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 Help us to take down the parasite website Open Source is bigger than you can imagine Toronto Pearson International Airport heist
Josh and Kurt talk about a new FCC program to provide a cybersecurity certification mark. Similar to other consumer safety marks such as UL or CE. We also tie this conversation into GrapheneOS, and what trying to claim a consumer device is secure really means. Some of our compute devices have an infinite number of possible states. It's a really weird and hard problem. Show Notes GrapheneOS FCC approves cybersecurity label for consumer devices Cyber Trust Mark Logo
Josh and Kurt talk about the recent events around XZ. It's only been a few days, and it's amazing what we already know. We explain a lot of the basics we currently know with the attitude much of these details will change quickly over the coming week. We can't fix this problem as it stands, we don't know where to start yet. But that's not a reason to lose hope. We can fix this if we want to, but it won't be flashy, it'll be hard work. Show Notes GossiTheDog's Blog Post fr0gger diagram OpenSSF Blog (archive) stb library
Josh and Kurt talk about the security.txt file. It's not new, but it's not something we've discussed before. It's a great idea, an easy format, and well defined. It's not high on many of our todo lists, but it's something worth doing. Show Notes RFC 9116
Josh and Kurt talk about the new SSDF attestation form from CISA. The current form isn't very complicated, and the SSDF has a lot of room for interpretation. But this is the start of something big. It's going to take a long time to see big changes in supply chain security, but we're confident they will come. Show Notes Secure Software Development Attestation Form The U.S. Military Is Missing Six Nuclear Weapons NIST 800-218
Josh and Kurt talk about what's going on at the National Vulnerability Database. NVD suddenly stopped enriching vulnerabilities, and it's sent shock-waves through the vulnerability management space. While there are many unknowns right now, the one thing we can count on is things won't go back to the way they were. Show Notes Anchore's Blog Grype Josh's Cyphercon Talk Ecosyste.ms Episode 266 – The future of security scanning with Debricked
Josh and Kurt talk about an attack against GitHub where attackers are creating malicious repositories then artificially inflating the number of stars and forks. This is really a discussion about how can we try to find signal in all the noise of a massive ecosystem like GitHub. Show Notes GitHub besieged by millions of malicious repositories in ongoing attack
Josh and Kurt talk about recent stories about data breaches, flipper zero banning, and realistic security. We have a lot of weird challenges in the world of security, but hard problems aren't impossible problems. Sometimes we forget that. Show Notes Mon Dieu! Nearly half the French population have data nabbed in massive breach Feds move to ban auto theft tech device ‘Flipper Zero’ Gmail and Yahoo’s 2024 inbox protections and what they mean for your email program Vending machine error reveals secret face image database of college students
Josh and Kurt talk to GregKH about Linux Kernel security. We most focus on the topic of vulnerabilities in the Linux Kernel, and what being a CNA will mean for the future of Linux Kernel security vulnerabilities. The future of Linux Kernel security vulnerabilities is going to be very interesting. Show Notes Greg K-H Linux Kernel is a CNA Machine learning and stable kernels Bug reporting for Linux
Josh and Kurt talk to Thomas Depierre about some of the European efforts to secure software. We touch on the CRA, MDA, FOSDEM, and more. As expected Thomas drops a huge amount of knowledge on what's happening in open source. We close the show with a lot of ideas around how to move the needle for open source. It's not easy, but it is possible. Show Notes Thomas Depierre I am not a supplier Open Source In The European Legislative Landscape devroom Cyber Resilience Act The 2023 Tidelift state of the open source maintainer report
Josh and Kurt talk about a blog post explaining how to create a very very small container image. Generally in the world of security less is more, but it's possible to remove too much. A lot of today's security tooling relies on certain things to exist in a container image, if we remove them we could actually result in worse security than leaving it in. It's a weird topic, but probably pretty important. Show Notes How I reduced the size of my very first published docker image by 40% - A lesson in dockerizing shell scripts Hacker News Discussion Episode 293 – Scoring OpenSSF Security Scoring
