Wi-Fi is a family of wireless network protocols, based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks in the world, used globally in home and small office networks to link desktop and laptop, computers, smartphones, smart TVs, printers, and smart speakers together to a wireless router to connect them to the Internet, and in wireless access points in public places like coffee shops, hotels, libraries and airports to provide the public Internet access for mobile devices.



The term FragAttack (a mashup of ‘fragmentation’ and ‘aggregation’) is all about WiFi’s handling of data. FragAttacks could allow hackers within a device’s WiFi radio range to gather information about its owner and introduce malware to compromise intelligent devices such as computers or smartphones—even those protected by standard WiFi security protocol such as WEP WPA2 or WPA3. These vulnerabilities have to do with design flaws in the WiFi standard itself, while others have to do with how manufacturers of devices implement WiFi. With this vulnerability, adversaries might abuse the vulnerabilities to get the victim’s login details and hackers can exploit exposed Internet-of-Things (IoT) devices by activating and deactivating a smart power socket. A report says, many vendors have already released patches for some of their products.
