Researcher: Supposedly secure wifi networks vulnerable to 'KRACK' attack

Researcher: Supposedly secure wifi networks vulnerable to 'KRACK' attack We didn’t have to look very hard for today’s top story: a Belgian researcher says pretty much every modern wifi network out there is vulnerable to hackers, and sorry, that fancy “WPA2” password is not going to protect your network. Called the “KRACK attack,” a funny name for the “Key Reinstallation Attack,” the security hole will allegedly allow hackers to see anything and everything a wifi user is doing online.

The vulnerability was actually first detailed last May, and researcher Mathy Vanhoef says that since then, they’ve been able to refine the attack even more and that pretty much no wifi network is safe. If exploited, Vanhoef says the KRACK attack lets hackers “steal sensitive information such as credit card numbers, passwords, chat messages, emails, photos, and so on.” He says the attack works against all modern protected Wi-Fi networks.

Vanhoef also said the vulnerability was especially bad for Android and Linux users, but that essentially, all computers on all wifi networks can be affected. They even put together a video on how it works. So what to do? Not much you can do right now except run those software updates… just as soon as they come out from the parties involved. Meanwhile, you might want to think about plugging you PC in with that dusty CAT 5 cable. Source:
