Episode 453 - Software Liability 36:28

11d ago36:28

36:28

Josh and Kurt talk about three government activities happening around security. CISA has a request for comment, and an international strategic plan around cybersecurity.

1M ago39:01

39:01

Josh and Kurt talk about the current Wordpress / WP Engine mess. In what is certainly a supply chain attack, the Advanced Custom Fields forking. This whole saga is weird and filled with chaos and stupidity. We have no idea how it will end, but we do know that the blog platform you use shouldn't be this exciting. The bad sort of exciting.

Episode 449 - The CUPSpocalypse 38:01

1M ago38:01

38:01

Josh and Kurt talk about the recent CUPS issue. The vulnerability itself wasn't all that exciting, but the whole disclosure process was wild. There's a lot to talk about, many things didn't quite go as planned and it all leaked early. Let's talk about why and what it all means. Show Notes CUPS vulnerability Akamai report Wil Wheaton: being a nerd i…

Episode 448 - What's wrong with CISA? 34:48

2M ago34:48

34:48

Josh and Kurt talk about a few things that have recently come out of CISA. They seem to be blaming the vendors for a lot of the problems, but there's also not any actionable advice telling the vendors what they should be doing. This feels like the classic case of "just security harder". We need CISA to be leading the way funding and defining securi…

Episode 447 - The Tidelift 2024 open source maintainer report 38:52

2M ago38:52

38:52

Josh and Kurt talk about the 2024 Tidelift maintainer report. The report is pretty big and covers a ton of ground. We focus in a few of the statistics that should worry anyone who uses open source. We've known for a while developers are struggling, and the numbers back that up. This one feels like the old "we've tried nothing and we're all out of i…

Episode 446 - Researchers took over .MOBI TLD 33:06

2M ago33:06

33:06

Josh and Kurt talk about some security researchers sort of taking over the .MOBI whois server. The story is a bit sensational, but we ask if it really matters? There are a lot of interesting possible attacks, but turning something like this into a good attack is really hard, maybe impossible. The researchers presented the findings in a very reasona…

Episode 444 - Open Source and End of Life 37:49

2M ago37:49

37:49

Josh and Kurt talk about Chrome unexpectedly going EOL on Ubuntu 18. Keeping old things alive is really hard to do, and in open source it's becoming more common to just run the latest version rather than trying to keep old versions alive for long periods of time. Show Notes Chrome dumped support for Ubuntu 18.04 – but it'll be back Linus Torvalds t…

Episode 443 - The Supply Chain Security Crisis 34:23

3M ago34:23

34:23

Josh and Kurt talk about a story that discusses a story from Black Hat that references supply chains. There's a ton of doom and gloom around our software supply chains and much of the advice isn't realistic. If we want to take this seriously we need to stop obsessing over the little problems and focus on some big problems. Show Notes Black Hat USA …

Episode 442 - The foundation of society, TLS certificates are a mess 40:35

3M ago40:35

40:35

Josh and Kurt talk about a few stories around the TLS CA certificate world. It's all pretty dire sounding. There's not a lot of organization or process in the space, and the root CAs are literally the foundation of modern society, everything needs them to function.

Episode 440 - "What is open source" talk Josh gave 34:36

3M ago34:36

34:36

Josh and Kurt talk about a presentation Josh recently gave that was supposed to be about how open source works. The talk was the wrong topic for a security crowd, but there's a lot of interesting details in the questions and comments that emerged. It's clear a lot of security people don't really care about the fine details about what open source is…

Episode 439 - Where are all the youth in open source? 29:27

4M ago29:27

29:27

Josh and Kurt talk about a story talking about the "graying" of open source. There doesn't seem to be many young people working on open source, but we don't really know why that is. There are many thoughts, but a better question is why should anyone get involved in open source anymore? The world has changed quite a lot since open source was created…

Episode 438 - CISA's bad OSS advice vs the Whitehouse good advice 34:52

4M ago34:52

34:52

Josh and Kurt talk about two documents from the US government that discuss open source in very different ways. The CISA document lays out a way to measure open source, but we take issue with the idea of trying to measure which open source projects are "good". The Whitehouse on the other hand takes an approach that is very open source, get involved.…

Josh and Kurt talk about the recent OpenSSH vulnerability and the node-ip project owner taking their project private. They're quasi related in the context of two open source projects handled bugs very differently. The OpenSSH bug isn't really as serious as it seems, but you still want to patch.

Josh and Kurt talk about the latest polyfill.io mess. Apparently someone took over a very popular project and started to serve malware. First XZ, now this. What does it mean for open source? We don't have any answers, and it's hard to even talk about this problem because it's so big. The thing is though, even if we can't fix open source, it's here …

31:17

Josh and Kurt talk about three wangles of responsibility. We start with a story about a bike theft ring, bike theft doesn't usually get any attention, but this one is special.

Episode 433 - Should OpenSSH block misbehaving clients? 31:40

5M ago31:40

31:40

Josh and Kurt talk about a new proposal from OpenSSH to add a timeout to penalize clients misbehaving. But this then brings up the typical security conversation of "if it's not perfect we shouldn't do it". Trying new things is a good thing, even if something fails, we learn a lesson that we can use in the future. Show Notes OpenSSH introduces optio…

Josh and Kurt talk about a paper describing using a LLM to automatically create exploits for CVEs. The idea is probably already happening in many spaces such as pen testing and intelligence services. We can't keep up with the number of vulnerabilities we have, there's no way we can possibly keep up with a glut of LLM generated vulnerabilities. We r…

Josh and Kurt talk about a Notepad++ fake website. It's possibly not illegal, but it's certainly ethically wrong. We also end up discussing why it seems like all these weird and wild things keep happening. It's probably due to the massive size of open source (and everything) now. Things have gotten gigantic and we didn't really notice. Show Notes H…
