| In recent years, with Chinese the rapid development of Mobile Internet, growth and spread ofthe malicious code in smartphone has became more rapid pace. The malicious mobile code oftencause the direct or indirect economic losses.The malicious code directly related to the developmentof Chinese Mobile Internet and the benefit for Smartphone users. Smartphone is more closer lifethan PC. Android is the most popular smart terminal operating system now, so the analysis andstudyofmalwaredetectiontechnology onAndroid isessential andurgent.This paper research the current security mechanisms on the Android, pointed out theinadequacies of the security mechanisms and the security threats of the Android. This article alsoanalyze some specific malicious behavior in Android malware, and list a number of Androidmalware. Besides this paper analyze some common methods which detect malware on theAndroid, anddiscussed thedisadvantageandadvantageofthesemethods.Based on the study of a variety of Android malware detection method, and compare theadvantage and disadvantage of these detection methods, this paper design an automatic detectionsystem to detect malware. The system mainly to detect the stealing privacy information from theSmartphone. The detection system is divided into the Web site, static sandbox, dynamic sandboxand multi-AV detection system. The Web site is response for the interaction with the customer, theother part is response for detecting the Android application. Static sandbox apply reverse analysisto find the sensitive API calls in applications and data flow analysis to identify malicious behaviorof the application. Dynamic sandbox is supplement of the static sandbox. Dynamic sandbox installapplications on the Android virtual machine and imitate the user daily operations.The systemrecord application behavior to identify malicious behavior of the application. Experimental showthatthisdetection systemreallywork.There are three work in this paper.1)The first work is research of the Android securitymechanisms.2)The second work is research of the malicious behavior in Android malware.3)Thethird work is design the Android automatic detection system.4)The forth work is make automaticdetectionsystem cometure, and run thesystem toexaminesystem. |
