Here are some projects I've worked (or am working) on:

BPATTY

Brian's Pentesting and Technical Tips for You is a GitHub project, and its purpose is to be a quick reference for pentesting, hardware/software configs, VM setups, and basically everything else that I used to keep in Evernote, OneNote, stickies, scratch paper, Notepad, etc...

Tommy Boy

A vulnerable machine I designed for practicing pentesting. You can grab it on VulnHub and read more "behind the scenes" info on my blog post about it.

Billy Madison

Billy is another vulnerable machine (based on the popular 90s movie) I made for VulnHub. There's a bit more background and history info on this page.
