Deauthentication attacks exploit weaknesses in network protocols to force devices off a Wi-Fi network, causing disruptions that can pave the way for more severe cyber threats. Attackers manipulate a feature in the Wi-Fi protocol by sending fraudulent deauthentication frames, tricking devices into disconnecting. While the immediate impact may seem limited to temporary network interruptions, these attacks are often the first step in larger cyber operations, leading to data breaches and unauthorized access.
One of the key findings of the report is that only 6% of wireless networks analyzed had management frame protection (MFP), a critical security feature that prevents attackers from spoofing network management frames. Without MFP, networks—including those supporting critical national infrastructure (CNI)—are left exposed to malicious actors.
The consequences of such vulnerabilities are particularly concerning in high-stakes industries.
In healthcare, cybercriminals could exploit weak wireless security to access sensitive patient data or interfere with critical medical systems. Industrial environments are also at risk, where a network disruption could halt production lines, disrupt automated processes, or even create safety hazards for workers.
With increasing cyberattacks targeting essential sectors, wireless security has become a pressing issue. State-sponsored hacking groups, such as Volt Typhoon and Salt Typhoon, have been linked to breaches in U.S. telecom networks, compromising sensitive communications and establishing persistent access to critical infrastructure networks.
These incidents highlight how Wi-Fi vulnerabilities can have far-reaching consequences beyond just business operations.
The report also identified several other major threats to wireless networks. Rogue access points, for instance, allow attackers to impersonate legitimate networks, tricking devices into connecting and exposing sensitive data. Jamming attacks can overwhelm networks, causing disruptions, while eavesdropping attacks on unencrypted protocols enable cybercriminals to steal credentials and monitor activity.
To counter these risks, Nozomi Networks recommends a proactive approach to wireless security. Organizations should conduct regular security audits, prioritize anomaly detection, and strengthen endpoint security. Implementing network segmentation can also help limit the impact of potential breaches. By adopting dynamic security strategies rather than static defenses, businesses can reduce their risk exposure and enhance their overall cybersecurity posture.
