Turns out: a lot. We're diving into a sneaky GitHub Actions vulnerability where your authentication tokens get stored inside Docker image layers and published to public registries, where anyone can grab them. A race follows, between your workflow finishing and attackers downloading your Docker layers to loot the secrets hiding inside. Learn how this works, how to exploit it, and how to make sure your pipelines aren't leaking secrets to the world. **"Securing the SDLC: From Container Images to AI Agents" -** Tharinda Basnayake This presentation examines the evolution of supply chain security challenges from container images to AI agents. We'll explore how modern development practices create new attack vectors, from containers running hundreds of unnecessary packages to AI agents accessing enterprise systems without proper security controls **SPEAKERS:** **Rishi C (@rxerium)** Rishi is a London-based cyber security researcher specialising in zero days, vulnerability research, threat intelligence, OSINT and risk management, dedicated to strengthening cyber resilience through proactive discovery and defence. **Gaetan Ferry (@*mabote*)** Gaetan is a security researcher with a decade of experience uncovering software vulnerabilities.

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** GitHub Copilot is rapidly changing how developers write, understand, and maintain code. Powered by generative AI and deeply integrated into modern development environments, Copilot acts as an intelligent coding assistant, helping developers move faster while maintaining quality and focus. In this session, we’ll explore what GitHub Copilot is, how it works, and where it fits into a real-world developer workflow. We’ll break down what Copilot can (and cannot) do, where it can be used, and how licensing differs for individuals and organizations. Most importantly, this talk goes beyond theory with a live, hands-on demo showcasing Copilot inside the IDE and on GitHub, demonstrating how it can assist with code generation, refactoring, learning new APIs, and accelerating day-to-day development tasks. Designed for developers, technical leads, and engineering managers, this session provides a practical introduction to AI-assisted development, highlights best practices for getting value from Copilot, and closes with guidance on how to continue learning and evolving alongside this rapidly advancing tool. Attendees will leave with a clear understanding of how GitHub Copilot can enhance productivity, improve developer experience, and fit into modern software teams today, not someday. **YouTube Link** TBA
