In the early 2000s, you probably remember when researchers discovered some vulnerabilities that put the nail in the coffin of Wired Equivalent Privacy (WEP), a security protocol used to protect Wi-Fi communications. Essentially, this WEP vulnerability meant that attackers could quickly crack WEP encryption, and see all your wireless traffic. At the time, this flaw caused a major uproar, and forced the industry to design a new Wi-Fi security protocol, Wi-Fi Protected Access (WPA).
Unfortunately, a Belgian researcher has found a number of vulnerabilities in WPA2’s 4-way handshake. Like the WEP issue, these flaws could allow wireless hackers to decrypt your employees’ Wi-Fi communications. The good news is, unlike the WEP vulnerability, you can patch these WPA2 problems. Watch today’s Daily Byte video to learn a bit more about the Krack WPA2 attacks, and what you can do about them. I also recommend you check out the reference section below for links to much more information.

Hi Corey,
I am a bit upset about the patch not being available until October 30th
That said….. you mention use VPN when connected to internet. Could you please expand on that?
Do you mean the sslvpn watchguard app for windows????
