Problems solved by technology

However, once it is impossible to distinguish official or third-party apps, it is impossible to make an effective judgment
[0012] (2) Large error in dynamic analysis
However, the disadvantage of this method is that the detection results are not accurate enough and the error is large

Abstract

The invention provides an Android malicious software detection method and system based on dynamic monitoring. The method comprises the following steps: S1, establishing a rule library of various information of a mobile terminal; S2, after a target function address is looked up, replacing the target function address with a function address comprising monitoring codes; S3, when an application of the mobile terminal is started, monitoring the behavior of the application; S4, judging whether or not the behavior of the application is a sensitive behavior executed by Android malicious software. According to the Android malicious software detection method and system based on dynamic monitoring, the aim of effectively monitoring malicious software is fulfilled by simulating running of third-party application software, monitoring sensitive data streams and analyzing sensitive data leakage of application software and making a safety alarm when the sensitive data is tampered.

Description

technical field [0001] The invention relates to a detection method of malicious software, in particular to a detection method and system of Android malicious software based on dynamic monitoring. Background technique [0002] Android is an open-source mobile device operating system based on Linux, which is mainly used in smartphones and tablet computers. However, the openness of its platform makes Android a large number of malware, and it has become the hardest hit area for mobile terminal security. On the one hand, mobile phone manufacturers can flexibly modify and customize mobile phone operating systems for their own brands, and the handling of system security by different manufacturers is inconsistent, allowing malware to take advantage of it; on the other hand, its openness also It has increased the number of people studying Android malware, and even spawned some malware developers. [0003] With the popularity of smart phones and tablet computers, malicious codes targ...
