![]() The client device will then attempt to connect again using a different security group. Dragonblood also covers a security group downgrade attack which allows those using an evil twin attack to decline initial requests for WPA3 security protections. What’s the legitimate one and which is the evil twin one? It’s hard for a device or human being to tell.”īut WPA3’s Transition Mode isn’t its only weak point for potential downgrade attacks. “You’re bringing in an evil twin access point that’s broadcasting a WPA2 version of the Wi-Fi network and victim devices don’t know the difference. “You’ve now launched the beginning of a Dragonblood attack,” Orsi continued. That’s great for encouraging the uptake to WPA3 without forcing people to do so immediately, and accommodates older client devices, but it’s a weak point in the new security standard which leaves everyone vulnerable. It’s known as WPA3-Transition Mode, and allows a network to operate WPA3 and WPA2 protections with the same password. Even if the potential victim can support WPA3 on their device, you’ve effectively downgraded them to WPA2 thanks to WPA3’s backwards compatibility. This attack could be carried out with a smartphone that only supports WPA2. WatchGardĪlthough users connecting to your spoofed, evil twin network are giving away a lot of their information by using it, they are potentially weakening their security even more. ![]() Your phone is broadcasting the exact same Wi-Fi network.” Ryan Orsi, director of product management at WatchGuard. You look at the name of that Wi-Fi network if you change your phone’s name to and you turn on your hotspot, you have just launched an evil twin attack. “ you have a smartphone and take it out of your pocket, walk in your office and it has a WPA3 password protected Wi-Fi network. “The biggest flaw that’s been around in Wi-Fi for 20 years is that you, me, my sister (who isn’t technical) can all launch an evil twin attack just by using our cellphones,” WatchGuard Technologies’ director of product management, Ryan Orsi, told Digital Trends. There are six problems highlighted by Mathy Vanhoef in his Dragonblood exposé, but almost all of them are made possible by an age-old Wi-Fi hacking technique called an evil twin. ![]() These exploits have been collected under the banner name of Dragonblood and unless addressed, they could mean that WPA3 isn’t that much more secure than WPA2, because the methods used to circumvent its protections haven’t really changed. Fitbit Versa 3īut Dragonfly and WPA3 itself are also vulnerable to some dangerous flaws of their own and some of the worst ones have been present in WPA protected networks since their inception. ![]()
