Rekall is the stand-alone continuation of the Volatility Technology Preview (TP) version, aka the scudette branch.

One of Rekalls goals is to provide better integration with GRR by improved modularity of the framework and having memory acquisition drivers.

Contents

Memory acquisition drivers

The drivers can be found under:

rekall/tools/linux
rekall/tools/osx
rekall/tools/windows

Linux

To build the kernel module for the current kernel version, make sure you have a working build environment and the kernel headers installed. Change into this directory and run make:

cd rekall/tools/linux/
make

The acquisition driver is named pmem.ko.

To load the driver:

sudo insmod pmem.ko

To check if the driver is running:

sudo lsmod

The driver create a device file named:

/dev/pmem

To unload the driver:

sudo rmmod pmem

To read acquire the memory just read from the device file. e.g.

dd if=/dev/pmem of=image.raw

For more information see:

rekall/tools/linux/README

Mac OS X

For more information see:

rekall/tools/osx/OSXPMem/README

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:

rekall/tools/windows/winpmem/binaries

E.g.

rekall/tools/winpmem/binaries/amd64/winpmem.sys

A standalone tool for imaging memory that uses an embedded copy of the pmem driver can be found as winpmem.exe in:

rekall/tools/winpmem/executables/Release/

To load the driver:

winpmem.exe -l

The device filename is (This can not be changed without recompiling):

\\.\pmem

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:

winpmem.exe image.raw

To unload the driver:

winpmem.exe -u 

For more information see:

rekall/tools/windows/README
