Block on Finding and Fixing Security Risks with OpenAI

From the creator

“Now you know and now you can take action before someone else knows.” A weakness in your code can be part of a much bigger attack. Seeing how those weaknesses connect gives defenders a clearer picture of where to act. Block’s Chief Information Security Officer, James Nettesheim, shares how OpenAI’s cyber capabilities can help uncover software vulnerabilities and connect them into a path to compromise. Then comes the work that turns discovery into action: identify the affected software and its owner, propose a patch, and verify that the fix works, with a person guiding deployment. Watch James on what AI can make possible for cybersecurity teams—from vulnerability analysis and hidden security risks to patch verification and the next steps defenders can take.

Makers residency 4th edition

Your idea can be anything. At our last workshops, people built plant-based nutrition businesses, a way to measure planetary resilience, crochet headwear and a way to connect lonely people living in the same building. An asset manager went on to raise an additional £25M on their fund within nine months. The fourth workshop is a full day at KOKO with Nick Sarafa, learning to build with Claude Code. Bring the thing you keep meaning to start. We’ll bring the pizza.
