Techniques for detecting exfiltration content are described herein. According to one embodiment, a malicious content suspect is executed and a packet inspection of outbound network traffic is performed by a packet inspector running within the virtual machine. Occurring before the outbound network traffic leaving the virtual machine, the packet inspector determines whether a portion of outbound network traffic matches one or more portions of predetermined network traffic patterns or signatures. If so, a determination is made whether the outbound network traffic includes at least one environmental property of the virtual machine that is unique or almost unique to the virtual machine. If so, migration of the outbound network traffic outside of the virtual machine is precluded and an alert is transmitted. The alert includes the malicious content suspect that is attempting to perform an exfiltration of data.

System and method for detecting exfiltration content

System and method for detecting malicious activity based on at least one environmental property

Techniques for detecting exfiltration content are described herein. According to one embodiment, a malicious content suspect is executed within a virtual machine that simulates a target operating environment associated with the malicious content suspect. A packet inspection is performed on outbound network traffic initiated by the malicious content suspect to determine whether the outbound network traffic matches a predetermined network traffic pattern. An alert is generated indicating that the malicious content suspect should be declared as malicious, in response to determining that the outbound network traffic matches the predetermined network traffic pattern.
