Professionally offensive, personally friendly

Hey, I'm Marba$

I break things on purpose, build odd little hardware projects, and grow security communities where people feel welcome.

Speaking & community

President of the Maine nonprofit behind BSides Maine and DC207. Hack local, build together.

Founder & lead organizer of Maine's community-run security conference.

Lead for the DEF CON Group covering Maine. Local hangs, all skill levels.

Helping people find their footing in offensive security training.

A comprehensive guide to discovering, reporting, and publishing security vulnerabilities. Published by Packt.

The oldest pwnagotchi seller around. Gear, builds, and experiments, plus over 8,500 pwnagotchis outfitted for hackers everywhere.

The shop and project bench for the hardware and oddities I put together.

A few CVEs and writeups live on the blog. Dozens more went out quietly or through other channels.
