摘要： Provided are an apparatus and method for detecting a Dynamic Link Library (DLL) inserted by a malicious code. The method includes collecting first DLL information from an image file of a process before the process is executed; collecting second DLL information loaded into a memory as the process is executed; comparing the first DLL information with the second DLL information to extract information on an explicit DLL; and determining whether the explicit DLL is a DLL inserted by a malicious code or not.

摘要： Provided is a device and method for inspecting software for vulnerabilities which fuzzes the software by function. The device for inspecting software for vulnerabilities includes a target function selecting module for selecting a function of the software for vulnerabilities to be inspected, a comparison file generating module for generating a first file including the selected function and a second file not including the selected function, a binary pattern comparing module for detecting a changed or added binary pattern by comparing binary values of the first file and the second file, a test case generating module for generating at least one test case based on the detected binary pattern, and a vulnerability verifying module for inspecting vulnerabilities based on the at least one test case and generating a vulnerability inspection result. Accordingly, by intensively fuzzing a part of the software which is changed or added according to the function of the software, software vulnerabilities can be found by each function and fuzzing efficiency can be improved.

摘要： A defense method and device against intelligent bots using masqueraded virtual machine information are provided. The method includes performing global hooking on a virtual machine detection request transmitted by a process, determining, on the basis of pre-stored malicious process information, whether or not, the process transmitting the virtual machine detection request corresponds to a malicious process, and when the process is found to correspond to the malicious process as a result of the determination, determining that the process is generated by the intelligent bot, and returning the masqueraded virtual machine information to the process.

摘要： Provided is an apparatus and method for detecting a malicious file that attempts to initiate communication in a mobile terminal without a user's approval. The method of detecting a malicious file in a mobile terminal includes: determining whether a file to be examined is an executable file; when the file is an executable file, examining whether the file is a malicious file that can cause unapproved communication based on at least one predetermined examination condition; and outputting the result of examining whether the file is the malicious file. Accordingly, an attack caused by a new type of malicious code can be coped with.
