It is always assumed that if the attackers can achieve their goal by exploiting a vulnerability once, they won’t exploit it twice. This assumption shapes our view of what attacks look like, and affects the design of many security systems. In this work, we propose the swarm attack, in which the attacker deliberately exploits the same vulnerability multiple times, each intended to carry out only ...

Code injection attacks against server and client applications have become the primary method of malware spreading. A promising approach for the detection of previously unknown code injection attacks at the network level, irrespective of the particular exploitation method used or the vulnerability being exploited, is to identify the malicious code that is part of the attack vector, also known as...

Enterprise Resource Planning (ERP) Systems are notoriously difficult for users to operate. We present a framework that consists of a data model and algorithms that serve as a foundation for implementing design principles presented in an earlier paper for improving ERP usability. The framework addresses the need for providing user, task and process context of each system-user interaction. It is ...

Remote code injection attacks against network services remain one of the most effective and widely used exploitation methods for malware propagation. In this paper, we present a study of more than 1.2 million polymorphic code injection attacks targeting production systems, captured using network-level emulation. We focus on the analysis of the structure and operation of the attack code, as well...

Subject review Security attacks are becoming a standard part of the Internet and their frequency is constantly increasing. Therefore, an efficient way to research and investigate attacks is needed. Studying attacks needs to be coupled with security evaluation of currently deployed systems that are affected by them. The security evaluation and research process needs to be completed quickly to co...

This paper discusses the production of visually appealing computer-generated images, through the emulation of human drawing techniques and artificial evolution. Employing a database of line drawn objects from user-input, the Darwinian process of evolution produces original compositions with increasing levels of user sat-

primary hypokalemic periodic paralysis is a familial channelopathy inherited as an autosomal dominant trait. the first attack of paralysis may be evolved at any age, but has been reported to be most common in the second decade, so that some authorities believe that an episodic weakness beginning after age 25 is almost never due to primary periodic paralysis. in this retrospective study, we revi...

Due to the growth of both design complexity and the number of gates per pin, functional debugging has emerged as a critical step in the development of a system-on-chip (SOC). Traditional approaches, such as system emulation and simulation, are becoming increasingly inadequate to address the system debugging needs. Design simulation is two to ten orders of magnitude slower than emulation and, th...
