15. The non-transitory storage medium of claim 12 , wherein the one or more software modules, upon execution, determining whether the object includes one or more characteristics associated with a malicious attack by at least performing an heuristic analysis that analyzes the object using metadata or attributes of the object to determine whether a portion of the object has characteristics that suggest the object is associated with a malicious attack.
16. The non-transitory storage medium of claim 12 , wherein the one or more software modules, upon execution, determining whether the object includes one or more characteristics associated with a malicious attack based on operations performed by at least one virtual machine that is configured to process the object.
17. The non-transitory storage medium of claim 12 , wherein the one or more characteristics comprise a source address that is associated with a known exploit.
