Abstract

In this paper we present a novel approach to detection of metamorphic computer viruses by using proving program equivalence based on program transformation technique known as supercompilation [7]. Proving program equivalence is an undecidable problem in the general case; however, in specific cases we may find decidable or semi-decidable procedures that can prove that a sub-class of programs are equivalent. This is of relevance for detecting metamorphic computer viruses, which use a variety of semantics-preserving, syntax-mutating methods for code obfuscation. The main purpose of this obfuscation is to avoid detection by signature scanning. An important factor here is that semantics is preserved; therefore, if we can prove using some procedure that two different programs are equivalent, then in principle we can detect metamorphic computer viruses using this procedure.
