| 6/21/26 |  Navigating the GPS threat landscape, with Brandon Karpf. | Traditionally, GPS jamming attacks have been confined to the ground; however, new data shows that these attacks could be moving to target signals before they even reach the ground. In this week’s episode, host Maria Varmazis sits down with Dave Bittner and Brandon Karpf to discuss recent research that suggests the attack landscape for GPS attacks is expanding. If this research is accurate, these attacks represent a significant evolution for how defenders think about this critical technology. Key sources: Something is jamming GPS over Europe.

| 6/14/26 |  Securing satellites already in space, with journalist Shaun Waterman. | For years, space cybersecurity has been a long sought after goal, but due to operational constraints, it was largely unfeasible. In this week’s episode, host Maria Varmazis sits down with journalist Shaun Waterman to discuss his recent article “The Newest Space Race is Cyber.” As space has increasingly become a critical infrastructure component, industry leaders and security agencies alike have begun to launch new initiatives to improve capabilities both on the ground and in orbit. Key sources: The Newest Space Race is Cyber. DHS Wants Satellite Volunteers to Test New Cyber Tools. Five Teams of Hackers will Compete to Breach US Satellite in Space. Like what you heard?

Hosted by the NATO Cooperative Cyber Defence Centre of Excellence and led by NATO Allied Command Transformation, Cyber Coalition is a defensive-only exercise built around collaboration, coordination, and information sharing across allied nations. This episode highlights how that plays out in practice, from legal teams working through cross-border policy questions to military defenders coordinating with civilian infrastructure partners inside NATO’s secure cyber range.
