How availability of tools does not make it easier?

I’m not sure but I’m guessing his point is that black hats would more likely write their own software and script kiddies would rather not use abandoned software?

In any case, there wasn’t any shortage of tools even in the 90s. Nor places to research them either. Plus systems were less security conscious then too so the barrier for entry was a little lower.

This is not abandoned software there was an active discussion on adding domain fronting just a few weeks back.

I make most of my commits to the Dev branch and I am selective about pushing things to the Master branch. Check the releases page for a good indication of activity. I will also be pushing out an update in the next couple of days that adds the ability to execute shellcode using 4 different methods (Windows only).
