LiMEaide is a python application designed to remotely dump RAM of a Linux client and create a volatility profile for later analysis on your local host. I hope that this will simplify Linux digital forensics in a remote environment. In order to use LiMEaide all you need to do is feed a remote Linux client IP address, sit back, and consume your favorite caffeinated beverage.

python3 limeaide.py <IP>

and magic happens.

• For more detailed usage checkout the wiki
• For editing the configuration file see here
• Import old modules or external modules, just copy the module *.ko into the profiles directory.

./profiles/

limeaide.py [OPTIONS] REMOTE_IP
-h, --help
    Shows the help dialog

-u, --user : <user>
    Execute memory grab as sudo user. This is useful when root privileges are not granted.

-p, --profile : <distro> <kernel version> <arch>
    Skip the profiler by providing the distribution, kernel version, and architecture of the remote client.

-N, --no-profiler
    Do NOT run profiler and force the creation of a new module/profile for the client.

-C, --dont-compress
    Do not compress memory file. By default memory is compressed on host. If you experience issues, toggle this flag. In my tests I see a ~60% reduction in file size

--delay-pickup
    Execute a job to create a RAM dump on target system that you will retrieve later.  The stored job
    is located in the scheduled_jobs/ dir that ends in .dat

-P, --pickup <path to job file .dat>
    Pick up a job you previously ran with the --delayed-pickup switch.
    The file that follows this switch is located in the scheduled_jobs/ directory
    and ends in .dat

-o, --output : <name>
    Change name of output file. Default is dump.bin

-c, --case : <case num>
    Append case number to front of output directory.

--force-clean
    If previous attempt failed then clean up client

• DEB base

sudo apt-get install python3-paramiko python3-termcolor

• RPM base

sudo yum install python3-paramiko python3-termcolor

• pip3

sudo pip3 install paramiko termcolor

In order to build a volatility profile we need to be able to read the debugging symbols in the LKM. For this we need to install dwarfdump. If you encounter any issues finding/installing dwarfdump see the volatility page here

• DEB package manager

sudo apt-get install dwarfdump

• RPM package manager

sudo yum install libdwarf-tools

By default LiMEaide will automatically download and place LiME in the correct directory. However, if you are disconnected from a network proceed with manual installation method in the section below.

In order to use LiME you must download and move the source into the LiMEaide/tools directory. Make sure the the LiME folder is named LiME. The full path should be as follows: NOTE: If you would like to build Volatility profiles, you must use my forked version of LiME. This provides debugging symbols used by dwarfdump.

LiMEaide/tools/LiME/

How to...

1. Download LiME v1.7.8.2
2. Extract into LiMEaide/tools/
3. Rename folder to LiME

• Only supports bash. Use other shells at your own risk
• Modules must be built on remote client. Therefore remote client must have proper headers installed.
  • Unless you follow this guide for compiling external kernel modules

• The idea for this application was built upon the concept dreamed up by and the Linux Memory Grabber project
• And of course none of this could be possible without the amazing LiME project
