A series of vulnerabilities, dubbed FragAttacks, has been uncovered in the Wi-Fi specification that could potentially affect billions of devices around the world.
Wi-Fi networks transmit data using a process of frame fragmentation or frame aggregation. FragAttacks, short for fragmentation and aggregation attacks, abuse this process and enable malicious users to insert data into Wi-Fi traffic. It was security researcher Mathy Vanhoe who first brought these vulnerabilities to light.
