There are three methods used for the data extraction from the IOS devices. But we could calculate the hash value of the extracted data through logical extraction or of the image file extracted through physical extraction. As previously mentioned it is almost impossible to interact with mobile devices without altering them. MD5 or SHA are widely used algorithms to calculate the Hash values of the evidence.

It includes details like serial no, case no, locker no, Chain of Custody – Chain of custody is the document to maintain each record of the Digital evidence from the collection to presentation.There are several ways that could be followed according to the scenario,.So, the first step should be to isolate the mobile device from the network. It is possible that attackers could remotely wipe data or any new activity could override the existing data.For mobile forensics below steps are good practices to follow: If it is very important to maintain evidence integrity throughout the investigation. Preservation of evidence is a very crucial step in digital forensics. Search for the SIM package and if any cables are located around.If it is power on then, check the battery status, network status.
It is good practice to take a picture using the camera of the location and mobile phone before starting any progress.

With these challenges in mobile forensics, syncing mobiles phone to a computer using software becomes easy. Each case or investigation of the new model needs to be considered differently and requires following steps that could be different and unique to the case. The ratio of new models designed and launched is very high which makes it very difficult to follow similar procedures. The mobile phone generally belongs to a single person so analysis of it could reveal lots of personal information.ĭue to the rapid growth, it also introduced challenges. Due to the exponential growth of the mobile market, the importance of mobile forensics has also increased. Mobile forensics is a field of digital forensics which is focused on mobile devices which are growing very fast. Introduction to the forensic processes focused towards mobile forensics, extracting logical and physical data from the IOS devices, IOS file system and storage analysis, analysis of logical data, data from the iTunes and iCloud back up, Wi-Fi and GPS data. This paper could be divided into the following sections. There are well-defined procedures to extract and analyze data from IOS devices which are included in this paper. From the forensics perspective, such devices could present lots of useful artifacts during the investigation. IOS devices provide larger storage space that could store emails, browsing histories, chat histories, Wi-Fi data and GPS data and more. The latest smartphones or tablets can perform ideally most of the tasks which could be performed on a laptop or personal computer. Apple operating system (IOS) devices started growing popular in the mobile world. iPhone and iPad are the game-changer products launched by Apple. Oxygen Forensic® Detective is distributed in a USB dongle and is valid for a single user.Day by day, smartphones and tablets are becoming ever more popular, and as a result, the technology used in development to add new features or improve the security of such devices is advancing too fast. By using the integrated industry-leading analytical tools to find social connections, build timelines, and categorize images, law enforcement, corporate investigators and other authorized personnel can help make this world a safer place. The cutting edge and innovative technologies deployed in Oxygen Forensic® Detective include, but are not limited to, bypassing screen locks, locating passwords to encrypted backups, extracting and parsing data from secure applications and uncovering deleted data.įurthermore, multiple extractions can be investigated in a single interface to gain a complete picture of the data.
Oxygen Forensic® Detective can also find and extract a vast range of artifacts, system files as well as credentials from Windows, macOS, and Linux machines. Oxygen Forensic® Detective is an all-in-one forensic software platform built to extract, decode, and analyze data from multiple digital sources: mobile and IoT devices, device backups, UICC and media cards, drones, and cloud services.
