Memory Forensics

Written by DFMag


Memory Forensics

Haider M. al-Khateeb recovers user credentials from Windows memory dumps.

Mandatory key disclosure laws are used to force a suspect to surrender passwords and cryptographic keys to unlock accounts or scrambled data to authorities. In the UK, this is maintained through the Regulation of Investigatory Powers Act 2000 (RIPA) but a technical investigation to bypass the authentication challenge is needed when an individual refuses to cooperate. Further, user credentials can objectively establish links to end-users of the system. This article continues the work published in Issue 19 of the Digital Forensics Magazine but this time we focus more on analysis methods. Memory dump files contain a real representation of the machine-state at the time of the memory dump; they can be used to recover user-related data such as usernames, passwords and encryption key-files relying on virtual addresses and/or content analysis. We examine and demonstrate the methods available to extract such data from a variety of end-user services running on Windows or accessible online via web browsers. Our analysis will be scoped further to target more applications, especially cryptographic keys and disk encryption software such as TrueCrypt and BitLocker in our consequent article.
