Summary

The webinar by Dr. Hamida İrfan, a postdoctoral fellow at the Canadian Institute for Cybersecurity, explores the evolution of Advanced Persistent Threat (APT) attribution from traditional indicator-based methods to AI-driven approaches. She begins by defining cyber attribution and its three levels: technical, behavioral, and strategic. She explains why APT attribution is challenging due to the sophisticated, evolving tactics of state-sponsored groups. The talk then focuses on Deep Reinforcement Learning (DRL) as a promising method for adaptive attribution, detailing its components (state, action, reward, policy) and mapping them to the attribution context. She presents a reference study that uses DRL to attribute malware samples to APT groups, achieving high accuracy. The presentation also addresses limitations of AI approaches, such as computational cost, lack of explainability, and privacy concerns. Solutions like model pruning, Explainable AI (XAI), and Federated Learning are discussed, with a specific framework called XFedHunter combining FL and XAI. The Q&A session covers how DRL outperforms traditional ML, balancing accuracy and privacy, benefits of XAI, challenges in FL, and future research directions.
