Abstract
Wi-Fi networks are often susceptible to signal interference that can disrupt services, intercept sensitive data, and allow unauthorized access. Exploiting this vulnerability, attackers can launch Intentional Electromagnetic Interference (IEMI) attacks or protocol-based attacks. IEMI attacks include, but are not limited to, jamming, which involves the introduction of interference signals in the frequency band used by a given Wi-Fi network, thus disrupting its proper operation. The article presents research on different types of IEMI attacks, aimed at illustrating this type of threat to video transmission from Wi-Fi cameras and discusses methods of protection against this type of attack. The paper examines the methods of jamming the wireless network band, which are used on the distribution methods and the Sweeping Jammer methods that cyclically disrupt all available devices. Based on experiments, it has been confirmed that SOHO devices are highly susceptible to this type of simple attacks and implementing a method to minimize the effects of jamming yields poor results. The simplicity of this type of attack and the high availability of software and hardware tools on the market make the threat highly popular and still dangerous.
