Hacking Polymarket on 04/05/2026
Polymarket is a platform where people can bet on real-world events, political and otherwise.

Polymarket gamblers have threatened a journalist because his story was being used to verify an event. And now, gamblers are takin [...]

This capability will have m [...]
6 Lessons Security Leaders Must Learn About AI and APIs by Tim Erlin on 28/04/2026
Most organizations treating AI security as a model problem are defending the wrong layer. Security teams filter prompts, patch jailbreaks, and tune model behavior, which is all necessary work, while the actual attack surface sits largely unexamined underneath. That surface is the API layer: the endpoints AI systems use to retrieve data, call tools, and take action on behalf of users. This isn' [...]

The Governance Gap: How the EU AI Act Makes API Security a Compliance Imperative by Julian Richter on 24/04/2026
Your legal team just handed you a 400-page document and said "figure out compliance." The EU AI Act is live, your organization falls under its scope, which is broader than many expect. Even non‑EU companies must comply if their AI systems are used, deployed, or produce effects within the European Union. In practice, that means that global organizations building or integrating AI models cannot tre [...]

Attacking the MCP Trust Boundary by Chandler Johnson on 22/04/2026
Every secure API draws a line between code and data. HTTP separates headers from bodies. SQL has prepared statements. Even email distinguishes the envelope from the message. The Model Context Protocol (MCP), the fast-growing standard for connecting AI agents to external services, inherits that gap from the models it sits on top of. Its central premise is that a language model reads tool descripti [...]

Why API Discovery Is the First Step to Securing AI by Tim Erlin on 21/04/2026
TL;DR AI risk doesn’t live in the model. It lives in the APIs behind it. Every AI interaction triggers a chain of API calls across your environment. Many of those APIs aren’t documented or tracked. That’s your real exposure. Shadow API discovery gives you visibility into those hidden endpoints, so you can find them before attackers do. If you don’t know which APIs your AI relies on, you can [...]
