A report from Nozomi Networks reveals that 94% of analyzed Wi-Fi networks lack defenses against deauthentication attacks, a common form of denial-of-service (DoS) attack. These attacks can disrupt operations by disconnecting devices from the network and pave the way for more significant cyber threats. The study emphasized the absence of management frame protection (MFP) in most networks, leaving them, including critical national infrastructure, highly susceptible to exploitation. This vulnerability poses risks in various sectors, from healthcare to industrial environments, potentially leading to unauthorized access and severe system interference.
"They leverage a built-in feature in the Wi-Fi protocol, specifically in the management frames used for communication between devices and access points."
"The vast majority of wireless networks, including those in mission-critical environments, remain highly exposed to these kinds of attacks."
