The Key Reinstallation Attack (named KRACK by its authors) was published earlier this week by security researchers. It allows attackers within range of a WiFi access point the ability to monitor data sent between a WiFi client and an Access Point. 

 

Our analysis of this exploit is that Cradlepoint router AP functionality is not at risk, but WiFi-as-WAN and WiFi Client Mode functionality is at risk.  Along with our Wireless driver vendors and WiFi Authentication services, we are updating our routers to mitigate this issue.
