Abstract: A method and an apparatus for analyzing the malware software within a non-executable file which uses the virtual environment use the object program having the weak point in the virtual environment are provided to analyze the malware included in the non-executable file safely. A program execution part(114) outputs register value of an object program by loading non-executable file analyzed in an object program. A program run analysis part(122) analyzes the outputted register value. In case the register value indicates a domain except a normal code domain, the program run analysis part stores log information about the operation of the object program in the log information database(124). A malware analyze part(126) extracts and analyzes malware included in the non-executable file based on log information. When the outputted register value begins to indicate domain except the normal code area, the program run analysis part begins to store the log information.

Abstract: PURPOSE: An apparatus for detecting a modulated URL by HTTP header analysis and a method thereof are provided to remove a threat connected to a malicious site without the consent of a user by checking whether a corresponding URL is modulated or not before connecting the URL which is possibly modulated on a webpage of a connected website. CONSTITUTION: An apparatus for detecting modulated URL includes a control unit(10), a URL information collecting unit(40), a URL HTTP header analyzing unit(50), and a URL modulation checking unit(60). The control unit controls the operation of each unit of the apparatus for detecting the modulated URL. The URL information collecting unit collects URL information linked with a webpage selected by a user on a connected website if the user terminal executes a web browser and connects to the website of which URL is inputted by a user. The URL HTTP header analyzing unit analyzes HTTP header information from collected URL information if the URL information is collected by the URL information collecting unit. The URL modulation checking unit determines a corresponding URL if retransmission information from the corresponding URL to different URL does not exist in a HTTP header as a result of the HTTP header information analysis of the URL HTTP header analyzing unit. [Reference numerals] (10) Control unit; (20) Input unit; (30) Output unit; (40) URL information collecting unit; (50) URL HTTP header analyzing unit; (60) URL modulation checking unit

Abstract: A DCE RPC(Distributed Computing Environment Remote Procedure Call) object fuzzing system and method are provided to analyze an idl file to acquire necessary information in a DCE RPC object fuzzing operation and construct an RPC based access mechanism by using the information to reduce the cost and time required for system fuzzing. A DCE RPC object fuzzing system includes a file manager, a random data generator, an RPC packet creator, and a packet injector. The file manager parses and analyzes a file having information including an idl file and a named pipe file with respect to an object of fuzzing to acquire necessary information. The random data generator generates a random number by using a system clock signal as a factor. The RPC packet creator constructs a protocol used for RPC communication for each function and creates an RPC packet for RPC communication. The packet injector injects the necessary information and the random number into the generated RPC packet and transmits the RPC packet to the object of fuzzing.
