Malware signature generation using locality sensitive hashing

Security threats due to malicious executable are getting more serious. A lot of researchers are interested in combating malware attacks. In contrast, malicious users aim to increase the usage of polymorphism and metamorphism malware in order to increase the analysis cost and prevent being identified by anti-malware tools. Due to the intuitive similarity between different polymorphisms of a malware family, clustering is an effective approach to deal with this problem. Clustering accordingly is able to reduce the number of signatures. Therefore, we have leveraged the Suffix tree structure and Locality Sensitive Hashing (LSH) to linearly cluster malicious programs and to reduce the number of signatures significantly
