1. A system in communication with a communication network, the system comprising: one or more virtual computing systems; and a controller in communication with the one or more virtual computing systems, the controller to (i) configure a software profile of a first virtual computing system of the one or more virtual computing systems to correspond to a software profile of a network device of the communication network, (ii) initiate operations of the first virtual computing system of the one or more virtual computing systems associated with content received over the communication network, (iii) monitor for behaviors of the first virtual computing system that include an attempted emission of a plurality of packets from the first virtual computing system, (iv) determine whether a monitored behavior of the monitored behaviors of the first virtual computing system corresponds to an anomalous behavior based on the packets involved in the attempted emission, and (v) determine an identifier characterizing at least the anomalous behavior including the attempted emission that represents an attack involving the content, the content being deemed malicious content; and a malicious content blocking system to receive the identifier and use the identifier to block propagation of other content corresponding to the content involved in the attack.
