In the days when Mirai emerged and took down DynDNS, along with what seemed like half the Internet, DDoS was as active a topic in the headlines as it was behind the scenes (check out Andy Greenberg's amazing story on Mirai on Wired). We don't hear about DDoS attacks as much anymore. What happened? Well, they didn't go away. DDoS attacks are a more common and varied tool of cybercriminals than ever. Today, Michael Smith is going to catch us up on the state of DDoS attacks in 2024, and we'll focus particularly on one cybercrime actor, KillNet. Segment Resources: Understanding DDoS Attacks: What is a DDoS Attack and How Does it Work? - I know the title makes this blog post sound rather basic, but it will get you up to speed on all the latest DDoS types, actors, and terminology pretty quickly! What is An Application-Layer DDoS Attack, and How Do I Defend Against Them? 2023 DDoS Statistics and Trends https://en.wikipedia.org/wiki/Killnet This week, Tyler and Adrian discuss Cyera's $300M Series C, which lands them a $1.4B valuation! But is that still a unicorn? Aileen Lee of Cowboy Ventures, who coined the term back in 2013, recently wrote a piece celebrating the 10th anniversary of the term, and revisiting what it means. We HIGHLY recommend checking it out: https://www.cowboy.vc/news/welcome-back-to-the-unicorn-club-10-years-later They discuss a few other companies that have raised funding or just come out of stealth, including Scrut Automation, Allure Security, TrojAI, Knostic, Prompt Armor. They discuss Eclipsium's binary analysis tooling, and what the future of fully automated security analysis could look like. Wiz acquired Gem, and Veracode acquired Longbow. Adrian LOVES Longbow's website, BTW. They discuss a number of essays, some of which are a must read: Daniel Miessler's Efficient Security Principle Subsalt's series on data privacy challenges Lucky vs Repeatable, a must-read from Morgan Housel AI has Flown the Coop, the latest from our absent co-host, Katie Teitler-Santullo Customer love by Ross Haleliuk and Rami McCarthy We briefly cover some other fun - reverse typosquatting, AI models with built-in RCE, and Microsoft having YET ANOTHER breach.

Jim joins the Security Weekly crew to discuss all things supply chain! Given the recent events with XZ we still have many topics to explore, especially when it comes to practical advice surrounding supply chain threats. Ahoi new VM attacks ahead! HTTP/2 floods, USB Hid and run, forwarded email tricks, attackers be scanning, a bunch of nerds write software and give it away for free, your TV is on the Internet, Rust library issue, D-Link strikes again, EV charging station vulnerabilities, and rendering all cybersecurity useless.

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 this 2-part episode, we'll discuss: - The current state of vendor offerings in cybersecurity - The difficulties of measuring value and efficacy in a product - How to avoid building a security program that centers around managing products - Shelfware - Minimizing product overhead - 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 Visit https://www.securityweekly.com/bsw for all the latest episodes!

As most of you have probably heard there was a scary supply chain attack against the open source compression software called "xz".

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. Segment Resources: Exploitation TImelines NVD Sources for known exploitation Exploitation in the Wild - Rockstar 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!
