FragAttacks
FragAttacks, or fragmentation and aggregation attacks, are a group of Wi-Fi vulnerabilities discovered by security research Mathy Vanhoef. Since the vulnerabilities are design flaws in the Wi-Fi standard, any device released after 1997 could be vulnerable. The attack can be executed without special privileges. The attack was detailed on August 5, 2021 at Black Hat Briefings USA and at later at the USENIX 30th Security Symposium, where recordings are shared publicly. The attack does not leave any trace in the network logs. Patches Vanhoef worked with the Wi-Fi Alliance to help vendors issue patches. Microsoft started issuing patches for Windows 7 through Windows 10 on May 11, 2021.

Wi-Fi
Wi-Fi () is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for Wireless LAN, 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, used globally in small office/home office, home and small office networks to link devices and to provide Internet access with wireless routers and wireless access points in public places such as coffee shops, restaurants, hotels, libraries, and airports. ''Wi-Fi'' is a trademark of the Wi-Fi Alliance, which restricts the use of the term "''Wi-Fi Certified''" to products that successfully complete Interoperability Solutions for European Public Administrations, interoperability certification testing. Non-compliant hardware is simply referred to as WLAN, and it may or may not work with "''Wi-Fi Certified''" devices. the Wi-Fi Alliance consisted of more than 800 companies from ar ...
