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. References External links * Fragment and Forge: Breaking Wi-Fi Through Frame Aggregation and Fragmentation

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 ...

Black Hat Briefings
Black Hat Briefings (commonly referred to as Black Hat) is a computer security conference that provides security consulting, training, and briefings to hackers, corporations, and government agencies around the world. Black Hat brings together a variety of people interested in information security ranging from non-technical individuals, executives, hackers, and security professionals. The conference takes place regularly in Las Vegas, Barcelona, London and Riyadh but has also been hosted in Amsterdam, Tokyo, and Washington, D.C. in the past. History The first Black Hat was held July 7-10, 1997 in Las Vegas, immediately prior to DEF CON 5. The conference was aimed at the computer industry, promising to give them privileged insight into the minds and motivations of their hacker adversaries. Its organizers stated: "While many conferences focus on information and network security, only the Black Hat Briefings will put your engineers and software programmers face-to-face with to ...

USENIX
USENIX is an American 501(c)(3) nonprofit membership organization based in Berkeley, California and founded in 1975 that supports advanced computing systems, operating system (OS), and computer networking research. It organizes several conferences in these fields. History USENIX was established in 1975 under the name "Unix Users Group," focusing primarily on the study and development of the Unix OS family and similar systems. In June 1977, a lawyer from AT&T Corporation informed the group that they could not use the word "Unix" in their name as it was a trademark of Western Electric (the manufacturing arm of AT&T until 1995), which led to the change of name to USENIX. Since its founding, it has published a technical journal titled '' ;login:''. USENIX was started as a technical organization. As commercial interest grew, a number of separate groups started in parallel, most notably the Software Tools Users Group (STUG), a technical adjunct for Unix-like tools and interfac ...

Wi-Fi Alliance
The Wi-Fi Alliance is a non-profit organization that owns the Wi-Fi trademark. Manufacturers may use the trademark to brand products certified for Wi-Fi interoperability. It is based in Austin, Texas. History Early IEEE 802.11, 802.11 products suffered from interoperability problems because the Institute of Electrical and Electronics Engineers (IEEE) had no provision for testing equipment for compliance with its standards. In 1999, pioneers of a new, higher-speed variant endorsed the IEEE 802.11b specification to form the Wireless Ethernet Compatibility Alliance (WECA) and branded the new technology Wi-Fi. The group of companies included 3Com, Aironet (acquired by Cisco), Harris Semiconductor (now Intersil), Lucent Technologies (the WLAN part was renamed as Orinoco, become part of Avaya, then acquired by Extreme Networks), Nokia and Symbol Technologies (acquired by Motorola, Zebra Technologies, and now Extreme Networks). The alliance lists Apple Inc., Apple, Comcast, Samsung ...

Computer Security Exploits
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (''computation''). Modern digital electronic computers can perform generic sets of operations known as ''programs'', which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots. Computers are at the core of general-purpose devices such as personal computers and mobile devices such as smartphones. Computers power the Internet, which links billions of computer ...
