My phone is at risks, how do I make a krack disappear off my phone
[Edit: Clarified subject]
The only way to remove the Krack vulnerability is with an OS update from the device's manufacturer. Unfortunately, if you are seeing this message on your device, the device is probably too old for the manufacturer to continue updating the OS.So you will continue to see the message in the Device Security section of the Security area of your 360.
The good news is that your 360 will help protect against this vulnerability.
