A weekly letter on offensive security, Active Directory, Azure, web and red team. Real attack paths and free cheatsheets. One focused idea per issue. No filler. Five minutes to read.
Practical, no-fluff quick references, the exact attack paths that land on real engagements. New ones drop regularly, free.
One focused idea every week, new technique to understand or something to try in your own lab, and the single best tool or resource I found.
The stuff no course covers: how to break into offensive security, which certs actually move the needle, and the moves I wish someone had shown me.
A private group of pentesters, red teamers and students. Ask questions, share techniques, and see how real operators actually think. I'm in there most days.
Deeper, paid cheatsheets covering full attack chains end to end, the tradecraft I don't publish for free. Buy only the ones you need, when you need them.
Guidance for OSCP, CRTO, CRTE and similar, from someone who's passed them. What actually matters, what's a rabbit hole, and how to not waste weeks grinding the wrong things.
Pentesters, red teamers, students grinding certifications like OSCP and security professionals who want practical tradecraft, not another theory dump.
You spend most of your day in meetings and feel like you never get real work done.
You have read the productivity books. You want something shorter and more practical.
You are good at your job but feel like you are always one step behind.
You want to work fewer hours without producing less, and you are not sure how yet.
I'm Marc, offensive security across Active Directory, web, cloud and mobile, with certifications that back it up: OSCP, CRTO, CRTE, AZRTE.
I kept the notes, playbooks and attack paths I actually used on real engagements. Breach Club is where I turn them into something you can use too. Nothing theoretical, only what I've seen work in practice.
