The KRACK vulnerability in wireless internet (WiFi) routers is a very real threat (possibility = HIGH) but unless you’re living next to a 13 year old learning about exploits, the threat is not high for you, your business, or your family (probability = LOW). With that said, you should still update your computers’ operating system and your WiFi routers.
Microsoft has already updated Windows. Apple will update soon. Android and LINUX users seem to be the most vulnerable to this attack. Again, make sure you update your routers as well.
As always, Eckrich Enterprises is ready to help you evaluate your network security (home, mobile, and business).
