I really appreciate your suggestion to use only Free Software. That said, you immediately follow that suggestion up with a reference to "commerical software". This implies that "commercial software" is somehow different or "at odds with" Free Software. This is a common misunderstanding in our circles and I'd prefer to not see the same confusion repeated here (if possible). Free Software is software that grants its users 4 essential freedoms (these are well documented on fsf.org) while non-free software is any software that is not free (as in freedom). It's about the amount of freedom granted and has nothing to do with cost. At the end of the day, there are only really 2 groups of software: free and non-free. What you pay for any instance of either is totally unrelated.
While I did get into LEDE for the rootkits and the network defense, I think you may be a bit too isolated from the average developers/admins.
I wouldn’t use SVGs either. Aren’t those like executable images? No PDFs either, unless it’s a honeypot server.
I’ve been checking out Bro, it’s basically an event based scripting language for packet analysis.
I’m curious, what do you guys think of the skill of these botnet developers?
