How KRACK works: The Key Reinstallation AttaCK isn’t a problem with your device or how it was set up. It’s a problem with the Wi-Fi technology itself. The attack gets between your device and the router and resets the encryption key so hackers can view all network traffic in plain text. This might mean hackers have a front row seat to your credit card numbers, passwords, emails, photos and more. NOTE: The hacker must be in physical range of your Wi-Fi to abuse this flaw. Given most Wi-Fi ranges extend well past your own home/business, this is small comfort, but important to know.
How to protect yourself:
Run Your Updates: Software updates are already being released to fix this flaw. Microsoft has already released one for Windows and Apple has one coming in a few weeks. Take a few minutes to make sure you’re up to date on any device that uses Wi-Fi (your smartphones, laptops, tablets, PCs, game consoles, etc). Unfortunately, some devices may be slow to get an update, or if they’re older, may not get an update to fix this issue at all. If possible, consider using a cabled connection on those older devices or upgrade to one with support.
Be very careful with public Wi-Fi: Be very careful at your local coffee shop. It may be that small shops will not be on top of this type of security. Remember, a hacker only needs to be in the same Wi-Fi area as you to obtain your private information.
Check your browser security: Before sending anything over the internet, check you’re using a HTTPS site. You’ll know these by the little padlock you see next to the URL, and the address will begin with HTTPS. Major sites like Facebook, Gmail and financial institutions already use HTTPS.
