Linux memory monitor tools12/15/2023 ![]() Ideally, the lime.ko file will be renamed using the format lime-.ko at the end of make: $ make Run the make command inside the src folder. Get LiME with: $ git clone ĭeflate.c disk.c hash.c lime.h main.c Makefile Makefile.sample tcp.c Linux Memory Extractor ( LiME) is a popular tool for acquiring memory on a Linux system. Since you probably do not have a memory dump available, you can take a memory dump of your test VM and use that to perform memory forensics. Such information is often collected and stored to analyze how the intrusion happened and its impact. In an actual forensics event, this could come from a compromised or hacked system. ![]() ![]() Most of these packages provide the required kernel information and tools to compile the code: $ yum install kernel-headers kernel-devel gcc elfutils-libelf-devel make git libdwarf-tools python2-devel.x86_64-y Part 1: Use LiME to acquire memory and dump it to a fileīefore you can begin to analyze memory, you need a memory dump at your disposal. If you are using a Debian-based distro, use the equivalent apt-get commands. Always use a test virtual machine (VM) to try things out until you are comfortable using the tools and understand how they work.īefore you get started, install the requisite tools.Do not try any of these steps on a production system or your primary machine.Don't worry it isn't as difficult as it sounds. Red Hat Enterprise Linux release 8.3 (Ootpa)Ī note of caution: Part 1 involves compiling and loading a kernel module. I used the following test system for this tutorial, but it will work on any Linux distribution: $ cat /etc/redhat-release The second part uses Volatility to read and process information from this memory dump.The first part deals with acquiring the physical memory and dumping it into a file.However, there's a problem: Before you can process this information, you must dump the physical memory into a file, and Volatility does not have this ability. Volatility is an open source tool that uses plugins to process this type of information. Memory forensics is a way to find and extract this valuable information from memory.
