In this episode of Exploited: The Cyber Truth, host Paul Ducklin is joined by RunSafe Security Founder and CEO Joseph M. Saunders and Salim Blume, Director of Security Applications, for a look at how copyleft risk emerges and why compliance in embedded products is more challenging than many teams expect. Salim breaks down how restrictive licenses, such as GPL and AGPL, can force the disclosure of proprietary code, interrupt product shipments, or create exposure long after devices are deployed in the field. Joe shares why accurate SBOMs, automated license checks, and enforcing policy at build time are critical to preventing surprises in downstream products. The discussion also touches on the ongoing Vizio case, where the TV manufacturer faces litigation that could compel public release of source code under the GPL, highlighting how open source obligations can surface years after products hit the market. Together, Paul, Joe, and Salim explore: How copyleft obligations can require source-code disclosureWhy embedded environments complicate license complianceReal-world cases where unnoticed GPL dependencies caused major issues, such as Vizio’s GPL lawsuit and Cisco’s WRT54G router familyThe growing implications of AGPL for SaaS and connected servicesHow build-time SBOMs and automated controls reduce long-term risk Whether you're building connected devices, managing software supply chain compliance, or protecting proprietary IP, this episode offers practical guidance to reduce copyleft risk before it becomes a costly problem.The podcast and artwork embedded on this page are from RunSafe Security, which is the property of its owner and not affiliated with or endorsed by Listen Notes, Inc.
