Security flaw in Wi-Fi affects several Android and iOS devices. Know if yours is on the list

Security company ESET has just published the discovery of a new flaw in the Wi-Fi chips of various devices. This was nicknamed KrØØk and affects both Android and iOS devices.

This vulnerability affects the WPA2 protocol, one of the most widely used today. It is estimated to affect billions of users worldwide and is not limited to smartphones or tablets. Also routers from Asus or Huawei are vulnerable.

Smartphones and tablets vulnerable to KrØØk

  • Amazon Echo 2nd gen
  • Amazon Kindle 8th gen
  • Apple iPad mini 2
  • Apple iPhone 6
  • Apple iPhone 6S
  • Apple iPhone 8
  • Apple iPhone XR
  • Apple MacBook
  • Apple iPad Air
  • Google Nexus 5
  • Google Nexus 6
  • Google Nexus 6P
  • Raspberry Pi 3
  • Samsung Galaxy S4
  • Samsung Galaxy S8
  • Xiaomi Redmi 3S


As you can see, we have in this list a number of extremely popular equipment that have boosted the spread of KrØØk. One of the most egregious cases is the iPhone XR which was, nothing more, nothing less than the best selling smartphone in the world in 2019.

KrØØk allows access to encrypted communications

When we see an application that promises data encryption, we tend to get more out of it when using it. However, none of this will be of real value if your equipment has been affected by this vulnerability.

This is because the chips in question are not deleting our data when we disconnect from the network. This means that they can be broadcast again on the network, which means that hackers nor do they need to be on the same network as you to access your information.

Update can solve the problem

Through the disclosure of these data, the target companies have already started to develop corrections for the problem. Therefore, it is extremely important that, if your equipment is on this list, keep it updated.

However, a simple update to your smartphone will not be enough to have your data safe again. If your router is one of the vulnerable ones, it will also need to be updated so that your data is safe again.
