At the IEEE Security and Privacy conference in May 2011, Brendan Dolan-Gavitt presented a novel system, [http://www.cc.gatech.edu/~brendan/Virtuoso_Oakland.pdf Virtuoso], that was able to perform operating-system independent memory analysis. Using virtual machine introspection accompanied by a number of formal program analysis techniques, his system was able to monitor the machine-level instructions and behavior of application actions (listing processes, network connections, etc) and then automatically generate Volatility plugins that replicated this analysis.

Memory Analysis is the science of using a memory image to determine information about running programs, the operating system, and the overall state of a computer. Because the analysis is highly dependent on the operating system, it has been divded into the following pages:

Contents

OS-Independent Analysis

At the IEEE Security and Privacy conference in May 2011, Brendan Dolan-Gavitt presented a novel system, Virtuoso, that was able to perform operating-system independent memory analysis. Using virtual machine introspection accompanied by a number of formal program analysis techniques, his system was able to monitor the machine-level instructions and behavior of application actions (listing processes, network connections, etc) and then automatically generate Volatility plugins that replicated this analysis.

Encryption Keys

Various types of encryption keys can be extracted during memory analysis.
