November turned the podcast to a film noir narrative.

The Case of the Greedy Characters (ep. 262)

A lot of appsec conferences have presentations for appsec audiences -- but that's not often the group that's building apps. What if more developer conferences had #appsec content? We talked with Josh Goldberg, an Open Source developer, about security from the developer's point of view, both as an audience hearing about it and as a presenter talking about it. We discussed the importance of knowing your audience and finding the hooks in security tools and topics that resonate with developers.

The Case of the Menacing Slash (ep. 263)

We had another repeat guest with Karl Triebes, who talked about what 2023 brought to appsec and what appsec teams can bring to 2024. Several of the headline-grabbing attacks were old-school flaws, but that’s also because there’s a lot of legacy code out there. Other attacks were bots doing things users do – just at a bigger scale. In other words, attacks based on scraping and scalping and credential stuffing had nothing to do with input validation. They were all about finding workflows that benefited the attackers, whether an account takeover or hoarding concert tickets.

Shrug & Move On (ep. 160, replay)

The month’s third episode took us to the vault for an episode from August 2021 where Maggie Jauregi talked about firmware security. She shared tips on getting into hardware and firmware security on a small budget – something that can broaden the community of researchers in this area. She talked about that community and how welcoming it’s been. Hacking is a creative endeavor and it’s fun to interact with physical devices, whether it’s triggering a glitch with walkie talkies like in her first DEF CON presentation or playing with Raspberry PI and Arduinos.

The Case of the Race Condition (ep. 264)

We ended the month with a conversation on starting things – like starting an appsec program and starting an appsec career. Akira and John shared their questions and insights on how to decide when to specialize, when a startup might consider hiring for an appsec role, and how to figure out if you want that role to take on more engineering or more security testing responsibilities. While there was an unspoken theme of maturity models, there was quite a fun theme of music and being a virtuoso!

October was the month when tales of terror were timely and horror marked our days to Halloween.

Creating Presentations and Training That Engage an Audience (ep. 257)

We started with a topic that instills fear into everyone at some point – public speaking. Lina Lau returned to give us examples of how she crafts and delivers presentations. We talk about what kinds of presentations keep our attention and the kinds that put us to sleep. Not only does Lina excel at delivering engaging presentations, she puts those skills to work in creating multi-day training courses for incident responders.

Lina first joined us back in February of this year to give an incident responder’s view of appsec. Check out episode 230.

Don't Fear the Repo (ep. 258)

Our second week brought another returning guest, Janet Worthington. She covered the conversations she’s had with developers and appsec teams about tools like SCA and SAST. More importantly, she highlighted that how those tools are used is really a side-effect of a good DevSecOps program. Trust and the “no look pass” is one part of a good program. Seeing DevSecOps teams focus their attention on design – securing what they sell – is a much better indicator of success than forever focusing on finding and fixing flaws.

It was just over a year ago that Janet joined us to talk about appsec education in universities. Check out episode 213.

Scary Stories (ep. 259)

Week three was OT. Huxley Barbee gave us some background on how insecure OT devices have been in the last few decades. But we also turned to what might help OT devices be more secure for the next few decades. It’s still hard to emulate and test many of these systems, which limits the amount of security researchers that take the time to understand and test them. It’s also still hard to find development toolchains that provide robust security feedback and testing. We’ve seen great improvements for C and C++ code with features like LLVM’s sanitizers. Hopefully we’ll see those and more applied to these OT devices as well.

Jump Scares (ep. 260)

Then Dan Moore returned to talk about the secure by design and secure by default aspects of OAuth and WebAuthn. I was curious about how OAuth added more capabilities and extensions to deal with new design patterns like single-page apps and the proliferation of mobile apps. The two standards aren't directly comparable in terms of problems they solve, but they share many goals in making adoption easier by developers and countering certain threats to users. There’s also a lesson in what they don’t cover, like account recovery, and why that remains an area that attackers continue to successfully exploit.

Camp Crystal Lake Breach Notification (ep. 261)

Our show just before Halloween covered an appropriately scary topic – how security tools must evolve. Dan Kuykendall talked about the struggle of scanners to keep up with modern app designs and why being beholden to industry categories isn’t providing modern dev teams with the solutions they need. That took us into dev leadership and how to inspire security teams to build effective tools.

