lmc - Linux Memory Capturer

Original author

Linux Memory Grabber - A script for dumping Linux memory and creating Volatility(TM) profiles.

Since Hal Pomeranz's code has not been updated for more than 5 years, I've made some changes and simplified the complexity of the installation process.
My Blog post :


Getting Started

Here is an example of using the lmc tool, which includes using Volatility(TM) to analyze the captured image. It was tested on Ubuntu version 16.04, 17.10, and 18.04. and Kali Linux 2018.3


The following preparations are necessary for smooth progress.

cpuu@ubuntu:~$ sudo apt-get install gcc git
cpuu@ubuntu:~$ sudo apt-get install yara
cpuu@ubuntu:~$ sudo apt-get install python-pip
cpuu@ubuntu:~$ sudo -H pip install --upgrade pip
cpuu@ubuntu:~$ sudo -H pip install distorm3 pycrypto openpyxl Pillow


The process of downloading and installing the script from github is as follows,

cpuu@ubuntu:~$ git clone
cpuu@ubuntu:~$ cd lmc
cpuu@ubuntu:~/lmc$ sudo ./

Capturing the Memory

Now, as root, run "sudo ./lmc". This is interactive mode and the user will be prompted for confirmation before lmc builds a LiME module for the system and/or creates a Volatility(TM) profile.

cpuu@ubuntu:~/lmc$ sudo ./lmc

Two questions will be asked.

  • Try to build LiME kernel module? [N|y]
  • Compile profile for this system? [N|y]

If this is your first time, select 'y' for both.

cpuu@ubuntu:~/lmc$ sudo ./lmc

Try to build LiME kernel module? [N|y] y

Everything else is automated. After the script runs, you will have a new directory named ../capture/<hostname>

the directory will contain:

filename description the RAM capture Volatility(TM) profile copy of target's /bin/bash
volatilityrc prototype Volatility config file

Analysing Memory dump

At the end of the capture, you can see that the capture directory is created.

cpuu@ubuntu:~/lmc$ cd capture/
cpuu@ubuntu:~/lmc/capture$ cd osboxes-2018-09-18_22.03.28/
cpuu@ubuntu:~/lmc/capture/osboxes-2018-09-18_22.03.28$ ls -l volatilityrc 
-rw-r--r-- 1 root root 235 Sep 18 22:04 volatilityrc

There is a file called volatilityrc. This file defines the appropriate locations for the captured memory and plugin.

cpuu@ubuntu:~/lmc/capture/osboxes-2018-09-18_22.03.28$ cat volatilityrc 

When you run volatility, you can specify --conf-file=../capture/osboxes-2018-09-18_22.03.28/volatilityrc and execute the desired plug-in.


Running linux_banner plugin to test capture, leveraging the prototype volatilityrc

cpuu@ubuntu:~/lmc $ cd volatility/
cpuu@ubuntu:~/lmc/volatility$ python --conf-file=../capture/osboxes-2018-09-18_22.03.28/volatilityrc linux_banner

Volatility Foundation Volatility Framework 2.6
Linux version 4.15.0-34-generic (buildd@lgw01-amd64-047) (gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)) #37-Ubuntu SMP Mon Aug 27 15:21:48 UTC 2018 (Ubuntu 4.15.0-34.37-generic 4.15.18)


This plugin prints the list of active processes starting from the init_task symbol and walking the task_struct->tasks linked list. It does not display the swapper process. If the DTB column is blank, the item is likely a kernel thread.

cpuu@ubuntu:~/lmc/volatility$ python --conf-file=../capture/osboxes-2018-09-18_22.03.28/volatilityrc linux_pslist
