I'm pleased to announce the availability of a new paper: Comparing binaries with graph isomorphisms. http://razor.bindview.com/publish/papers/comparing-binaries.html The paper presents a method and algorithms for finding differences between two versions of a binary executable file, based on graph isomorphisms. One possible application is to discover the differences in a security patch, and a couple examples in that vein are shown. A brief comparison is also made to Halvar Flake's function signatures approach (as I understand it). The tool implementing the technique is not being made available at this time, but will likely be released later this year. -- Todd Sabin <tsabin@optonline.net> BindView RAZOR Team <tsabin@razor.bindview.com>
