In this post, we provide a detailed analysis of an interesting Excel 4.0 XLM macrosheet maldoc distribution campaign that is tied to a variety of executable payloads, a subject matter we'll be covering in a future blog.

Our CTO, Pedram Amini, and colleague Ero Carrera have open-sourced all the materials from a two-day reverse engineering class they taught over the years at BlackHat, the last instance being at Blackhat 2009 Federal. Written in LaTeX + Beamer, the course materials can be rendered in both slideshow (PDF) and article (PDF) modes. Additionally, the courseware includes malware samples and all requisite references, scripts, tools, exercises, and solutions.
