REMnux™ is a free Linux toolkit for assisting malware analysts with reverse-engineering malicious software. It strives to make it easier for forensic investigators and incident responders to start using the variety of freely-available tools that can examine malware, yet might be difficult to locate or set up.
The heart of the project is the REMnux Linux distribution based on Ubuntu. This lightweight distro incorporates many tools for analyzing Windows and Linux malware, examining browser-based threats such as obfuscated JavaScript, exploring suspicious document files and taking apart other malicious artifacts. Investigators can also use the distro to intercept suspicious network traffic in an isolated lab when performing behavioral malware analysis.
