Summarized, the Dragonfly handshake of WPA3 and EAP-pwd is supposed to prevent dictionary attacks. However, we discovered design flaws that still enable an adversary to perform dictionary attacks. In particular, we discovered the following design flaws in WPA3 and EAP-pwd:
We also discovered the following implementation flaws in EAP-pwd and WPA3 products:
After our first disclosure, the Wi-Fi Alliance released security guidelines on how to implement WPA3. Unfortunately, these guidelines still contained flaws. Summarized, we found that:
The design issues in WPA3 and EAP-pwd allow an adversary to perform dictionary (and brute-force) attacks on the password.
The invalid curve attacks against all EAP-pwd and selected WPA3 implementations allow an adversary to bypass authentication.
The impact of other vulnerabilities is summarized above and also explained on our website.
