Evil Clippy is described as:  "A cross-platform assistant for creating malicious MS Office documents. Can hide VBA macros, stomp VBA code (via P-Code) and confuse macro analysis tools. Runs on Linux, OSX and Windows."  I didn't have much luck with some of the other features but the feature that was of most interest to me, hiding macros, was functional.

We work with small businesses and the goal is to hide -- well enough, meaning that we want to show that if a small business is attacked, assigning attribution is difficult.  We're not hiding from competent investigators, we're just hiding from the average Joe. 

The other day I wrote about EmbedInHTML and like most things, I wanted to learn more about the mechanics.  While poking around, I found an article, HTML Smuggling, which I guess is the technical term but it started to spell things out for me.  The article is worth reading and there's no need for me to rehash the entire post but the gist of it is that we're taking a document, converting it to Base64, and we're passing that across to the browser with an auto download function.

There are lots of tools that overlap and this one is no different.  It has a few tricks that I haven't seen in other tools and it has some similar features to others.  I didn't play with the Pro version but I did ask the author if the Pro version was still capable of evading a/v and he said yes.  Before I move on, the description of the product states:  "macro_pack is a tool by @EmericNasi used to automatize obfuscation and generation of Office documents, VB scripts, shortcuts, and other formats for pentest, demo, and social engineering assessments."
