What happens when a QR code leads to a major security incident? In this episode, Amy sits down with Senior Incident Response Consultant Terryn Valikodath to break down a recent, high-stakes breach at an Australian medical center. Attackers are ditching traditional malware for "cloud-native" tactics — using personalized QR code phishing to bypass corporate defenses and operate entirely within the cloud. Beyond the technical details, Amy and Terryn chat about the pressure of defending environments where patient care is on the line and why a blameless culture is a great defense. Take a listen for some practical, down-to-earth advice on how to audit your own logs and keep your team prepared for when things go sideways. Talos IR Trends Q2 2026: https://blog.talosintelligence.com/ir-trends-q2-2026/

In this episode, Amy and analyst Lexi DiScola unpack the trends Talos IR saw on the frontlines in Q2 2026. From creative phishing lures that slip past email gateways to the weaponization of legitimate remote management tools, we explore why traditional defenses are falling short and the practical things you can do to reclaim the advantage. What configuration changes and visibility gaps could be the difference between a minor incident and a full-scale breach? How can you harden your environment with limited resources? Tune into this episode to stay one step ahead of an evolving threat landscape.

MFA and password resets aren't always enough. That’s terrifying for security teams today. In this episode of Talos Takes, we dive deep into ARToken, a sophisticated phishing/BEC-as-a-service platform that steals credentials, bypasses MFA entirely, and leverages primary refresh tokens (PRTs) to maintain persistence in your environment long after a password reset. This turns a simple phishing click into a long-term breach. It’s time to rethink your defenses. Join us as Cisco Talos Threat Researcher Michael Kelley breaks down how this new breed of automated attack works and, more importantly, how you can spot it. From hunting for suspicious device authorization grants to securing your cloud infrastructure, don't miss this critical look at the new frontier of business email compromise.

While the Component Object Model (COM) is a fundamental Windows technology that allows software to communicate and function, it's also a powerful tool for threat actors looking to move laterally, maintain persistence, and evade traditional security measures. Joining us is Vanya Svajcer, who shares his expertise on how to cut through the noise and identify malicious signals within COM-based binaries. Whether you are a seasoned researcher or just starting your journey into reverse engineering and malware analysis, here's some practical advice on how to start hunting for COM-based threats and making your next investigation a little more effective.

If you're tired of being told to "just patch," we understand. The threat landscape is evolving at breakneck speed, with AI-driven tools enabling adversaries to uncover and exploit vulnerabilities before defenders even know they exist. In this episode of Talos Takes, Amy sits down with Threat Intelligence Lead Pierre Cadieux to discuss how to defend against these unknown threats. We move past the simplified advice of "just patch everything" to explore the logistical, technical, and business realities that make patching a complex, high-stakes operation rather than a simple button click. From the necessity of testing your patches to the importance of building strong partnerships between security teams and business leadership, this episode breaks down the things defenders often miss that build true resilience in organizations.

Are your detection rules failing because your test data lacks the nuance of a real-world network? In this episode of Talos Takes, Amy sits down with David Bianco to discuss why traditional synthetic data often falls short and how his new open-source project, EvidenceForge, is changing the game. Synthetic datasets often look like telemetry but lack the critical causal links and realistic background noise that define actual adversary activity. EvidenceForge solves this by creating data that tells a coherent, causal story. From simulating complex attack chains to modeling realistic, "bursty" human behavior, this tool helps threat hunters and detection engineers to sharpen their skills with reproducible, high-quality telemetry.

In this episode of Talos Takes, Amy Ciminnisi sits down with researcher Diana Brown to discuss the rise of "platform-as-a-proxy" (PAP) attacks. We explore how threat actors are weaponizing legitimate SaaS platforms like GitHub and Jira to deliver phishing campaigns that bypass traditional security filters. By leveraging the platforms' own infrastructure to send authenticated emails, attackers are exploiting the inherent trust employees place in these essential business tools. We break down the mechanics of these campaigns and provide actionable strategies for security teams to move beyond binary trust and implement contextual awareness to better protect their organizations.

In this episode, we unpack state-sponsored and phishing trends from the 2025 Talos Year in Review. Amy and Martin Lee explore the alarming rise of internal phishing campaigns that bypass traditional perimeter defenses, including the widespread weaponization of Microsoft 365's Direct Send feature. Beyond simple phishing, we analyze the aggressive, blended operations of state-sponsored actors from China and North Korea who are combining high-level zero-day exploits with sophisticated social engineering. From the "Dear Leader" interview test to the reality of fake developer personas, we break down exactly how these adversaries are infiltrating modern organizations. 2025 Year in Review report: https://blog.talosintelligence.com/2025yearinreview/

In this episode, Amy and Pierre Cadieux unpack the ransomware and vulnerability trends that defined 2025. From the persistent ransomware threats targeting the manufacturing sector to the rise of stealthy "living off the land" tactics, we break down what these shifts mean for your defense strategy. Why are attackers are increasingly targeting your management infrastructure? How do you spot the difference between a system admin and a threat actor? Tune in to hear Talos' insights on how to move beyond reacting to threats and start building a more resilient, proactive security posture for the year ahead.
