In this episode of the Microsoft Threat Intelligence Podcast, host⁠ ⁠⁠Sherrod DeGrippo is joined by Tori Murphy, Anna Seitz, and Chuong Dong to break down two threats: the modular backdoor PipeMagic and Medusa ransomware. They discuss how PipeMagic disguises itself as a ChatGPT desktop app to deliver malware, its sophisticated modular design, and what defenders can do to detect it.  
The team also explores Medusa’s evolution into a ransomware-as-a-service model, its use of double extortion tactics, and the broader threat landscape shaped by ransomware groups, social engineering, and the abuse of legitimate tools.  
In this episode you’ll learn:      
Why modular malware is harder to detect and defend against 
How attackers abuse vulnerable drivers to disable security tools 
Why leak sites play a central role in ransomware operations 
Some questions we ask:     
How did Microsoft researchers uncover PipeMagic in the wild? 
Why do ransomware groups often borrow names and themes from mythology? 
What initial access techniques are commonly associated with Medusa attacks?
