Application Security Weekly (Video)

Pull requests are a core part of collaboration, whether in open or closed source. GitHub has documented some of the security consequences of misconfiguring how PRs can trigger actions. But what happens when repo owners don't read the docs? Bar Kaduri and Roi Nisimi walk through their experience in reading docs, finding vulns, demonstrating exploits, and working with repo owners to improve their se...

The post quantum encryption migration is going to be a challenge, but how much of a challenge? There are several reasons why it is different from every other protocol and cypher iteration in the past. Is today's hardware up to the task? Is it just swapping out a library, or is there more to it? What is the extent of software, systems, and architecture that have to be updated or replaced to complet...

Ransomware attacks typically don't care about memory safety and dependency scanning, they often target old, unpatched vulns and too often they succeed. Rob Allen shares some of the biggest cases he's seen, what they have in common, and what appsec teams could do better to help them. Too much software still requires custom configuration to make it more secure. And too few software makers are embrac...

Interest and participation in the OWASP GenAI Security Project has exploded over the last two years. Steve Wilson explains why it was important for the project to grow beyond just a Top Ten list and address more audiences than just developers. He also talks about how the growth of AI Agents influences the areas that appsec teams need to focus on. Whether apps are created by genAI or directly use g...

Software has forever had flaws and humans have forever been finding and fixing them. With LLMs generating code, appsec has also been trying to determine how well LLMs can find flaws. Nico Waisman talks about XBOW's LLM-based pentesting, how it climbed a bug bounty leaderboard, how it uses feedback loops for better pentests, and how they handle (and even welcome!) hallucinations. In the news, using...

Dealing with vulns tends to be a discussion about prioritization. After all, there a tons of CVEs and dependencies with known vulns. It's important to figure out how to present developers with useful vuln info that doesn't overwhelm them. Francesco Cipollone shares how to redirect that discussion to focus on remediation and how to incorporate LLMs into this process without losing your focus or los...

In the news, Microsoft encounters a new cascade of avoidable errors with Entra ID, Apple improves iOS with hardware-backed memory safety, DeepSeek demonstrates the difficulty in reviewing models, curl reduces risk by eliminating code, preserving the context of code reviews, and more!

This week, we chat with Scott Clinton, board member and co-chain of the OWASP GenAI Security Project. This project has become a massive organization within OWASP with hundreds of volunteers and thousands of contributors. This team has been cranking out new tools, reports and guidance for practitioners month after month for over a year now. We start off discussing how Scott and other leaders have m...

Up first, the ASW news of the week. At Black Hat 2025, Doug White interviews Ted Shorter, CTO of Keyfactor, about the quantum revolution already knocking on cybersecurity's door. They discuss the terrifying reality of quantum computing's power to break RSA and ECC encryption—the very foundations of modern digital life. With 2030 set as the deadline for transitioning away from legacy crypto, organi...

In this must-see BlackHat 2025 interview, Doug White sits down with Michael Callahan, CMO at Salt Security, for a high-stakes conversation about Agentic AI, Model Context Protocol (MCP) servers, and the massive API security risks reshaping the cyber landscape. Broadcast live from the CyberRisk TV studio at Mandalay Bay, Las Vegas, the discussion pulls back the curtain on how autonomous AI agents a...

The EU Cyber Resilience Act joins the long list of regulations intended to improve the security of software delivered to users. Emily Fox and Roman Zhukov share their experience education regulators on open source software and educating open source projects on security. They talk about creating a baseline for security that addresses technical items, maintaining projects, and supporting project own...

A smaller attack surface should lead to a smaller list of CVEs to track, which in turn should lead to a smaller set of vulns that you should care about. But in practice, keeping something like a container image small has a lot of challenges in terms of what should be considered minimal. Neil Carpenter shares advice and anecdotes on what it takes to refine a container image and to change an org's e...

