REMnux is an open source Ubuntu-based distribution of Linux specifically designed for malware analysts who are looking for a free alternative operating system to Microsoft Windows, in order for them to reverse-engineering malicious software.
Features at a glance
Key features include the ability to examine web browser malware, management of network interactions, decode and extract artifacts, examine document files, investigate Linux malware, statically examine PE files, examine file properties and contents, process multiple samples, examine memory snapshots, as well as to edit and view a wide range of files.
Distributed as a Live DVD and virtual appliance archive
The operating system can be downloaded as a single Live DVD ISO image that supports both 32-bit and 64-bit hardware platforms and must be written on DVD discs or USB flash drives of 2GB or higher capacity in order to boot it from the BIOS of a PC, as well as a virtual appliance archive (OVA) for the VirtualBox and VMware virtualization software.
It features a standard boot loader that can be found on a wide range of Linux distributions based on Ubuntu, allowing the user to start the live environment with default options or in safe graphics mode by forcing the VESA framebuffer, perform a system memory (RAM) test, and boot an existing operating system from the first disk.
Minimal, fast and productive desktop environment powered by LXDE
By default, the Live CD is engineered to open a terminal emulator from the get-go. It uses the Lightweight X11 Desktop Environment (LXDE) with a dark artwork and a single panel located on the bottom edge of the screen, from where the user can access the applications or interact with running programs.
Among the preinstalled apps, we can mention SciTE text editor, wxHexEditor hex editor, Wireshark network scanner, XMind mind mapping tool, SQLite database browser, Mozilla Firefox web browser, and LXMusic music player.
Summing up, REMnux is definitely not a Linux distribution for the regular user. It is based on an older, unsupported version of Ubuntu (11.10 - Oneiric Ocelot), but delivers a neat collection of other useful features that will help malware analysts to reverse-engineer malicious software.
