Talos Takes

In this episode of Talos Takes, Amy Ciminnisi sits down with researcher Diana Brown to discuss the rise of "platform-as-a-proxy" (PAP) attacks. We explore how threat actors are weaponizing legitimate SaaS platforms like GitHub and Jira to deliver phishing campaigns that bypass traditional security filters. By leveraging the platforms' own infrastructure to send authenticated emails, attackers are exploiting the inherent trust employees place in these essential business tools. We break down the mechanics of these campaigns and provide actionable strategies for security teams to move beyond binary trust and implement contextual awareness to better protect their organizations.

In this episode, we unpack state-sponsored and phishing trends from the 2025 Talos Year in Review. Amy and Martin Lee explore the alarming rise of internal phishing campaigns that bypass traditional perimeter defenses, including the widespread weaponization of Microsoft 365's Direct Send feature. Beyond simple phishing, we analyze the aggressive, blended operations of state-sponsored actors from China and North Korea who are combining high-level zero-day exploits with sophisticated social engineering. From the "Dear Leader" interview test to the reality of fake developer personas, we break down exactly how these adversaries are infiltrating modern organizations.
