As one of the most important brands of smart phones, Apple's mobile phone market share in China exceeds 20c/o. In view of the uniqueness of the iOS operating system, the data extraction and forensics of Apple's mobile phones have always been the focus of industry research and attention. The changes in hardware and software of different versions of Apple's mobile phones will also have a direct impact on mobile phone forensics.
iPhone7 is on the market, many details change and change
On September 16th, iPhone7 mobile phones were officially launched in 28 countries and regions including China. The market response was very strong! Compared with previous versions, iPhone7 has undergone major changes in appearance, configuration and operating system.
The first is the appearance, the iPhone7 screen size remains at 4.7/5.5 inch combination, the antenna becomes a one-size-fit design; the new matte black and bright black color is added, the camera is more convex; the 3.5mm headphone interface design is cancelled, the camera is added. Optical anti-shake function.
Secondly, the iPhone7 is equipped with a quad-core A10 Fusion processor and 2GB of RAM; the storage capacity is 16GB, starting from 32GB, and it is available in 32GB, 128GB and 256GB versions.
The third is the operating system, and the iPhone 7 uses the latest iOS10 operating system. iOS10 allows users to delete some system native applications, such as memos, calculators, maps, iBooks, etc.; iMessage has a separate app store to download emoticons and plug-ins; Apple Map can directly complete the call, book restaurant, etc. Jump; open the data interface, can realize caller identification function through third-party applications.
iPhone7 changes, increasing the difficulty of mobile phone forensics
These changes in the iPhone 7 will help to further enhance the user experience, but bring new challenges to mobile phone forensics.
According to the research of researchers in the key laboratory of Sichuan Province, the impact of iPhone 7 changes on mobile phone data extraction is mainly reflected in the following aspects:
Key Laboratory of Data Recovery in Sichuan Province
(1) Data storage structure changes. After the introduction of the iOS10 operating system, the iPhone 7 data has changed in the storage structure, increasing the difficulty of data extraction of mobile phones.
(2) The storage capacity becomes large. The maximum storage capacity of the iPhone 7 can reach 256 GB. The larger the storage space, the more data needs to be extracted when the mobile phone is forensic, and the data processing capability, speed and other hardware performance of the forensic equipment are higher.
(3) Delete data recovery. iPhone data recovery has always been an industry problem. The iPhone 7 part of the system's native applications, such as memos, maps, iBooks, etc. can be directly deleted, further increasing the difficulty of deleting data recovery.
Responding to challenges, Chinese companies take the lead in supporting iPhone 7 mobile phone forensics
For mobile phone forensics, major domestic and foreign manufacturers include Israel's Cellebrite, the US's logicube, Sweden's MicroSystemation, Xiamen Meiyabo, Sichuan's efficiency source, and Shanghai Panshi. Based on the challenges brought about by the changes in the iPhone7, these mobile phone forensics vendors have already conducted research.
