon and acronyms may be confusing for fact-finders. Finally, even if an expert has a sound analysis, their words are useless if they cannot successfully express it to a court and jury. When choosing an expert, choose someone with whom you can converse. If an expert can’t explain technical information to you in a way that you can grasp.
