Abstract Metamorphic malware —(More)
A design space is presented for metamorphic malware. Metamorphic malware is the class of malicious self-replicating programs that are able to transform their own code when replicating. The raison d'etre for metamorphism is to evade recognition by malware scanners; the transformations are meant to defeat analysis and decrease the number of constant patterns(More)
This paper takes an in-depth look into the attack strategies of recent rootkits and analyses what has worked for them. In doing so it highlights some of the profi table attack methodologies from the perspective of kernel rootkits. The discussion in this paper about prediction of the future of stealth attacks is derived from our analysis of multiple rootkits(More)
A malware mutation engine is able to transform a malicious program to create a different version of the program. Such mutation engines are used at distribution sites or in self-propagating malware in order to create variation in the distributed programs. Program normalization is a way to remove variety introduced by mutation engines, and can thus simplify(More)

The continuous development of esthetically acceptable adhesive restorative material has made a variety of tooth-colored materials available for clinical use. The advent of visible light polymerizing resin and the use of finer filler particles permit resin composites to be polished to higher degree. The effect of polishing systems on surface finish has been(More)
