Mathy Vanhoef, a well respected Wi-Fi security researcher, has identified a dozen vulnerabilities in the 802.11 protocol called FragAttacks. FragAttacks is short for Fragmentation and Aggregation Attacks. It’s based upon how wireless frames are received and reassembled on a device or access point (AP). Unfortunately, this vulnerability has been present since Wi-Fi existed and nearly all wireless devices are vulnerable to FragAttacks. All security methods are impacted, from WEP to WPA3.
