Jamming-Resistant AAV Communications: a Multichannel-Aided Approach
Jamming cancellation is essential to reliable unmanned autonomous vehicle AAV communications in the presence of malicious jammers. In this paper, we develop a practical multichannel-aided jamming cancellation method to realize secure AAV communications. The proposed method is capable of...
Enhancing Resilience against Jamming Attacks: a Cooperative Anti-Jamming Method Using Direction Estimation
The inherent vulnerability of wireless communication necessitates strategies to enhance its security, particularly in the face of jamming attacks. This paper uses the collaborations of multiple sensing nodes SNs in the wireless network to present a cooperative anti-jamming approach CAJ designed t...
CWGAN-GP Augmented CAE for Jamming Detection in 5G-NR in Non-IID Datasets
In the ever-expanding domain of 5G-NR wireless cellular networks, over-the-air jamming attacks are prevalent as security attacks, compromising the quality of the received signal. We simulate a jamming environment by incorporating additive white Gaussian noise AWGN into the real-world In-phase and...
Graph Neural Networks for Jamming Source Localization
Graph-based learning provides a powerful framework for modeling complex relational structures; however, its application within the domain of wireless security remains significantly underexplored. In this work, we introduce the first application of graph-based learning for jamming source...
SATversary: Adversarial Attacks on Satellite Fingerprinting
As satellite systems become increasingly vulnerable to physical layer attacks via SDRs, novel countermeasures are being developed to protect critical systems, particularly those lacking cryptographic protection, or those which cannot be upgraded to support modern cryptography. Among these is...
A GPS Blackout Would Shut Down the World
GPS jamming and spoofing attacks are on the rise. If the global navigation system the US relies on were to go down entirely, it would send the world into unprecedented chaos...
Weak-Jamming Detection in IEEE 802.11 Networks: Techniques, Scenarios and Mobility
State-of-the-art solutions detect jamming attacks ex-post, i.e., only when jamming has already disrupted the wireless communication link. In many scenarios, e.g., mobile networks or static deployments distributed over a large geographical area, it is often desired to detect jamming at the early...
CVE-2024-55563
Bitcoin Core through 27.2 allows transaction-relay jamming via an off-chain protocol attack, a related issue to CVE-2024-52913. For example, the outcome of an HTLC Hashed Timelock Contract can be changed because a flood of transaction traffic prevents propagation of certain Lightning channel...
CVE-2021-40171
The absence of notifications regarding an ongoing RF jamming attack in the SecuritasHome home alarm system, version HPGW-G 0.0.2.23F BGU-ITR-F1-BDBL.A30.20181117, allows an attacker to block legitimate traffic while not alerting the owner of the system...
CVE-2019-14261
An issue was discovered on ABUS Secvest FUAA50000 3.01.01 devices. Due to an insufficient implementation of jamming detection, an attacker is able to suppress correctly received RF messages sent between wireless peripheral components, e.g., wireless detectors or remote controls, and the ABUS...
Simultaneously Exposing and Jamming Covert Communications Via Disco Reconfigurable Intelligent Surfaces
Covert communications provide a stronger privacy protection than cryptography and physical-layer security PLS. However, previous works on covert communications have implicitly assumed the validity of channel reciprocity, i.e., wireless channels remain constant or approximately constant during the...
Antifragility of RIS-Assisted Communication Systems under Jamming Attacks
Antifragility of communication systems is defined as measure of benefits gained from the adverse events and variability of its environment. In this paper, we introduce the notion of antifragility in Reconfigurable Intelligent Surface RIS assisted communication systems affected by a jamming attack...
Satellite Navigation Systems Facing Rising Jamming and Spoofing Attacks
Satellite navigation systems are under rising threat from jamming and spoofing attacks, risking aviation, maritime, and telecom safety worldwide, warn global agencies...
The unexpected effects of GPS spoofing on aviation safety
GPS is one service in the Global Navigation Satellite System GNSS. Others include Russia’s GLONASS and the EU’s Galileo constellations. These are all used to provide Position, Navigation, and Timing PNT to civilian users including commercial aircraft. GPS was actually designed to have military...
The Invisible Russia-Ukraine Battlefield
In Russia’s war against Ukraine, electronic warfare, including signal-jamming, anti-drone weapons, and innovative protections for critical military systems, has become a key piece of the conflict...
CVE-2024-55563: Allocation of Resources Without Limits or Throttling
Bitcoin Core through 27.2 allows transaction-relay jamming via an off-chain protocol attack, a related issue to CVE-2024-52913. For example, the outcome of an HTLC Hashed Timelock Contract can be changed because a flood of transaction traffic prevents propagation of certain Lightning channel...

CVE-2024-55563
Bitcoin Core versions prior to 27.3 (through 27.2) are vulnerable to transaction-relay jamming via an off-chain protocol attack. This issue allows an attacker to flood transaction traffic, preventing the propagation of specific Lightning channel transactions and potentially altering the outcome o...
