Abstract
Reverse-engineering malware code is a difficult task, usually full of the traps put by the malware writers. Since the quality of defense softwares depends largely on the analysis of the malware, it becomes crucial to help the software investigators with automatic tools. We describe and present a tool which synchronizes two related binary programs. Our tool finds some common machine instructions between two programs and may display the correspondence instruction by instruction in IDA. Experiments were performed on many malware such as stuxnet, duqu, sality or waledac. We have rediscovered some of the links between duqu and stuxnet, and we point out OpenSSL's use within waledac.

<front><div type="abstract" xml:lang="en">Reverse-engineering malware code is a difficult task, usually full of the traps put by the malware writers. Since the quality of defense softwares depends largely on the analysis of the malware, it becomes crucial to help the software investigators with automatic tools. We describe and present a tool which synchronizes two related binary programs. Our tool finds some common machine instructions between two programs and may display the correspondence instruction by instruction in IDA. Experiments were performed on many malware such as stuxnet, duqu, sality or waledac. We have rediscovered some of the links between duqu and stuxnet, and we point out OpenSSL's use within waledac.</div>

<abstract xml:lang="en">Reverse-engineering malware code is a difficult task, usually full of the traps put by the malware writers. Since the quality of defense softwares depends largely on the analysis of the malware, it becomes crucial to help the software investigators with automatic tools. We describe and present a tool which synchronizes two related binary programs. Our tool finds some common machine instructions between two programs and may display the correspondence instruction by instruction in IDA. Experiments were performed on many malware such as stuxnet, duqu, sality or waledac. We have rediscovered some of the links between duqu and stuxnet, and we point out OpenSSL's use within waledac.</abstract>
<abstract xml:lang="fr">La rétroconception de programmes malveillants est une tâche difficile, parsemée des embûches préparées par les développeurs du malware. La qualité des logiciels de défense dépendant grandement de l'analyse faite du malware, il est nécessaire de fournir aux analystes des outils automatiques. Nous décrivons ici un outil qui synchronise deux programmes binaires ayant des similarités. Notre outil trouve des instructions assembleur communes et affiche les correspondances dans IDA. Des expériences ont été réalisées sur plusieurs malware tels Stuxnet, Duqu, Sality ou Waledac. Nous avons retrouvé certains liens entre Duqu et Stuxnet ainsi que l'utilisation que Waledac fait d'OpenSSL.</abstract>
