Cork|Sec 144

Running since June 2013, every month we have 1-2 talks focused on Security or Technology - followed by socialising with like minded people – and you can find out exactly what to expect about the night and the venue on the What We're About section of our Meetup page. Past talk details are on our wiki on http://corksec.com/. All people with any sort of an interest or level of knowledge in Security, Hacking and Emerging Technology are more than welcome to attend and feel free to bring like minded colleagues and friends.

CorkSec is made possible through generous sponsorship from our Platinum Sponsor Trend Micro, Gold Sponsor CyberSkills , as well as our Silver and Bronze Sponsors featured prominently on the night.

Doors open at 19:00 with talks starting at 19:15. Talks below

TALK 1: Attacking LLM Detectors with Homoglyph-Based Attacks by Aldan Creo
This session explores an attack vector, homoglyph-based attacks, that effectively evades state-of-the-art AI-generated text detectors.
We'll begin by explaining the idea behind homoglyphs, characters that look similar but are encoded differently. You'll learn how these can be used to manipulate tokenization and evade detection systems. We'll cover the mechanisms of how homoglyphs alter text representation, discuss their impact on existing LLM detectors, present a comprehensive evaluation of their effectiveness against various detection methods, and see how we can protect detectors against these attacks.
Join us for an immersive exploration and stay ahead of evolving threats!

TALK 2: TLS, PKI and certificate revocation: theory vs practice -
Ireneusz Pastusiak

Today I will give a brief overview of the theory behind the certificate revocation in PKI and TLS. We will then deep dive into the present-day reality of server- and client-side certificate revocation, how it is different from the theory, and what can we do about it.
