A Queryable Graph-Based Security Analysis Framework for O-RAN
Corban Villa, Michele Guerra, Syed Khandker +3
The Open Radio Access Network (O-RAN) replaces vendor-locked RANs with a modular and interoperable architecture that fosters competition and accelerates innovation. With this openn…
TBRD: TESLA Authenticated UAS Broadcast Remote ID
Jason Veara, Manav Jain, Kyle Moy +1
Mysterious sightings of Unmanned Aircraft Systems (UAS) over U.S. military facilities, suburban neighborhoods, and commercial airports have intensified scrutiny of drone activity.…
Security Analysis of LTE Connectivity in Connected Cars: A Case Study of Tesla
Evangelos Bitsikas, Jason Veara, Aanjhan Ranganathan
Modern connected vehicles rely on persistent LTE connectivity to enable remote diagnostics, over-the-air (OTA) updates, and safety-relevant services. While mobile network vulnerabi…
Security Analysis of 5G NR Device-to-Device Sidelink Communications
Evangelos Bitsikas, Aanjhan Ranganathan
5G NR sidelink communication enables new possibilities for direct device-to-device interactions, supporting applications from vehicle-to-everything (V2X) systems to public safety,…
Freaky Leaky SMS: Extracting User Locations by Analyzing SMS Timings
Evangelos Bitsikas, Theodor Schnitzler, Christina Pöpper +1
Short Message Service (SMS) remains one of the most popular communication channels since its introduction in 2G cellular networks. In this paper, we demonstrate that merely receivi…
Experience Report on the Challenges and Opportunities in Securing Smartphones Against Zero-Click Attacks
Narmeen Shafqat, Cem Topcuoglu, Engin Kirda +1
Zero-click attacks require no user interaction and typically exploit zero-day (i.e., unpatched) vulnerabilities in instant chat applications (such as WhatsApp and iMessage) to gain…
Cryptography Is Not Enough: Relay Attacks on Authenticated GNSS Signals
Maryam Motallebighomi, Harshad Sathaye, Mridula Singh +1
Civilian-GNSS is vulnerable to signal spoofing attacks, and countermeasures based on cryptographic authentication are being proposed to protect against these attacks. Both Galileo…
ZLeaks: Passive Inference Attacks on Zigbee based Smart Homes
Narmeen Shafqat, Daniel J. Dubois, David Choffnes +3
Zigbee is an energy-efficient wireless IoT protocol that is increasingly being deployed in smart home settings. In this work, we analyze the privacy guarantees of Zigbee protocol.…
SemperFi: A Spoofer Eliminating GPS Receiver for UAVs
Harshad Sathaye, Gerald LaMountain, Pau Closas +1
It is well-known that GPS is vulnerable to signal spoofing attacks. Although several spoofing detection techniques exist, they are incapable of mitigation and recovery from stealth…
I Send, Therefore I Leak: Information Leakage in Low-Power Wide Area Networks
Patrick Leu, Ivan Puddu, Aanjhan Ranganathan +1
Low-power wide area networks (LPWANs), such as LoRa, are fast emerging as the preferred networking technology for large-scale Internet of Things deployments (e.g., smart cities). D…
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…
On the Security of Carrier Phase-based Ranging
Hildur Ólafsdóttir, Aanjhan Ranganathan, Srdjan Capkun
Multicarrier phase-based ranging is fast emerging as a cost-optimized solution for a wide variety of proximity-based applications due to its low power requirement, low hardware com…
