PyBox - A Python Sandbox

The application of dynamic malware analysis in order to automate the monitoring of malware behavior has become increasingly important. For this purpose, so-called sandboxes are used. They provide the functionality to execute malware in a secure, controlled environment and observe its activities during runtime. While a variety of sandbox software, such as the GFI Sandbox (formerly CWSandbox) or the Joe Sandbox, is available, most solutions are closed-source. We present the design, implementation and evaluation of PyBox, a flexible and open-source sandbox written in Python. The application of a Python based analysis environment offers the opportunity of performing malware analyses on various operating systems as Python is available for almost every existing platform.
