A number of vulnerabilities in a majority of Wi-Fi products have likely left users open to attacks and millions of devices are believed to be impacted. The flaws named FragAttacks were discovered by cybersecurity expert Mathy Vanhoef, a postdoctoral researcher at the New York University of Abu Dhabi. Vanhoef previously highlighted Kracattacks, which were a serious flaw in WPA2, a protocol used to secure protected Wi-Fi networks.
‘FragAttacks’ or fragmentation and aggregation attacks, allow an attacker who is within range of one’s Wi-Fi device to steal user information, including sensitive information such as passwords. According to the researcher, while three are design flaws in the Wi-Fi standard, “several other vulnerabilities were discovered that are caused by widespread programming mistakes in Wi-Fi products.”
