We look into the supply chain saga of the XZ Utils backdoor. It's a wild story of a carefully planned long con to add malicious code to a commonly used package that many SSH connections rely on. It hits themes from social engineering and abuse of trust to obscuring the changes and suppressing warnings. It also has a few lessons about software development, the social and economic dynamics of open source, and strategies for patching software. It's an exciting topic partially because so much other appsec is boring. And that boring stuff is important to get right first. We also talk about what parts of this that orgs should be worried about and what types of threats they should be prioritizing instead.

In this discussion, we focus on vendor/tool challenges in infosec, from a security leader's perspective. To quote our guest, Ross, "running a security program is often confused with shopping". You can't buy an effective security program any more than you can buy respect, or a black belt in kung fu (there might be holes in these examples, but you hopefully get the point). In fact, buying too much can often create more problems than it solves, especially if you're struggling to fill your staffing needs. In part 2 of this 2-part episode, we'll discuss: - The pros and cons of buying from different types of companies - Who to look to for product recommendations - Is making a plan to "ditch before you hitch" a good or bad idea? - What to do when you inherit a mess Show Notes: https://securityweekly.com/bsw-345

As we near RSA conference season, tons of security startups are coming out of stealth! The RSA Innovation Sandbox has also announced the top 10 finalists, also highlighting early stage startups that will be at the show. In this week's news segment, We discuss the highlights of the Cyber Safety Review Board's detailed and scathing report on Microsoft's 2023 breach We spend a bit of time on the xz backdoor, but not too much, as it has been covered comprehensively elsewhere We discover half a dozen of the latest startups to receive funding or come out of stealth: Coro, Skyflow, Zafran, Permiso, Bedrock Security, Abstract Security, and Sandfly Apple is reportedly going to have some big AI announcements this summer, and we discuss how overdue voice assistants are for an LLM makeover. Finally, we discuss the amazing innovation that is the Volkswagen RooBadge! By the way, the thumbnail is a reference to the xz backdoor link we include in the show notes: https://lcamtuf.substack.com/p/technologist-vs-spy-the-xz-backdoor Show Notes: https://securityweekly.com/esw-356

NVD checked out, then they came back? Maybe? Should the xz backdoor be treated as a vulnerability? Is scan-driven vulnerability management obsolete when it comes to alerting on emerging threats? What were some of the takeaways from the first-ever VulnCon? EPSS is featured in over 100 security products, but is it properly supported by those that benefit from it? How long do defenders have from the moment a vulnerability is disclosed to patch or mitigate it before working exploits are ready and in the wild? There's SO much going on in the vulnerability management space, but we'll try to get to the bottom of some of in in this episode. In this interview, we talk to Patrick Garrity about the messy state of vulnerability management and how to get it back on the rails.
