Joachim Metz is a Digital researcher, IT/IS specialist.

'''Memory Analysis''' is the science of using a [[Memory Imaging|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:
  
In 2006 he started working in the field of computer forensics as a digital forensic investigator at Hoffmann Investigations.
+
* [[Windows Memory Analysis]]
At that time Hoffmann Investigations carried out digital forensic investigations for organisations (private law).
+
* [[Linux Memory Analysis]]
  
Before that he worked in multiple Information Communication Technology (ICT) disciplines like: system and network administration, programming, deployment, etc. and also Information Security (IS).
+
== OS-Independent Analysis ==
He has been working in the field of digital forensics for several years now.
+
  
(Philosophy warning!!!) In his opinion digital forensic investigators should be transparent in both their findings and methods.
+
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.
The statement "the tool provided me with the evidence" just does not cut it.
+
In his work he experienced a lot of serious errors in 'digital forensic software' and corresponding human interpretation, e.g. tools that represent the FAT access date as a date and time value and is interpreted as such. He has put a lot of effort in providing alternatives and means to verify findings by breaking open file formats and improving file recovery methods.
+
  
(Ancient history alert!!!) For him breaking open file formats dates back to Might and Magic 3 save games and recovering deleted and corrupted files under DOS using PCTOOLS.
+
== Encryption Keys ==
  
(Marketing alert!!!) Some of his recent work are file format libraries like: [[libewf]], [[liblnk]], [[libmsiecf]], [[libnk2]], [[libpff]] and [[libesedb]]
+
Various types of encryption keys can be extracted during memory analysis.
and the proof-of-concept carving tool called [[ReviveIt (revit)|revit]], which keeps surprising him because of its versatile application even in recovering NTFS-compressed files.

The challenge he likes about the field of digital forensics is that there is a lot out there still to be discovered ;-)

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:

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.