Josh and Kurt talk about open source projects proving builds, and things nobody wants to pay for in open source. It's easy to have unrealistic expectations for open source projects, but we have the open source capitalism demands. Show Notes Open Source Doesn't Require Providing Builds The things nobody wants to pay for Audacity privacy policy update has caused an outcry The History of X11
Josh and Kurt talk about an attack against PyTorch and NPM. The PyTorch attack shows the difficulty of trying to operate a large open source project. The NPM problem is one of the difficulty in trying to backdoor open source. A lot of people are watching and it only takes one person to notice a problem and we all benefit. Show Notes Peanut Butter the dog plays Gyromite The Wizard movie PyTorch supply chain attack npm Package Found Delivering Sophisticated RAT Deceptive Deprecation: The Truth About npm Deprecated Packages Changing a lightbulb Spelunking the Bitcoin Blockchain with Josh Bressers | CypherCon 4.0 Operation Triangulation - What You Get When Attack iPhones of Researchers 9th Annual State of the Software Supply Chain
Josh and Kurt talk about the 23andMe compromise and how they are blaming the users. It's obviously the the fault of the users, but there's still a lot of things to discuss on this one. Every company has to care about cybersecurity now, even if they don't want to. Show Notes Security leaders weigh in on 23andme hack Don't need a gun when you have a Donk - Crocodile Dundee 2 Hackers can infect network-connected wrenches to install ransomware My disappointment is immeasurable, and my day is ruined
Josh and Kurt talk about a grab bag of old technologies that defined the security industry. Technology like SELinux, SSH, Snort, ModSecurity and more all started with humble beginnings, and many of them created new security industries. Show Notes SELinux AppArmor SSH ModSecurity Snort Nmap Nessus What comes after open source
Josh and Kurt talk about package identifiers. We break this down in the context of an OpenSSF response to a CISA paper on software identifications. The identifiers that get all the air time are purl, CPE, SWID, and OmniBOR. This is a surprisingly complex problem space. It feels easy, but it's not. Show Notes OpenSSF CISA response purl CPE OmniBOR SWID
Josh and Kurt talk about how some hackers saved the day with a Polish train. We delve into a discussion about how we don't really own anything anymore if you look around. There's a great talk from the Blender Conference about this and how GPL makes a difference in the world of software ownership. It's sort of a dire conversation, but not all hope is lost. Show Notes Polish manufacturer accused of programming failures into its trains to gain more servicing business Polish Hackers Repaired Trains the Manufacturer Artificially Bricked. Now The Train Company Is Threatening Them Blender Conference Keynote Corey Doctorow Chicago has a problem until the year 2083 | Stand-up Maths Chicago Doesn’t Own Its Own Streets | Climate Town
Josh and Kurt talk about a story asking for a Kubernetes LTS. Should open source projects have LTS versions? What does LTS even mean? Why is maintaining software so hard? It's a lively discussion all about the past, present, and future of open source LTS. Show Notes Why Kubernetes needs an LTS Linux gives up on 6-year LTS kernels, says they’re too much work
It's the 2023 Christmas Spectacular! Josh and Kurt talk about what would happen if Santa starts using AI to judge which children are naughty and nice. There's some fun in this one, but it does get pretty real. While we tried to discuss Santa using AI, the reality is this sort of AI is coming for many of us. AI will be making decisions for all of us in the near future (if it isn't already). While less fun than we had hoped for, it's an important conversation. Show Notes Sea Elf Ollama UnitedHealth uses faulty AI to deny elderly patients medically necessary coverage, lawsuit claims Stephen Fry on AI Lawyer who cited cases concocted by AI asks judge to spare sanctions Hugging Face
Josh and Kurt talk about a few security stories about radio. The TETRA:BURST attack on police radios, spoofing GPS for airplanes near Iran, and Apple including cellular radios in the macbooks. The common thread between all these stories is looking at the return on investment for security. Sometimes good enough security is fine, sometimes it's not worth fixing certain security problems because the risk vs reward doesn't work out. Show Notes TETRA:BURST GPS spoofing attack Apple MacBooks cellular radio Mossad vs Not Mossad
