Problems solved by technology
[0004] The current application detection method is to detect the source code of the App, but it requires a lot of computing and storage resources, and the detection efficiency is low; and when the malicious App code changes or uses code obfuscation, packing and other technologies, it can be easily detected. Bypass detection of
Therefore, the current detection method for malicious App consumes a lot of resources, and the accuracy of the detection result is low.

The invention discloses a malicious application detection method and device and a storage medium. The application detection method comprises the steps of obtaining the initial information of an operating system; acquiring the running information of the operating system; comparing the legal application information with the to-be-detected application information, or comparing the configuration information in the initial state with the configuration information in the running state to obtain a comparison result; and under the condition that the comparison results are different, determining that the to-be-detected application on the operating system is a malicious application. According to the method, the configuration information of the operating system in the initial state and the configuration information of the operating system in the running state are compared, and the legal application information of the operating system is compared with the to-be-detected application information, so that the security of the to-be-detected application is detected, the malicious level of the to-be-detected application is evaluated, a large amount of computing and storage resources can be saved, and the detection efficiency is improved. Malicious application detection is still effective when codes are changed or technologies such as code obfuscation and encasing are adopted, and the accuracy of a detection result is improved.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to a detection method, device and storage medium for malicious applications. Background technique [0002] Application (Application, App) is a computer program for completing one or more specific tasks. An operating system based on the Linux kernel, such as an Android (Android) system, is mainly used in mobile terminal devices. Due to the open source and rich scalability of the operating system code based on the Linux kernel, the functions of the App developed based on the Linux kernel operating system are becoming more and more diverse, which greatly meets the various needs of people in daily life. [0003] However, the black industry, which is attached to the terminal system with a huge number of users and conducts fraud, fee deduction, and mining through malicious apps, is also developing rapidly. The black industry has a major impact on the data security of users. ...
