writes "A security expert has released a stripped-down Ubuntu distribution designed specifically for reverse-engineering malware. The OS, called REMnux, includes a slew of popular malware-analysis, network monitoring and memory forensics tools the comprise a very powerful environment for taking apart malicious code. REMnux is the creation of Lenny Zeltser, an expert on malware reverse engineering who teaches a popular course on the topic at SANS conferences. He said that he put the operating system together after years of having students ask him which tools to use and what works best. He originally used Red Hat Linux but recently decided that Ubuntu was a better fit.
