Abstract: A computerized method for detecting premium attacks by an attack classification system is described. Based on received analytic information, the attack classification system generates logical representations for different portions of the analytic information represented as a nodal graph. The logical representations include objects, properties, and relationships between the objects and the properties. The attack classification system filters at least one relationship from the relationships and forms a first cluster further filtering the relationships. Being a logical representation of objects, properties and the remaining relationships, the first cluster is analyzed to determine features and introduce the features into the nodal graph.

Abstract: A late load technique deploys a virtualization layer underneath an operating system executing on a node of a network environment to enable the virtualization layer to control the operating system. Binary executable files (binaries) for the virtualization layer may be included in a ring 0 driver loaded in memory of the node with the highest privilege level (e.g., host mode ring 0) needed to control the guest operating system. The ring 0 driver may request allocation of physical memory from the guest operating system for the virtualization layer and thereafter suspend the guest operating system and hardware resources of the node in a deterministic manner. The ring 0 driver may capture architectural states of those resources, which are used to create a virtual machine and virtual devices having initial states that are substantially identical to the states of the operating system and hardware resources at the time of suspension.

Abstract: A computerized technique is provided to analyze a message for malware by determining context information from attributes of the message. The attributes are determined by performing one or more of a static analysis of meta information of the message (e.g., delivery protocol attributes) to generate a first result; a dynamic analysis of an object contained in the message to generate a second result; and, in some embodiments, an emulation of the object to generate a third result. The first result, second result, and third result are correlated in accordance with one or more correlation rules to generate a threat index for the message. The threat index is compared with a predetermined threshold to determine whether the message should be classified as malware and, if so, an alert is generated.
