Survey about CWsandbox tool which utilise for dynamic malware analysis - Research Paper vitrineGeneral Sandbox Architecture A sandbox is deployed to secure a computer corpse from external attacks that are attempted through malware (malicious program). According to Hoopes (2009), the approaches used are both to block the critical accessibility of a malware or to introduce a simulated environment with completely virtual computing resources standardized CPU, file system and the memory. This virtual environment enables the program to get executed in a completely isolated environment which is disconnected from the real exploit environment within which it resides. The of import idea is to monitor the accessibility of program (under observation) to system resources. This way the system can be brought back into the safe area after complete behavioral analysis of the suspected program. The fringe benefit of this approach is the usage of a lighter security protocol for the underlying s ystem that improves its working efficiency. The behavioral analysis keeps the execution environment intact. This gives it an edge over instruction level analysis (basic everyy done victimization debuggers or dis-assemblers). CWSandbox architecture and surgical process CW sandbox is one the sandbox applications that are in use. Every sandbox application has its own mechanism to secure the computer system environment. CWSandbox comprise of deuce executable files namely cwsandbox.exe and cwmonitor.dll. The former is the central application that initiates the malware and manages the complete process of analysis. The latter on the other hand is a DLL (Dynamic Link Library). This library is introduced into all processes in the malware that are under observation. This way the malware is actually executed and being interacted by the sandbox along with its own execution. The function of the DLL file is to catch distributively API critical call from malware and to inform the central applica tion (cwsandbox.exe) about it. The sandbox (main application) then takes some time to analyze the call in order to either delegate the control to the required API (in case of safe conclusion) or to answer the call with a virtual error message (in opposite case). Along with the charge an eye on every malware call, the DLL also makes it certain that the sandbox is kept informed about other malware activities like injecting a code into an already implementation process or creating a child process. In both cases the DLL is instantiated again to be injected into the child process or the already running process. Figure 1.0 below, elaborates the set forth functioning. The CWSandbox uses the native execution environment unlike other sandbox schemes. This in turn reduces the delay caused by the analysis mechanism. Enormous confabulation exists between the main application (executable) and planted instances of DLLs. Each notification call from a DLL to sandbox contains a lot of informatio n that requires a formal and reliable mechanism of communication between processes. In order to fulfill this requirement the sandbox is usually equipped with high efficiency IPC (Inter Process Communication) mechanism. Figure 1.0.