I mostly don't care about known vulns in dependencies. I appreciate code quality and want to maintain a recency of at least 1-2 semver minor versions for packages. But so many of those vulns are distractions that don't require prioritization over normal maintenance -- things like XSS in unused code paths, reDoS, malicious config files, and exploit scenarios that require the planets to align in a great conjunction.

I'd rather know about one version to upgrade to than a list of security issues with questionable impact whose remediation spans a range of versions. I also wish scanners would roll up findings into a single "apply this patch" recommendation.

What I wish existed was a scaleable, well-supported scanner that enumerated all runtime dependencies and let me define alerting rules based on:

• the distance from the most recent semver minor version
• the distance from the most recent semver major version
• the days since that most recent major/minor version
• the days until a known EOL such as tracked in endoflife.date

Then for the dimension of known vulns I'd prioritize the CISA KEV along with malicious packages, i.e. packages delivered from a trusted source, but whose contents have been compromised. For the latter, think of packages obtained from trusted package repos, such as XZ Utils or an NPM package that included a malicious commit.

Yes, not every package follows a clean semver, but I'd love to bury the patch-all-the-vulns mentality that comes from being able to identify every single CVE in existence and instead raise a regular maintenance routine that accommodates the meaningful vulns.

We can even keep the SCA tool category -- just call it Semver Creation Analysis or maybe Semver Curation Approach instead. ;)

September was the month we hit our 8-bit milestone on [Application Security Weekly].

Big Smiles (ep. 179, replay)

The first week we went to the vault for an episode from January 2022 where Christien Rioux talked about how appsec needs to move beyond its past -- vulns, checklists, hardening guides -- and into a future of sandboxed apps and decorated data.

The Case of the Sensitive Info (ep. 254)

Then we talked with Simon Bennetts about how and why he started ZAP. As a long-time fan of the project, I enjoyed learning more about its past (it's been decades since I last heard mention of Paros Proxy!) and, more importantly, to hear about its future with The Software Security Project.

One of the takeaways that I didn't emphasize enough was Simon's outreach and interaction with developers -- we need more appsec folks speaking at developer conferences.

Leaving 8 Bits Behind (ep. 255)

Next up was Karl Triebes, who gave us a chance to go beyond the all-too-vague label of "business logic" attacks to understand why they're hard to pin down -- by appsec team and developers alike. For me, that's where the real interesting security flaws are, where human creativity can look at the workflow intended by an app and then come up with ways to abuse it.

Double the Byte! (ep. 256)

Last up was a return to supply chains with Kirsten Newcomer. The SBOMs have been around for a while -- SPDX is over a decade old. Which makes it seem like there are so many things that we need to do that aren't new. But that's probably also because they're not easy to do and, I think, because appsec gets too wrapped up in vulns and the cliche of fixing vulns early at the expense of spending time on more strategic work.

August brought some sun from the summer conferences and some darkness from some noir-style intros.

Case Files of the AppSec Detective (ep. 250)

Our first interview was with Merritt Baer, who put ArchSec – Architecture Security – on our roadmap. One of my favorite things about this discussion was the idea of getting beyond appsec, especially the stale, boring version of appsec that’s preoccupied with vulns. ArchSec represents a step towards making security scale better by focusing on design. She also points out how a secure architecture process isn’t just another security review in disguise, it’s a partnership in creating resilient systems.

Pointers & Perils for Presentations (ep. 251)

The second week was one of the longer (maybe longest) interviews we’ve recorded. Josh Goldberg talked about communication skills, putting together presentations, and the stumbles he’s made along the way. It’s a topic that should appeal to anyone who wants to speak at conferences – or even just giving presentations at work.

No one wants to sit through a boring presentation. No one wants to deliver a boring presentation, either! Josh shares tips and techniques for creating abstracts for CFPs and drafting slides for success. John Kinsella helped round out the segment with several stories and advice of his own.

The Case of Secure By Design (ep. 252)

For week three we ran two shorter interviews recorded at BlackHat. Shout out to Mandy Logan for conducting these at the conference.

But don’t skip our news segment – I kicked off the show with another dash of noir.

The Case of the Poisoned Model (ep. 253)

August closed with a visit from Jeff Pollard to cover how security can be smart about using AI. No cliches here about Skynet or magical thinking about robot overlords, just a lot of discussion about what AI and ML seems to be good at, where that helps security teams, and where people remain key parts of processes.
