Si Hui Ong from National University of Singapoore delves into the advanced security challenges faced by centralized cryptocurrency exchanges, focusing on the February 2025 Bybit breach, where hackers exploited multi-signature vulnerabilities through UI deception and social engineering. We introduce a Hybrid Security Architecture that leverages AI-driven smart contract analysis, Graph Neural Networks (GNNs) for anomaly detection, and federated learning for global threat intelligence.
The talk will cover practical implementations using CodeBERT and GraphCodeBERT for code auditing, as well as decentralized verification mechanisms using on-chain AI nodes. Attendees will gain actionable insights into securing centralized exchanges against sophisticated attacks while maintaining regulatory compliance.
