An important consumer alert has been issued by Georgia Attorney General Chris Carr in regards to a recent discovery of a WiFi security vulnerability. Key Reinstallation Attack (KRACK) is a WiFi vulnerability that exists in almost every WiFi network, even networks utilizing WPA2 security. You can read in more detail about KRACK HERE or a quick overview HERE.
AG Carr recommends the following:
- Update your smartphone to the most recent operating system.
- Restart your computer daily and allow updates to install.
- Refrain from using your laptop or smartphone on public wireless networks until you verify that a patch is installed on your device; consider using your cellular network to connect instead.
- Continue to use “WPA2” because it is still the most secure WiFi protocol currently available, according to experts
It is not listed in the suggestions, but I highly recommend updating the firmware on your WiFi router/modem ASAP. You can brick (totally mess up) your device if you don’t know what you are doing, so please utilize a professional if you are not comfortable with the process.
