Post-Quantum Cybersecurity: Exploring the Quantum Threat Landscape

Quantum computing is moving from a theoretical threat to a looming security crisis, and asymmetric cryptography is right in the crosshairs. This talk breaks down exactly how Shor’s algorithm dismantles the public-key foundations—like RSA and ECC—that secure everything from our web traffic to our identities.

We’ll cut through the hype to look at immediate, real-world risks—like “Harvest Now, Decrypt Later” and “Trust Now, Forge Later”—to help you pinpoint which of your systems and data are most vulnerable based on their lifespan and value. From there, we’ll dive into NIST’s new post-quantum standards and look at what they actually mean for your PKI, TLS, and enterprise architecture.

To bridge the gap between theory and execution, I’ll introduce pqcscan, an open source tool built to scan your infrastructure and hunt down vulnerable public-key implementations before adversaries can exploit them. We’ll wrap up by weighing the tradeoffs of post-quantum cryptography, hybrid rollouts, and quantum key distribution. You’ll walk away with a no-nonsense action plan for crypto agility, asset discovery, and the exact steps needed to build a quantum-resilient future.

The Coroner's Report: A Guided Autopsy of msfvenom's Windows Shellcode

when
fri 7-10 pm

This will be an interactive lab covering the reverse engineering of msfvenom’s stageless Windows x64 reverse TCP shellcode. We will cover the basics of Windows internals, x86_64 assembly code in Windows, as well as the obfuscation techniques used by the shellcode author in an attempt to hinder static analysis.

To participate in the lab, you will need a fresh Windows 11 VM with 2 cpu cores, 4GB of RAM, and 64GB of disk space allocated. A script will be provided to set up the VM with the necessary software and configurations before the talk (will post a github link in discord a week or 2 before the meetup).
