Patent attributes
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.
