Dear Customer,
Please see the attached Voalte Support Bulletin for further details on the Wi-Fi encryption vulnerabilities. Earlier this week, severe security vulnerabilities with WPA/WPA2 encryption protocol for Wi-Fi were discovered.
The vulnerabilities are called key reinstallation attacks (KRACKs), and center around the process used for negotiating the handshake between client and access point, especially step three of the four-way handshake.
