Method for the automatic generation of malware signatures from computer files. A common function library (CFL) created, wherein the CFL contains any functions identified as a part of the standard computer language used to write computer files which are known as not containing malware. The functions of a computer file which does contain a malware are extracted and the CFL is updated with any new common functions if necessary, such that the remaining functions are all considered as candidates for generating the malware signature. The remaining functions are divided into clusters according to their location in the file and the optimal cluster for generating the malware signature is determined. One or more of the functions in the optimal cluster is selected randomly, as the malware signature.

Automatic extraction of signatures for malware

The invention is a comprehensive conceptual and computational architecture that enables monitoring accumulated time-oriented data using knowledge related to the operation of elements of a computer network and deriving temporal abstractions from the accumulated data and the knowledge in order to identify electronic threat patterns and create alerts. The architecture of the invention supports two main modes of operation:
