On this week's episode of The Microsoft Threat Intelligence Podcast, Sherrod DeGrippo is joined by Thomas Roccia and Andres Freund. Andres stumbled upon a security issue within SSH while investigating performance discrepancies. He discovered a sophisticated backdoor, skillfully concealed within the LZMA library, part of the XZ package. Sherrod, Thomas, and Andres discuss the importance of proactive security measures and code review in the open-source community. They emphasize the critical role of community collaboration in identifying and mitigating security threats effectively and signal the need for heightened vigilance.  

In this episode you’ll learn:      

• The importance of proactive security and code review in the open-source community 
• Why anomalies in software behavior should prompt curiosity and investigation 
• Open-source community cooperation is vital for spotting and addressing security risks 

Some questions we ask:
