Cybersecurity, FragAttacks is a bunch of new vulnerabilities affecting Wi-Fi devices

Mathy Vanhoef discovered the FragAttacks: a series of bugs affecting the Wi-Fi, that can be exploited by an adversary to steal information or attack

“FragAttacks” are a series of bugs affecting the Wi-Fi. They have been discovered by the cybersecurity researcher Mathy Vanhoef. An adversary that is within radio range of a victim can abuse these vulnerabilities to steal user information or attack devices. Three of them are design flaws in the Wi-Fi standard and therefore affect most devices. On top of this, several others were discovered that are caused by widespread programming mistakes in Wi-Fi products. Experiments indicate that every Wi-Fi product is affected by at least one vulnerability and that most products are affected by several vulnerabilities.

The FragAttacks affect all modern security protocols of Wi-Fi, including the latest WPA3 specification

According the cybersecurity expert, the FragAttacks affect all modern security protocols of Wi-Fi, including the latest WPA3 specification. Even the original security one, WEP, is affected. This means that several of the newly discovered design flaws have been part of Wi-Fi since its release in 1997! Fortunately, the design flaws are hard to abuse because doing so requires user interaction or is only possible when using uncommon network settings. As a result, in practice the biggest concern are the programming mistakes in Wi-Fi products since several of them are trivial to exploit.
