ALERT: KRACK Vulnerability in WPA2

On Monday, October 16, 2017, a serious vulnerability was discovered and publicly disclosed in the WPA2 encryption protocol. Most wireless devices and routers rely on WPA2 to encrypt Wi-Fi traffic so if you own a wireless device, chances are you may be affected. This vulnerability, known as KRACK (key reinstallation attacks), allows attackers who are physically close enough to connect to your network, to view unencrypted traffic on your network. Previously, it was believed that this traffic was encrypted by WPA2.

This is not a device vulnerability. Instead, it is a weakness in the WPA2 wireless standard. Therefore, if a device supports Wi-Fi, it is most likely affected.

Copper Valley Telecom's Recommendation and Additional Information:

If you have further questions or concerns regarding the KRACK vulnerability, please contact our Solutions team at 907-255-8324.
