Digital Forensics Security Analysis on iOS Devices

With the rapid development of the Internet era, cell phones play an essential and indispensable role in nowadays life. Smartphones have profoundly influenced our social relationships and our daily lives. Generally speaking, the most common tools we hear about in our daily lives are QQ, WeChat, and other Internet communication services that allow users to send text messages, pictures, and documents, providing a more convenient and faster medium for people to communicate and chat. The popularity and convenience of mobile technology have changed people's habits of communication. People no longer need to rely on computers to communicate, and computers cannot communicate anytime and anywhere. In the kernel of Linux and Windows, as long as the Message Hooker will install, it can monitor the messages of other programs, including WeChat and QQ, in this research. We can provide relevant law enforcement officers with effective evidence collection so that criminals will not be able to hide. The suspects often delete their WeChat or QQ records after committing the crime. It impossible for our law enforcement agencies to obtain evidence directly from the cell phone and the crime facts. Our research hopes to use some technology to help law enforcement units effectively obtain strong evidence in the iPhone not to hide the crime facts.
