Jonathan Knight always has loved to fix things. Growing up on a farm in Elkview, he always had something that needed to be repaired. So, he learned a lot of electrical and mechanical skills out of necessity. And, he learned as he went. He didn’t have the internet, so most of his beginning knowledge came from the encyclopedia. He says he “would’ve been dangerous” if he had the internet available as a kid.

On October 16, 2017, Belgian security researchers made public their findings that demonstrated fundamental design flaws in WPA2 that could lead to man-in-the-middle (MITM) attacks on wireless networks.

Named KRACKs, or key reinstallation attacks, this technique can theoretically be used by attackers to steal sensitive information from unsuspecting wireless users leveraging these flaws in the WiFi standard. Based on their research, CERT issued a series of CVEs to address this flaw, and most vendors affected have issued patches as of this writing.

On Tuesday, October 17th, I was invited to appear on 580 WCHS’s Ask the Expert show to talk to their audience about cybersecurity. I took the opportunity to bring along our Director of Information Security Services, Rob Dixon.
