Summary
This episode of IBM’s “Security Intelligence” podcast delves into three pressing topics at the intersection of artificial intelligence and cybersecurity. Host Matt Kosinski, joined by panelists Claire Nunez, Dustin “EvilMog” Heywood, and Ian Molloy, first discusses the implications of open-weight AI models like GLM-5.2, which are reportedly achieving “Mythos-level capabilities.” The core concern is that while large, proprietary “frontier models” are being safeguarded with guardrails, open-source equivalents are readily available to malicious actors who can modify or “obliterate” safety features. The panelists agree that attempting to “put the AI genie back in the bottle” is futile; instead, the focus should be on empowering defenders with AI tools to harden networks, acknowledging that bad actors will always find ways to exploit powerful, unrestricted models, especially as they become more efficient and run on less powerful hardware.
Next, the discussion shifts to CISA’s new 4-variable model for prioritizing vulnerabilities, replacing the long-standing CVSS scores. This new directive, primarily for federal agencies but with potential for broader adoption, evaluates vulnerabilities based on public exposure, real-world exploitation, automatable exploitation, and potential for total system control, assigning rapid remediation timelines (e.g., three days for critical issues). While Claire Nunez sees potential for clearer communication and faster patching, especially for executive decision-makers, EvilMog and Ian Molloy express skepticism. They point out that previous scoring systems were often neglected, and the new model might still struggle with the practical realities of resource allocation and addressing complex chains of lower-severity vulnerabilities. A significant underlying question is whether organizations can realistically meet these accelerated patching demands, a task many are not currently equipped for.
Finally, the podcast explores “vibe hunting,” an emerging concept akin to “vibe coding” that involves using AI to automate threat hunting. Ian Molloy and EvilMog acknowledge its potential to accelerate and enhance human-constrained threat hunting processes, especially for repetitive tasks like triage and data enrichment. However, concerns are raised about the cost of such advanced AI systems and the potential for human defenders to lose critical “muscle memory” or fundamental skills if they become overly reliant on automation. Claire Nunez emphasizes that robust human expertise remains essential to effectively guide AI, craft nuanced queries, and interpret results, preventing a false sense of security or the oversight of subtle threats.
The overarching takeaway from the episode is that the rapid advancement of AI presents both immense opportunities and significant challenges in cybersecurity. Whether it’s the proliferation of powerful open-source models, the adoption of new vulnerability prioritization frameworks, or AI-driven threat hunting, the success of these innovations hinges on strategic implementation, continuous human skill development, and a realistic assessment of AI’s capabilities and limitations. Rather than viewing AI as a replacement, the consensus suggests it must be integrated as a sophisticated assistant that augments human intelligence and efficiency, enabling defenders to keep pace in an increasingly complex and automated threat landscape.

Z.ai’s GLM-5.2 is, according to some, as good at finding vulnerabilities as Mythos. Or at least, close to it. And it’s open weight.
On this episode of Security Intelligence, we dig into how powerful, open AI models are bringing frontier-style capabilities to more people, all while the proprietary models are emphasizing safeguards. What does it mean for cybersecurity pros? Security emergency, or a whole lot of hype?
Then, we explore how CISA’s new BOD 26-04 ditches the old CVSS scoring system for a four-variable model that could reshape how every security team prioritizes vulnerabilities. We also unpack “vibe hunting,” the AI-assisted evolution of threat hunting, and break down the commercial launch of Red Hat and IBM’s Lightwell. Securing open-source software in the AI era requires new approaches. Learn how Lightwell does it: https://ibm.biz/~fJaPqPXz3
