Original Abstract

The register realignment is a method of binary obfuscation and it is used by malware writers. The paper introduces the method how register realignment can be recognized by analysis based on the scattered context grammars. Such an analysis includes exploration of bytes affected by realignment, finding new valid values for them, building the scattered context grammar and parse an obfuscated code by this grammar. The created grammar has LL property - an ability for parsing by this type of grammar.
