MacOS Security Design Features, Flaws, And Futures - Patrick Wardle - ASW #392
Application Security Weekly (Audio)
Appsec often frames usability and security as at odds with each other. Apple's software has famously emphasized the importance of usability while also creating a solid security foundation. Patrick Wardle talks about how he's seen malware shift from Windows to macOS, how Apple's aggressive stance on deprecation benefits security, and the areas of the OS where he still sees plenty of opportunity for more security research. We discuss how developers make defensible design choices, why privacy needs security, and some security principles that any app developer should keep in mind regardless of...

Discovering & Securing Your AI Agent Attack Surface - Jeremy Snyder - ASW #391
Application Security Weekly (Audio)
While LLMs and agents are new to appsec and everyone else, a lot of AI security requirements translate to well-known API security requirements. Jeremy Snyder helps us frame the OWASP LLM Top 10 into five layers in order to help orgs understand and prioritize their attack surface. A lot of orgs don't have to deal with model-specific threats or building their own GPU architecture, but every org adopting LLMs and agents should be aware of how those agents are being invoked and the output those agents are producing. That awareness of input and output helps in identifying and mitigating prompt...

Defense-in-depth strategies for securing mobile applications - Ryan Lloyd - ASW #390
Application Security Weekly (Audio)
Mobile applications have unique risks and threat models compared to server-side applications and infrastructure. Consequently, they need different strategies to ensure their business logic and workflows well secured. We'll dive into some of these defense-in-depth strategies and why they are important to mobile applications. Securing workflows goes beyond input validation and pattern matching suspicious payloads; it requires detailed attention to state machines, edge cases, and collecting signals to evaluate trust.

Reducing Attack Surface & Evaluating Efficiency in Agents - Itamar Apelblat, David Goldschlag - ASW #389
Application Security Weekly (Audio)
SquidBleed reveals another vuln that's been lurking for decades, but its real lesson is in managing an attack surface. Regardless of whatever programming language you use, removing code is one of the best security steps you can take, followed by changing default configs to turn off uncommon features and ancient protocols. The Linux kernel's removal of strncpy is another example of managing attack surface by replacing a notoriously misused and ambiguous function with more specific versions that better match the developers intent. It was a six-year journey for the kernel, but one that should...

How AI Is Reshaping Identity Security at the Infrastructure Layer - Amit Masand, Neha Duggal, Ev Kontsevoy - ASW #388
Application Security Weekly (Audio)
Appsec has seen machine identities from daemons and processes to services, microservices, and cloud accounts. And now we have agents. Ev Kontsevoy talks about what it means to have engineers and agents interacting in an environment, and why a focus on actions can be more effective than roles. One of the biggest challenges in securing agents along with all of the other identities that organizations manage is how fragmented that management has become. But a unified engineering view of identities is just a start. Once you're able to shift to a practice where access is granted based on attributes...

Why Does It Matter Who or What Created the Code? - Matias Madou - ASW #387
Application Security Weekly (Audio)
Agents and LLMs are creating and reviewing code. They're a new tool to help developers write software and they're a new abstraction layer for expressing what code should do. But if we're focused on determining whether code is secure, where do we focus our attention on ensuring a secure outcome? Matias Madou talks about the challenges of finding metrics to help answer these questions. We walk through many of the questions we'd like to see answered and our desire to see appsec (finally?) shift out of a find-and-fix mode into a future of secure design.

Scanner Results Are a Starting Point. Here's What Comes Next. - Federico Kirschbaum - ASW #386
Application Security Weekly (Audio)
Most AppSec teams are working through more findings than their teams can validate. SAST surfaces thousands of potential issues. DAST generates alert volume that outpaces triage capacity. Somewhere in that output are the vulnerabilities that matter, the ones that are actually exploitable in production. This conversation explores why automated testing often stops short of the hardest part of the job: proving what is real. We dig into how business logic flaws and authorization vulnerabilities get missed by tools that scan without reasoning, what exploit validation looks like at runtime, and how...

BadHost, Dead CTFs, Exploding NPMs, and the Verizon DBIR - ASW #385
Application Security Weekly (Audio)
We dedicate an episode to catching up on appsec news with Kalyani Pawar. We see parsing problems that led to the BadHost vuln, which exposed lots of LLMs, MCPs, and agents to potential compromise. We wonder where to look for security education and practice as the camaraderie of the CTF community becomes infiltrated by LLMs. We talk about the tradeoffs in trust between using public packages vs. having agents write replacements from scratch. And we examine some of the appsec details that the Verizon DBIR reveals about how orgs are being attacked -- and how orgs might use that information to...

AppSec Conversations on Agents, LLMs, and OWASP from RSAC - Merritt Maxim, Scott Clinton, Janet Worthington - ASW #384
Application Security Weekly (Audio)
We showcase recordings from this year's RSAC. At RSAC Conference 2026, Scott Clinton, Co-Chair and co-founder of the OWASP GenAI Security Project, shares insights from the project’s latest research, including new landscape guides and evolving approaches to securing generative and agentic AI systems. The conversation explores critical gaps in GenAI data security, the rise of AI-assisted development, and the immense growth of the OWASP community and sponsor ecosystem. Looking ahead, he outlines the most urgent risks and priorities shaping AI and agentic security in 2026. Then Merritt Maxim...

The State of AI & AppSec - Keith Hoodlet - ASW #383
Application Security Weekly (Audio)
This year has been a dichotomy of established secure design fundamentals and burgeoning chaos of LLM-driven vuln discovery. Keith Hoodlet returns to share his latest observations on what the recent news about Mythos, models, and harnesses means for appsec. He walks through the problems of misalignment, the potential development doom that looms behind a volume of vulns, and what modern code creation looks like. Along the way we touch on the economics of tokens and the principles behind secure software. Keith gave a preview of his upcoming presentation (May 22nd) on these topics. Check out for...
info_outlineMongoBleed and a recent OWASP CRS bypass show how parsing problems remain a source of security flaws regardless of programming language. We talk with Kalyani Pawar about how these problems rank against the Top 25 CWEs for 2025 and what it means for relying on LLMs to generate code.