Open source software is a massive contribution that provides everything from foundational frameworks to tiny single-purpose libraries. We walk through the dimensions of trust and provenance in the software supply chain with Janet Worthington. And we discuss how even with new code generated by LLMs and new terms like slopsquatting, a lot of the most effective solutions are old techniques. Resources...

Maintaining code is a lot more than keeping dependencies up to date. It involved everything from keeping old code running to changing frameworks to even changing implementation languages. Jonathan Schneider talks about the engineering considerations of refactoring and rewriting code, why code maintenance is important to appsec, and how to build confidence that adding automation to a migration resu...

A successful strategy in appsec is to build platforms with defaults and designs that ease the burden of security choices for developers. But there's an important difference between expecting (or requiring!) developers to use a platform and building a platform that developers embrace. Julia Knecht shares her experience in building platforms with an attention to developer needs, developer experience...

AI is more than LLMs. Machine learning algorithms have been part of infosec solutions for a long time. For appsec practitioners, a key concern is always going to be how to evaluate the security of software or a system. In some cases, it doesn't matter if a human or an LLM generated code -- the code needs to be reviewed for common flaws and design problems. But the creation of MCP servers and LLM-b...

What are some appsec basics? There's no monolithic appsec role. Broadly speaking, appsec tends to branch into engineering or compliance paths, each with different areas of focus despite having shared vocabularies and the (hopefully!) shared goal of protecting software, data, and users. The better question is, "What do you want to secure?" We discuss the Cybersecurity Skills Framework put together...

Appsec still deals with ancient vulns like SQL injection and XSS. And now LLMs are generating code along side humans. Sandy Carielli and Janet Worthington join us once again to discuss what all this new code means for appsec practices. On a positive note, the prevalence of those ancient vulns seems to be diminishing, but the rising use of LLMs is expanding a new (but not very different) attack sur...

Manual secure code reviews can be tedious and time intensive if you're just going through checklists. There's plenty of room for linters and compilers and all the grep-like tools to find flaws. Louis Nyffenegger describes the steps of a successful code review process. It's a process that starts with understanding code, which can even benefit from an LLM assistant, and then applies that understandi...

Fuzzing has been one of the most successful ways to improve software quality. And it demonstrates how improving software quality improves security. Artur Cygan shares his experience in building and applying fuzzers to barcode scanners, smart contracts, and just about any code you can imagine. We go through the useful relationship between unit tests and fuzzing coverage, nudging fuzzers into deeper...

What makes a threat modeling process effective? Do you need a long list of threat actors? Do you need a long list of terms? What about a short list like STRIDE? Has an effective process ever come out of a list? Farshad Abasi joins our discussion as we explain why the answer to most of those questions is No and describe the kinds of approaches that are more conducive to useful threat models. Resour...

CISA has been championing Secure by Design principles. Many of the principles are universal, like adopting MFA and having opinionated defaults that reduce the need for hardening guides. Matthew Rogers talks about how the approach to Secure by Design has to be tailored for Operational Technology (OT) systems. These systems have strict requirements on safety and many of them rely on protocols that a...

The recent popularity of MCPs is surpassed only by the recent examples deficiencies of their secure design. The most obvious challenge is how MCPs, and many more general LLM use cases, have erased two decades of security principles behind separating code and data. We take a look at how developers are using LLMs to generate code and continue our search for where LLMs are providing value to appsec....

ArmorCode unveils Anya—the first agentic AI virtual security champion designed specifically for AppSec and product security teams. Anya brings together conversation and context to help AppSec, developers and security teams cut through the noise, prioritize risks, and make faster, smarter decisions across code, cloud, and infrastructure. Built into the ArmorCode ASPM Platform and backed by 25B find...

In the news, Coinbase deals with bribes and insider threat, the NCSC notes the cross-cutting problem of incentivizing secure design, we cover some research that notes the multitude of definitions for secure design, and discuss the new Cybersecurity Skills Framework from the OpenSSF and Linux Foundation. Then we share two more sponsored interviews from this year's RSAC Conference. With more types o...
