Season 1 - Episode 20 (Pedro Kertzman & Sarah Freeman)

Remember when critical infrastructure defenders had to convince people that cyber attacks were even possible? Those days are gone. Today's challenge is prioritizing defenses in a landscape where threats are multiplying faster than resources.Sarah Freeman, Chief Engineer for Intelligence Modeling and Simulation at MITRE's Cyber Infrastructure Protection Innovation Center, takes us on a journey through the evolution of industrial security. With over a decade of experience protecting the systems that power our world, she offers a refreshing perspective that cuts through both complacency and fear.The conversation explores how industrial security has matured from basic awareness to strategic defense. Sarah reveals how threat actors have shifted tactics, increasingly targeting third-party providers as a way to compromise multiple critical infrastructure customers simultaneously. "More and more of the actors target those companies deliberately," she explains. "By compromising this one entity, they have theoretical access to all of these customers."We dive into the practical challenges of security in operational technology environments, where the sheer volume of vulnerabilities has become overwhelming. Rather than attempting to patch everything, Sarah advocates for a more targeted approach based on anticipating adversary capabilities—a "cyber forecast" that helps organizations focus limited resources where they matter most.The discussion also tackles the integration of artificial intelligence into traditionally isolated control systems, offering insights on balancing innovation with security. For threat intelligence professionals looking to specialize in industrial security, Sarah provides guidance on essential resources and community connections.Whether you're responsible for critical infrastructure protection or simply interested in understanding the unique challenges of securing systems where digital meets physical, this episode offers valuable perspective from someone who's been on the front lines since before most people recognized the threat existed.Listen now to gain insights that will help you think more strategically about protecting the systems that power our modern world.

Season 1 - Episode 19 (Pedro Kertzman & Tammy Harper)

Imagine a criminal enterprise so sophisticated it employs lawyers, creates flashy recruitment videos, and operates its own university. Welcome to the modern ransomware ecosystem, expertly decoded by threat intelligence researcher Tammy Harper in this eye-opening episode.Harper pulls back the curtain on the surprisingly corporate structure of ransomware operations, revealing a three-tiered hierarchy ranging from invite-only "syndicates" managing millions in cryptocurrency to small "operators" struggling to recruit talent, down to inexperienced "script kiddies" with minimal operational security. The business models are equally fascinating – Ransomware-as-a-Service providers take a 20% cut while offering everything from malware payloads to secure communication channels and victim-shaming blogs.What's truly alarming is how these criminal groups continue to innovate their extortion techniques. As fewer victims pay ransoms (just one in twenty pay significant amounts), gangs are escalating pressure tactics. Some offer affiliates legal counsel to identify regulatory pressure points, others implement AI-assisted negotiations to counter traditional stalling tactics, and some are even calling victims' clients directly to orchestrate supply chain attacks.Harper dispels common misconceptions about attack vectors too. Modern ransomware rarely arrives as an email attachment – instead, attacks begin with phishing emails containing Trojans, followed by extensive reconnaissance lasting weeks or even months. "When you see your systems encrypted," she warns, "it's too late." The longest compromise she witnessed lasted a full year from initial infection to ransomware deployment, despite law enforcement warnings to the victim.Whether you're a cybersecurity professional or simply curious about digital threats, this episode provides rare insights into a criminal ecosystem that continues to evolve despite increasing law enforcement pressure. Listen now to understand the tactics that make modern ransomware so persistent and how organizations can better protect themselves.Send us a textSupport the showThanks for tuning in!

Season 1 - Episode 18 (Pedro Kertzman & Freddy Murre)

