Linux Memory Analysis Tools
- The Forensic Analysis Toolkit (FATKit) is a cross-platform, modular, and extensible digital investigation framework for analyzing volatile system memory. (Publication Date: 2006; Availability/License: not available)
Open Source Projects:
- The Volatility Framework is a collection of tools, implemented in Python, for the extraction of digital artifacts from volatile memory (RAM) samples. Support for Linux is experimental (see Volatility mailing list threads referenced below). (Availability/License: GNU GPL)
- Foriana is tool for extraction of information such as the process and modules lists from a RAM image using logical relations between OS structures. (Availability/License: GNU GPL)
- Draugr is a Linux memory forensics tool written in Python. (Availability/License: GNU GPL)
- Volatilitux is another Linux memory forensics tool written in Python. (Availability/License: GNU GPL)
- Second Look from Pikewerks Corporation can analyze live memory or stored snapshots (physical memory images). It can be used to detect rootkits and other kernel-hooking malware, as well as obtain forensic information about the state of the system. It has command-line and GUI interfaces, and reverse engineering capabilities including built-in disassembly and hexadecimal data views. An online reference kernel repository provides baselines for verification of thousands of distribution stock kernels. As of November 2010, it supports x86 and x86_64 targets running kernels 2.6.8 to 2.6.35. (Availability/License: commercial)
Linux Memory Analysis Challenges
- The Digital Forensic Research Workshop 2008 Forensics Challenge focused on the development of Linux memory analysis techniques and the fusion of evidence from memory, hard disk, and network.
- Challenge SSTIC 2010 (French) dealt with analysis of physical memory from a mobile device running Android.
