Abstract: A device may receive a trigger to determine whether a malicious file is operating on a client device. The device may determine a network activity profile associated with the malicious file based on receiving the trigger to determine whether the malicious file is operating on the client device. The network activity profile may include information regarding network activity associated with the malicious file when the malicious file is executed in a testing environment. The device may monitor network activity associated with the client device. The device may determine that the network activity associated with the client device matches the network activity profile associated with the malicious file based on monitoring the network activity associated with the client device. The device may provide information indicating that the network activity associated with the client device matches the network activity profile associated with the malicious file.

Abstract: In one example, a server executes a virtual router configured to receive an inner packet output by a virtual machine associated with a virtual network. The virtual router is further configured to offload, to a physical network interface card of the server that executes the virtual router, segmentation of the inner packet into a plurality of outbound tunnel packets each having a tunnel header for output by the physical network interface card to a physical network underlying the virtual network.
