Detecting Undetectable Computer Viruses
Signature-based detection relies on patterns present in viruses and provides a relatively simple and efficient method for detecting known viruses. At present, most anti-virus systems rely primarily on signature detection. Metamorphic viruses are one of the most difficult types of viruses to detect. Such viruses change their internal structure, which provides an effective means of evading signat...
متن کاملDetecting Metamorphic Viruses Using Profile Hidden Markov Models
Detecting Metamorphic Viruses using Profile Hidden Markov Models By Srilatha Attaluri Metamorphic computer viruses “mutate” by changing their structure every time they propagate. Unlike other viruses, they use code obfuscation techniques on the body of the virus and do not exhibit a common signature. With the advent of construction kits, it is easy to generate various metamorphic strains of a v...
متن کاملA highly metamorphic virus generator
Abstract: Metamorphic viruses modify their code to produce viral copies that are syntactically different from their parents. The viral copies have the same functionality as the parent but typically have no common signature. This makes signature-based virus scanners ineffective for detecting metamorphic viruses. But machine learning tool such as Hidden Markov Models (HMMs) have proven effective ...
متن کاملAnalysis and Detection of Metamorphic Computer Viruses
comparison between our approach and commercial virus scanners. I would also like to thank my friends and schoolmates for their technical and emotional support. I want to thank Yue Wang for performing the virus scanning, and Peter Hey for repairing my hard disk after it crashed at the most critical moment. Finally I want to thank my family for their understanding and support throughout my five y...
متن کاملPairwise Alignment of Metamorphic Computer Viruses
Computer viruses and other forms of malware pose a threat to virtually any software system. A computer virus is a piece of software which takes advantage of known weaknesses in a software system, and usually has the ability to deliver a malicious payload. A common technique that virus writers use to avoid detection is to enable the virus to change itself by having some kind of self-modifying co...
