About me

Welcom to my homepage!

My name is Ming Xu. I am a research fellow in NUS (National University of Singapore), working with Jiaheng Zhang and Jin Song Dong. I received my Ph.D. Degree from Fudan University under the supervision of Prof. Weili Han.

I am working to protect the digital safety of everyone online in the usable security and privacy aspects. My interests span security, privacy, fraud, misinformation, and practical applications of agentic AIs. Several works are listed below.

• Digital Forensics: Agentic SOC represents a paradigm shift in security operations, integrating autonomous agents to streamline the threat detection and response. Key components include Agentic SIEM-rule creation ICSE’26, SIEM-rule conversion, and LLM-based Web Anomaly Detectors ASE’24, which together enable adaptive, intelligent, and scalable threat discovery.
• Robust Authentications: Designing the next-generation robust authentication mechanisms by uncovering the behavioral and structural foundations of human-chosen passwords. Our work reveals the inherent patterns of textual passwords such as “p@ssw0rd4ever” CCS’21, exposes real-world password guessing behaviors and practical attack scenarios USENIX SEC’23, TDSC’25, and identifies emerging privacy risks within probabilistic strength meters (PSMs) AsiaCCS’25.
