With the flaw completely open, it puts businesses and everyone at risk of having their personal information hacked in to. With the ability to decrypt traffic, they will be able to get access to anyone’s bank details which can have severe and disastrous results.

What to do?

There’s not a great deal you can physically do with this issue as it is up to the network providers and large businesses to deal with the issue. The main thing to do is just to be vigilant and aware when connecting to Wi-Fi networks as some may not have the issue patched up yet.

They will have to go through a pathway by connecting to the access point of the network by being within certain distance from it to successfully hack the network. So it’s not all that bad, but nobody can take a risk and leave it as there could be some form of solution around it.
