Forensic analysis of the Windows registry in memory

Abstract

This paper describes the structure of the Windows registry as it is stored in physical memory. We present tools and techniques that can be used to extract this data directly from memory dumps. We also provide guidelines to aid investigators and experimentally demonstrate the value of our techniques. Finally, we describe a compelling attack that modifies the cached version of the registry without altering the on-disk version. While this attack would be undetectable with conventional on-disk registry analysis techniques, we demonstrate that such malicious modifications are easily detectable by examining memory.
