WiFi KRACK - Wireless Security Protocol Breach.
The long used WPA2-PSK protocol has been breached... but LUCKILY, there's a relatively easy fix IF you're using some of the more widely used brands of Access Points.
Ubiquiti (Unifi), Aruba, and Aerohive - the main brands Cloud 9 customers use - already have patches. Chances are that we've already contacted you to update them, or went ahead and updated them in the background.
What you need to know: Your Windows computer is most likely already safe and you Mac will be soon. Apple is rushing to fix, so look for an OS update soon.
ZDNet has a great article on it that's also keeping up with who has what fixes: http://www.zdnet.com/article/here-is-every-patch-for-krack-wi-fi-attack-available-right-now/
