Security Flaws in WPA3 Protocol Let Attackers Hack WiFi Password

[ April 12 , 2019 ]

Researchers have unveiled several serious vulnerabilities in the wireless security protocol that could allow attackers to recover the password of the Wi-Fi network.

Concretely, attackers can then read information that WPA3 was assumed to safely encrypt. This can be abused to steal sensitive transmitted information such as credit card numbers, passwords, chat messages, emails, and so on,” the researchers say.

The Wi-Fi Protected Access III (WPA3) protocol was launched in an attempt to address technical shortcomings of the WPA2 protocol from the ground, which has long been considered to be insecure and found vulnerable to KRACK (Key Reinstallation Attack).

Researchers also detail two side-channel attacks—Cache-based (CVE-2019-9494) and Timing-based (CVE-2019-9494) attacks—against Dragonfly’s password encoding method that could allow attackers to perform a password partitioning attack, similar to an offline dictionary attack, to obtain Wi-Fi password.