"Basically, everyone just do  whatever they feel like and then call it intelligence." With these provocative words, Freddy Murre cuts straight to the heart of what's wrong with most cyber threat intelligence practices today.Drawing from 13 years of intelligence experience spanning military operations and private sector work, Freddy exposes the critical disconnect between intelligence methodology and what many CTI teams actually deliver. Most security teams, he argues, are producing cyber threat information, not intelligence—pushing technical indicators without context, relevance, or the crucial "so what" that decision-makers need.The conversation explores how CTI professionals often fall back on their technical comfort zones rather than embracing true intelligence tradecraft. Freddy walks us through the intelligence cycle, explaining how requirements drive collection and analysis to produce actionable insights. He challenges the industry norm of one-directional "data dumps" from vendors to customers, advocating instead for a more tailored approach that considers each organization's specific technologies, vulnerabilities, and business needs.Perhaps most valuable is Freddy's practical guidance on stakeholder engagement—identifying who your intelligence serves, understanding their decision-making needs, and continually validating that your work delivers measurable value. "If they can't articulate the decisions they made based on your intelligence," he warns, "you're in a dark space." His Ferrari analogy brilliantly illustrates how CTI teams must find the right fit between capabilities and stakeholder requirements.The episode also tackles AI's impact on intelligence work, with Freddy offering a sobering assessment of large language models' limitations while acknowledging their potential benefits when properly understood as tools rather than solutions. Whether you're a seasoned CTI professional or just building your program, this conversation provides an essential framework for elevating your practice from information sharing to true intelligence production.Send us a textSupport the showThanks for tuning in!

Season 1 - Episode 16 (Pedro Kertzman & Gert-Jan Bruggink)

The cybersecurity industry has a people problem. While we chase after the latest tools and technologies, we're overlooking what Gert-Jan Bruggink calls "the human element" – the critical factor that connects technical solutions with actual security outcomes. In this thought-provoking conversation, Gert-Jan shares his journey from security engineering to pioneering scenario-based threat intelligence, revealing how his curiosity drove him to understand the "why" behind security implementations.Gert-Jan pulls no punches in addressing what he sees as an existential threat to the Cyber Threat Intelligence field. "If the CTI industry does not resolve this situation before 2030, the current commoditized form will become obsolete," he warns, highlighting the dangerous disconnect between technical intelligence and strategic applications. His work developing the CTI Capability Maturity Model (CTI-CMM) represents a community-driven effort to bridge these gaps through continuous improvement and practitioner leadership.The discussion takes a fascinating turn when Gert-Jan introduces systems thinking as the missing piece in modern cybersecurity approaches. Rather than viewing security in silos, he advocates for understanding the entire organizational ecosystem and the narratives that connect problems across different departments. This holistic perspective helps explain why even sophisticated security tools often fail to deliver their promised value – they're implemented without consideration for the broader context.What sets this conversation apart is Gert-Jan's balanced view of technology and humanity. He doesn't reject technological solutions but argues for a hybrid approach that leverages both human intelligence and technological advancements. His insights on tracking subtle adversary trends over time demonstrate the irreplaceable value of human analysis and pattern recognition in threat intelligence.Ready to transform how you think about cybersecurity?

Season 1 - Episode 11 (Pedro Kertzman & Ondra Rojčík)

From nuclear weapons research to reshaping Europe's stance on Chinese technology in critical infrastructure, Andra Rojčík's journey into cyber threat intelligence defies conventional career paths. As a principal CTI analyst who teaches intelligence analysis tradecraft, Andra brings unique perspectives from his experience at NATO, the Czech Intelligence Agency, and now Red Hat.During his time leading the Strategic Cyber Threat Intelligence function at the Czech National Cybersecurity Agency, Andra's team produced analysis on Huawei that transformed the European narrative around technology sovereignty. "Technology is actually a pretty political issue," Andra explains, challenging the previously accepted notion that technology remains neutral regardless of origin.The conversation explores fascinating contrasts between government and private sector intelligence work. While government analysts often face unpredictable demands from high-level officials who understand intelligence terminology, private sector CTI requires translating insights into actionable steps for stakeholders who may rarely encounter intelligence products. This demands CTI professionals go beyond assessments to help operationalize findings into concrete security controls.Andra breaks down the discipline into three essential components that every analyst must develop: Cyber (information security concepts), Threat (adversary operations), and Intelligence (analytical principles). Many technically-skilled professionals overlook the intelligence tradecraft element, which Andra addresses through workshops helping analysts avoid "admiring problems" and instead deliver actionable intelligence. For those looking to develop their skills, he recommends resources like "Thinking Fast and Slow" by Daniel Kahneman and "Critical Thinking for Strategic Intelligence" by Katherine Hibbs Pherson and Randolph H. Pherson.Whether you're contemplating a career pivot into cyber threat intelligence or seeking to strengthen your analytical capabilities, this episode offers valuable insights from someone who has successfully navigated both government and corporate intelligence landscapes.
