The landscape of open-source malware analysis tools improves every day. A malware analysis lab can be thought of as a set of entry points into a tool chain. The main entry points are a file, a URL, a network traffic capture, and a memory image. This talk is an examination of the major open-source tools that satisfy the analysis requirements for each of these entry points. Each tool's output can potentially feed into another tool for further analysis. The ing of one tool to the next in a tool chain allows one to build a comprehensive automated malware analysis lab using open-source software.
