Abstract

The invention discloses a malicious Android application program detection method, system and device. The method comprises the following steps of: imitating the execution of Android application programs by a server; matching sensitive characteristic information and sensitive date of system functions called by the Android application programs with sensitive characteristic information stored in a rule base, and marking variables of the matched system functions as sensitive data; and matching the functions containing the sensitive data with characteristic information of malicious acts stored in a malicious act detection rule base, and marking parameters of the matched functions as malicious acts. According to the technical scheme, the method, the system and the device can be used for detecting malicious Android application programs on the premise that manual analysis of characteristic codes is not relied on, thus alleviating the workload of technicians.

Description

technical field [0001] The invention relates to malicious application program detection technology, in particular to a method, system and device for detecting an Android (Android) malicious application program. Background technique [0002] As an open source smartphone operating system, the Android system has attracted a large number of application program developers. Since there is a large amount of user privacy information stored in smart phones, a large number of malicious applications are attracted to the application program market to steal users' privacy information; The maliciousness of the application program is screened, so a large amount of user privacy information is leaked, and the user of the application program suffers a great loss. [0003] Android malicious applications refer to software that is installed and run on the user's computer or other terminals without explicitly prompting the user or without the user's permission, violating the user's legitimate ri...
