Thursday, January 11th – 6:30pm @ Virtual

Hello Hackers!

Note the time change! We start at 6:30PM instead of the traditional 6:12PM at the request of our speaker, because…

This month, we will be joined by @4lph4V all the way from India (11.5 hours ahead of Central time) who will be presenting his talk titled “Transitioning into Offensive Security”:

This session delves into the practical aspects and challenges faced when embracing an offensive security role. From acquiring essential skills to navigating the evolving landscape, gain valuable insights to empower your transition into the realm of offensive cybersecurity

Thursday, December 14th – 6:12pm @ Virtual

Hello Hackers!

This month, we will be joined by @MiloSilo_Hacks who will be presenting some prompt engineering attacks to bypass ChatGPT restrictions:

I have created TTPs and two tools to assist in manipulating generative AI which bypass all the ethical boundaries of ChatGPT. I have a heads-up display ratings system you can add into ChatGPT to understand how it thinks. This talk will include a live demo.

I’m peter Halber, aka Milosilo. I’m a senior red teamer at a big corporate bank, and also former counterintelligence agent. I combined my skill sets to redteam generative AI via prompt engineering. When I’m not hacking, I like to spend time with friends and family. I enjoy cooking, the outdoors, and playing flight simulator. I also have great jokes.

As usual, we will be meeting online at https://cafe.cyberia.club/dc612.

Talk starts at 6:12 PM U.S. Central, but feel free to hop in early and chat.

Thursday, November 9th – 6:12pm @ Virtual

Hello Hackers!

This month, we will be joined by @TactiFail who will be presenting his talk “Reflections on Reflection”:

Reflection is a technique used in programming to inspect the running code at runtime. This allows for all sorts of weirdness, from simply reading private variables to modifying them directly and calling private methods. This talk goes over what reflection is, roughly how it works, and how it can be used to work around those pesky “private” access modifiers.

Tacti is a senior (or principal, depending on who you ask) penetration tester at a healthcare-adjacent organization. He runs DC612, a Minnesota Defcon group (check them out some time) and sometimes cooks passable meals.

As usual, we will be meeting online at https://cafe.cyberia.club/dc612.

Talk starts at 6:12 PM U.S. Central, but feel free to hop in early and chat.

Thursday, October 12th – 6:12pm @ Virtual

Hello Hackers!

This month, we will be joined by Brian Halbach who will be presenting his talk “Security Flaw Safari: Reading Between the Lines and Hunting Security Risks”:

This talk covers the methodology used for hunting previously unknown security risks and how to go on an adventure to read between the lines and uncover the juicy secrets the documentation won’t directly tell you. This talk will also help show a way to estimate if a research project will take 50 hours or 50 years as well as strategies on how to effectively learn a new technology and peel back the layers of complexity until you can find out what is really going on under the hood. There will also be examples and discussion from real world case studies. Audience members should be ready to participate and are welcome to share their own stories and thoughts (assuming they are legally allowed).

Brian is a Senior Security Consultant at InGuardians with past experience in help-desk and network engineering roles. Recognizing organizational security gaps in those previous roles, he transitioned to red teaming and penetration testing. He enjoys tackling complex security issues and consulting with clients to find non-obvious solutions.

As usual, we will be meeting online at https://cafe.cyberia.club/dc612.

Talk starts at 6:12 PM U.S. Central, but feel free to hop in early and chat.
