Three Buddy Problem
The Three Buddy Problem is a popular Security Conversations podcast that goes beyond industry talking points to discuss what others won’t -- nation-state malware, attribution, cyberwar, ethics, privacy, and the messy realities of securing computers and corporate networks.
Hosted by three veteran security pros -- journalist Ryan Naraine and malware paleontologists Costin Raiu and Juan Andres Guerrero-Saade -- the weekly show attracts a highly engaged audience of security researchers, corporate defenders, CISOs, and policymakers.
