Revision as of 07:35, 13 December 2010 by Andrewtappert (added new tool (volatilitux), added link to SL data sheet, created new section for challenges and added sstic 2010, added links to Volatility threads dealing with Linux, organized tools by type)
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.
