Unlocking Backdoor AI Poisoning with Dmitrijs Trizna

Dmitrijs Trizna, Security Researcher at Microsoft joins Nic Fillingham on this week's episode of The BlueHat Podcast. Dmitrijs explains his role at Microsoft, focusing on AI-based cyber threat detection for Kubernetes and Linux platforms. Dmitrijs explores the complex landscape of securing AI systems, focusing on the emerging challenges of Trustworthy AI. He delves into how threat actors exploit vulnerabilities through techniques like backdoor poisoning, using gradual benign inputs to deceive AI models. Dmitrijs highlights the multidisciplinary approach required for effective AI security, combining AI expertise with rigorous security practices. He also discusses the resilience of gradient-boosted decision trees against such attacks and shares insights from his recent presentation at Blue Hat India, where he noted a strong interest in AI security.  

In This Episode You Will Learn:
