Wi-Fi FragAttacks


On May 11th, 2021, Mathy Vanhoef (New York University Abu Dhabi) published a new paper on a number of vulnerabilities he has discovered within the base 802.11 protocol (802.11 is the standard that Wi-Fi is built on). Mathy is not new to the world of Wi-Fi research, having published previous papers you might have heard of. KRACK in 2017 with 10 unique vulnerabilities with WPA2-PSK and then Dragonblood in 2019 with an additional 14 unique vulnerabilities with WPA3-SAE. For this report, known as “FragAttacks”, Mathy has focused not on the encryption used to secure Wi-Fi communications but on the way that stations (both APs and client devices, or “STAs”) handle breaking down and then reassembling the data they are sending over the air.
