AFL-ICP: Enhancing Industrial Control Protocol Reliability via Specification-Guided Fuzzing
Jiaying Meng, Xuewei Feng, Qi Li +2
Industrial Control Protocols (ICPs) are critical to the reliability and stability of industrial infrastructure, yet their security is fundamentally compromised by a specification-b…
Invisible Adversaries: A Systematic Study of Session Manipulation Attacks on VPNs
Yuxiang Yang, Ao Wang, Xuewei Feng +2
Virtual Private Networks (VPNs) are widely used for censorship evasion and traffic protection. VPN users expect to be provided with adequate security protection, and at the same ti…
Off-Path TCP Exploits: PMTUD Breaks TCP Connection Isolation in IP Address Sharing Scenarios
Xuewei Feng, Zhaoxi Li, Qi Li +3
Path MTU Discovery (PMTUD) and IP address sharing are integral aspects of modern Internet infrastructure. In this paper, we investigate the security vulnerabilities associated with…
ReDAN: An Empirical Study on Remote DoS Attacks against NAT Networks
Xuewei Feng, Yuxiang Yang, Qi Li +6
In this paper, we conduct an empirical study on remote DoS attacks targeting NAT networks. We show that Internet attackers operating outside local NAT networks can remotely identif…
Exploiting Cross-Layer Vulnerabilities: Off-Path Attacks on the TCP/IP Protocol Suite
Xuewei Feng, Qi Li, Kun Sun +2
After more than 40 years of development, the fundamental TCP/IP protocol suite, serving as the backbone of the Internet, is widely recognized for having achieved an elevated level…
BlueSWAT: A Lightweight State-Aware Security Framework for Bluetooth Low Energy
Xijia Che, Yi He, Xuewei Feng +3
Bluetooth Low Energy (BLE) is a short-range wireless communication technology for resource-constrained IoT devices. Unfortunately, BLE is vulnerable to session-based attacks, where…
Exploiting Sequence Number Leakage: TCP Hijacking in NAT-Enabled Wi-Fi Networks
Yuxiang Yang, Xuewei Feng, Qi Li +3
In this paper, we uncover a new side-channel vulnerability in the widely used NAT port preservation strategy and an insufficient reverse path validation strategy of Wi-Fi routers,…
From Hardware Fingerprint to Access Token: Enhancing the Authentication on IoT Devices
Yue Xiao, Yi He, Xiaoli Zhang +5
The proliferation of consumer IoT products in our daily lives has raised the need for secure device authentication and access control. Unfortunately, these resource-constrained dev…
Pencil: Private and Extensible Collaborative Learning without the Non-Colluding Assumption
Xuanqi Liu, Zhuotao Liu, Qi Li +2
The escalating focus on data privacy poses significant challenges for collaborative neural network training, where data ownership and model training/deployment responsibilities res…
