Plaso (plaso langar að safna öllu) is the Python based back-end engine used by tools such as log2timeline for automatic creation of a super timelines. The goal of log2timeline (and thus plaso) is to provide a single tool that can parse various log files and forensic artifacts from computers and related systems, such as network equipment to produce a single correlated timeline. This timeline can then be easily analysed by forensic investigators/analysts, speeding up investigations by correlating the vast amount of information found on an average computer system. Plaso is intended to be applied for creating super timelines but also supports creating [http://blog.kiddaland.net/2013/02/targeted-timelines-part-i.html targeted timelines].
  
One of Rekalls goals is to provide better integration with [[GRR]] by improved modularity of the framework and having memory acquisition capability.[http://docs.rekall.googlecode.com/git/overview.html#_history]
+
The Plaso project site also provides [[4n6time]], formerly "l2t_Review", which is a cross-platform forensic tool for timeline creation and review by [[David Nides]].

+
=== Windows ===
+
Since recent versions of Windows require a signed driver rekall comes with both pre-built (signed binary) and source versions of the driver.
+
 
+
Both the i386 and amd64 binary version of the driver can be found in the directory:
+
<pre>
+
rekall/tools/windows/winpmem/binaries
+
</pre>
+
 
+
E.g.
+
<pre>
+
rekall/tools/winpmem/binaries/amd64/winpmem.sys
+
</pre>
+
 
+
A standalone tool for imaging memory that uses an embedded copy of the pmem driver can be found as winpmem.exe in:
+
<pre>
+
rekall/tools/winpmem/executables/Release/
+
</pre>
+
 
+
To load the driver:
+
<pre>
+
winpmem.exe -l
+
</pre>
+
 
+
The device filename is (This can not be changed without recompiling):
+
<pre>
+
\\.\pmem
+
</pre>
+
 
+
Note that running dd directly on this device file can crash the machine.
+
Use the winpmem.exe tool instead because it handles protected memory regions.
+
 
+
To read and acquire the physical memory and write it to image.raw:
+
<pre>
+
winpmem.exe image.raw
+
</pre>
+
 
+
To unload the driver:
+
<pre>
+
winpmem.exe -u
+
</pre>
+
 
+

Plaso (plaso langar að safna öllu) is the Python based back-end engine used by tools such as log2timeline for automatic creation of a super timelines. The goal of log2timeline (and thus plaso) is to provide a single tool that can parse various log files and forensic artifacts from computers and related systems, such as network equipment to produce a single correlated timeline. This timeline can then be easily analysed by forensic investigators/analysts, speeding up investigations by correlating the vast amount of information found on an average computer system. Plaso is intended to be applied for creating super timelines but also supports creating targeted timelines.

The Plaso project site also provides 4n6time, formerly "l2t_Review", which is a cross-platform forensic tool for timeline creation and review by David Nides.
