Embodiment Construction
[0026] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0027] The so library file reinforcement identification method described in the preferred embodiment of the present invention, such as figure 1 As shown, the so library file reinforcement identification method includes the following steps:
[0028] Step S10, when the so library file is reinforced and identified, read the section name list of the so library file, compare the section name list with the conventional Section library, and determine whether the number of conventional Sections in the so library file is less than the preset amount;
[0029] Step S20, when no, view the list of ...

The invention discloses a so library file reinforcement recognition method, an intelligent terminal and a storage medium. The method comprises the steps of reading a node name list of a so library file and comparing the node name list with a conventional Section library when reinforcing recognition is performed on the so library file, and judging whether the number of conventional Sections in theso library file is smaller than a preset number or not; if not, checking the dynamic link symbol list, and judging whether the dynamic link symbol list contains a shell entry of a preset feature codeor not; if not, checking a function name list of the so library file, and judging whether the function name list is subjected to function name confusion or not; if not, a feature library is generated,feature matching is conducted on the so library file and the feature library, whether matching succeeds or not is judged, if yes, the so library file is reinforced, If not, the so library file is notreinforced. According to the method, whether the so library file is reinforced or not is identified in various modes, so that the recognition accuracy can be greatly improved.
Description
technical field [0001] The present invention relates to the field of computer application technology, in particular to a so library file reinforcement identification method, an intelligent terminal and a storage medium. Background technique [0002] The SO file format is the ELF file format (the ELF file format is a format file for binary files, executable files, object code, shared libraries, and core dumps, and is also the main executable file format for Linux). A unified format for executable files, shared library files, and object files. According to different ways of looking at ELF files, ELF files can be divided into link view and loading view; link view is the linker looking at static ELF files from the perspective of link; looking at ELF files from link view, ELF files are composed of multiple sections, different The section has different names and permissions; and the loading view is the dynamic ELF file viewed by the operating system from the perspective of loadin...
