Episode 415 - Reducing attack surface for less security
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.

Episode 413 - PyTorch and NPM get attacked, but it's OK
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.

Episode 412 - Blame the users for bad passwords!
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.

Episode 410 - Package identifiers are really hard
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.

Episode 407 - Should Santa use AI?
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.

Episode 406 - The security of radio
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
Episode 405 - Modding games isn't cheating and security isn't fair
Josh and Kurt talk about Capcom claiming modding a game is akin to cheating. The arguments used are fundamentally one of equity vs equality. Humans love to focus on equality instead of equity when we deal with most problems. This is especially true in the world of security. Rather than doing something that has a net positive, we ignore the details and focus on doing something that feels "right". Show Notes Why Capcom thinks PC game modding is akin to “cheating” Ben Heck
Episode 403 - Does the government banning apps work?
Josh and Kurt talk about the Canadian Government banning WeChat and Kaspersky. There's a lot of weird little details in this conversation. It fundamentally comes down to a conversation about risk. It's easy to spout nonsense about risk, but having an honest discussion about it is REALLY complicated. But the government plays by a very different set of rules.

Episode 402 - The EU's eIDAS regulation is a terrible idea
Josh and Kurt talk about the new EU eIDAS regulation. This is a bill that will force web browsers to add root certificates based on law instead of technical merits, which is how it's currently done.
