FlyBlind: Cross-Slice Timeliness Attacks on UAV Situational Awareness over 5G
Wagner Comin Sonaglio, Ágney Lopes Roth Ferraz, Sidnei Barbieri +3
Beyond Visual Line of Sight (BVLOS) Uncrewed Aerial Systems (UAS) operating over 5G Standalone (SA) networks use a shared User Plane for both command-and-control (C2) data and vide…
When Connectivity Is Not Enough: Cross-Layer Attacks on UAV C2 over 5G
Wagner Comin Sonaglio, Ágney Lopes Roth Ferraz, André Elias Melo +3
Beyond Visual Line of Sight (BVLOS) unmanned aerial vehicle (UAV) operations increasingly use 5G standalone (SA) networks for command and control (C2) between the UAV and the groun…
AirCatch: Effectively tracing advanced tag-based trackers
Abhishek Kumar Mishra, Swadeep, Guevara Noubir +1
Tag-based tracking ecosystems help users locate lost items, but can be leveraged for unwanted tracking and stalking. Existing protocol-driven defenses and prior academic solutions…
Establishing Trust in the Beyond-5G Core Network using Trusted Execution Environments
Marinos Vomvas, Norbert Ludant, Guevara Noubir
The fifth generation (5G) of cellular networks starts a paradigm shift from the traditional monolithic system design to a Service Based Architecture, that fits modern performance r…
Unprotected 4G/5G Control Procedures at Low Layers Considered Dangerous
Norbert Ludant, Marinos Vomvas, Guevara Noubir
Over the years, several security vulnerabilities in the 3GPP cellular systems have been demonstrated in the literature. Most studies focus on higher layers of the cellular radio st…
Spectrum-Flexible Secure Broadcast Ranging
Tien D. Vo-Huu, Triet D. Vo-Huu, Guevara Noubir
Secure ranging is poised to play a critical role in several emerging applications such as self-driving cars, unmanned aerial systems, wireless IoT devices, and augmented reality. I…
A Privacy-Preserving Longevity Study of Tor's Hidden Services
Amirali Sanatinia, Jeman Park, Erik-Oliver Blass +2
Tor and hidden services have emerged as a practical solution to protect user privacy against tracking and censorship. At the same time, little is known about the lifetime and natur…
Mitigating Location Privacy Attacks on Mobile Devices using Dynamic App Sandboxing
Sashank Narain, Guevara Noubir
We present the design, implementation and evaluation of a system, called MATRIX, developed to protect the privacy of mobile device users from location inference and sensor side-cha…
Security of GPS/INS based On-road Location Tracking Systems
Sashank Narain, Aanjhan Ranganathan, Guevara Noubir
Location information is critical to a wide-variety of navigation and tracking applications. Today, GPS is the de-facto outdoor localization system but has been shown to be vulnerab…
Honey Onions: a Framework for Characterizing and Identifying Misbehaving Tor HSDirs
Amirali Sanatinia, Guevara Noubir
In the last decade, Tor proved to be a very successful and widely popular system to protect users' anonymity. However, Tor remains a practical system with a variety of limitations,…
OnionBots: Subverting Privacy Infrastructure for Cyber Attacks
Amirali Sanatinia, Guevara Noubir
Over the last decade botnets survived by adopting a sequence of increasingly sophisticated strategies to evade detection and take overs, and to monetize their infrastructure. At th…
CBM: A Crypto-Coded Modulation Scheme for Rate Information Concealing and Robustness Boosting
Triet D. Vo-Huu, Guevara Noubir
Exposing the rate information of wireless transmission enables highly efficient attacks that can severely degrade the performance of a network at very low cost. In this paper, we i…
