Abstract


With the popularity of computers and networks, viruses, Trojans and spyware and other malicious software hazardous to continuously improve the sweep range continues to expand. In order to deal with this crisis, the anti-virus software development is very rapid, successfully resisted a variety of malicious attacks. However, the existing anti-virus software, there are also many problems. First of all, most of the existing anti-virus software based on the virus database and signature mechanisms against new malicious software is not obvious. Secondly, these anti-virus software is simply determined whether a software virus, and the lack of its functions performed Note. This makes the virus the analysts difficult to quickly and accurately locate the position of the malicious code. Analysts urgent need for a way to label the tools of the program behavior, it can distinguish between benign and malicious behavior, reasonable performance result of malicious behavior detection, enables analysts to an overall assessment of the degree of suspicion and danger of the program. In-depth study the the decompile technical and labeling technology based on the proposed labeling scheme of malicious behavior based on decompilation technology - dual-space multi-level labeling schemes. In-depth analysis of SVG (Scalable Vector Graphics) technology basis, suspicious behavior SVG-based graphical annotations, and elaborates on the specific implementation process, constitute a dual-space multi-level tagging system space. Structure information for based on decompilation malicious behavior on the basis of this article in the analysis of the technical characteristics and application of the Extensible Markup Language XML (eXtensible Markup | Language) to describe the complexity of the problem, design the suspicious behavior of XML-based description language SBDL (Suspicious Behaviors Description Language), a standardized description method for malicious behavior, constitute the second space of the double-space multi-level tagging system. Project team designed and implemented a prototype system Radux (Reverse Analysis for Detecting Unsafe eXecutables) labeling schemes designed in this paper, to achieve multi-level annotation of malicious behavior detection algorithm, the system has passed the two test units test and in some units to install and use, and achieved good results, which also verified the programs and algorithms of this paper is feasible and effective.
