Methods and systems for maintaining a sandbox for use in malware detection

Abstract

A shadow sandbox is maintained for malware detection. The shadow sandbox is a virtual machine replica of a target computing environment from a protected computing system. The shadow sandbox is maintained through all change events that occur to the target computing environment. The described systems and methods of detecting or preventing malware execution include maintaining a virtual machine replica of a target computing system by monitoring the target computing system for a plurality of possible events, the plurality of possible events including change events and risk events, detecting a change event on the target computing system, and updating the virtual machine based on the detected change event. The described systems and methods detect a risk event on the target computing system, execute the risk event on the virtual machine, and determine whether the risk event is malicious based on observation of execution of the risk event on the virtual machine.
