A group of vulnerabilities being called Dragonblood is targeting the newly released WPA3 WiFi security and authentication standard released by WiFi Alliance. The Dragonblood vulnerabilities include a few different attack vectors such as a DoS vulnerability, two side-channel information leaks, and two downgrade vulnerabilities. If the vulnerabilities are able to be exploited, an attacker would be able to obtain the WiFi password and invade a targeted network. The DoS attack is the least threatening of the five vulnerabilities because it simply crashes WPA-3 consistent access points. All four of the other vulnerabilities take advantage of the flaws in the Dragonfly key exchange, a tool that’s implemented to allow users to authenticate on WPA3 access points or routers. As far as the downgrade attacks go, attackers can trick the network into using an out-of-date password exchange system which allows them to exploit old flaws and retrieve network passwords. In the side-channel information attack, WiFi WPA3-capable networks can be fooled into using weak algorithms, and while it doesn’t leak the whole thing, with continued attacks, criminals could end up with the whole network password.
