CHAOS: Exploiting WiFi Time Synchronization for Covert Communication | NDSS 2025 Session 1A

Discover how researchers from the University of Utah are pushing the boundaries of WiFi security! This NDSS 2025 presentation by Sirus Shahini and Robert Ricci reveals CHAOS, a groundbreaking technique that leverages WiFi's Timing Synchronization Function (TSF) to create a covert communication channel. Learn how CHAOS hides data within the inherent noise of WiFi beacon frames, achieving a robust 520 bits/s data rate without modifying standard hardware. Explore the implications for network security and the potential for further TSF exploitation. Key Takeaways: Understanding WiFi's TSF and its vulnerabilities How CHAOS encodes data in beacon frame ordering and TSF timestamps The potential for covert communication in noisy WiFi environments Implications for network security and future research directions Presented at NDSS 2025 - Session 1A: WiFi and Bluetooth Security Speakers: Sirus Shahini (University of Utah), Robert Ricci (University of Utah)
