I am new to the Malware Analysis field. I installed Cuckoo and VirtualBox and did all the necessary configuration that is required. However the problem I am facing is that when I run cuckoo after submitting an exe file, I have to run the agent.py file manually in VirtualBox. I have pasted the agent.py file in the startup folder of the Windows 7(in VirtualBox), also made a .bat file which runs the agent.py file and placed it in the startup folder. What may be the problem that the agent.py is not starting automatically? Can anyone help me regarding this?
