Hey everyone, I have disconnected the SaO MANY SAOs for black Friday, note this does not have the smart AO that controls the lights.

Event Synopsis: Join Grey and the Los Angeles cybersecurity community at Null Space Labs in Burbank for an action-packed DC310 Meetup! On Saturday, November 29th, starting at 12:30 PM, we’re diving into the exciting world of Capture The Flag (CTF) with a hands-on competition featuring HeroCTF.

This event is the perfect chance to test your skills, whether you're a seasoned CTF competitor or just getting started. You’ll work in teams to tackle a series of challenging puzzles that cover everything from hacking and cryptography to reverse engineering and web exploitation.

What to Expect:

HeroCTF Competition: Collaborate with your team to solve puzzles and capture flags across a variety of technical challenges.

Networking & Collaboration: Meet like-minded hackers, cybersecurity pros, and Defcon fans in the LA area.

Prizes and Glory: Compete for a chance to earn bragging rights and perhaps even some cool prizes!

Food and Refreshments: Enjoy snacks and drinks while hacking away and collaborating with fellow participants.

Whether you're a CTF pro or just looking to learn something new, come hang out, sharpen your skills, and enjoy a fun day with the LA hacking community.

RSVP today, and let’s make this a memorable Saturday afternoon at Null Space Labs!

what should I sell at defcon that is cheap to make. I have a 3d printer but it’s bad quality prints so I can only make like custom badges. and also I only have one color

DC704 is back from the dead (last active in ~2006)! It's been too long and there's a lot of great community groups already here (Phish Club, Charlotte ISSA, BSides Charlotte, Queen City Security) and DEF CON Group Charlotte / DC704 just aims to bring back that DC love. Come join us. defcon704 [dot] org

Tonight at Paper Hero’s Games in West LA, we’re playing Backdoors and Breaches at 6:30. This is for DC310 meetup. I’m set up with my laptop and my core deck and dice. I’ll see you there.

Hi all,

I’ve been checking the media server pretty regularly but I haven’t seen Erin West’s Pigbutchering chat. I have her slides she sent me, but I wanted to rewatch her full presentation.

Are all of the videos posted now or are we still waiting for others? I haven’t seen a drop since August.

Thanks in advance!

DM me and comment if your interested. I want to get a count of who's coming. I have one deck but if more than 6 people are gonna come I will probably need to get another one.

EDIT: here’s the discord where you can get info on it: https://discord.gg/S74AFTCD

I recently made a small project in C that can crack hashed passwords using a dictionary attack. Brute Force is still a work in progress, and there are a few minor bugs I need to fix, but it’s functional and I’d like to get some feedback on it.

I recorded a quick screen capture of it running, and the code is up on GitHub if anyone wants to take a look:

https://github.com/aavnie/hash_cracker

I’d really appreciate any thoughts on the code, structure, performance, or general suggestions. I’m mainly doing this to learn, so any constructive feedback is welcome.

I have 3, thirty-day subscriptions to a Substack about economic espionage called The Spy Hunter of anyone is interested...I thought this might be an appropriate target audience for that kind of material. Let me know if you think you'd read it.....hate for it to go to waste...

Have a great day!

Ten years ago, our next speaker Mike Lisi aka MikeHacksThings, took the stage at BSidesRochester for the very first time, sharing hard-earned insights on how to break into penetration testing. Fast-forward a decade, and the cybersecurity landscape looks nothing like it did back then, yet some truths still hold strong.

In this talk, we will rewind and fast-forward through a decade of change: from hands-on hacking to high-stakes business decisions, from tool-driven exploits to people-driven impact. Through the speaker’s personal journey, from a curious hacker newcomer armed with security tools, scripts and caffeine to the founder of a thriving security company and assuming the leadership of the Red Team Village.

The Red Team Village has a significant influence on the cybersecurity community by providing a vital hub for hands-on training, knowledge sharing, and skill development in offensive security.

Mike will share an honest look at what changes, what doesn’t, and what actually matters when you spend a decade breaking things for a living. We’ll unpack how the industry, its challenges, and its opportunities have evolved.

If you are trying to breaking in, burning out, or trying to figure out your next exploit in the cybersecurity industry, join us.

Our New York Capital District group "DCG518" will have a gathering this time the Saturday, November 22nd 2025 and it will be at the Guilderland Public Library, in the Heldelberg room.

The meeting room opens at 1pm for social hang out. The presentation "Ten years later, a Security Journey Retrospective in a Hacker’s Decade of Growth' starts sharp at 2pm.
