MCP vs A2A Explained: AI Agent Communication Protocols & Security Risks
Dive deep into the world of AI agent communication with this episode. Join hosts Caleb Sima and Ashish Rajan as they break down the crucial protocols enabling AI agents to interact and perform tasks: Model Context Protocol (MCP) and Agent-to-Agent (A2A).Discover what MCP and A2A are, why they're essential for unlocking AI's potential beyond simple chatbots, and how they allow AI to gain "hands and feet" to interact with systems like your desktop, browsers, or enterprise tools like Jira. The hosts explore practical use cases, the underlying technical architecture involving clients and servers, and the significant security implications, including remote execution risks, authentication challenges, and the need for robust authorization and privilege management.The discussion also covers Google's entry with the A2A protocol, comparing and contrasting it with Anthropic's MCP, and debating whether they are complementary or competing standards. Learn about the potential "AI-ification" of services, the likely emergence of MCP firewalls, and predictions for the future of AI interaction, such as AI DNS.If you're working with AI, managing cybersecurity in the age of AI, or simply curious about how AI agents communicate and the associated security considerations, this episode provides critical insights and context.Questions asked:(00:00) Introduction: AI Agents & Communication Protocols(02:06) What is MCP (Model Context Protocol)?

How to Hack AI Applications: Real-World Bug Bounty Insights
In this episode, we sit down with Joseph Thacker, a bug bounty hunter and AI security researcher, to uncover the evolving threat landscape of AI-powered applications and agents. Joseph shares battle-tested insights from real-world AI bug bounty programs, breaks down why AI AppSec is different from traditional AppSec, and reveals common vulnerabilities most companies miss, like markdown image exfiltration, XSS from LLM responses, and CSRF in chatbots.He also discusses the rise of AI-driven pentesting agents ("hack bots"), their current limitations, and how augmented human hackers will likely outperform them, at least for now. If you're wondering whether AI can really secure or attack itself, or how AI is quietly reshaping the bug bounty and AppSec landscape, this episode is a must-listen.Questions asked:(00:00) Introduction(02:14) A bit about Joseph(03:57) What is AI AppSec?(05:11) Components of AI AppSec(08:20) Bug Bounty for AI Systems(10:48) Common AI security issues(15:09) How will AI change pentesting?(20:23) How is the attacker landscape changing?(22:33) Where would autimation add the most value?(27:03) Is code being deployed less securely?(32:56) AI Red Teaming(39:21) MCP Security(42:13) Evolution of pentest with AIResources shared during the interview:- How to Hack AI Agents and Applications- Critical Thinking Bug Bounty Podcast - The Rise of AI Hackbots- Shift - Caido Plugin - Shadow Repeater- Nuclei - Haize Labs - White Circle AI- Prompt Injection Primer for Engineers

The Future of Digital Identity: Fighting AI Deepfakes & Identity Fraud
Can you prove you’re actually human? In a world of AI deepfakes, synthetic identities, and evolving cybersecurity threats, digital identity is more critical than ever.With AI-generated voices, fake videos, and evolving fraud tactics, the way we authenticate ourselves online is rapidly changing. So, what’s the future of digital identity? And how can you protect yourself in this new era?In this episode, hosts Caleb Sima and Ashish Rajan is joined by Adrian Ludwig, CISO at Tools For Humanity (World ID project), former Chief Trust Officer at Atlassian, and ex-Google security lead for Android. Together, they explore:Why digital identity is fundamentally broken and needs a major rebootThe rise of AI-powered identity fraud and how it threatens securityHow World ID is using blockchain and biometrics to verify real humansThe debate: Should we trust governments, companies, or decentralized systems with our identity?The impact of GenAI & deepfakes on authentication and online trustQuestions asked:(00:00) Introduction(03:55) Digital Identity in 2025(14:13) How has AI impacted Identity?(29:33) Trust and Transparency with AI(32:18) Authentication and Identity(49:53) What can people do today?(52:05) Where can people learn about World Foundation?(53:49) Adoption of new identity protocolsResources spoken about during the episode:Tools for HumanityWorld.org
