The invention provides a mobile terminal forensics obtaining method and device based on a dynamic loading technology, and the method comprises the steps of dividing digital forensics software installed in a mobile terminal into a first application program and a second application program; installing the first application program in the mobile terminal after digital forensics starts, installing a second application program through the first application program, loading the second application program based on a dynamic loading technology, deleting the second application program after the secondapplication program is loaded, and finally calling the loaded second application program through the first application program to perform digital forensics on the mobile terminal. According to the invention, the application program can be dynamically loaded in the installed and operated application, and the core code of the application program is operated and used, so that the core code of the application program can be used without falling to the ground, and the aim of protecting the core code of the application program is fulfilled.
Description
technical field [0001] The invention relates to the technical field of digital forensics, in particular to a digital forensics method for mobile terminals based on dynamic loading technology and a digital forensics device for mobile terminals based on dynamic loading technology. Background technique [0002] With the continuous update and iteration of the Android version of mobile phones, security is increasingly valued by all walks of life. Especially in the current field of judicial evidence collection, it is increasingly difficult to ROOT mobile phones in the collection technology of mobile phone data of suspects, and the cost of obtaining evidence through mobile phone ROOT is increasing. In the target mobile phone to realize the collection of mobile phone data, however, the APP installed in this technology is easy to be reversed and analyzed, resulting in the leakage of the source code. Contents of the invention [0003] The present invention aims to solve one of the ...
