While assessing a corporate office that recently migrated from WPA2-Personal to WPA3-Personal, you try to capture the network's authentication exchange for later password cracking but discover that the packets do not yield any reusable hashes. Which specific attack vector has WPA3's Simultaneous Authentication of Equals (SAE) handshake been designed to thwart compared with WPA2?
Flooding the channel with forged beacon frames to cause denial of service
Injecting crafted frames to exploit client-side driver vulnerabilities
Spoofing deauthentication frames to force clients off the network
Conducting offline dictionary attacks against captured handshakes
WPA2-Personal uses the four-way handshake, which can be captured once and then subjected to unlimited offline dictionary or brute-force attempts against the pre-shared key. WPA3-Personal replaces this with the Dragonfly-based SAE handshake. SAE forces an interactive exchange for every password guess, preventing attackers from performing large-scale offline dictionary attacks on a single captured transcript. Packet injection, deauthentication spoofing, and beacon flooding are separate wireless threats that SAE does not specifically mitigate.
