DoSQ: A Cross-Layer Denial of Service Quality Attack by Exploiting Side Channels in 5G NR

A cross-layer denial-of-service attack exploits 5G NR side channels to degrade mission-critical service quality — a concern for European operators relying on 5G for critical infrastructure and Industry 4.0.

arXiv:2607.16102v1 Announce Type: new Abstract: The 3rd Generation Partnership Project (3GPP)'s Fifth Generation New Radio (5G NR) is critical to supporting mission-critical services. However, 5G systems are vulnerable to smart jamming attacks that can propagate to applications running on top of these networks (i.e., cross-layer). The 5G gNB broadcasts resource scheduling information for the legitimate UEs over the air interface, with a prevailing assumption that this surface alone reveals noth

Editorial Analysis

Why it matters

As European critical-infrastructure operators migrate to 5G-based connectivity, smart jamming attacks that evade conventional defences pose a tangible availability risk.

What to do

If deploying private 5G for OT environments, request your network vendor's assessment of resilience against cross-layer side-channel jamming.

Board brief

A newly demonstrated 5G attack can silently degrade mission-critical service quality, potentially affecting industrial 5G rollouts.
